ECONAZOLE NITRATE

Econazole nitrate topical foam, 1% contains the azole antifungal agent, econazole nitrate in an oil-in-water emulsion base consisting of the following inactive ingredients: dimethicone, glycerin, polysorbate 20, povidone, propylene glycol, stearic acid, trolamine, purified water and butane as a propellant. Each gram of econazole nitrate topical foam, 1% contains 10 mg of econazole nitrate, USP, in a white to off-white foam. Econazola nitrate topical foam, 1% is alcohol (ethanol)-free and for topical use only. Chemically, econazole nitrate is 1-[2-{(4-chloro-phenyl)methoxy}-2-(2,4-dichlorophenyl) ethyl]-1H-imidazole mononitrate. Econazole nitrate has the molecular formula C 18 H 15 Cl 3 N 2 O. HNO 3 and a molecular weight of 444.70. Its molecular structure is as follows: Chemical Structure

- During clinical trials with econazole nitrate topical foam, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the econazole nitrate and vehicle arms. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Trifluent Pharma at 1-800-927-5191 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling. Revised: 09/2025 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In two double-blind, vehicle-controlled clinical trials, 495 subjects were exposed to econazole nitrate topical foam or vehicle (246 subjects were exposed to econazole nitrate topical foam, 1% and 249 were exposed to vehicle). Subjects with interdigital tinea pedis applied foam or vehicle once daily for approximately 28 days. During clinical trials with econazole nitrate topical foam, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the econazole nitrate and vehicle arms.

- 7.1 Warfarin Concomitant administration of econazole and warfarin has resulted in enhancement of anticoagulant effect. Most cases reported product application with use under occlusion, genital application, or application to a large body surface area which may increase the systemic absorption of econazole nitrate. Monitoring of International Normalized Ratio (INR) and/or prothrombin time may be indicated especially for patients who apply econazole to large body surface areas, in the genital area, or under occlusion.

Store at controlled room temperature 20°C to 25°C (68°F to 77°F) with excursions permitted between 15°C and 30°C (59°F and 86°F). Do not refrigerate or freeze.
