This study was a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the safety and efficacy of oral nicardipine for the treatment of urgent hypertension in the emergency department. Of 57 patients with urgent hypertension 53 patients were enrolled: 36 men and 17 women, 43 black and 10 white, age range 48 +/- 11 years, and diastolic blood pressure 128 +/- 7 mm Hg. Patients were randomly assigned to receive 30 mg nicardipine or placebo in blind fashion followed by 30 mg open-label nicardipine in nonresponders. Responders to one or two doses of nicardipine received 30 or 40 mg nicardipine three times a day for 1 week after discharge from the emergency department. Adequate blood pressure reduction, defined as a reduction of diastolic blood pressure to less than 100 mm Hg or by at least 20 mm Hg, was achieved in 65% and 22% of patients who received 30 mg nicardipine or placebo (p = 0.002). Adequate blood pressure reduction after administration of open-label nicardipine occurred in 76% of the nonresponders to placebo. Blood pressure reductions were maintained at 1 week after discharge. The drug was well tolerated, and no significant adverse events occurred. We conclude that oral nicardipine is a safe and effective drug for the initial treatment of urgent hypertension.
