Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Hypertensive Urgency

Intervention: nicardipine intravenous (Drug); Labetalol (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: The Cleveland Clinic

Official(s) and/or principal investigator(s):
W. Frank Peacock, MD, Principal Investigator, Affiliation: The Cleveland Clinic
Joseph Varon, MD, Principal Investigator, Affiliation: The University of Texas Health Science Center, Houston


The purpose of this study is to compare the safety and efficacy of Cardene I. V. to labetalol administered intravenously for the management of hypertension in the emergency department setting.

Clinical Details

Official title: A Phase IV, Randomized Trial to Determine the Efficacy and Safety of Cardene Intravenous (I.V.) Versus Labetalol for Management of Hypertensive Emergencies in the Emergency Department Setting

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Percentage of Subjects Achieving a Pre-defined Target Systolic Blood Pressure (BP) Within 30 Minutes.

Secondary outcome:

Average Number of Dose Titrations Within 30 Minutes

Emergency Department(ED)Time to Disposition Decision

Treatment Failure

Subjects Requiring the Use of Intravenous Rescue Medications

Transition Time to Oral Medication

Detailed description: More than 3 million patients yearly receive an intravenous antihypertensive agent in the US. Despite this large number of critically ill patients treated annually, little research exists in the area of acute severe hypertension, specifically hypertensive emergency, a serious condition that contributes to morbidity and mortality. Two agents that are commonly used to treat acute hypertensive crisis include labetalol and nicardipine. Cardene may provide benefits in titration and has shown to have lower dosage adjustments compared to labetalol. Nicardipine has also shown a decreased need for additional antihypertensives when compared to labetalol in patients with stroke in a neurological ICU.
