Abstract

The invention discloses a propofol medicinal composition for injection, which consists of propofol used as a raw material and soybean lecithin, poloxamer 188, soybean oil, medium chain oil, glycerol, oleic acid and water which are used as auxiliary materials. The propofol medicinal composition for injection has high stability and has more obvious advantages of improving the yield of a product, reducing the cost, implementing the industrialization and further clinically applying the propofol medicinal composition.

Description

technical field [0001] The invention relates to medicines in the field of medicine, in particular to a pharmaceutical composition of propofol for injection. Background technique [0002] Propofol, whose chemical name is 2,6-diisopropylphenol, is a new type of rapid and short-acting intravenous anesthetic commonly used clinically for induction of anesthesia, maintenance of anesthesia, and sedation of critically ill ICU patients. It has the advantages of fast onset of anesthesia induction, rapid recovery and complete functional recovery, and low incidence of postoperative nausea and vomiting. [0003] English name: propofol; [0004] Chemical name: 2,6-diisopropylphenol; [0005] Molecular formula: C 12 h 18 O; [0006] Molecular weight: 178.3; [0007] Indications: Inducer of general intravenous anesthesia, component of "total intravenous anesthesia" or adjunct to anesthesia. [0008] Dosage: The use of propofol usually requires the use of painkillers. Propofol can be...
