Repaglinide

Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026

Repaglinide is a short-acting oral insulin secretagogue used before meals to improve postprandial glucose control in adults with type 2 diabetes. It can cause hypoglycemia, especially if meals are skipped or when combined with glucose-lowering supplements or interacting drugs. Concomitant gemfibrozil is contraindicated because it markedly increases repaglinide exposure.

In short

What the research says.

A quick, data-only summary. The full evidence, dosing, and sources are below.

Repaglinide is a short-acting oral insulin secretagogue used before meals to improve postprandial glucose control in adults with type 2 diabetes. NutriStack rates the supporting evidence as strong. Common adult dosing is 0.5-4 mg orally before meals, usually 2-4 times daily; maximum 16 mg/day; skip dose if meal is skipped, though a prescriber sets the actual dose. This profile indexes 3 sources.

The science

How it works, mechanistically.

Core mechanism

Repaglinide binds ATP-dependent potassium channels on pancreatic beta cells, causing membrane depolarization, calcium influx, and meal-timed insulin release. It is metabolized mainly by CYP2C8 and CYP3A4 and transported partly by hepatic uptake pathways, so inhibitors can increase hypoglycemia risk and inducers can reduce efficacy. Its short duration is why it is dosed before meals and skipped when a meal is skipped.1,2
