III. How Glibenclamide Works

A. Understanding the Mechanism of Action

The mode of action of Glibenclamide is quite complex. This medication works by attaching itself to the ATP-sensitive potassium channels (KATP) found on the membranes of pancreatic beta cells. When it binds to these channels, they close, causing the cells to depolarize and opening calcium channels. The entry of calcium ions then stimulates the release of insulin-containing granules. It is resulting in higher levels of insulin being released into the bloodstream. Consequently, this helps to lower blood glucose levels.

B. Pharmacokinetics and Pharmacodynamics of Glibenclamide

Once taken orally, Glibenclamide gets absorbed efficiently within our gastrointestinal tract. Thanks to its superior bioavailability rate. It enters our bloodstream rapidly and achieves peak concentrations approximately within 2 6 hours post-ingestion​a​​tion​ (Lewis et al., n.d.). To a large extent, Glibenclamide binds itself to proteins present in plasma. Cytochrome P450 enzyme system, located in the liver. Plays a key role in metabolizing this drug (Lewis et al., n.d.). The primary route of excretion for these metabolites is through bile, while secondary elimination occurs through urine. When considering its pharmacodynamic aspects. Glibenclamides' main therapeutic function revolves around lowering blood glucose levels. It accomplishes this by enhancing insulin secretion from pancreatic beta cells that are still fully functional (Koda Kimble et al., 2012). Furthermore, Glibenclamide may have the ability to bolster the sensitivity of peripheral tissues toward insulin which consequently enhances glucose uptake and utilization.

IV. Uses and Applications of Glibenclamide

A. FDA-approved Indications
