Beta Blockers | MCQs

Explanation

Atenolol is the beta-blocker with the least entry into the CNS.

It has lower lipophilicity compared to Propranolol.

This reduces its ability to cross the blood-brain barrier.

Explanation

Propranolol is a non-selective beta-blocker that blocks both beta-1 and beta-2 receptors.

Therapeutic uses:

Used to treat conditions like hypertension, angina pectoris, arrhythmias, migraines, and hyperthyroidism. 

Side effects:
