Safety and Efficacy Study of Clevidipine Butyrate Injection in Hypertensive Emergencies

A Randomized, Single Blind, Positive Parallel Controlled, Multicenter, Phase III Clinical Trial of Clevidipine Butyrate Injection in the Treatment of Hypertensive Emergencies

The purpose of this study was to determine the efficacy and safety of clevidipine for treating Hypertensive emergencies（defined as systolic blood pressure >180 mmHg and/or diastolic blood pressure >120 mmHg, accompanied by acute organ damage）.

Inclusion Criteria:

1. Age ≥ 18 and ≤ 75, regardless of gender.

2. 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;

3. The legal representative and / or patient agree to participate in this clinical trial and sign an informed consent form.

Exclusion Criteria:

1. Patients with arterial dissection, acute hemorrhagic or ischemic stroke, and acute coronary syndrome in urgent need of surgical or emergency intervention;

5. 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;
6. Patients with lipid metabolism defects, such as pathological hyperlipidemia, lipid nephropathy, or acute pancreatitis with hyperlipidemia;
7. Combined with other serious organ injury or serious complications which may affect the life of the subjects;
8. Patients with a history of mental illness;
9. Patients with known history of alcohol / drug abuse;
10. Those who have participated in other clinical trials and used test drugs 3 months before the trial;
