Abstract

The invention provides a method for detecting dissolution rate of alogliptin benzoate tablets. The method comprises the following steps: by adopting a Welch Ultimate AQ-C18 5-micron chromatographic column of 4.6*150mm, taking a mixed solution of phosphate aqueous solution with the pH value of 5.5-6.5 and acetonitrile as a mobile phase, performing isocratic elution, and detecting the dissolution rate of the alogliptin benzoate tablets on the liquid chromatography system. The detection method provided by the invention is economic, rapid and high-efficiency, has high specificity and is suitable for detecting the dissolution rate of the alogliptin benzoate tablets under different dissolution medium conditions.

Description

technical field [0001] The invention belongs to the field of medicine and chemical industry, and more specifically relates to a method for detecting the dissolution rate of alogliptin benzoate tablets by liquid chromatography. Background technique [0002] Alogliptin Benzoate, chemical name 2-(6-((3R)-3-aminopiperidin-1-yl)-3-methyl-2,4-dioxo-3,4-dihydropyrimidine -1 (2H) base) methyl) benzonitrile monobenzoate, structural formula: [0003] [0004] Chemical formula: C 18 h 21 N 5 o 2 ·C 7 h 6 o 2 Molecular weight: 461.5 [0005] It is a serine protease dipeptidyl peptidase IV (DPP-IV) inhibitor, which can maintain the levels of glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) in the body, and promote the secretion of insulin. So as to exert the hypoglycemic effect. The use of alogliptin benzoate for treating type 2 diabetes has been well known by the public, and its effect in treating type 2 diabetes is good. At present, t...
