  • StatusFDA approved
  • AdministrationN/A
  • PharmacologyA non-steroidal anti-inflammatory drug (NSAID). Salsalate is in a class of drugs called salicylates. Salsalate may work by inhibiting the production of and release of prostaglandins.
  • Absorption_value100.0
  • Absorption (description)Salsalate is insoluble in acid gastric fluids (< 0.1 mg/ml at pH 1.0), but readily soluble in the small intestine where it is partially hydrolyzed to two molecules of salicylic acid. A significant portion of the parent compound is absorbed unchanged. The amount of salicylic acid available from salsalate is about 15% less than from aspirin, when the two drugs are administered on a salicylic acid molar equivalent basis (3.6 g salsalate/5 g aspirin). Food slows the absorption of all salicylates including salsalate.
