Am J Health Syst Pharm ; You may choose a language below to continue to this industry or close this dialog above. S6 effect of a cyclodextrin vehicle on the cardiovascular profile of propofol in rats.
Phagocyte-induced lipid peroxidation of different intravenous fat emulsions and counteractive effect of vitamin E. Chemically, cyclodextrins are stable in base, but they are susceptible to hydrolysis in acid. Haque H, Russell AD: Acute pancreatitis after single-dose exposure to propofol: Furthermore, emulsions need to have a great enough physical stability to withstand heat sterilization and maintain their integrity for their prescribed shelf life.
Not exactly what you want? The critical emulsion component that allows for small oil droplets to be dispersed in the water phase with relatively good stability is the emulsifier. Immune-mediated reactions to althesin alphaxalone. Propofol emulsion mixed with other substances can also destabilize emulsions. Alcohols, C, crwmophor Role of formulation vehicles in taxane pharmacology.
That is, it should have microbe growth potential similar to a nonlipid infusion formulation, such as thiopental. Shaanxi Dideu Medichem Co. Some natural chylomicrons are taken up without metabolism by organ tissues, including cermophor tissue, cardiac muscle, and mammary glands. Metabolic acidosis and fatal myocardial failure after propofol infusion in children: Inclusion complexation of propofol with 2-hydroxypropyl-beta-cyclodextrin: Ceteareth-6 and Stearyl Alcohol.

The objective of this review is to provide a background on propofol formulations, highlight clinical implications of each, and discuss newer efforts to reformulate propofol.
Highly water-soluble derivatives of the anesthetic agent propofol: Sorry, your blog cannot share posts by email. However, micelles made from other poloxamers have been given recent consideration crmophor formulating propofol. Disperse Systems, vol 1. The impetus for adding microbe growth inhibitors to propofol emulsions occurred after the introduction of propofol to the U.
Lipid peroxidation, a generally slow process, can likewise result in emulsion destabilization by degrading the lipid emulsifier or droplet soybean oil.
One comment Good day! Incompatibility of propofol emulsion with anesthetic drugs letter.
China cas 9 China mini cas China fabric cas. Upon administration of a propofol-containing emulsion, propofol diffuses across the droplet interface and passes into the bloodstream. The first lipid emulsions examined were not satisfactory because the onset of anesthesia was delayed, potency was lost, and duration of anesthesia was prolonged compared with propofol formulated in Cremophor EL. Edited by Johnston IDA. Crwmophor Opin Ther Pat ; Therefore, autoclaving can confer a greater stability to the emulsion.
These molecules bridge the interface between the dispersed oil droplets and water. The growing and increasingly aging world population requires improved medical care and an adequate supply of food. An Award for All of Anesthesiology. Review of the toxicologic properties of medium-chain triglycerides.
CREMOPHOR (R) A6 |
The major emulsifier components in egg yolk lecithin, phosphatidylcholine and phosphatidylethanolamine, consist of lipophilic side chains esterified fatty acids bound to polar heads at one end fig. Pharmacodynamics and pharmacokinetics of propofol in a medium-chain triglyceride emulsion. The poloxamers studied exhibited toxicologic problems and were crsmophor given to humans. The influence of medium-chain triglycerides on the stability of all-in-one formulations.
