Chronotherapy’s opportunities of a fixed combination of perindopril 10 mg/indapamide 2.5 mg in patients with a lack of night reduction in blood pressure

Abstract

Currently, adequate reduction of blood pressure (BP) during the night in patients with arterial hypertension remains important problem. To study chronotherapy’s opportunities to achieve better BP control by a single dose of antihypertensive drugs while maintaining high compliance. Aim. To evaluate the efficacy, tolerability, safety of various prescription regimes of fixed combination: perindopril 10 mg and indapamide 2.5 mg in patients with insufficient degree of BP reduction at night. Design and methods. The study included 30 patients (20 men and 10 women, 56±9.3 years, body mass index 30.5±5.3 kg/m2, the duration of arterial hypertension - 7.1±5.8 years), on ineffective dual antihypertensive therapy (BP>140/90 mm Hg). Initially, ambulatory BP monitoring (ABPM) and blood tests were performed. Then, previous therapy was terminated and fixed combination of perindopril 10 mg/indapamide 2.5 mg (Noliprel A Bi-forte) was administered. Patients were randomized into two groups: morning and evening regimens of therapy. After 8 weeks of treatment ABPM and blood tests were repeated. Statistical analysis was done after further separation of patients into groups with sufficient (dippers) and insufficient (non-dippers) degree of BP reduction at night. Results. In the group of "non-dippers" average ambulatory systolic BP (SBP) during wakefulness declined from 149.4±11.7 mm Hg to 129.8±10.6 mmHg (p
