[Economics of nephroprotection in arterial hypertension and type 2 diabetes mellitus]

Based on results of large-scale controlled trials of irbesartan (I), valsartan (V) and amlodipine (A) (PRIME and MARVAL) we carried out the Markov s modeling of their pharmacoeconomic parameters in arterial hypertension (AH) combined with diabetes mellitus type 2 (DM 2) and microalbuminuria (MAU) projected for 8-years perspective. Cost and efficacy was evaluated taking into account years of life gained and outcomes of concomitant diseases and complications. Indexes of cost/efficacy (C/E) were calculated for each drug. Among investigated drugs I appeared to be the most economic at the account of retardation of development of terminal nephropathy and cardiovascular diseases. The use of I compared with V could save 565300 rub/100 patients/year. C/E of I was 26.5 and 37.4% lower that those of V and A, respectively. Costs of year of life saved was 12716, 16432, and 18325 for I, V, and A, respectively. Comparative pharmacoeconomic modeling of 8-year economic perspectives of I, V and A demonstrated financial benefits of I.
