作用機序
Chlorpropamide-d4, like chlorpropamide, acts by stimulating the release of insulin from pancreatic beta cells. It binds to ATP-sensitive potassium channels on the pancreatic cell surface, reducing potassium conductance and causing depolarization of the membrane. This depolarization opens voltage-gated calcium channels, leading to an influx of calcium ions and subsequent insulin release .
