Abstract

We prospectively evaluated long-term (12 months) effects of telmisartan on blood pressure (BP), circulating renin-anigiotensin-aldosterone levels, and lipids in hypertensive patients. There were 13 men and 11 women, 59 ± 8.7 years of age (mean ± SEM), with untreated essential hypertension. The 20-60 mg doses of telmisartan were administered once daily in the morning until BP130/85 was obtained. Blood pressure and plasma renin activity, plasma angiotensin (Ang) I and Ang II, serum angiotensin-converting enzyme (ACE) activity, plasma aldosterone concentration, plasma human atrial natriuretic peptide (hANP) concentration, and serum lipids were obtained 6 and 12 months after starting telmisartan administration. Systolic and diastolic BP were significantly (P < 0.001, P < 0.001) decreased from 162 ± 3.3 and 97.7 ± 2.1 mmHg to 128 ± 3.8 and 79.6 ± 2.0 mmHg after 12 months of treatment, respectively. Plasma Ang I and Ang II were unchanged at 12 months. Plasma renin activity and serum ACE activity were significantly (P < 0.001, P < 0.05) increased and plasma aldosterone concentration was unchanged during the study period. Total cholesterol levels were unchanged, but serum triglycerides levels were significantly decreased at 12 months (P < 0.01). Plasma hANP showed no significant alteration throughout the 12-month period. In hypertensive patients, telmisartan is a beneficial antihypertensive drug that also lowers serum triglycerides.
