Measure
Oral Nifedipine
Oral nifedipine: Once diagnosis of hypertensive emergency is confirmed on repeat blood pressure, patients randomized to oral nifedipine will receive 10mg initially, with repeated doses of 20mg every 20min, for up to a maximum of 5 doses or until the therapeutic blood pressure goal of \<160 systolic and \<105 diastolic is achieved. If the therapeutic goal is not achieved after 5 doses, crossover to the alternative study medication will occur.
Intravenous Labetalol
Intravenous Labetalol: Patients randomized to IV labetalol will receive 20mg initially, followed by escalating doses of 40mg, 80mg, 80mg, then 80mg every 20 minutes until the therapeutic goal is achieved, for a maximum of 5 doses. If the therapeutic goal is not achieved after 5 doses, crossover to the alternative study medication will occur.
