BackgroundHypertensive crisis is an acute increase in blood pressure >180/120 mm Hg. A titratable antihypertensive agent is preferred to lower blood pressure acutely in a controlled way and prevent an abrupt overcorrection. Nicardipine and clevidipine are both dihydropyridine calcium channel blockers that provide unique benefits for blood pressure control.ObjectiveThe purpose of this study was to compare the efficacy and safety of nicardipine or clevidipine for blood pressure control in the setting of hypertensive crisis.MethodsThis was a single-center, retrospective cohort study. Eligible patients received either nicardipine or clevidipine for the treatment of hypertensive crisis. The primary outcome was achievement of 25% reduction in mean arterial pressure at 1 h. The secondary outcome was achievement of a systolic blood pressure (SBP) of <160 mm Hg at 2-6 h from the start of the infusion.ResultsThis study included a total of 156 patients, 74 in the nicardipine group and 82 in the clevidipine group. The SBP on admission and at the start of the infusion were similar between groups. There was no difference between groups in achieving a 25% reduction in mean arterial pressure at 1 h. Nicardipine achieved an SBP goal of <160 mm Hg at 2-6 h significantly more often than the clevidipine group (89.2% vs. 73.2%; p = 0.011).ConclusionsThere is no difference between agents for initial blood pressure control in the treatment of hypertensive crisis. Nicardipine showed more sustained SBP control, with a lower risk of rebound hypertension and a significant cost savings compared with clevidipine.Copyright © 2024 Elsevier Inc. All rights reserved.
