Alpha blocker used as anti hypertensive agent_____________?
Correct answer: B. Prazosin
- A. Alpha methyl DOPA
- B. Prazosin
- C. Clonidine
- D. Propranolol
Explanation
Prazosin selectively blocks post-synaptic alpha-1 receptors, relaxing arterioles and veins to lower blood pressure. Alpha-methyldopa and clonidine reduce sympathetic outflow centrally, while propranolol is a beta blocker rather than an alpha blocker.
