A double-blind, parallel group multicentre study was carried out to compare the effects of adding once daily treatment with lisinopril 10 or 20 mg and placebo to the treatment of 100 patients whose blood pressure was inadequately controlled with once daily atenolol 50 mg. Following a two-week run-in period, patients with a lying DBP between 95 mmHg and 115 mmHg were randomised to either lisinopril 10 mg or placebo once daily for four weeks. Blood pressure measurements were made approximately 24 h after the previous dose of study medication.

The activities of enzymes of the urea cycle, carbamoyl phosphate synthetase, ornithine transcarbamoylase, argininosuccinate synthetase, argininosuccinase (the last two comprising the arginine synthetase system) and arginase, were measured in the liver during development of the rat. All five enzymes exhibited relatively low activities in foetal liver and a rapid postnatal increase was found.
