USPTO Abstract

Pharmaceutical formulations and methods for the topical or transdermal delivery of 1isobutyl-1H-imidazo[4,5-c]-quinolin-4-amine or 1-(2-methylpropyl)-1H- imidazo[4,5-c] quinolin-4-amine, i.e., imiquimod, to treat genital warts with shorter durations of therapy than currently prescribed for the commercially available Aldara® 5% imiquimod cream, as now approved by the U.S. Food & Drug Administration ("FDA"), are disclosed and described. More specifically, lower dosage strength imiquimod formulations to deliver an efficacious dose of imiquimod for treating genital warts with an acceptable safety profile and dosing regimens that are shorter and more convenient for patient use than the dosing regimen currently approved by the U.S. Food & Drug Administration ("FDA") for Aldara® 5% imiquimod cream to treat genital warts are also disclosed and described.
