Problems solved by technology

Before the present invention, despite the addition of metal ion chelating agent (ethylenediaminetetraacetic acid salt) or cysteine ​​related substances (specific components are 2,6-diisopropylbenzoquinone and 3,3',5 , 5'-tetraisopropyldiphenoquinone) content can be reduced to some extent, but the above inventions do not solve the oxidation problem of propofol as a phenolic hydroxyl structure, resulting in relatively high content of related substances in the prepared samples, especially After the sample is sterilized by high temperature, the content of related substances such as 2,6-diisopropylbenzoquinone and 3,3',5,5'-tetraisopropyldiphenoquinone increases significantly, and a single metal ion chelation method is used to Mixture (ethylenediaminetetraacetic acid salt) or cysteine ​​after sterilization, related substances increase more, etc.

Abstract

The present invention relates to emulsion medicine injection of propofol comprising propofol, metal ion chelating agent and cysteine. The present invention solves well the problem of the oxidation of phenol hydroxyl group in effective component propofol to produce degradation product and can ensure safety of clinical administration.

Description

technical field [0001] The invention relates to a drug injection emulsion and a preparation method thereof, in particular to a drug injection emulsion of propofol and a preparation method thereof. Background technique [0002] Propofol, due to its hypnotic properties, induces and maintains general anesthesia and is used for sedation in intensive care units. Before the present invention, despite the addition of metal ion chelating agent (ethylenediaminetetraacetic acid salt) or cysteine ​​related substances (specific components are 2,6-diisopropylbenzoquinone and 3,3',5 , 5'-tetraisopropyldiphenoquinone) content can be reduced to some extent, but the above inventions do not solve the oxidation problem of propofol as a phenolic hydroxyl structure, resulting in relatively high content of related substances in the prepared samples, especially After the sample is sterilized by high temperature, the content of related substances such as 2,6-diisopropylbenzoquinone and 3,3',5,5'-t...
