Mechanism Of Action and Pharmacodynamic Effects Click here for help
Terazosin is a selective α1-adrenoceptor antagonist. It blocks the action of endogenous adrenaline on smooth muscle cells within walls of the bladder and blood vessels. The drug has a relaxation effect on bladder wall musculature and blood vessels. This effect on peripheral blood vessel walls reduces blood pressure. Terazosin relaxes prostatic and urethral smooth muscle thereby improving urinary tract flow in BPH patients.
