Product Elements:
Condylox podofilox podofilox podofilox alcohol glycerin lactic acid, unspecified form hydroxypropyl cellulose (1600000 wamw) sodium lactate butylated hydroxytoluene
Indications and Usage:
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. squamous cell carcinoma may also be associated with human papillomavirus which should not be treated with condylox gel 0.5%.
Warnings:
Warnings correct diagnosis of the lesions to be treated is essential. see the diagnosis subsection of the indications and usage section. condylox gel 0.5% is intended for cutaneous use only. avoid contact with the eyes. if contact with the eyes occurs, patients should immediately flush the eyes with copious quantities of water and seek medical advice. drug product is flammable. keep away f rom open flame.
General Precautions:
General data are not available on the safe and effective use of this product for treatment of warts occurring on mucous membranes of the genital area (including the urethra, rectum and vagina). the recommended method of application, frequency of application, and duration of usage should not be exceeded (see dosage and administration ).
Dosage and Administration:
Dosage and administration the prescriber should ensure that the patient is fully aware of the correct method of therapy and identify which specific warts should be treated. apply twice daily for 3 consecutive days, then discontinue for 4 consecutive days. this one-week cycle of treatment may be repeated until there is no visible wart tissue or for a maximum of four cycles. if there is incomplete response after four treatment cycles, discontinue treatment and consider alternative treatment. safety and effectiveness of more than four treatment cycles has not been established. there is no evidence to suggest that more frequent application will increase efficacy, but additional applications would be expected to increase the rate of local adverse reactions and systemic absorption. condylox gel 0.5% should be applied to the warts with the applicator tip or finger. application on the surrounding normal tissue should be minimized. treatment should be limited to 10 cm 2 or less of wart tissue a

Contraindications:
Contraindications condylox gel 0.5% is contraindicated for patients who develop hypersensitivity or intolerance to any components of the formulation.

Use in Pregnancy:
Pregnancy 0.5% podofilox solution was not teratogenic in the rabbit following topical application of up to 0.21 mg/kg (2.85 mg/m 2 , approximately 2 times the maximum human dose) once daily for 13 days. the scientific literature contains references that podofilox is embryotoxic in rats when administered intraperitoneally at a dose of 5 mg/kg (29.5 mg/m 2 , approximately 19 times the recommended maximum human dose.) 9 teratogenicity and embryotoxicity have not been studied with intravaginal application. many antimitotic drug products are known to be embryotoxic. there are no adequate and well-controlled studies in pregnant women. condylox gel 0.5% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Pediatric Use:
Pediatric use safety and effectiveness in pediatric patients have not been established.
Overdosage:
Overdosage topically applied podofilox may be absorbed systemically (see clinical pharmacology section). toxicity reported following systemic administration of podofilox in investigational use for cancer treatment included: nausea, vomiting, fever, diarrhea, bone marrow depression, and oral ulcers. following 5 to 10 daily intravenous doses of 0.5 to 1 mg/kg/day, significant hematological toxicity occurred but was reversible. 10 other toxicities occurred at lower doses. toxicity reported following systemic administration of podophyllum resin included: nausea, vomiting, fever, diarrhea, peripheral neuropathy, altered mental status, lethargy, coma, tachypnea, respiratory failure, leukocytosis, pancytosis, hematuria, renal failure and seizures. 11 treatment of topical overdosage should include washing the skin free of any remaining drug and symptomatic and supportive therapy.
Description:
Description podofilox is an antimitotic drug which can be chemically synthesized or purified from the plant families coniferae and berberidaceae (e.g. species of juniperus and podophyllum). condylox gel 0.5% is formulated for topical administration. each gram of gel contains 5 mg of podofilox in a buffered alcoholic gel containing alcohol, glycerin, lactic acid, hydroxypropyl cellulose, sodium lactate, and butylated hydroxytoluene. podofilox has a molecular weight of 414.4 daltons, and is soluble in alcohol and sparingly soluble in water. its chemical name is [5r,-(5α, 5aβ, 8aα, 9α]-5,8,8a,9-tetrahydro-9-hydroxy-5-(3,4,5-trimethoxyphenyl) furo[3',4':6,7]naphtho-[2,3,-d]-1,3-dioxol-6(5ah)-one. podofilox has the following structural formula: structural formula
Clinical Pharmacology:
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 .

Carcinogenesis and Mutagenesis and Impairment of Fertility:
Carcinogenesis, mutagenesis and impairment of fertility an 80-week carcinogenicity study in the mouse was performed using a 0.5% podofilox solution applied dermally at 0.04, 0.2 and 1.0 mg/kg/day. there were no differences between the podofilox treated mice at any dose level and vehicle control in the incidence of neoplasia. published animal studies, in general, have not shown the drug substance, podofilox, to be carcinogenic. 2,3,4,5,6 there are published reports that, in mouse studies, crude podophyllin resin (containing podofilox) applied topically to the cervix produced changes resembling carcinoma in situ. 7 these changes were reversible at five weeks after cessation of treatment. in one reported experiment, epidermal carcinoma of the vagina and cervix was found in 1 out of 18 mice after 120 applications of podophyllin 8 (the drug was applied twice weekly over a 15-month period). podofilox was not mutagenic in the ames plate reverse mutation assay at concentrations up to 5 mg/plat

Clinical Studies:
Clinical studies in the first multicenter clinical study in 326 patients with anogenital warts, condylox gel 0.5% and its vehicle were applied in a double-blind fashion to comparable patient groups. of the 260 patients with efficacy data, 176 were treated with condylox gel 0.5%. patients applied condylox gel 0.5% twice daily for three consecutive days followed by a 4 day ârestâ period. at the end of 4 weeks, 38.4% of the patients had complete clearing of the wart tissue when treated with condylox gel 0.5%. in the second multicenter clinical trial in 108 evaluable patients with anogenital warts, condylox (podofilox) topical solution 0.5% was compared with condylox gel 0.5% for efficacy. as in the first clinical trial, patients applied condylox gel 0.5% twice daily for three consecutive days followed by a four day ârestâ period. similar clearance rates were observed. at the end of 4 weeks, 25.6% of the patients had complete clearing of the wart tissue when treated wit
