CA 2377614

The present invention relates to an anesthetic composition for intravenous injection, characterized in that it contains propofol (2,6-diisopropylphenol) and a poloxamer as the surfactant. The composition of the present invention can optionally contain at least one co-surfactant selected from the group consisting of Solutol HS 15, egg lecithin, Labrasol, polyoxy 10- oleyl- ether, tween, ethanol and polyethylene glycol. Since the composition of the present invention is prepared in the form of a microemulsion having a particle size of 100nm and below, it has a superior technical effect that it is thermodynamically stable, can be aseptically filtered to prevent the microorganisms contamination, and further, can be readily prepared and can minimize side effects including embolism and hypereipidemia, etc.

La présente invention concerne une composition d'anesthésiant en injection intraveineuse caractérisée en ce qu'elle comprend du propofol (2,6-diisopropylphénol) et un poloxamère intervenant comme tensioactif. Cette composition peut éventuellement contenir au moins un co-tensioactif appartenant au groupe des Solutol HS 15, lécithine de l'oeuf, Labrasol, polyoxy-10-oleyl-éther, tween, éthanol et polyéthylène-glycol. Etant donné que la composition se prépare sous forme d'une micro-émulsion d'un calibre particulaire de 100 nm au maximum, elle présente un intérêt technique en ce qu'elle est thermodynamiquement stable, qu'elle se filtre en asepsie de façon à empêcher toute contamination par les micro-organismes, qu'elle est facile à élaborer, et qu'elle présente moins de risques d'effets secondaires, notamment d'embolie et d'hyperlipémie.
