Terazosin Hydrochloride: A Long Acting α1-Selective Adrenoceptor Antagonist

Terazosin hydrochloride, a quinazoline derivative, is a long acting α1-selective adrenoceptor antagonist with a similar pharmacodynamic profile to prazosin [P0938]. Terazosin is known to relax vascular and prostate smooth muscle through blockade of α1-adrenoceptors, and lowers blood pressure by decreasing peripheral vascular resistance. In in vitro experiments, terazosin has been shown to contractions in human prostatic tissue, and it is used in the treatment for prostatic hyperplasia (BPH). In addition, some studies indicate that α1-selective adrenoceptor antagonists show suppression of human prostate cancer cell growth. (The product is for research purpose only.)
