Question 3 of 5
Acarbose is an inhibitor of the following enzyme:
Correct Answer: B
Rationale: Acarbose (choice B) inhibits α-glucosidase, an enzyme in the small intestine that breaks down complex carbohydrates into glucose, delaying absorption and reducing postprandial glucose spikes in type 2 diabetes. Phosphodiesterase (choice A) is targeted by drugs like sildenafil, unrelated to glucose metabolism. Cyclo-oxygenase (choice C), inhibited by NSAIDs, affects prostaglandin synthesis, not carbohydrates. Cholinesterase (choice D), blocked by anticholinesterases, impacts acetylcholine, not glucose. α-glucosidase inhibition is Acarbose's specific action, making it effective for glycemic control without systemic insulin effects. This mechanism highlights its role in dietary glucose management, distinguishing it from other antidiabetic drugs and aiding in patient education about its GI side effects like flatulence.
