Used in the treatment of hypertension due to its potent vasodilatory effects. Acts as a selective alpha-1 adrenergic receptor antagonist, helping to relax smooth muscle in blood vessels, thereby reducing peripheral resistance and lowering blood pressure. Commonly prescribed for patients with essential hypertension, especially those who do not respond adequately to first-line therapies. Also investigated for use in benign prostatic hyperplasia (BPH) due to its ability to relax smooth muscle in the prostate and bladder neck, improving urinary flow. Its dual application in cardiovascular and urological conditions makes it valuable in managing patients with coexisting hypertension and BPH.
