Contraindications oxistat lotion is contraindicated in individuals who have shown hypersensitivity to any of their components.

Adverse reactions in a controlled, multicenter clinical trial of 269 patients treated with oxiconazole nitrate lotion , 1%, 7 (2.6%) reported adverse reactions thought to be related to drug therapy. these reactions included burning and stinging (0.7% each) and pruritus, scaling, tingling, pain, and dyshidrotic eczema (0.4% each). the following additional adverse experiences have been reported with the topical use of oxiconazole nitrate: irritation and allergic contact dermatitis, folliculitis, erythema, papules, fissure, maceration, rash, and nodules. to report suspected adverse reactions, contact ani pharmaceuticals, inc. at 1-800-308-6755 or fda at 1-800-fda-1088 or www.fda.gov/medwatch.

Drug interactions potential drug interactions between oxistat and other drugs have not been systematically evaluated.

Pregnancy teratogenic effects reproduction studies have been performed in rabbits, rats, and mice at oral doses up to 100, 150, and 200 mg/kg/day (57, 40, and 27 times the human dose based on mg/m 2 ), respectively, and revealed no evidence of harm to the fetus due to oxiconazole nitrate. 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.

Pediatric use safety and effectiveness in pediatric patients have not been established.

Geriatric use a limited number of patients at or above 60 years of age (n ~ 396) have been treated with oxiconazole nitrate cream in us and non-us clinical trials, and a limited number (n = 43) have been treated with oxistat lotion in us clinical trials. the number of patients is too small to permit separate analysis of efficacy and safety. no adverse events were reported with oxistat lotion in geriatric patients, and the adverse reactions reported with oxiconazole nitrate cream in this population were similar to those reported by younger patients. based on available data, no adjustment of dosage of oxistat lotion in geriatric patients is warranted.

Overdosage when 5% oxiconazole cream (5 times the concentration of the marketed product) was applied at a rate of 1 g/kg to approximately 10% of body surface area of a group of 40 male and female rats for 35 days, 3 deaths and severe dermal inflammation were reported. no overdoses in humans have been reported with use of oxiconazole nitrate cream or lotion.

Description oxistat ® (oxiconazole nitrate) lotion, 1% contains the antifungal active compound oxiconazole nitrate. this formulation is for topical dermatologic use only. chemically, oxiconazole nitrate is 2',4'-dichloro-2-imidazol-1-ylacetophenone ( z )-[ 0 -(2,4-dichlorobenzyl)oxime], mononitrate. the compound has the molecular formula c 18 h 13 on 3 cl 4 ·hno 3 , a molecular weight of 492.15, and the following structural formula: oxiconazole nitrate is a nearly white crystalline powder, soluble in methanol; sparingly soluble in ethanol, chloroform, and acetone; and very slightly soluble in water. oxistat lotion contains 10 mg of oxiconazole per gram of lotion in a white to off-white, opaque lotion base of purified water, white petrolatum, stearyl alcohol, propylene glycol, polysorbate 60, cetyl alcohol, and benzoic acid 0.2% as a preservative. structure

Clinical pharmacology pharmacokinetics the penetration of oxiconazole nitrate into different layers of the skin was assessed using an in vitro permeation technique with human skin. five hours after application of 2.5 mg/cm 2 of oxiconazole nitrate cream onto human skin, the concentration of oxiconazole nitrate was demonstrated to be 16.2 μmol in the epidermis, 3.64 μmol in the upper corium, and 1.29 μmol in the deeper corium. systemic absorption of oxiconazole nitrate is low. using radiolabeled drug, less than 0.3% of the applied dose of oxiconazole nitrate was recovered in the urine of volunteer subjects up to 5 days after application of the cream formulation. neither in vitro nor in vivo studies have been conducted to establish relative activity between the lotion and cream formulations. microbiology oxiconazole nitrate is an imidazole derivative whose antifungal activity is derived primarily from the inhibition of ergosterol biosynthesis, which is critical for cellular memb Read more...

Carcinogenesis, mutagenesis, impairment of fertility although no long-term studies in animals have been performed to evaluate carcinogenic potential, no evidence of mutagenic effect was found in 2 mutation assays (ames test and chinese hamster v79 in vitro cell mutation assay) or in 2 cytogenetic assays (human peripheral blood lymphocyte in vitro chromosome aberration assay and in vivo micronucleus assay in mice). reproductive studies revealed no impairment of fertility in rats at oral doses of 3 mg/kg/day in females (1 time the human dose based on mg/m 2 ) and 15 mg/kg/day in males (4 times the human dose based on mg/m 2 ). however, at doses above this level, the following effects were observed: a reduction in the fertility parameters of males and females, a reduction in the number of sperm in vaginal smears, extended estrous cycle, and a decrease in mating frequency.

Clinical studies the following definitions were applied to the clinical and microbiological outcomes in patients enrolled in the clinical trial that form the basis for the approval of oxistat lotion. definitions 1. mycological cure: no evidence (culture and koh preparation) of the baseline (original) pathogen in a specimen from the affected area taken at the 2-week post-treatment visit (for tinea [pityriasis] versicolor, mycological cure was limited to koh only). 2. treatment success: both a global evaluation of 90% clinical improvement and a microbiologic eradication (see above) at the 2-week post-treatment visit. tinea pedis the clinical trial for the lotion formulation line extension involved 332 evaluable patients with clinically and microbiologically established tinea pedis. of these evaluable patients, 64% were diagnosed with hyperkeratotic plantar tinea pedis and 28% with interdigital tinea pedis. seventy-seven percent (77%) had disease secondary to infection with trichophyton r Read more...
