Effects of Cilnidipine on Heart Rate and Uric Acid Metabolism in Patients With Essential Hypertension

摘要

Background: The relation between hypertension and hyperuricemia has been established by epidemiological studies. Calcium channel blockers are one of the first-line drugs for newly diagnosed patients with essential hypertension. Cilnidipine is a new calcium channel blocker acting by blocking both L- and N-type calcium channels. The aim of this study was to compare the effectiveness of amlodipine and cilnidipine in patients with essential hypertension and their effects on heart rate and serum uric acid levels.Methods: Out of 100 enrolled patients, 92 completed the study. They were randomly assigned to amlodipine (N = 47) and cilnidipine (N = 45) groups. Cilnidipine was started at 10 mg/day and then adjusted to 5 - 20 mg/day, and amlodipine was started at 5 mg/day and then adjusted to 2.5 - 10 mg/day.Results: After 24 weeks of study, patients in cilnidipine groups showed significant reduction in heart rate and serum uric acid levels from baseline (P = 0.00).Conclusion: In clinical setting where both hypertension and hyperuricemia exist, cilnidipine can be a promising drug of choice.Cardiol Res. 2016;7(5):167-172doi: http://dx.doi.org/10.14740/cr494w
