  • Publication number: 20100311698
    Abstract: The present invention is directed to aqueous based formulations of water-soluble prodrugs of propofol. The formulations comprise in aqueous medium an effective amount of the water-soluble prodrug of propofol in the absence of an antioxidant. The formulations are particularly useful as intravenous injections. The formulations preferably are buffered to a pH suitable for minimizing degradation of the prodrug during storage. The formulations can be prepared without the use of harmful co-solvents or surfactants and are stable at room temperature over extended periods of time.
