Mechanism of action

Acetohexamide binds to an ATP-sensitive K⁺ (K_ATP) channel on the cell membrane of pancreatic beta cells. This inhibits the outflux of potassium, which causes the membrane potential to become more positive. This depolarization in turn opens voltage-gated calcium channels. The rise in intracellular calcium leads to increased fusion of insulin granulae with the cell membrane, and therefore increased secretion of insulin. ^[2]

Risks

Sulfonylureas, especially first-generation sulfonylureas such as Acetohexamide, can cause severe hypoglycemia and increase the risk of adverse cardiovascular events. ^{[3] [4]}
