title: Acute natriuretic effect of fasidotrilat, a mixed inhibitor of neutral endopeptidase and angiotensin I-converting enzyme, in rats with heart failure.
abstract: The acute diuretic and natriuretic effects of fasidotrilat, a mixed inhibitor of neutral endopeptidase (NEP) and angiotensin I-converting enzyme (ACE) were evaluated in control and myocardial-infarcted rats. Fasidotrilat injection (10 mg/kg i.v.) had no significant effect on arterial blood pressure and led to significant elevations in urine volume (+57% in control rats and +114% in infarcted rats) and of urinary sodium excretion (+81% in control rats and +225% in infarcted rats). Comparison between control and infarcted rats showed that fasidotrilat-induced changes in diuresis and natriuresis were higher in infarcted rats (2.4-fold for diuresis and 4.7-fold for natriuresis, p < 0.05), despite a lower perfusion pressure (-10 mm Hg) in infarcted rats. These data show the potential therapeutic interest of mixed NEP/ACE inhibitors in congestive heart failure.
