Использование

Mitiglinide Calcium is a blood glucose-lowering drugs, stimulating insulin secretion by closing the ATP-sensitive K+ channels in pancreatic beta-cells

Способ действия

Mitiglinide is another non-sulfonylurea insulin secretagogue. Insulin secretion is physiologically stimulated by the binding of ATP to a cytosolic nucleotide binding site of the membrane bound ATP-sensitive K+ channel which leads to closure of the K+ channel. The inhibition of K+ permeability depolarizes the plasma membrane, subsequently the voltage-dependent Ca2+ channel opens to promote the Ca2+ influx which finally results in insulin secretion. The insulin secretagogues stimulate insulin secretion by closure of this ATP-sensitive K+ channel of pancreatic -cells. KATP-channel consists of two subunits, a functional ion channel pore and a regulatory protein. The binding of the secretagogues is suggested to occur to the separate regulator protein containing the binding sites for sulfonylureas (sulfonylurea receptor 1, SUR1) but also other compounds.
