Description
Technical field
The present invention relates to pharmaceutical technology fields, and in particular to medicinal liquid injection more particularly to a kind of ring Ba Ming Fat Emulsions note
Penetrate liquid and preparation method thereof.
Ring Ba Ming (Cyclopamine) is steroid alkaloid, may act on Sonic hedgehog (Sonic hedgehog) access,
With potential antitumor activity.Ring Ba Ming is the crystalline powder of white or near-white；It is odorless, it is tasteless.The product have liposoluble
Property, it is readily soluble in ethyl alcohol, acetone or chloroform, it is slightly molten in tea oil or castor oil, it is insoluble in water.It, should in preparation preparation
Rapid delivery preparation is made in indissoluble or the drug for being slightly soluble in water, also to avoid harmful side effect caused by first pass effect, thus,
Common method is that intravenous formulations are made.Technical method is mainly：Soluble-salt is made, cosolvent is added, using mixing
Solvent uses solubilizer.
From blank Fat Emulsion Intralipid in 1961 since Sweden is formally approved for clinic, battalion used for intravenous injection
It supports type Fat Emulsion to be widely used, as the important component of parenteral nutrition, nutrition is provided for critical patient.And in recent years
Come, with the needs of disease treatment and further going deep into for research, the research of Fat Emulsion is no longer confined to answering for parenteral nutrition
It uses, drug is dissolved in and is redispersed in the drug-loaded emulsion that 100-1000nm is made in water phase in fat oil through lecithin emulsification,
The selectivity that administration route can be increased is widely used in intravenous injection, lung, eye and nasal-cavity administration etc..(woods is skilful
Flat, research and application [J] pharmacy of Zhou Jianping Lipid Emulsions as Drug Carriers are in progress, 2005,29 (8):359-364.) in drug containing fat
In fat emulsion injection, most of drug distribution avoids being in direct contact with water in oil phase or oil-water interfaces, for facile hydrolysis or to water
Sensitive drug plays the role of increasing stability.It avoids introducing the intravenous injection irritation that organic solvent generates simultaneously.So
And not all insoluble drug all can be made into fat emulsion injection, and when may also dilute drug be precipitated, note
It penetrates tract pain or causes the problems such as phlebitis, additives are to human body generation toxicity.Therefore, the Fat Emulsion of ring Ba Ming how is developed
Injection has important value.
