Infl uences of Treatment with Amlodipine and Valsartan on Bone Turnover Markers and OPG/RANKL/RANK System in Newly Diagnosed Hypertensive Adults; Which is more Benefi cial?

Abstract

We aimed to investigate the effects of treatment with amlodipine and valsartan, on markers of bone remodeling in newly diagnosed hypertensive adults. Forty-three subjects with newly diagnosed were included in the study. Patients were also randomly divided into two groups, and each group received monotherapy with amlodipine or valsartan. Blood levels of bone turnover markers and osteoprotegerin (OPG) / receptor activator of nuclear factor-κB ligand (RANKL) / RANK system were measured. Amlodipine reduced sRANKL levels and sRANKL/OPG ratio more than valsartan, and this decrease was statistically signifi cant (p<0.001, p=0.002, respectively). Although blood OPG concentration did not change after treatment in both groups, sRANKL/OPG ratio decreased signifi cantly (p<0.001). Amlodipine also caused some reduction in CTx blood levels compared to valsartan. So we can suggest that amlodipine may be a better option than valsartan in patients with osteoporosis or terms of prevention of bone loss in hypertensive adults.
