说明

一般說明

A sulfonylurea that selectively blocks ATP-sensitive K⁺ channels. Reduced K⁺ conductance causes membrane depolarization and influx of Ca²⁺ through voltage sensitive Ca²⁺ channels. Blocks vascular smooth muscle relaxation produced by K_ATP channel openers. Inhibits the vasorelaxing effects of nitric oxide.

Antidiabetic sulfonylurea that selectively blocks ATP-sensitive K⁺ channels. Reduced K⁺ conductance causes membrane depolarization and influx of Ca²⁺ through voltage sensitive Ca²⁺ channels. Blocks vascular smooth muscle relaxation produced by K_ATP channel openers. High-affinity binding sites are widely distributed and have been identified in the cardiovascular system, the central nervous system, and pancreatic β-cells. In cultured cells, glyburide enhances insulin action and stimulates the synthesis of glucose transporters. Displays large potency difference in action on pancreatic tissue (IC₅₀ in nM range) and vascular tissue (IC₅₀ in µM range).
