Enalapril (enalapril maleate) is the maleate salt of enalapril, a derivative of two amino acids; L-alanine and L-proline. Angiotensin converting enzyme (ACE) is a peptidyl dipeptidase which catalyses the conversion of angiotensin I to the pressor substance angiotensin II. After absorption, enalapril is hydrolysed to enalapril at which inhibits ACE. Inhibition of ACE results in decreased plasma. After the initial dose of enalapril was reduced to 2.5 mg daily in high-risk patients, this side effect was less frequent. We conclude that the addition of enalapril to conventional therapy in patients with severe congestive heart failure can reduce mortality and improve symptoms. The beneficial effect on mortality is due to a reduction in death from the progression of heart failure.
