No, Urimax D is not a steroid. It has two main active ingredients - tamsulosin hydrochloride and dutasteride. Tamsulosin hydrochloride, a selective alpha 1A-adrenoceptor blocking drug, shows selectivity for alpha 1A-receptors. Dutasteride is a synthetic 4-azasteroid molecule that inhibits steroid five alpha-reductase types I and type II isoforms, an intracellular enzyme that transforms testosterone to 5 alpha-dihydrotestosterone (DHT)
