Used primarily to treat high blood pressure (hypertension) and symptoms of benign prostatic hyperplasia (BPH) in men. It works by relaxing blood vessels, allowing blood to flow more easily, which helps lower blood pressure. In BPH, it relaxes muscles in the prostate and bladder neck, improving urine flow and reducing difficulty in urination. Often prescribed as a long-term management option for these conditions, it can reduce the risk of heart-related complications due to hypertension.
