Efficacy of Low-Dose Hydrochlorothiazide in Combination with Telmisartan on Early Morning Blood Pressure in Uncontrolled Hypertensive Patients

Abstract

Hypertensive patients whose BP was uncontrolled despite the use of antihypertensive agents, including an ARB (candesartan 8 mg/day or valsartan 80 mg/day), were enrolled. The patients were randomly assigned to combination therapy with telmisartan 40 mg/day (changed from current ARB) and hydrochlorothiazide (HCTZ) 12.5 mg/day (T + H, n = 32) or to no change in their current drug regimen (CTL, n = 32). The observation period was 12 weeks. The office and home BPs were significantly reduced in the T + H compared to those in the CTL. A sufficient and long-acting BP lowering effect, as reflected in decreased early morning BP, was obtained with the combination of low-dose HCTZ and telmisartan without apparent metabolic deterioration.
