Dutasteride is a synthetic 4-azasteroid compound that is a selective inhibitor of both the type 1 and type 2 isoforms of steroid 5 alpha-reductase, an intracellular enzyme that converts testosterone to DHT. Dutasteride is chemically designated as (5α,17β)-N-{2,5 bis(trifluoromethyl)phenyl}-3-oxo-4-azaandrost-1-ene-17-carboxamide. The molecular formula of dutasteride is C 27 H 30 F 6 N 2 O 2 , representing a molecular weight of 528.5 with the following structural formula: Dutasteride USP is a white to pale yellow powder with a melting point of 242 ° to 250 ° C. It is soluble in ethanol (44 mg/mL), methanol (64 mg/mL), and polyethylene glycol 400 (3 mg/mL), but it is insoluble in water. Each dutasteride capsule, administered orally, contains 0.5 mg of dutasteride USP dissolved in a mixture of mono-di-glycerides of caprylic/capric acid and butylated hydroxytoluene. The inactive excipients in the capsule shell are gelatin (from certified BSE-free bovine sources), glycerin, medium chain triglycerides, opatint white (contains glycerin and titanium dioxide), opatint yellow (contains ferric oxide yellow and glycerin), and soy lecithin. The soft gelatin capsules are printed with edible red ink, opacode red. The printing ink contains ferric oxide red, isopropyl alcohol, propylene glycol, and simethicone. CHEMICAL STRUCTURE
