2.5mg Prazosin Tablets IP contains the active ingredient prazosin hydrochloride. This works by relaxing the muscles in the walls of blood vessels and the prostate gland. The relaxation helps to widen the blood vessels, allowing blood to flow more easily, which in turn lowers blood pressure. It is a medication classified as an alpha-blocker, primarily used to treat high blood pressure (hypertension) and certain urinary symptoms associated with an enlarged prostate gland (benign prostatic hyperplasia or BPH). 2.5mg Prazosin Tablets IP can help relieve urinary symptoms such as difficulty urinating, frequent urination, and a weak urine stream by relaxing the muscles in the prostate and bladder neck.
