How DUTASTERIDE AND TAMSULOSIN HYDROCHLORIDE Works

This medication utilizes two distinct mechanisms of action: dutasteride is a competitive, specific inhibitor of both type 1 and type 2 5-alpha-reductase isoenzymes, which blocks the conversion of testosterone to dihydrotestosterone (DHT), the primary androgen responsible for prostate enlargement. Tamsulosin is an antagonist of alpha-1A adrenoreceptors located in the prostate and bladder neck; blockade of these receptors relaxes smooth muscle tone, thereby improving urine flow rate and reducing the obstructive and irritative symptoms of BPH.
