REPAGLINIDE - REPAGLINIDE TABLET AVKARE, INC. ---------- REPAGLINIDE TABLETS, USP 1 MG AND 2 MG RX ONLY DESCRIPTION Repaglinide is an oral blood glucose-lowering drug of the meglitinide class used in the management of type 2 diabetes mellitus (also known as non-insulin dependent diabetes mellitus or NIDDM). 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. The structural formula is as shown below: Repaglinide is a white to off-white powder with molecular formula C H N O and a molecular weight of 452.6. Repaglinide tablets contain 1 mg or 2 mg of repaglinide. In addition each tablet contains the following inactive ingredients: dicalcium phosphate (anhydrous), microcrystalline cellulose, corn starch, meglumine, croscarmellose sodium, povidone, poloxamer, magnesium stearate, and colloidal silicon dioxide. The 1 mg and 2 mg tablets contain iron oxides (yellow and red, respectively) as coloring agents. CLINICAL PHARMACOLOGY 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. 27 36 2 4 PHARMACOKINETICS ABSORPTION: After oral administration, repaglinide is rapidly and completely absorbed from the gastrointestinal tract. After single and multiple oral doses in healthy subjects or in patients, peak plasma drug levels (C ) occur within 1 hour (T ). Repaglinide is rapidly eliminated from t Lire le document complet
