Used primarily to treat high blood pressure (hypertension) and symptoms of benign prostatic hyperplasia (BPH), which is an enlarged prostate. It works by relaxing blood vessels so blood can flow more easily, reducing the workload on the heart. For men with BPH, it helps improve urine flow by relaxing the muscles in the prostate and bladder neck. This dual action makes it beneficial for patients who have both hypertension and prostate issues. It is taken orally, usually once daily, and is part of long-term management rather than for immediate relief of symptoms.
