Abstract

A cleviprex fat emulsion concentrated solution, a preparation method and an application thereof belong to the field of pharmacology and pharmaceutics. According to the invention, the defect that a traditional fat emulsion preparation technology is complex and stability is poor is overcome. The preparation technology provided by the invention is simple; the general physical stirring process is only needed; and no homogenization technology is required. A product prepared in the invention can be sterilized through a 0.22-micron microfiltration membrane; in clinical use, the product can be spontaneously emulsified after diluted by the use of an aqueous solution such as normal saline or a glucose solution, etc. and slightly oscillated; and under optimized conditions, average particle size is about 0.2 micron, and injection fat emulsion characteristics are fully embodied. The product has good fluidity, will not be retained on the wall, is single-phase, transparent and clear in appearance, can undergo clarification detection and will not cause preparation stratification after multigelation. The product is used in blood pressure control during surgical operation and control of acute blood pressure elevation after operation, and also can be used in controlling blood pressure of hypertensives who are not suitable for oral administration or fail in oral administration.

Description

Technical field [0001] The present invention is a field of pharmacy and pharmaceuticals, involving a chlorine -butyl -flat fat concentration solution, its preparation methods and uses. Background technique [0002] Clevidipine Butyrate is the third -generation new short -acting dihydrine calcium calcium channel antagonist developed by the British Astrazneca company. It was first listed in the United States in August 2008. The product name Cleviprex?, Is the firstIntravenous injection is blocked with dihydrial hydrogen pyrine calcium channels.CLEVIPREX? It is an injection emulsion, with fast effect and fast effects, and can accurately control blood pressure in the incremental dose.Different from the current intravenous injection of anti -hypertension drugs that have renoma and (or) liver metabolism, they are metabolized in blood and tissue, so they are not accumulated in the body.Banadicate, as a new type of intravenous injection, anti -hypertension drugs represent a major progres...
