Candoxatril is primarily used in research and clinical studies to investigate its potential therapeutic effects. It functions as an inhibitor of neutral endopeptidase (NEP), an enzyme that breaks down various peptides in the body, including natriuretic peptides. By inhibiting NEP, it increases the levels of these peptides, which can lead to vasodilation, diuresis, and natriuresis. This mechanism makes it a candidate for studying treatments for conditions like hypertension, heart failure, and renal disorders. Its application in experimental models helps to understand the role of NEP in cardiovascular and renal physiology, paving the way for the development of new drugs targeting these pathways.
