Repaglinide is a novel insulin secretagogue developed in response to the need for a fast-acting, oral prandial glucose regulator for the treatment of type 2 (non-insulin-dependent) diabetes mellitus. Repaglinide is metabolized mainly in the liver; its pharmacokinetics may therefore be altered by hepatic dysfunction. This open, parallel-group study compared the pharmacokinetics and tolerability of a single 4 mg dose of repaglinide in healthy subjects (n = 12) and patients with chronic liver disease (CLD) (n = 12). Values for AUC and Cmax were significantly higher in CLD patients compared with healthy subjects, and the MRT was prolonged in CLD patients. Values for tmax did not differ between the groups, but t1/2 was significantly prolonged in CLD patients compared with previously determined values in healthy subjects. AUC was inversely correlated with caffeine clearance in CLD patients but not in healthy subjects. Blood glucose profiles were similar in both groups. Adverse events (principally hypoglycemia) were similar in the two groups; none was serious. Repaglinide clearance is significantly reduced in patients with hepatic impairment; the agent should be used with caution in this group.
