Hytrin is an antihypertensive. Hytrin works by relaxing the blood vessels. Hytrin is prescribed to treat benign prostatic hyperplasia (BPH) in men and to treat high blood pressure in both men and women.
Hytrin is prescribed in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH), which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency. It also is prescribed alone or in combination with other medications to treat high blood pressure.
Hytrin is in a class of drugs called alpha-blockers.
Hytrin lowers blood pressure by relaxing the blood vessels so that blood can flow more easily through the body.
Hytrin relieves the symptoms of BPH by relaxing the muscles of the bladder and prostate.
