Which drug among the list is used to treat type 2 diabetes?

• A. Ibuprofen
• B. Ambroxol
• C. Bisacodyl
• D. Gliclazide

Answer: (D)

The treatment idea here is drugs that boost insulin release to help manage blood glucose in type 2 diabetes. Gliclazide is a sulfonylurea that acts on pancreatic beta cells by closing ATP-sensitive potassium channels. This depolarizes the cell, opens calcium channels, and triggers insulin secretion in response to meals. Because it relies on functional beta cells, it improves glucose control when there is some remaining insulin production and is a common oral agent in type 2 diabetes.

The other drugs do not address diabetes. Ibuprofen is an NSAID used for pain and inflammation, ambroxol is a mucolytic/expectorant for respiratory conditions, and bisacodyl is a stimulant laxative.
