Problems solved by technology

The disadvantages of propofol emulsion injection are: poor physical and chemical stability of the product, greater pain during injection, large particles may block blood vessels, and more complicated emulsion preparation process, and because the product formula does not contain antibacterial agents, the product A large amount of fat in the formula is easy to promote the production of microorganisms
The disadvantage of this formulation is the use of high concentrations (30-60% w / v) of HPβCD which has a significant impact on the safety of the product
It also increases product cost
The formula must be stored at 2-8°C, which brings inconvenience to transportation and storage

Abstract

The invention belongs to the pharmaceutical field, and relates to a propofol composition. The composition contains the following components in ratio by weight that propofol: cyclodextrin: albumin is 0.1-3:0.1-50:0.01-30. The composition has the advantages of good stability, significantly reduced injection pain, simple production process and low cost.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to a propofol composition with good stability and simple production process. Background technique [0002] Propofol (2,6-diisopropylphenol) is a widely used intravenous anesthetic. Due to the poor water solubility of propofol, it is difficult to prepare propofol in aqueous solution. The current commercially available product is emulsion injection, which is composed of soybean oil, egg phospholipids, glycerin and the like. The disadvantages of propofol emulsion injection are: poor physical and chemical stability of the product, greater pain during injection, large particles may block blood vessels, and more complicated emulsion preparation process, and because the product formula does not contain antibacterial agents, the product A large amount of fat in the formula is easy to encourage the production of microorganisms. Therefore, during the use of propofol emulsion, attention must be paid to ...
