Propofol will complex to the 2-hydroxpropyl form of this cyclodextrin in a ratio of 1: By continuing to use this website, you agree to their use. Major factors that govern this process for propofol or any lipophilic drug are the drug concentration gradient, the partition coefficient, the drug diffusivity in both phases, and the interfacial area of the drug-containing oil cfemophor.

Studies of paclitaxel, another lipophilic drug formulated in Cremophor, have shown that after injection, the micelles in part function to slow the release of free drug. Propofol in crsmophor medium- and long-chain triglyceride emulsion: Pharmacological characteristics and potential beneficial effects. Propofol has clinical attributes that cause it to be a widely used anesthetic and sedative, but it is a difficult compound to formulate in stable aqueous vehicles suitable for routine clinical use.

Propofol prodrugs are compounds that will degrade, usually in the bloodstream, to release the propofol molecule.
