To evaluate the influence of renal impairment on the safety and efficacy of repaglinide in type 2 diabetic patients.


This multinational, open-label study comprised a 6-week run-in period, continuing prestudy antidiabetic medication, followed by a titration period (1-4 weeks) and a 3-month maintenance period. Patients with normal renal function (n = 151) and various degrees of renal impairment (n = 130) were treated with repaglinide (maximal dose of 4 mg, three times daily). Safety and efficacy assessments were performed at baseline (end of run-in) and at the end of study treatment.


The type and severity of adverse events during repaglinide treatment were similar to the run-in period. The number of patients with adverse events was not significantly related to renal function during run-in or repaglinide treatment. Percentage of patients with hypoglycemic episodes increased significantly (P = 0.007) with increasing severity of renal impairment during run-in but not during repaglinide treatment (P = 0.074). Metabolic control (HbA(1c) and fasting blood glucose) with repaglinide was unchanged from that on previous antidiabetic medication. Final repaglinide dose tended to be lower for patients with severe and extreme renal impairment than for patients with less severe renal impairment or normal renal function (P = 0.032).


Repaglinide has a good safety and efficacy profile in type 2 diabetic patients complicated by renal impairment and is an appropriate treatment choice, even for individuals with more severe degrees of renal impairment.
