Interventions

Clevidipine Butyrate InjectionDRUG

Initiate the intravenous infusion of Clevidipine Butyrate Injection at 2 mg/hour. The dose should be doubled every 3 minutes in the first 30 minutes if the desired blood pressure reduction (≥15% and ≤25%) is not achieved and the maximum dose is 32 mg/hour. The infusion duration should be at least 12 hours and less than 72 hours. Oral antihypertensive drugs should be given at about 2 hours before stopping infusion.

Ncardipine Hydrochloride InjectionDRUG

Dilute the Ncardipine Hydrochloride Injection to 0.1mg/ml. Initiate the intravenous infusion at 0.5μg/(kg•min). A 0.5-1μg/(kg•min) dose should be added every 3 minutes in the first 30 minutes if the desired blood pressure reduction (≥15% and ≤25%) is not achieved and the maximum dose is 6μg/(kg•min). The infusion duration should be at least 12 hours and less than 72 hours. Oral antihypertensive drugs should be given at about 2 hours before stopping infusion.
