Dutasteride and tamsulosin hydrochloride is not indicated for use in females. Dutasteride, a component of dutasteride and tamsulosin hydrochloride, is a 5-alpha-reductase inhibitor that prevents conversion of testosterone to dihydrotestosterone (DHT), a hormone necessary for normal development of male genitalia.

Wirkmechanismus

Dutasteride and tamsulosin hydrochloride are a combination of 2 drugs with different mechanisms of action to improve symptoms in patients with BPH: dutasteride, a 5-alpha-reductase inhibitor, and tamsulosin, an antagonist of alpha 1A -adrenoreceptors. Dutasteride Dutasteride inhibits the conversion of testosterone to DHT. DHT is the androgen primarily responsible for the initial development and subsequent enlargement of the prostate gland.
