Hytrin is used for high blood pressure treatment and signs and symptoms of benign prostatic hyperplasia (BPH). Hytrin is an alpha-blocker. It works by relaxing the muscles of blood vessels which leads to lower blood pressure. In BPH alpha-blockers relax the muscles round the urethra (the tube that drains urine from the bladder) which improves urinary symptoms.
Take the medicine exactly as prescribed. The medicine is to be taken at the same time each day. Take the first dose at bed time to minimize the chances of getting dizzy or faint. The tablets can be taken with milk or food to avoid stomach disorder. It is important to continue taking the medicine even if there are signs of recuperation. Most people with high blood pressure do not feel sick. Do not discontinue the treatment without consulting the doctor.
The Mechanism of Action
Hytrin belongs to a class of drugs called alpha-1 blockers, which relax the smooth muscles of arteries, prostate and bladder neck. Other alpha blockers in the same class of drugs include doxazosin (Cardura), alfuzosin (Uroxatral), tamsulosin (Flomax) and prazosin (MINIPRESS). Relaxing the smooth muscles of the arteries lowers blood pressure. Relaxing the smooth muscles around the bladder neck relieves urinary obstruction caused by enlarged prostate (prostatic hypertrophy).
