  • Publication number: 20060228408
    Abstract: An oral drug delivery system which comprises a biliquid foam comprising: from 1 to 20% by weight of a continuous hydrophilic phase, from 70 to 98% by weight of a pharmaceutically acceptable oil which forms a discontinuous phase, the said pharmaceutically acceptable oil having dissolved or dispersed therein a poorly water-soluble drug in an amount of from 0.1 to 20% by weight and the biliquid foam including therein from 0.5 to 10% by weight of a surfactant to enable the formation of a stable biliquid foam, all percentages being based upon the total weight of the formulation.

  • Publication number: 20050256185
    Abstract: A means and method for treating malaria, schistosomiasis, and cancer using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl on the other side of the trioxolane group, whereby the spirocyclohexyl ring is preferably substituted at the 4-position. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites.

  • Publication number: 20050209345
    Abstract: This invention relates to methods of delivering a medium to highly lipophilic drug to the systemic circulation through the lymphatic transport system including the oral administration to a subject in the fasted state of a formulation comprising the lipophilic drug and a component capable of stimulating the production of endogenous lipid, or a component selected from medium to long chain lipids, pharmaceutically acceptable surfactants and combinations thereof, wherein the component is present in an amount sufficient to enhance or promote lymphatic transport of the lipophilic drug, and corresponding methods for avoiding lymphatic transport.
