Abstract

The invention discloses a clevidipine butyrate emulsion and a preparation method thereof. The clevidipine butyrate emulsion includes an oil phase and a water phase. The oil phase comprises clevidipine butyrate, long-chain oil and a stabilizer. The water phase comprises an emulsifier and water. A mass ratio of the oil phase and the water phase is 1:11-1:1. The clevidipine butyrate accounts for 0.05-0.5% of the total mass of the clevidipine butyrate emulsion; the long-chain oil accounts for 10-50% of the total mass of the clevidipine butyrate emulsion; the stabilizer accounts for 0.01-0.5% of the total mass of the clevidipine butyrate emulsion; and the emulsifier accounts for 0.5-5.0% of the total mass of the clevidipine butyrate emulsion. The water phase can also include a metal ion chelating agent and/or an isotonic agent. The emulsion can also include a pH adjusting agent. The clevidipine butyrate emulsion is safe and effective, is less in adverse reactions, is high in drug encapsulation efficiency, is good in storage stability, is controllable in preparation processes and is low in contents of impurities. The method is easy to industrially control.

Description

technical field [0001] The invention relates to a clevidipine butyrate emulsion and a preparation method thereof. Background technique [0002] A hypertensive emergency is a severe clinical manifestation caused by a sharp rise in blood pressure. The "Guidelines for the Prevention and Treatment of Hypertension in China" revised in 2005 pointed out that hypertensive emergencies are severely elevated blood pressure, greater than 180 / 120mmHg, accompanied by progressive target organ dysfunction. The 2007 ESC / ESH European Hypertension Guidelines included perioperative hypertension as a hypertensive emergency. According to the epidemiological data of the United States, 1 / 3 of the patients who come to the emergency department due to hypertensive crisis are hypertensive emergencies. Hypertensive emergencies occur in about 5% of Chinese hypertensive patients. According to literature, the incidence of target organ damage in hypertensive emergencies: encephalopathy 16.3%, intracrania...
