Bunazosin（Cat No.:I043944）is an alpha-1 adrenergic antagonist used primarily to treat hypertension and benign prostatic hyperplasia (BPH). By blocking alpha-1 receptors in vascular smooth muscle, it helps relax blood vessels, reducing blood pressure. Additionally, it can alleviate BPH symptoms by relaxing the muscles in the prostate and bladder neck, improving urinary flow. Bunazosin is typically administered orally and is considered effective in managing these conditions. Its use may be associated with side effects like dizziness or orthostatic hypotension, especially when starting treatment or adjusting dosages.
