Actemra


Pronunciation: TOE-si-LIZ-oo-mab
Generic Name: Tocilizumab
Brand Name: Actemra

Patients who use Actemra have an increased risk of developing serious and sometimes fatal infections, including tuberculosis (TB), fungal infection, and other types of infection. Most patients who developed these infections were also taking medicine that suppressed their immune system (eg, corticosteroids, methotrexate).


Patients should receive a TB skin test before using Actemra. Patients who test positive for TB should begin treatment for TB before starting Actemra. All patients should also be monitored for signs of TB while using Actemra even if their TB test is negative.


Contact your doctor immediately if you develop signs of TB or any other type of infection (eg, persistent cough; muscle weakness; unexplained weight loss; fever, chills, or persistent sore throat; shortness of breath; unusual tiredness; warm, red, or painful skin or sores; increased or painful urination; severe or persistent diarrhea; blood in the mucus).





Actemra is used for:

Treating moderate to severe rheumatoid arthritis (RA) in certain patients. It is also used to treat systemic juvenile idiopathic arthritis (SJIA) in children 2 years and older. It may be used alone or in combination with other medicine. It may also be used for other conditions as determined by your doctor.


Actemra is an interleukin-6 (IL-6) receptor blocker. It works by blocking a substance (IL-6) in the body that contributes to inflammation.


Do NOT use Actemra if:


  • you are allergic to any ingredient in Actemra

  • you have a severe infection (eg, sepsis) or any other active infection

  • you have active liver problems

  • you are using abatacept, anakinra, an anti-CD20 monoclonal antibody (eg, rituximab), or a tumor necrosis factor (TNF) blocker (eg, adalimumab)

Contact your doctor or health care provider right away if any of these apply to you.



Before using Actemra:


Some medical conditions may interact with Actemra. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you have low blood platelet or neutrophil levels; a history of hepatitis B infection or other liver problems; stomach or bowel problems (eg, diverticulitis, pain, bleeding, perforation, inflammation, ulcer); high cholesterol; high blood pressure; diabetes; kidney problems; cancer; or numbness, tingling, or other nervous system problems (eg, multiple sclerosis [MS], Guillain-Barré syndrome)

  • if you have an infection, open cuts or sores on your body, flu-like symptoms or other signs of infection (eg, fever; chills; cough; warm, red, or painful skin), shingles, or are using medicine to treat an infection

  • if you have a history of an infection that keeps coming back, TB infection, or a positive TB skin test

  • if you have ever lived in or traveled to an area where TB is common, or if you have come into close contact with a person with active TB

  • if you have ever lived or traveled to certain parts of the country (eg, Ohio or Mississippi river valleys, the Southwest) where certain types of fungal infections (eg, histoplasmosis, coccidioidomycosis, blastomycosis) are common. Check with your doctor if you are not sure if you have lived in an area where these infections are common

  • if you have HIV, a weakened immune system, or you take medicine that may weaken your immune system (eg, cyclosporine)

  • if you have recently received or are scheduled to receive a vaccine, or are using another medicine to treat RA

  • if you will be having surgery or a medical procedure

Some MEDICINES MAY INTERACT with Actemra. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Abatacept, anakinra, an anti-CD20 monoclonal antibody (eg, rituximab), corticosteroids (eg, prednisone), methotrexate, or TNF blockers (eg, adalimumab) because the risk of serious infection may be increased

  • Medicines that may harm the liver (eg, acetaminophen, methotrexate, ketoconazole, isoniazid, certain medicines for HIV infection) because the risk of liver side effects may be increased. Ask your doctor if you are unsure if any of your medicines might harm the liver

  • Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen) because the risk of severe stomach problems may be increased

  • Cyclosporine, HMG-CoA reductase inhibitors (eg, atorvastatin), oral contraceptives (birth control pills), theophylline, or warfarin because their effectiveness may be decreased by Actemra

This may not be a complete list of all interactions that may occur. Ask your health care provider if Actemra may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

Diprosalic Ointment





1. Name Of The Medicinal Product



Diprosalic Ointment


2. Qualitative And Quantitative Composition



Betamethasone Dipropionate 0.064% w/w*



(* equivalent to 0.05% Betamethasone)



Salicylic Acid 3.00% w/w



3. Pharmaceutical Form



Ointment



4. Clinical Particulars



4.1 Therapeutic Indications



Betamethasone Dipropionate is a synthetic fluorinated corticosteroid. It is active topically and produces a rapid and sustained response in those inflammatory dermatoses that are normally responsive to topical corticosteroid therapy, and it is also effective in the less responsive conditions, such as psoriasis of the scalp, chronic plaque psoriasis of the hands and feet, but excluding widespread plaque psoriasis.



Topical salicylic acid softens keratin, loosens cornified epithelium and desquamates the epidermis.



Diprosalic presentations are therefore indicated for the treatment of hyperkeratotic and dry corticosteroid-responsive dermatoses where the cornified epithelium may resist penetration of the steroid. The salicylic acid constituent of Diprosalic preparations, as a result of its descaling action, allows access of the dermis more rapidly than by applying steroid alone.



4.2 Posology And Method Of Administration



Adults :



Once to twice daily. In most cases a thin film should be applied to cover the affected area twice daily.



For some patients adequate maintenance therapy may be achieved with less frequent application.



It is recommended that Diprosalic preparations are prescribed for two weeks, and that treatment is reviewed at that time. The maximum weekly dose should not exceed 60g.



Children :



Dosage in children should be limited to 5 days.



4.3 Contraindications



Rosacea, acne, perioral dermatitis, perianal and genital pruritus. Hypersensitivity to any of the ingredients of the Diprosalic presentations contra-indicates their use as does tuberculous and most viral lesions of the skin, particularly herpes simplex, vacinia, varicella. Diprosalic should not be used in napkin eruptions, fungal or bacterial skin infections without suitable concomitant anti-infective therapy.



4.4 Special Warnings And Precautions For Use



Occlusion must not be used, since under these circumstances the keratolytic action of salicylic acid may lead to enhanced absorption of the steroid.



Local and systemic toxicity is common, especially following long continuous use on large areas of damaged skin, in flexures or with polythene occlusion. If used in children or on the face courses should be limited to 5 days. Long term continuous therapy should be avoided in all patients irrespective of age.



Topical corticosteroids may be hazardous in psoriasis for a number of reasons, including rebound relapses following development of tolerance, risk of generalised pustular psoriasis and local systemic toxicity due to impaired barrier function of the skin. Careful patient supervision is important.



It is dangerous if Diprosalic presentations come into contact with the eyes. Avoid contact with the eyes and mucous membranes.



The systemic absorption of betamethasone dipropionate and salicylic acid may be increased if extensive body surface areas or skin folds are treated for prolonged periods or with excessive amounts of steroids. Suitable precautions should be taken in these circumstances, particularly with infants and children.



If irritation or sensitization develops with the use of Diprosalic Ointment and Lotion, treatment should be discontinued.



Any side effects that are reported following systemic use of corticosteroids, including adrenal suppression, may also occur with topical corticosteroids, especially in infants and children.



If excessive dryness or increased skin irritation develops, discontinue use of this preparation.



Peadiatric Use: Peadiatric patients may demonstrate greater susceptibility to topical corticosteroid-induced hypothalamic-pituary-adrenal (HPA) axis suppression and to exogenous corticosteroid effects than mature patients because of greater absorption due to a large skin surface area to body weight ratio.



HPA axis suppression, Cushing's syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include low plasma cortisol levels and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include a bulging fontanelle, headaches and bilateral papilledema.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



None stated



4.6 Pregnancy And Lactation



Since safety of topical corticosteroid use in pregnant women has not been established, drugs of this class should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus. Drugs of this class should not be used extensively in large amounts or for prolonged periods of time in pregnant patients.



Since it is not known whether topical administration of corticosteroids can result in sufficient systemic absorption to produce detectable quantities in breast milk, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.



4.7 Effects On Ability To Drive And Use Machines



None stated.



4.8 Undesirable Effects



Diprosalic skin preparations are generally well tolerated and side-effects are rare.



Continuous application without interruption may result in local atrophy of the skin, striae and superficial vascular dilation, particularly on the face.



Adverse reactions that have been reported with the use of topical corticosteroids include: burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis and allergic contact dermatitis.



The following may occur more frequently with the use of occlusive dressings: maceration of the skin, secondary infection, skin atrophy, striae and miliaria.



In addition, prolonged use of salicylic acid preparations may cause dermatitis.



4.9 Overdose



Excessive prolonged use of topical corticosteroids can suppress pituitary-adrenal functions resulting in secondary adrenal insufficiency, and produce manifestations of hypercorticism, including Cushing's disease.



Treatment: Appropriate symptomatic treatment is indicated. Acute hypercorticoid symptoms are usually reversible. Treat electrolyte imbalance, if necessary. In case of chronic toxicity, slow withdrawal of corticosteroids is advised.



With topical preparations containing salicylic acid excessive prolonged use may result in symptoms of salicyclism. Treatment is symptomatic. Measures should be taken to rid the body rapidly of salicylate. Adminster oral sodium bicarbonate to alkalinize the urine and force diuresis.



The steroid content of each tube is so low as to have little or no toxic effect in the unlikely event of accidental oral ingestion.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Diprosalic preparations contain the dipropionate ester of betamethasone which is a glucocorticoid exhibiting the general properties of corticosteroids, and salicylic acid which has keratolytic properties.



Salicylic acid is applied topically in the treatment of hyperkeratotic and scaling conditions where its keratolytic action facilitates penetration of the corticosteroid.



In pharmacological doses, corticosteroids are used primarily for their anti-inflammatory and/or immune suppressive effects.



Topical corticosteroids such as betamethasone dipropionate are effective in the treatment of a range of dermatoses because of their anti-inflammatory, anti-pruritic and vasoconstrictive actions. However, while the physiologic, pharmacologic and clinical effects of the corticosteroids are well known, the exact mechanisms of their action in each disease are uncertain.



5.2 Pharmacokinetic Properties



Salicylic acid exerts only local action after topical application.



The extent of percutaneous absorption of topical corticosteroids is determined by many factors including vehicle, integrity of the epidermal barrier and the use of occlusive dressings.



Topical corticosteroids can be absorbed through intact, normal skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.



Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids.



Once absorbed through the skin, topical corticosteroids enter pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees, are metabolised primarily in the liver and excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted in the bile.



5.3 Preclinical Safety Data



There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.

Azelex



azelaic acid

Dosage Form: cream
Azelex®

(azelaic acid cream) 20%

For Dermatologic Use Only

Not for Ophthalmic Use



DESCRIPTION


Azelex® (azelaic acid cream) 20% contains azelaic acid, a naturally occurring saturated dicarboxylic acid.


Structural Formula: HOOC-(CH2)7-COOH


Chemical Name: 1,7-heptanedicarboxylic acid


Empirical Formula: C9H16O4


Molecular Weight: 188.22



Active Ingredient: Each gram of Azelex® contains azelaic acid......... 0.2 gm (20% w/w).



Inactive Ingredients: cetearyl octanoate; glycerin; glyceryl stearate and cetearyl alcohol and cetyl palmitate and cocoglycerides; PEG-5 glyceryl stearate; propylene glycol; and purified water. Benzoic acid is present as a preservative.



CLINICAL PHARMACOLOGY


The exact mechanism of action of azelaic acid is not known. The following in vitro data are available, but their clinical significance is unknown. Azelaic acid has been shown to possess antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis. The antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis.


A normalization of keratinization leading to an anticomedonal effect of azelaic acid may also contribute to its clinical activity. Electron microscopic and immunohistochemical evaluation of skin biopsies from human subjects treated with Azelex® Cream demonstrated a reduction in the thickness of the stratum corneum, a reduction in number and size of keratohyalin granules, and a reduction in the amount and distribution of filaggrin (a protein component of keratohyalin) in epidermal layers. This is suggestive of the ability to decrease microcomedo formation.



Pharmacokinetics: Following a single application of Azelex® Cream to human skin in vitro, azelaic acid penetrates into the stratum corneum (approximately 3 to 5% of the applied dose) and other viable skin layers (up to 10% of the dose is found in the epidermis and dermis). Negligible cutaneous metabolism occurs after topical application. Approximately 4% of the topically applied azelaic acid is systemically absorbed. Azelaic acid is mainly excreted unchanged in the urine but undergoes some β-oxidation to shorter chain dicarboxylic acids. The observed half-lives in healthy subjects are approximately 45 minutes after oral dosing and 12 hours after topical dosing, indicating percutaneous absorption rate-limited kinetics.


Azelaic acid is a dietary constituent (whole grain cereals and animal products), and can be formed endogenously from longer-chain dicarboxylic acids, metabolism of oleic acid, and ψ-oxidation of monocarboxylic acids. Endogenous plasma concentration (20 to 80 ng/mL) and daily urinary excretion (4 to 28 mg) of azelaic acid are highly dependent on dietary intake. After topical treatment with Azelex® Cream in humans, plasma concentration and urinary excretion of azelaic acid are not significantly different from baseline levels.



INDICATIONS AND USAGE


Azelex® Cream is indicated for the topical treatment of mild-to-moderate inflammatory acne vulgaris.



CONTRAINDICATIONS


Azelex® Cream is contraindicated in individuals who have shown hypersensitivity to any of its components.



WARNINGS


Azelex® Cream is for dermatologic use only and not for ophthalmic use.


There have been isolated reports of hypopigmentation after use of azelaic acid. Since azelaic acid has not been well studied in patients with dark complexions, these patients should be monitored for early signs of hypopigmentation.



PRECAUTIONS



General:


If sensitivity or severe irritation develop with the use of Azelex® Cream, treatment should be discontinued and appropriate therapy instituted.



Information for patients:


Patients should be told:


  1. To use Azelex® Cream for the full prescribed treatment period.

  2. To avoid the use of occlusive dressings or wrappings.

  3. To keep Azelex® Cream away from the mouth, eyes and other mucous membranes. If it does come in contact with the eyes, they should wash their eyes with large amounts of water and consult a physician if eye irritation persists.

  4. If they have dark complexions, to report abnormal changes in skin color to their physician.

  5. Due in part to the low pH of azelaic acid, temporary skin irritation (pruritus, burning, or stinging) may occur when Azelex® Cream is applied to broken or inflamed skin, usually at the start of treatment. However, this irritation commonly subsides if treatment is continued. If it continues, Azelex® Cream should be applied only once-a-day, or the treatment should be stopped until these effects have subsided. If troublesome irritation persists, use should be discontinued, and patients should consult their physician.


(See ADVERSE REACTIONS.)

Carcinogenesis, mutagenesis, impairment of fertility:


Azelaic acid is a human dietary component of a simple molecular structure that does not suggest carcinogenic potential, and it does not belong to a class of drugs for which there is a concern about carcinogenicity. Therefore, animal studies to evaluate carcinogenic potential with Azelex® Cream were not deemed necessary. In a battery of tests (Ames assay, HGPRT test in Chinese hamster ovary cells, human lymphocyte test, dominant lethal assay in mice), azelaic acid was found to be nonmutagenic. Animal studies have shown no adverse effects on fertility.



Pregnancy:


Teratogenic Effects: Pregnancy Category B.

Embryotoxic effects were observed in Segment I and Segment II oral studies with rats receiving 2500 mg/kg/day of azelaic acid. Similar effects were observed in Segment II studies in rabbits given 150 to 500 mg/kg/day and in monkeys given 500 mg/kg/day. The doses at which these effects were noted were all within toxic dose ranges for the dams. No teratogenic effects were observed. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.



Nursing Mothers:


Equilibrium dialysis was used to assess human milk partitioning in vitro. At an azelaic acid concentration of 25 μg/mL, the milk/plasma distribution coefficient was 0.7 and the milk/buffer distribution was 1.0, indicating that passage of drug into maternal milk may occur. Since less than 4% of a topically applied dose is systemically absorbed, the uptake of azelaic acid into maternal milk is not expected to cause a significant change from baseline azelaic acid levels in the milk. However, caution should be exercised when Azelex® Cream is administered to a nursing mother.



Pediatric Use:


Safety and effectiveness in pediatric patients under 12 years of age have not been established.



Geriatric Use:


Clinical studies of Azelex® Cream did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.



Adverse Reactions


During U.S. clinical trials with Azelex®Cream, adverse reactions were generally mild and transient in nature. The most common adverse reactions occurring in approximately 1-5% of patients were pruritus, burning, stinging and tingling. Other adverse reactions such as erythema, dryness, rash, peeling, irritation, dermatitis, and contact dermatitis were reported in less than 1% of subjects. There is the potential for experiencing allergic reactions with use of Azelex®Cream.


In patients using azelaic acid formulations, the following additional adverse experiences have been reported rarely: worsening of asthma, vitiligo depigmentation, small depigmented spots, hypertrichosis, reddening (signs of keratosis pilaris), and exacerbation of recurrent herpes labialis.



DOSAGE AND ADMINISTRATION


After the skin is thoroughly washed and patted dry, a thin film of Azelex® Cream should be gently but thoroughly massaged into the affected areas twice daily, in the morning and evening. The hands should be washed following application. The duration of use of Azelex® Cream can vary from person to person and depends on the severity of the acne. Improvement of the condition occurs in the majority of patients with inflammatory lesions within four weeks.

Protopic 0.03% ointment (Astellas Pharma Ltd)





1. Name Of The Medicinal Product



Protopic 0.03% ointment


2. Qualitative And Quantitative Composition



1 g of Protopic 0.03% ointment contains 0.3 mg of tacrolimus as tacrolimus monohydrate (0.03%).



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Ointment



A white to slightly yellowish ointment.



4. Clinical Particulars



4.1 Therapeutic Indications



Protopic 0.03% ointment is indicated in adults, adolescents and children from the age of 2 years.



Flare treatment



Adults and adolescents (16 years of age and above)



Treatment of moderate to severe atopic dermatitis in adults who are not adequately responsive to or are intolerant of conventional therapies such as topical corticosteroids.



Children (2 years of age and above)



Treatment of moderate to severe atopic dermatitis in children who failed to respond adequately to conventional therapies such as topical corticosteroids.



Maintenance treatment



Treatment of moderate to severe atopic dermatitis for the prevention of flares and the prolongation of flare-free intervals in patients experiencing a high frequency of disease exacerbations (i.e. occurring 4 or more times per year) who have had an initial response to a maximum of 6 weeks treatment of twice daily tacrolimus ointment (lesions cleared, almost cleared or mildly affected).



4.2 Posology And Method Of Administration



Protopic treatment should be initiated by physicians with experience in the diagnosis and treatment of atopic dermatitis.



Protopic is available in two strengths, Protopic 0.03% and Protopic 0.1% ointment.



Posology



Flare treatment



Protopic can be used for short-term and intermittent long-term treatment. Treatment should not be continuous on a long-term basis.



Protopic treatment should begin at the first appearance of signs and symptoms. Each affected region of the skin should be treated with Protopic until lesions are cleared, almost cleared or mildly affected. Thereafter, patients are considered suitable for maintenance treatment (see below). At the first signs of recurrence (flares) of the disease symptoms, treatment should be re-initiated.



Adults and adolescents (16 years of age and above)



Treatment should be started with Protopic 0.1% twice a day and treatment should be continued until clearance of the lesion. If symptoms recur, twice daily treatment with Protopic 0.1% should be restarted. An attempt should be made to reduce the frequency of application or to use the lower strength Protopic 0.03% ointment if the clinical condition allows.



Generally, improvement is seen within one week of starting treatment. If no signs of improvement are seen after two weeks of treatment, further treatment options should be considered.



Elderly patients



Specific studies have not been conducted in elderly patients. However, the clinical experience available in this patient population has not shown the necessity for any dosage adjustment.



Paediatric population



Children (2 years of age and above) should use the lower strength Protopic 0.03% ointment.



Treatment should be started twice a day for up to three weeks. Afterwards the frequency of application should be reduced to once a day until clearance of the lesion (see section 4.4).



Protopic ointment should not be used in children aged below 2 years until further data are available.



Maintenance treatment



Patients who are responding to up to 6 weeks treatment using tacrolimus ointment twice daily (lesions cleared, almost cleared or mildly affected) are suitable for maintenance treatment.



Adults and adolescents (16 years of age and above)



Adult patients should use Protopic 0.1% ointment.



Protopic ointment should be applied once a day twice weekly (e.g. Monday and Thursday) to areas commonly affected by atopic dermatitis to prevent progression to flares. Between applications there should be 2–3 days without Protopic treatment.



After 12 months treatment, a review of the patient`s condition should be conducted by the physician and a decision taken whether to continue maintenance treatment in the absence of safety data for maintenance treatment beyond 12 months.



If signs of a flare reoccur, twice daily treatment should be re-initiated (see flare treatment section above).



Elderly patients



Specific studies have not been conducted in elderly patients (see flare treatment section above).



Paediatric population



Children (2 years of age and above) should use the lower strength Protopic 0.03% ointment.



Protopic ointment should be applied once a day twice weekly (e.g. Monday and Thursday) to areas commonly affected by atopic dermatitis to prevent progression to flares. Between applications there should be 2–3 days without Protopic treatment.



The review of the child`s condition after 12 months treatment should include suspension of treatment to assess the need to continue this regimen and to evaluate the course of the disease.



Protopic ointment should not be used in children aged below 2 years until further data are available.



Method of administration



Protopic ointment should be applied as a thin layer to affected or commonly affected areas of the skin. Protopic ointment may be used on any part of the body, including face, neck and flexure areas, except on mucous membranes. Protopic ointment should not be applied under occlusion because this method of administration has not been studied in patients (see section 4.4).



4.3 Contraindications



Hypersensitivity to the active substance, macrolides in general, or to any of the excipients.



4.4 Special Warnings And Precautions For Use



Protopic should not be used in patients with congenital or acquired immunodeficiencies or in patients on therapy that cause immunosuppression.



The effect of treatment with Protopic ointment on the developing immune system of children aged below 2 years has not been established (see section 4.1).



Exposure of the skin to sunlight should be minimised and the use of ultraviolet (UV) light from a solarium, therapy with UVB or UVA in combination with psoralens (PUVA) should be avoided during use of Protopic ointment (see section 5.3). Physicians should advise patients on appropriate sun protection methods, such as minimisation of the time in the sun, use of a sunscreen product and covering of the skin with appropriate clothing. Protopic ointment should not be applied to lesions that are considered to be potentially malignant or pre-malignant.



Emollients should not be applied to the same area within 2 hours of applying Protopic ointment. Concomitant use of other topical preparations has not been assessed. There is no experience with concomitant use of systemic steroids or immunosuppressive agents.



Protopic ointment has not been evaluated for its efficacy and safety in the treatment of clinically infected atopic dermatitis. Before commencing treatment with Protopic ointment, clinical infections at treatment sites should be cleared. Patients with atopic dermatitis are predisposed to superficial skin infections. Treatment with Protopic may be associated with an increased risk of folliculitis and herpes viral infections (herpes simplex dermatitis [eczema herpeticum], herpes simplex [cold sores], Kaposi's varicelliform eruption) (see section 4.8). In the presence of these infections, the balance of risks and benefits associated with Protopic use should be evaluated.



The potential for local immunosuppression (possibly resulting in infections or cutaneous malignancies) in the long term (i.e. over a period of years) is unknown (see section 5.1).



Protopic contains the active substance tacrolimus, a calcineurin inhibitor. In transplant patients, prolonged systemic exposure to intense immunosuppression following systemic administration of calcineurin inhibitors has been associated with an increased risk of developing lymphomas and skin malignancies. In patients using tacrolimus ointment, cases of malignancies, including cutaneous and other types of lymphoma, and skin cancers have been reported (see section 4.8). Patients with atopic dermatitis treated with Protopic have not been found to have significant systemic tacrolimus levels.



Lymphadenopathy was uncommonly (0.8%) reported in clinical trials. The majority of these cases were related to infections (skin, respiratory tract, tooth) and resolved with appropriate antibiotic therapy. Transplant patients receiving immunosuppressive regimens (e.g. systemic tacrolimus) are at increased risk for developing lymphoma; therefore patients who receive Protopic and who develop lymphadenopathy should be monitored to ensure that the lymphadenopathy resolves. Lymphadenopathy present at initiation of therapy should be investigated and kept under review. In case of persistent lymphadenopathy, the aetiology of the lymphadenopathy should be investigated. In the absence of a clear aetiology for the lymphadenopathy or in the presence of acute infectious mononucleosis, discontinuation of Protopic should be considered.



Care should be taken to avoid contact with eyes and mucous membranes. If accidentally applied to these areas, the ointment should be thoroughly wiped off and/or rinsed off with water.



The use of Protopic ointment under occlusion has not been studied in patients. Occlusive dressings are not recommended.



As with any topical medicinal product, patients should wash their hands after application if the hands are not intended for treatment.



Tacrolimus is extensively metabolised in the liver and although blood concentrations are low following topical therapy, the ointment should be used with caution in patients with hepatic failure (see section 5.2).



The use of tacrolimus ointment is not recommended in patients with a skin barrier defect, such as Netherton's syndrome, lamellar ichthyosis, generalized erythroderma or cutaneous Graft Versus Host Disease. These skin conditions may increase systemic absorption of tacrolimus. Oral use of tacrolimus is also not recommended to treat these skin conditions. Post-marketing cases of increased tacrolimus blood level have been reported in these conditions.



Care should be exercised if applying Protopic to patients with extensive skin involvement over an extended period of time, especially in children (see section 4.2).



The development of any new change different from previous eczema within a treated area should be reviewed by the physician.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Formal topical drug interaction studies with tacrolimus ointment have not been conducted.



Tacrolimus is not metabolised in human skin, indicating that there is no potential for percutaneous interactions that could affect the metabolism of tacrolimus.



Systemically available tacrolimus is metabolised via the hepatic Cytochrome P450 3A4 (CYP3A4). Systemic exposure from topical application of tacrolimus ointment is low (<1.0 ng/ml) and is unlikely to be affected by concomitant use of substances known to be inhibitors of CYP3A4. However, the possibility of interactions cannot be ruled out and the concomitant systemic administration of known CYP3A4 inhibitors (e.g. erythromycin, itraconazole, ketoconazole and diltiazem) in patients with widespread and/or erythrodermic disease should be done with caution.



Paediatric population



An interaction study with protein-conjugated vaccine against Neisseria menigitidis serogroup C has been investigated in children aged 2-11 years. No effect on immediate response to vaccination, the generation of immune memory, or humoral and cell-mediated immunity has been observed (see section 5.1).



4.6 Pregnancy And Lactation



Fertility



There are no fertility data available.



Pregnancy



There are no adequate data from the use of tacrolimus ointment in pregnant women. Studies in animals have shown reproductive toxicity following systemic administration (see section 5.3). The potential risk for humans is unknown.



Protopic ointment should not be used during pregnancy unless clearly necessary.



Breastfeeding



Human data demonstrate that, after systemic administration, tacrolimus is excreted into breast milk. Although clinical data have shown that systemic exposure from application of tacrolimus ointment is low, breast-feeding during treatment with Protopic ointment is not recommended.



4.7 Effects On Ability To Drive And Use Machines



Protopic ointment is administered topically and is unlikely to have an effect on the ability to drive or use machines.



4.8 Undesirable Effects



In clinical studies approximately 50% of patients experienced some type of skin irritation adverse reaction at the site of application. Burning sensation and pruritus were very common, usually mild to moderate in severity and tended to resolve within one week of starting treatment. Erythema was a common skin irritation adverse reaction. Sensation of warmth, pain, paraesthesia and rash at the site of application were also commonly observed. Alcohol intolerance (facial flushing or skin irritation after consumption of an alcoholic beverage) was common.



Patients may be at an increased risk of folliculitis, acne and herpes viral infections.



Adverse reactions with suspected relationship to treatment are listed below by system organ class. Frequencies are defined as very common ( 1/10), common ( 1/100 to < 1/10) and uncommon (

Maintenance treatment



In a study of maintenance treatment (twice weekly treatment) in adults and children with moderate and severe atopic dermatitis the following adverse events were noted to occur more frequently than in the control group: application site impetigo (7.7% in children) and application site infections (6.4% in children and 6.3% in adults).



Post-marketing



Cases of malignancies, including cutaneous and other types of lymphoma, and skin cancers, have been reported in patients using tacrolimus ointment (see section 4.4).



Paediatric population



Frequency, type and severity of adverse reactions in children are similar to those reported in adults.



4.9 Overdose



Overdosage following topical administration is unlikely.



If ingested, general supportive measures may be appropriate. These may include monitoring of vital signs and observation of clinical status. Due to the nature of the ointment vehicle, induction of vomiting or gastric lavage is not recommended.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Other dermatologicals, ATC code: D11AH01



Mechanism of action and pharmacodynamic effects



The mechanism of action of tacrolimus in atopic dermatitis is not fully understood. While the following have been observed, the clinical significance of these observations in atopic dermatitis is not known.



Via its binding to a specific cytoplasmic immunophilin (FKBP12), tacrolimus inhibits calcium-dependent signal transduction pathways in T cells, thereby preventing the transcription and synthesis of IL-2, IL-3, IL-4, IL-5 and other cytokines such as GM-CSF, TNF-α and IFN-γ.



In vitro, in Langerhans cells isolated from normal human skin, tacrolimus reduced the stimulatory activity towards T cells. Tacrolimus has also been shown to inhibit the release of inflammatory mediators from skin mast cells, basophils and eosinophils.



In animals, tacrolimus ointment suppressed inflammatory reactions in experimental and spontaneous dermatitis models that resemble human atopic dermatitis. Tacrolimus ointment did not reduce skin thickness and did not cause skin atrophy in animals.



In patients with atopic dermatitis, improvement of skin lesions during treatment with tacrolimus ointment was associated with reduced Fc receptor expression on Langerhans cells and a reduction of their hyperstimulatory activity towards T cells. Tacrolimus ointment does not affect collagen synthesis in humans.



Clinical efficacy and safety



The efficacy and safety of Protopic was assessed in more than 18,500 patients treated with tacrolimus ointment in Phase I to Phase III clinical trials. Data from six major trials are presented here.



In a six-month multicentre double-blind randomised trial, 0.1% tacrolimus ointment was administered twice-a-day to adults with moderate to severe atopic dermatitis and compared to a topical corticosteroid based regimen (0.1% hydrocortisone butyrate on trunk and extremities, 1% hydrocortisone acetate on face and neck). The primary endpoint was the response rate at month 3 defined as the proportion of patients with at least 60% improvement in the mEASI (modified Eczema Area and Severity Index) between baseline and month 3. The response rate in the 0.1% tacrolimus group (71.6%) was significantly higher than that in the topical corticosteroid based treatment group (50.8%; p<0.001; Table 1). The response rates at month 6 were comparable to the 3-month results.

The incidence and nature of most adverse events were similar in the two treatment groups. Skin burning, herpes simplex, alcohol intolerance (facial flushing or skin sensitivity after alcohol intake), skin tingling, hyperaesthesia, acne and fungal dermatitis occurred more often in the tacrolimus treatment group. There were no clinically relevant changes in the laboratory values or vital signs in either treatment group throughout the study.



In the second trial, children aged from 2 to 15 years with moderate to severe atopic dermatitis received twice daily treatment for three weeks of 0.03% tacrolimus ointment, 0.1% tacrolimus ointment or 1% hydrocortisone acetate ointment. The primary endpoint was the area-under-the-curve (AUC) of the mEASI as a percentage of baseline averaged over the treatment period. The results of this multicentre, double-blind, randomised trial showed that tacrolimus ointment, 0.03% and 0.1%, is significantly more effective (p<0.001 for both) than 1% hydrocortisone acetate ointment (Table 2).

There were no clinically relevant changes in the laboratory values or vital signs in either treatment group throughout the clinical trial.



The purpose of the third multicentre, double-blind, randomised study was the assessment of efficacy and safety of 0.03% tacrolimus ointment applied once or twice a day relative to twice daily administration of 1% hydrocortisone acetate ointment in children with moderate to severe atopic dermatitis. Treatment duration was for up to three weeks.

The primary endpoint was defined as the percentage decrease in mEASI from the baseline to end of treatment. A statistically significant better improvement was shown for once daily and twice daily 0.03% tacrolimus ointment compared to twice daily hydrocortisone acetate ointment (p<0.001 for both). Twice daily treatment with 0.03% tacrolimus ointment was more effective than once daily administration (Table 3). The incidence of local skin burning was higher in the tacrolimus treatment groups than in the hydrocortisone group. There were no clinically relevant changes in the laboratory values or vital signs in either treatment group throughout the study.



In the fourth trial, approximately 800 patients (aged



The efficacy and safety of tacrolimus ointment in maintenance treatment of mild to severe atopic dermatitis was assessed in 524 patients in two Phase III multicentre clinical trials of similar design, one in adult patients (



The primary endpoint in both studies was the number of disease exacerbations requiring a “substantial therapeutic intervention” during the DCP, defined as an exacerbation with an IGA of 3-5 (i.e. moderate, severe and very severe disease) on the first day of the flare, and requiring more than 7 days treatment. Both studies showed significant benefit with twice weekly treatment with tacrolimus ointment with regard to the primary and key secondary endpoints over a period of 12 months in a pooled population of patients with mild to severe atopic dermatitis. In a subanalysis of a pooled population of patients with moderate to severe atopic dermatitis these differences remained statistically significant (Table 4). No adverse events not reported previously were observed in these studies.

A seven-month, double blind, randomised parallel group study of paediatric patients (2-11 years) with moderate to severe atopic dermatitis was performed. In one arm patients received Protopic 0.03% ointment (n=121) twice a day for 3 weeks and thereafter once a day until clearance. In the comparator arm patients received 1% hydrocortisone acetate ointment (HA) for head and neck and 0.1% hydrocortisone butyrate ointment for trunk and limbs (n=111) twice a day for 2 weeks and subsequently HA twice a day to all affected areas. During this period all patients and control subjects (n=44) received a primary immunisation and a rechallenge with a protein-conjugate vaccine against Neisseria menigitidis serogroup C.



The primary endpoint of this study was the response rate to vaccination, defined as the percentage of patients with a serum bactericidal antibody (SBA) titre



The primary response to vaccination was not affected.



5.2 Pharmacokinetic Properties



Clinical data have shown that tacrolimus concentrations in systemic circulation after topical administration are low and, when measurable, transient.



Absorption



Data from healthy human subjects indicate that there is little or no systemic exposure to tacrolimus following single or repeated topical application of tacrolimus ointment.



Most atopic dermatitis patients (adults and children) treated with single or repeated application of tacrolimus ointment (0.03-0.1%), and infants from age of 5 months treated with tacrolimus ointment (0.03%) had blood concentrations < 1.0 ng/ml. When observed, blood concentrations exceeding 1.0 ng/ml were transient. Systemic exposure increases with increasing treatment areas. However, both the extent and the rate of topical absorption of tacrolimus decrease as the skin heals. In both adults and children with an average of 50% body surface area treated, systemic exposure (i.e. AUC) of tacrolimus from Protopic is approximately 30-fold less than that seen with oral immunosuppressive doses in kidney and liver transplant patients. The lowest tacrolimus blood concentration at which systemic effects can be observed is not known.



There was no evidence of systemic accumulation of tacrolimus in patients (adults and children) treated for prolonged periods (up to one year) with tacrolimus ointment.



Distribution



As systemic exposure is low with tacrolimus ointment, the high binding of tacrolimus (> 98.8%) to plasma proteins is considered not to be clinically relevant.



Following topical application of tacrolimus ointment, tacrolimus is selectively delivered to the skin with minimal diffusion into the systemic circulation.



Metabolism



Metabolism of tacrolimus by human skin was not detectable. Systemically available tacrolimus is extensively metabolised in the liver via CYP3A4.



Elimination



When administered intravenously, tacrolimus has been shown to have a low clearance rate. The average total body clearance is approximately 2.25 l/h. The hepatic clearance of systemically available tacrolimus could be reduced in subjects with severe hepatic impairment, or in subjects who are co-treated with drugs that are potent inhibitors of CYP3A4.



Following repeated topical application of the ointment the average half-life of tacrolimus was estimated to be 75 hours for adults and 65 hours for children.



Paediatric population



The pharmacokinetics of tacrolimus after topical application are similar to those reported in adults, with minimal systemic exposure and no evidence of accumulation (see above).



5.3 Preclinical Safety Data



Repeated dose toxicity and local tolerance



Repeated topical administration of tacrolimus ointment or the ointment vehicle to rats, rabbits and micropigs was associated with slight dermal changes such as erythema, oedema and papules.



Long-term topical treatment of rats with tacrolimus led to systemic toxicity including alterations of kidneys, pancreas, eyes and nervous system. The changes were caused by high systemic exposure of rodents resulting from high transdermal absorption of tacrolimus. Slightly lower body weight gain in females was the only systemic change observed in micropigs at high ointment concentrations (3%).



Rabbits were shown to be especially sensitive to intravenous administration of tacrolimus, reversible cardiotoxic effects being observed.



Mutagenicity



In vitro and in vivo tests did not indicate a genotoxic potential of tacrolimus.



Carcinogenicity



Systemic carcinogenicity studies in mice (18 months) and rats (24 months) revealed no carcinogenic potential of tacrolimus.



In a 24-month dermal carcinogenicity study performed in mice with 0.1% ointment, no skin tumours were observed. In the same study an increased incidence of lymphoma was detected in association with high systemic exposure.



In a photocarcinogenicity study, albino hairless mice were chronically treated with tacrolimus ointment and UV radiation. Animals treated with tacrolimus ointment showed a statistically significant reduction in time to skin tumour (squamous cell carcinoma) development and an increase in the number of tumours. It is unclear whether the effect of tacrolimus is due to systemic immunosuppression or a local effect. The risk for humans cannot be completely ruled out as the potential for local immunosuppression with the long-term use of tacrolimus ointment is unknown.



Reproduction toxicity



Embryo/foetal toxicity was observed in rats and rabbits, but only at doses that caused significant toxicity in maternal animals. Reduced sperm function was noted in male rats at high subcutaneous doses of tacrolimus.
