Description: Candoxatrilat, also known as U 73967 and UK69578, is an active neutral endopeptidase inhibitor that reduces degradation of atrial natriuretic peptide. Candoxatrilat reduces the clearance of atrial natriuretic factor in both intact and nephrectomized rats: evidence for an extrarenal site of action.
