Question 1 of 5
Regarding the drug interactions of sulphonylureas, all of the following are correct EXCEPT:
Correct Answer: C
Rationale: Sulfonylureas (e.g., glyburide) interact with drugs affecting their efficacy. Salicylates (choice A) displace them from proteins, increasing free drug and hypoglycemia risk. β-blockers (choice B) mask symptoms like tachycardia, except sweating, complicating detection. Glucocorticoids (choice D) raise glucose, countering sulfonylureas. Thiazide diuretics (choice C) don't potentiate but reduce efficacy by increasing glucose via insulin resistance, making this the incorrect statement. This distinction is key for managing polypharmacy in diabetes, ensuring proper monitoring and adjustment of therapy.
