This study evaluated the anti-hypertensive efficacy, tolerability and effects on left ventricular mass of losartan, a selective angiotensin II receptor antagonist, after 22 months in patients with essential hypertension. The study included 77 hypertensive patients who were randomised at baseline to 22 months double-blind once daily treatment with losartan 50 mg (L group n = 44 patients, mean age 54 ± 9 years) or hydrochlorothiazide 25 mg (HCTZ group, n = 33 patients, mean age 56 ± 7 years). Routine haematology, blood chemistry, standard electrocardiography, echocardiography and ambulatory non-invasive 24-h blood pressure (BP) monitoring were performed at baseline and after 10 and 22 months. The results showed good tolerability and a significant mean systolic and diastolic BP reduction in all groups (L group: 22 mmHg and 11 mmHg; HCTZ group: 11 mm Hg and 7 mm Hg, respectively for systolic and diastolic mean BP). Moreover, a remarkable reduction in left ventricular mass index was reached after 10 and 22 months only in the L group (L group: Δ = -11 g/m2, P < 0.02; HCTZ group: h = -5 g/m2, P = 0.38). In conclusion, losartan was well tolerated and produced a significant reduction in BP and left ventricular mass in hypertensive patients.

Abstract

This study evaluated the anti-hypertensive efficacy, tolerability and effects on left ventricular mass of losartan, a selective angiotensin II receptor antagonist, after 22 months in patients with essential hypertension. The study included 77 hypertensive patients who were randomised at baseline to 22 months double-blind once daily treatment with losartan 50 mg (L group n = 44 patients, mean age 54 ± 9 years) or hydrochlorothiazide 25 mg (HCTZ group, n = 33 patients, mean age 56 ± 7 years). Routine haematology, blood chemistry, standard electrocardiography, echocardiography and ambulatory non-invasive 24-h blood pressure (BP) monitoring were performed at baseline and after 10 and 22 months. The results showed good tolerability and a significant mean systolic and diastolic BP reduction in all groups (L group: 22 mmHg and 11 mmHg; HCTZ group: 11 mm Hg and 7 mm Hg, respectively for systolic and diastolic mean BP). Moreover, a remarkable reduction in left ventricular mass index was reached after 10 and 22 months only in the L group (L group: Δ = -11 g/m2, P < 0.02; HCTZ group: h = -5 g/m2, P = 0.38). In conclusion, losartan was well tolerated and produced a significant reduction in BP and left ventricular mass in hypertensive patients.
