Question

Which mechanism is involved in the absorption of propranolol in the body?

• A. Ion pair transport
• B. Pinocytosis
• C. Phagocytosis
• D. Passive diffusion

Hint:

Basic drugs like propranolol → ion pair transport enhances lipid solubility.

Answer 1

The Correct Option is A

Propranolol, a basic drug, is absorbed by ion pair transport, a process in which the drug forms a neutral complex with an oppositely charged ion to facilitate absorption through the lipid membrane.
