The humoral and antihypertensive activities of the angiotensin converting enzyme (ACE) inhibitor 2-[N-[(S)-1-ethoxycarbonyl-3-phenylpropyl]-L-alanyl]-(1S, 3S, 5S)-2-azabicyclo[3.3.0] octane-3-carboxylic acid (ramipril, Hoe 498) were investigated in 10 patients with essential hypertension (WHO stage I or II). After a 7-day placebo period, the patients were treated with 5 mg ramipril orally once daily for 14 days. Peak serum concentrations of the active metabolite M1 (dicarboxylic acid) of 5.4-62.0 ng/ml were observed 2-6 h after the first oral dose. The maximum ACE inhibition of 95% was reached 2-4 h after the first oral dose, inhibition exceeded 70% 24 h after dosing. The maximum drop in the systolic and diastolic blood pressure (random zero sphygmomanometer) was measured 4 h after ramipril (p less than 0.02, p less than 0.01), but blood pressure on days 7 and 14 of the treatment period was not different from pretreatment values. Automatically recorded blood pressure results showed a marked reduction of both systolic and diastolic blood pressure during treatment compared to placebo. No side effects occurred. From the present data it is concluded that ramipril is a potent ACE inhibitor in hypertensive patients and that further controlled studies are required for the evaluation of the antihypertensive effect of 5 mg ramipril in essential hypertension.

In a dose titration study patients with mild to moderate essential hypertension were treated with increasing doses of 2-[N-[(S)-1-ethoxycarbonyl-3-phenylpropyl]-L-alanyl]-(1S,3S, 5S)-2-azabicyclo[3.3.0]octane-3-carboxylic acid (Hoe 498) (up to 8 mg daily) for 3 weeks. Hoe 498 was tolerated well. 9 out of 20 patients responded to 1 mg b.i.d., the blood pressure in a further 5 patients normalized with 2 mg b.i.d. Six patients did not respond to Hoe 498 treatment (4 mg b.i.d. in the last week) according to the criterion: recumbent diastolic blood pressure less than or equal to 90 mm Hg. But all 6 patients showed a clear decrease in blood pressure during treatment.
