Outcome Measures

Primary Outcomes (1)

  • Target reaching rate within 30 min

    Proportion of subjects whose systolic blood pressure dropped to the target range (decrease ≥ 15% and ≤ 25% from baseline) in the first 30 minutes of administration.

    30 min

Secondary Outcomes (2)

  • Mean time of target reaching

    Procedure (whole infusion duration)

  • Rate of successful conversion to oral antihypertensive drugs

    6 hours after intravenous administration

Study Arms (2)

Clevidipine Butyrate Injection

EXPERIMENTAL
Drug: Clevidipine Butyrate Injection

Ncardipine Hydrochloride Injection

ACTIVE COMPARATOR
Drug: Ncardipine Hydrochloride Injection

Interventions

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.

Clevidipine Butyrate Injection

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.

Ncardipine Hydrochloride Injection

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 and ≤ 75, regardless of gender.
  • Blood pressure increased seriously in a short time, systolic blood pressure (SBP) \> 180 mmHg and (or) diastolic blood pressure (DBP) \> 120 mmHg (measured at an interval of 5 minutes, both blood pressure values should be \> 180 / 120 mmHg), accompanied with progressive target organ damages as below or evidences of other target organ damage can be confirmed:
  • Hypertensive encephalopathy: headache, dizziness, irritability, nausea, vomiting, blurred vision and other symptoms;
  • Acute left heart failure: dyspnea, pulmonary rales, edema and other symptoms;
  • Unstable angina pectoris: ischemic chest pain with ST-T dynamic changes. Patients with SBP ≥ 220mmhg and / or DBP ≥ 140mmHg should be considered as hypertensive emergency;
  • The legal representative and / or patient agree to participate in this clinical trial and sign an informed consent form.

You may not qualify if:

  • Patients with arterial dissection, acute hemorrhagic or ischemic stroke, and acute coronary syndrome in urgent need of surgical or emergency intervention;
  • Patients with severe aortic stenosis or severe mitral stenosis;
  • Patients with obstructive hypertrophic cardiomyopathy;
  • Patients who have used other intravenous antihypertensive drugs within 2 hours before entering this study;
  • Patients known to be intolerant or allergic to calcium channel blockers, or allergic to test drug ingredients, or allergic to soy / soy products or egg / egg products;
  • Patients with lipid metabolism defects, such as pathological hyperlipidemia, lipid nephropathy, or acute pancreatitis with hyperlipidemia;
  • Combined with other serious organ injury or serious complications which may affect the life of the subjects;
  • Patients with a history of mental illness;
  • Patients with known history of alcohol / drug abuse;
  • Those who have participated in other clinical trials and used test drugs 3 months before the trial;
  • Pregnant and lactating women;
  • Researchers do not consider it appropriate to participate in the clinical trial.
