In this multicentre, prospective, randomized, open-label, blinded-endpoint (PROBE) study, the efficacy of 12 weeks' treatment with once-day telmisartan 40 - 80 mg and enalapril 10 - 20 mg was evaluated using ambulatory blood pressure monitoring (ABPM) in 522 patients with mild-to-moderate essential hypertension. Patients were titrated to the higher dose of study drug at week 6 if mean seated dialistic blood pressure (DBP) was ≥ 90 mmHg. The primary endpoint was the change from baseline in ambulatory DBP in the last 6 h of the 24-h dosing interval after 12 weeks' treatment. Telmisartan and enalapril produced similar reductions from baseline in DBP and systolic blood pressure (SBP) over all ABPM periods evaluated (last 6 h, 24-h, daytime and night-time). Telmisartan produced a significant greater reduction in mean seated trough DBP, measured unblinded with an automated ABPM device in the clinic, amounting to a difference of -2.02 mmHg (P < 0.01). A significantly greater proportion of patients achived a seated dialistic response with telmisartan than enalapril (59% versus 50%; P < 0.05), also measured with the sane ABPM device. Both treatments were well tolerated. Compared with telmisartan, enalapril was associated with a higher incidence of cough (8.9% versus 0.8%) and hypotension (3.9%) versus 1.1%). Therefore, telmisartan may provide better long-term compliance and. consequently, better blood pressure control than enalapril.
