Brief Summary

This clinical trial is designed to assess the effect of hepatic impairment on the pharmacokinetic and pharmacodynamic of glufast tablets 10 mg.

Detailed Description

Mitiglinide calcium hydrate (Glufast Tablets) is an insulinotropic agent of the glinide class with rapid onset and is chemically designated as (+)-monocalcium bis[(2S,3a,7a-cis)-α-benzylhexahydro-γ-oxo-2-isoindolinebutyrate] dihydrate.By transiently increasing insulin secretion, mitiglinide exerts a hypoglycemic effect with rapid onset and short duration of action.This effect results from the inhibitory effect of mitiglinide on the ATP-sensitive potassium (KATP) channel current through binding to sulfonylurea receptor in pancreatic cells.

In an in vitro study, it was confirmed that mitiglinide is metabolized in liver and kidney, and the glucuronide and hydroxyl metabolites are mainly produced by drug metabolizing enzyme,UGT1A9 and 1A3, and by CYP2C9, respectively.Considering that the patient population with T2DM to be targeted appears to have hepatic impairment and the effects of liver dysfunction on pharmacokinetics and pharmacodynamics of mitiglinide are still unknown, this study was designed to investigate the pharmacokinetics (PK), pharmacodynamics (PD) and safety of mitiglinide when administered to T2DM patients with impaired hepatic function.
