  • Name: chlorpropamide
  • Chemical Name: chlorpropamide
  • CAS Number: 94-20-2
  • Molecular Formula: C10H13ClN2O3S
  • Molecular Weight: 276.740
  • Catalog: API Hormone and endocrine-regulating drugs Pancreatic hormones and other blood sugar regulating drugs

  • Chlorpropamide is an oral antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus (NIDDM).Target:Chlorpropamide belongs to the sulfonylurea class of insulin secretagogues, which act by stimulating β cells of the pancreas to release insulin.Chlorpropamide is not recommended for the treatment of NIDDM as it increases blood pressure and the risk of retinopathy. Up to 80% of the single oral dose of chlorpropramide is metabolized, likely in the liver; 80-90% of the dose is excreted in urine as unchanged drug and metabolites.
