Question 3 of 5
Which of the following drugs, is an insulin sensitizer:
Correct Answer: B
Rationale: Rosiglitazone (choice B), a thiazolidinedione, enhances insulin sensitivity by activating PPAR-γ receptors, improving glucose uptake in muscle and fat, ideal for type 2 diabetes. Chlorpropamide (choice A), Glipizide (choice C), and Glyburide (choice D), sulfonylureas, stimulate insulin secretion, not sensitivity. Rosiglitazone's sensitizing action contrasts with secretagogues, addressing insulin resistance without hypoglycemia risk. This mechanism is critical for patients with metabolic syndrome, though its use is limited by side effects like fluid retention, requiring careful patient selection.
