Abstract

Enalapril. a prodrug. is the ethyl ester of a long-acting angiotensin converting enzyme inhibitor. enalaprilat. Because enalapril does not contain any appreciable chromophore. detection of the drug in a complex matrix (e.g.. biological fluids) has been problematic with conventional detection systems in high-performance liquid chromatography (HPLC). As a result. determination of enalaprillevel in blood samples has been typically carried out using HPLC-MS/MS in the literature. (omitted)
