- D.
Tamsulusin
Correct Answer
A. PrazosinExplanation
Answer is prazosin bcz its non selective alpha 1 antagonist so treats hypertension and prostate enlargement
If he is not hypertensive we will prefer to give tamsulusin which is an α 1 antagonist that is more selective to the α 1 receptor subtype (α 1A ) present in the prostate and less selective to the α 1 receptor subtype (α 1B ) present in the blood vessels.so we won’t have hypotension as side effect,in contrast the prazosinRate this question:
