TACROLIMUS

Tacrolimus ointment contains tacrolimus, a macrolide immunosuppressant produced by Streptomyces tsukubaensis . It is for topical dermatologic use only. Chemically, tacrolimus is designated as [3 S -[3 R *[ E (1 S *,3 S *,4 S *)],4 S *,5 R *,8 S *,9 E ,12 R *,14 R *,15 S *,16 R *,18 S *,19 S *, 26a R *]]-5,6,8,11,12,13,14,15,16,17,18,19,24,25,26,26a-hexadecahydro-5,19-dihydroxy-3-[2-(4-hydroxy-3- methoxycyclohexyl)-1-methylethenyl]-14,16-dimethoxy-4,10,12,18-tetramethyl-8-(2-propenyl)-15,19- epoxy-3H-pyrido[2,1- c ][1,4] oxaazacyclotricosine-1,7,20,21(4H,23H)-tetrone, monohydrate. It has the following structural formula: Tacrolimus has an empirical formula of C 44 H 69 NO 12 •H 2 O and a formula weight of 822.03. Each gram of tacrolimus ointment contains (w/w) 0.1% of tacrolimus in a base of mineral oil, paraffin, propylene carbonate, white petrolatum, and white wax. structute tacrolimus

Tacrolimus ointment, both 0.03% and 0.1% for adults, and only 0.03% for children aged 2 to 15 years, is indicated as second-line therapy for the short-term and non-continuous chronic treatment of moderate to severe atopic dermatitis in non-immunocompromised adults and children who have failed to respond adequately to other topical prescription treatments for atopic dermatitis, or when those treatments are not advisable. Tacrolimus ointment is not indicated for children younger than 2 years of age (see boxed WARNING , WARNINGS and PRECAUTIONS : Pediatric Use ).

ADULT Tacrolimus ointment 0.1% Apply a thin layer of tacrolimus ointment to the affected skin twice daily. The minimum amount should be rubbed in gently and completely to control signs and symptoms of atopic dermatitis. Stop using when signs and symptoms of atopic dermatitis resolve. If signs and symptoms (e.g. itch, rash, and redness) do not improve within 6 weeks, patients should be re-examined by their healthcare provider to confirm the diagnosis of atopic dermatitis. Continuous long-term use of topical calcineurin inhibitors, including tacrolimus ointment should be avoided, and application should be limited to areas of involvement with atopic dermatitis. The safety of tacrolimus ointment under occlusion, which may promote systemic exposure, has not been evaluated. Tacrolimus ointment should not be used with occlusive dressings.

Tacrolimus ointment is contraindicated in patients with a history of hypersensitivity to tacrolimus or any other component of the ointment.

No phototoxicity and no photoallergenicity were detected in clinical studies with 12 and 216 normal volunteers, respectively. One out of 198 normal volunteers showed evidence of sensitization in a contact sensitization study. In three 12 week randomized vehicle-controlled studies and four safety studies, 655 and 9,163 patients respectively, were treated with tacrolimus ointment. The duration of follow-up for adult and pediatric patients in the safety studies is tabulated below.

The table also depicts the unadjusted incidence of adverse events in four safety studies, regardless of relationship to study drug.

Other adverse events which occurred at an incidence between 0.2% and less than 1% in clinical studies in the above table include: abnormal vision, abscess, anaphylactoid reaction, anemia, anorexia, anxiety, arthritis, arthrosis, bilirubinemia, blepharitis, bone disorder, breast neoplasm benign, bursitis, cataract NOS, chest pain, chills, colitis, conjunctival edema, constipation, cramps, cutaneous moniliasis, cystitis, dehydration, dizziness, dry eyes, dry mouth/nose, dyspnea, ear disorder, ecchymosis, edema, epistaxis, eye pain, furunculosis, gastritis, gastrointestinal disorder, hernia, hypercholesterolemia, hypertonia, hypothyroidism, joint disorder, laryngitis, leukoderma, lung disorder, malaise, migraine, moniliasis, mouth ulceration, nail disorder, neck pain, neoplasm benign, oral moniliasis, otitis externa, photosensitivity reaction, rectal disorder, seborrhea, skin carcinoma, skin discoloration, skin hypertrophy, skin ulcer, stomatitis, tendon disorder, thinking abnormal, tooth caries, sweating, syncope, tachycardia, taste perversion, unintended pregnancy, vaginal moniliasis, vaginitis, valvular heart disease, vasodilatation, and vertigo. Post-Marketing Events The following adverse reactions have been identified during postapproval use of tacrolimus ointment. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. CNS Seizures Neoplasms Lymphomas, basal cell carcinoma, squamous cell carcinoma, malignant melanoma Infections Bullous impetigo, osteomyelitis, septicemia Renal Acute renal failure in patients with or without Netherton’s syndrome, renal impairment Skin Rosacea, application site edema

Formal topical drug interaction studies with tacrolimus ointment have not been conducted. Based on its extent of absorption, interactions of tacrolimus ointment with systemically administered drugs are unlikely to occur but cannot be ruled out (see CLINICAL PHARMACOLOGY ). The concomitant administration of known CYP3A4 inhibitors in patients with widespread and/or erythrodermic disease should be done with caution. Some examples of such drugs are erythromycin, itraconazole, ketoconazole, fluconazole, calcium channel blockers and cimetidine.
