Pharmacology (Source, Chemical and Physical Composition) Of Wonica 0.139

Eflornithine prevents hair growth by inhibiting the anagen phase of hair production. This occurs by eflornithine irreversibly binding (also called suicide inhibition) to ornithine decarboxylase (ODC) and physically preventing the natural substrate ornithine from accessing the active site.

Dosage And Administration of Wonica 0.139

Eflornithine cream should be applied to the affected area twice daily, at least eight hours apart. Efficacy has only been demonstrated for affected areas of the face and under the chin. The application should be limited to these areas. Maximal applied doses used safely in clinical trials were up to 30 grams per month. Improvement in the condition may be noticed within eight weeks of starting treatment. Continued treatment may result in further improvement and is necessary to maintain beneficial effects. The condition may return to pre-treatment levels within eight weeks following discontinuation of treatment. Use should be discontinued if no beneficial effects are noticed within four months of commencing therapy. Patients may need to continue to use a hair removal method (e.g. shaving or plucking) in conjunction with Eflornithine cream. In that case, the cream should be applied no sooner than five minutes after shaving or use of other hair removal methods, as increased stinging or burning may otherwise occur.Elderly: (>65 years) No dosage adjustment is necessary.Pediatric population: The safety and efficacy of Eflornithine in children aged 0 to 18 years has not been established. There is no data available to support use in this age group.Hepatic/renal impairment: The safety and efficacy of Eflornithine in women with hepatic or renal impairment have not been established. As the safety of Eflornithine has not been studied in patients with severe renal impairment, caution should be used when prescribing Eflornithine cream for these patients. A thin layer of the cream should be applied to clean and dry affected areas. The cream should be rubbed in thoroughly. The medicinal product should be applied such that no visual residual product remains on the treated areas after rub-in. Hands should be washed after applying this medicinal product.
