Effects of antihypertensive drugs losartan and levamlodipine besylate on insulin resistance in patients with essential hypertension combined with isolated impaired fasting glucose
Abstract
The objective of this study was to observe the antihypertensive effect of losartan and levamlodipine besylate on insulin resistance in patients with essential hypertension (EH) combined with isolated impaired fasting glucose (i-IFG). Patients (n=244) were randomly assigned to losartan potassium tablets (50-100 mg per day) or levamlodipine besylate tablets (2.5-5.0 mg per day) for intensive antihypertensive treatment with no lifestyle interventions for 3 years. The changes in fasting plasma glucose, fasting insulin (FINS) and insulin sensitivity index (ISI) from before to after treatment were observed. Blood pressure (BP) in each group was significantly reduced by treatment (P<0.05). After 12 months of treatment, the FINS level in the losartan potassium group was significantly decreased and ISI was significantly increased compared with before treatment (P<0.05) and compared with the levamlodipine besylate group (P<0.05). After 24 and 36 months of treatment, FINS was significantly decreased and ISI was significantly improved in both groups compared with baseline (P<0.05), and there was no difference between the groups (P>0.05). The incidence of new-onset diabetes mellitus was not significantly different between two groups. The an...Continue Reading
