Finax 1 (Finasteride 1mg) GPO
Size: 30 tablets
Active ingredient: Finasteride 1mg, which is a type of medicine known as a 5-alpha reductase inhibitor. Finasteride works by preventing the action of a chemical in the body called 5-alpha reductase.
5-alpha reductase is an enzyme that converts the male hormone testosterone into a more active form called dihydrotestosterone (DHT). By blocking its action, finasteride prevents this activation of testosterone.
Enlargement of the prostate gland (benign prostatic hyperplasia), which often occurs in men with advancing age, is dependent upon testosterone being converted to DHT within the prostate gland. In the absence of DHT the prostate shrinks. By decreasing the amount of DHT, finasteride helps shrink the prostate.
The prostate gland is found only in men and lies at the top of the tube connecting the bladder to the outside (urethra). Enlargement of the prostate causes it to press on the urethra and bladder and can cause urinary symptoms such as difficulty passing urine and an increased need to urinate, particularly at night. By shrinking the prostate, finasteride relieves the pressure on the bladder and urethra. This allows urine to flow freely past the prostate and relieves the urinary symptoms associated with this condition.
