To assess antihypertensive efficacy of a low-dose combination of amlodipin with lisinopril in the treatment of patients with arterial hypertension (AH) of the second degree.A total of 42 patients with the second degree of AH (16 males, 26 females, mean age 55-9 +/- 1.9 years) entered an open, comparative and controlled trial. They were divided into three groups by the treatment. Group 1 (n = 14) received amlodipin (normodipin, Gedeon Richter) monotherapy in a mean dose 8.9 +/- 0.6 mg/day, group 2 (n = 12) - lisinopril (diroton, Gedeon Richter) in a mean dose 17.5 +/- 1.4 mg/day, group 3 (n = 16) was given combined therapy with amlodipin+lisinopril in a dose 6.8 +/- 0.7 and 8.7 +/- 0.6 mg/day, respectively. The drugs were given for 12 weeks. The efficacy of the treatment was assessed by the results of 24-h monitoring of blood pressure, echocardiography, endothelium-related vasodilatation of the brachial artery (ERVD), dopplerographic investigation of circulation in the middle cerebral artery (MCA), heart rate and cost-effect estimation.Combined low-dose treatment with amlodipin and lisinopril for 12 weeks allowed achievement of target blood pressure in more patients and lower systolic and diastolic blood pressure than monotherapy with each of the drugs. There was also a positive effect on E/A index, ERVD, MCA circulation.Low-dose combined treatment with lisinopril and amlodipin is more effective and cost-efficient. Moreover, lisinopril addition to amlodipin corrects side effects of amlodipin on central nervous system. |
