What is known and Objective: To evaluate the effects of an olmesartan/amlodipine single pill combination compared with olmesartan or amlodipine monotherapies on blood pressure control, lipid profile, insulin sensitivity and some adipocytokines levels.
Methods: Two hundred and seventy-six patients were enroled in the study and were randomly assigned to take olmesartan 20 mg, amlodipine 10 mg, or a single pill containing an olmesartan/amlodipine combination 20 mg/5 mg for 12 months. We evaluated at the baseline, and after 6 and 12 months: body weight, body mass index, systolic and diastolic blood pressure (SBP and DBP), fasting plasma glucose (FPG), fasting plasma insulin (FPI), lipid profile, adiponectin (ADN), resistin (r), interleukin-1β (IL-1β) and interleukin-5 (IL-5). At the baseline, and after 6 and 12 months, patients underwent an euglycemic, hyperinsulinemic clamp to assess insulin sensitivity (M value).
Results and Discussion: There was a similar decrease in SBP and DBP after 6 and 12 months in all groups, even if olmesartan/amlodipine combination gave a major decrease in SBP and DPB compared with amlodipine and olmesartan monotherapies. Olmesartan/amlodipine combination decreased FPG after 12 months compared with amlodipine monotherapy. Olmesartan/amlodipine combination decreased FPI and HOMA index and increased M value both compared with baseline and compared with olmesartan and amlodipine monotherapies. Both olmesartan and olmesartan/amlodipine increased ADN and reduced r, without significant differences between the two groups. Regarding interleukins, no differences emerged in group to group comparison.
What is new and Conclusion: Olmesartan/amlodipine combination resulted more effective than olmesartan and amlodipine monotherapies in reducing blood pressure, and in increasing insulin sensitivity parameters, but not resulted more effective in improving adipocytokines and interleukins levels analysed, compared with amlodipine or olmesartan monotherapy in hypertensive patients in this double-blind, randomized clinical trial.
