Fosinopril is distinguished from other ACE inhibitors by a pharmacokinetic pecularity in the sense that is can be metabolized either by liver or kidney. This was the rationale of the present research the aim of which was to verify if administered to patients with liver cirrhosis the drug was liable to alter global liver function and ability to metabolize drugs. Eight cirrhotic males, mean age 56 years, also suffering from high blood pressure, were studied. In these patients, liver and kidney function tests (BUN, creatinine blood level, serum and urinary electrolytes, creatinine clearance, calcium and phosphor blood level, transaminases, alkaline phosphatase prothrombin time, cholinesterase, gamma-glutamyl-transpeptidase) were carried out at baseline and after 30 days' fosinopril treatment (1 capsule every morning in the fasting state); in addition total functioning liver mass was assessed by the galactose test, and drug-metabolizing capacity by the antipyrine test. Treatment resulted in a significant improvement of pressure values in all patients (p < 0.01) and did not alter liver and kidney function parameters. Besides, no side effects were registered, especially no case of orthostatic hypotension. The antipyrine test was not influenced by fosinopril treatment. Therefore, short-term treatment with this ACE-inhibitor can be concluded to be effective and not to cause additional alterations of liver function in patients with liver cirrhosis.

The single-dose and steady-state pharmacokinetics of the angiotensin-converting enzyme (ACE) inhibitor fosinopril and its active diacid, fosinoprilat, were evaluated in 6 healthy volunteers and 12 patients with alcoholic cirrhosis. Fosinopril was administered at a dosage of 10 mg once daily for 14 days. Results in the two groups were similar, with no evidence of accumulation of fosinoprilat in hepatically impaired patients. Mean (+/- SD) maximum observed plasma concentrations of fosinoprilat in the healthy subjects were 112.0 +/- 67.2 ng/mL after the first dose and 144.1 +/- 61.7 ng/mL at steady-state. Corresponding values for the hepatically impaired patients were 111.4 +/- 40.1 ng/mL and 140.2 +/- 50.9 ng/mL. The area under the serum concentration versus time curve for healthy volunteers was 790.7 +/- 431.0 ng.hr/mL after the first dose and 940.3 +/- 400.4 ng.hr/mL at steady-state. Similar values were noted in hepatically impaired patients: 926.0 +/- 293.9 ng.hr/mL and 1,255.4 +/- 434.0 ng.hr/mL for first dose and steady-state, respectively. No statistically significant differences were detected in fosinoprilat pharmacokinetic values between healthy and hepatically impaired subjects. Absence of accumulation can be attributed to the dual route of elimination of fosinoprilat reported in previous studies. Renal excretion of fosinoprilat in hepatically impaired patients prevents increased accumulation. The present findings suggest that the starting dose of fosinopril used in hypertensive patients with normal renal and hepatic function can also be used in patients with hepatic impairment secondary to cirrhosis.
