title: Comparison of effects of nicardipine and trichlormethiazide on insulin sensitivity in hypertensive patients.
abstract: We performed a randomized, crossover study comparing the effects of nicardipine and trichlormethiazide on insulin sensitivity in 8 untreated essential hypertensive patients. They were treated either with nicardipine or trichlormethiazide for 12 weeks, after which they were treated with the alternative drug for a further 12 weeks. Insulin sensitivity was determined by the hyperinsulinemic euglycemic clamp technique. Nicardipine had no adverse effect on insulin sensitivity. Trichlormethiazide decreased insulin sensitivity index by 12%. As nicardipine does not have an adverse effect on insulin sensitivity, it should be preferred in patients who have a proven metabolic abnormality.
