What is repaglinide?

Repaglinide is a prescription medicine that is used to lower blood sugar in patients with high blood sugar (diabetes).

Description

Repaglinide is an oral blood glucose-lowering drug of the glinide class. Repaglinide, S(+)2-ethoxy-4(2((3-methyl-1-(2-(1-piperidinyl) phenyl)-butyl) amino)-2-oxoethyl) benzoic acid, is chemically unrelated to the oral sulfonylurea insulin secretagogues.

Structural Formula of Repaglinide

Repaglinide

Repaglinide USP is a white to off-white solid with molecular formula C27 H36 NO4 and a molecular weight of 452.6. Repaglinide tablets, USP contain 0.5 mg, 1 mg, or 2 mg of repaglinide USP. In addition, each tablet contains the following inactive ingredients: anhydrous dibasic calcium phosphate, corn starch, glycerol, magnesium stearate, meglumine, microcrystalline cellulose, polacrillin potassium, poloxamer, and povidone. In addition, the 1 mg tablet contains ferric oxide (Sicovit Yellow 10) and 2 mg tablet contains ferric oxide (Sicovit Red 30).

 Mechanism of Action

Repaglinide lowers blood glucose levels by stimulating the release of insulin from the pancreas. This action is dependent upon functioning beta (ß) cells in the pancreatic islets. Insulin release is glucose-dependent and diminishes at low glucose concentrations.

Repaglinide closes ATP-dependent potassium channels in the ß-cell membrane by binding at characterizable sites. This potassium channel blockade depolarizes the ß-cell, which leads to an opening of calcium channels. The resulting increased calcium influx induces insulin secretion. The ion channel mechanism is highly tissue selective with low affinity for heart and skeletal muscle.

Before taking repaglinide, tell your doctor:

  • If you are allergic to repaglinide; any part of this medicine; or any other drugs, foods, or substances. Tell your doctor about the allergy and what signs you had.
  • If you have any of these health problems: Acidic blood problem or type 1 diabetes.
  • If you are taking any of these drugs: Clopidogrel, gemfibrozil, or insulin NPH.
  • If you are breast-feeding. Do not breast-feed while you take repaglinide.

This is not a list of all drugs or health problems that interact with repaglinide.

Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take repaglinide with all of your drugs and health problems. Do not start, stop, or change the dose of any drug without checking with your doctor.

What are some things I need to know or do while I take repaglinide?

  • Tell all of your health care providers that you take repaglinide. This includes your doctors, nurses, pharmacists, and dentists.
  • Do not drive if your blood sugar has been low. There is a greater chance of you having a crash.

  • It may be harder to control blood sugar during times of stress such as fever, infection, injury, or surgery. A change in physical activity, exercise, or diet may also affect blood sugar.
  • Low blood sugar may happen with repaglinide. Very low blood sugar can lead to seizures, passing out, long lasting brain damage, and sometimes death. Talk with the doctor.
  • If you are 65 or older, use repaglinide with care. You could have more side effects.
  • Tell your doctor if you are pregnant or plan on getting pregnant. You will need to talk about the benefits and risks of using repaglinide while you are pregnant.
