Efficacy and tolerability of fixed amlodipine/valsartan combination was studied in 86 patients with hypertensive disease hospitalized in departments of general internal medicine or cardiology. All patients had indications for antihypertensive therapy and were randomized either to fixed combination amlodipine/valsartan (n=43) or to therapy which corresponded to the hospital formulary (n=43). Correction of antihypertensive therapy was performed by treating physician at daily rounds. Self-control of blood pressure (BP) was performed by patients with the use of UA767PC apparatus. Results of BP self-control were compared with clinical measurements in order to detect concealed inefficacy of treatment. Results. Rate of achievement of target BP with fixed combination amlodipine/valsartan (93%) was comparable with that on traditional therapy (90%). But the use of fixed combination amlodipine/valsartan compared with traditional therapy was associated with lower clinical and self measured BP, quicker achievement of target BP (5.8±2.3 and 9.2±1.8 days, respectively, p<0.05), lesser number of antihypertensive drugs (2.5±0.6 and 3.0±0.9 days, respectively), lower rate of concealed inefficacy of treatment (12 and 31%, respectively, p<0.05). Conclusions. We have demonstrated appropriateness of inhospital administration of fixed amlodipine/valsartan combination as an approach allowing to achieve target BP in shorter time, with the use of fewer antihypertensive drugs, and diminishing concealed inefficacy of treatment.
