Used primarily to treat symptoms of benign prostatic hyperplasia (BPH), silodosin helps improve urine flow by relaxing the muscles in the prostate and bladder neck. It selectively targets alpha-1A adrenergic receptors, which are involved in prostate smooth muscle contraction. This action reduces urinary hesitancy, weak stream, and frequent or urgent need to urinate, especially at night. Due to its high selectivity, it has a lower impact on blood pressure compared to other similar medications, making it a suitable option for patients concerned about cardiovascular side effects.
