Clinical experience with repaglinide in patients with non-insulin-dependent diabetes mellitus.

Abstract

BACKGROUND:

Repaglinide, a new insulin secretagogue, is purported to be as effective as sulphonylurea but is less hypoglycemic-prone.

OBJECTIVES:

To assess the efficacy of repaglinide and its proclivity for hypoglycemia in a post-marketing study.

METHODS:

The study group comprised 688 patients, aged 26-95 years, clinically diagnosed with non-insulin-dependent type 2 diabetes. The patients were divided into three groups based on previous therapy: a) sulphonylurea-treated (group 1, n = 132); b) metformin with or without sulphonylurea where sulphonylurea was replaced with repaglinide (group 2, n = 302); and c) lifestyle modification alone (drug-naive) (group 3, n = 254). At initiation of the study, all patients were transferred from their current treatment to repaglinide. Only patients in group 2, with combined sulphonylurea plus metformin, continued with metformin plus repaglinide. Fasting blood sugar, hemoglobin A1c and weight were measured at study entry and 4-8 weeks following repaglinide therapy. A questionnaire documented the number of meals daily and the presence of eating from fear of hypoglycemia.

RESULTS:

The fasting blood sugar level of the entire cohort dropped from 191 +/- 2.4 to 155 +/- 2.0 mg/dl (P < 0.0001); HbA1c from 8.8 +/- 0.1 to 7.7 +/- 0.1% (P < 0.0001). The drop of HbA1c in groups 1, 2 and 3 respectively were: 1.04 +/- 0.22% (P < 0.0001), 1.14 +/- 0.24% (P < 0.0001), and 1.51 +/- 0.31% (P = 0.0137). Weight dropped from 81 +/- 0.7 to 80.2 +/- 0.7 kg (P < 0.0001), and eating from fear of hypoglycemia from 157 to 97 (P < 0.001). The daily number of meals decreased from 2.9 +/- 0.4 to 2.4 +/- 0.4 (P < 0.001). No serious adverse reactions occurred during the study.

CONCLUSIONS:

Repaglinide is an effective oral hypoglycemic agent taken either as monotherapy or combination therapy. There is less eating to avoid hypoglycemia, fewer meals consumed, and weight loss.
