Abstract. According to modern clinical recommendations, for effective blood pressure (BP) control from the 2nd stage of arterial hypertension (AH), a combination of at least two antihypertensive drugs (AHDs) with different mechanisms of action should be used. For therapy adherence improving, it is preferable to prescribe fixed combinations (FC) of medicines. Despite the fact that fixed and free combinations of AHDs have been well studied, there are still not enough studies making their comparative analysis.
The aim of the research is a comparative estimation of daily BP profile in patients with stage 2–3 AH while taking a free combination and FC of blockers of angiotensin II receptor and a calcium antagonist.
Material and methods. 60 patients with grade 2–3 of AH, randomized into two groups of 30 people each were involved in the study. The 1st group received FC of losartan with amlodipine, the 2nd group received a free combination of valsartan and amlodipine. The study was carried out over 3 months. At the first and second visits, participants underwent ABPM procedure.
Results. After 3 months from the start of the treatment, the dynamics of ABPM indexes in patients of both groups practically had no difference. A significant decrease in most of the main parameters of the daily BP profile was revealed, with the exception of the rate of morning rise in SBP and DBP, as well as the degree of nighttime decrease in SBP in group 1 and indicators of BP variability in group 2. An intergroup comparison of ABPM parameters revealed a more noticeable difference in all main indicators of SBP and DBP in patients taking FC.
Conclusion. Statistically significant decrease in the main ABPM parameters was observed both when taking the free combination of valsartan and amlodipine, and the FC of losartan with amlodipine. When comparing between groups, a statistically more significant decrease in most ABPM parameters was observed when using FC of losartan with amlodipine. This indicates a more expressed effect of FC at the daily blood pressure profile, which is apparently takes place due not only to increased patients’ adherence to such therapy and its economic feasibility, but also to the additional additive antihypertensive efficacy of AHDs FC.
