Mechanism of Action
CLINICAL PHARMACOLOGY Mechanism of Action Treatment of anogenital warts with podofilox results in necrosis of visible wart tissue. The exact mechanism of action is unknown. Pharmacokinetics In systemic absorption studies in 52 patients, topical application of 0.05 mL of an ethanolic solution containing 0.5% podofilox to external genitalia did not result in detectable serum levels. Applications of 0.1 to 1.5 mL resulted in peak serum levels of 1 to 17 ng/mL one to two hours after application. The elimination half-life ranged from 1.0 to 4.5 hours. The drug was not found to accumulate after multiple treatments 1 .
Indications
- INDICATIONS AND USAGE Condylox Gel 0.5% is indicated for the topical treatment of anogenital warts (external genital warts and perianal warts). This product is not indicated in the treatment of mucous membrane warts (see PRECAUTIONS ). Diagnosis Although anogenital warts have a characteristic appearance, histopathologic confirmation should be obtained if there is any doubt of the diagnosis. Differentiating warts from squamous cell carcinoma and "Bowenoid papulosis" is of particular concern.
