Pharmacoeconomic evaluation of fixed-dose triple combination for antihypertensive therapy in Ukraine

In Ukraine, the efficacy of treatment of arterial hypertension is only 19% in urban areas and 8 % in rural populations. The most important reasons of low efficiency of antihypertensive therapy (AHT) are a wrong choice of tactics of the patient management and low adherence of patients to treatment. The latter decreases with increasing amounts of prescribed drugs. One possible way to increase patients’ compliance to treatment and the effectiveness of therapy is to use fixed-dose combinations (FDCs) of antihypertensive drugs (AHDs). The share of FDCs consumption (in terms of DDDs/1000/day) in Ukraine in the total structure of AHDs consumption is 25%, which is significantly less than the proportion of patients (60%), requiring combined AHDs. This is an indirect evidence of low compliance of Ukrainian patients to HD treatment and the need of pharmacoeconomic study of benefits of antihypertensive therapy using FDCs. As a result of pharmacoeconomic cost-effectiveness analysis it has been found that antihypertensive therapy in patients with moderate and severe AH using triple FDC Val+Aml+HCTZ compared with three dual FDC: Val+HCTZ, Val+Aml, Aml+HCTZ provides greater clinical efficacy (the number of patients with the achieved target level of blood pressure). This triple FDC Val+Aml+HCTZ has pharmacoeconomic benefits (greater cost efficiency), compared with only one dual FDC Val+HCTZ. This gives the opportunity to save money, presents additional advantages in efficiency and justifies benefits from its use by hypertensive patients in need of appointing the third AHD CCB amlodipine in addition to the existing dual one using valsartan and hydrochlorothiazide.
