Which medication is specifically indicated for the treatment of hypertension and prostate symptoms?

Terazosin is specifically indicated for the treatment of both hypertension and symptoms associated with benign prostatic hyperplasia (BPH). It belongs to a class of medications known as alpha-1 adrenergic antagonists. By blocking alpha-1 receptors, terazosin induces vasodilation, which helps lower blood pressure. Additionally, it relaxes the smooth muscle in the prostate and bladder neck, improving urinary flow and alleviating symptoms of BPH such as difficulty in urination.

In the context of other medications mentioned, propranolol and atenolol are beta-blockers primarily used for hypertension, and while they can help with certain cardiovascular conditions, they do not address prostate symptoms. Doxazosin, much like terazosin, is also an alpha-1 blocker used for hypertension and prostate symptoms; however, the question specifically highlights terazosin. Thus, terazosin stands out for having a well-established dual indication for treating both hypertension and BPH symptoms, making it the best answer in this context.
