Abstract

According to the invention, the parenteral administration of water-insoluble pharmacologically active agents is enhanced wherein the agents are administered in the lipoid phase of a carrier emulsion comprising a microemulsion of a finely dispersed lipoid in an aqueous phase. The lipoid preferably has a mean particle size below 1 micron. This makes it possible to administer water-insoluble agents in high concentrations, and thus a lower dose, whereby a rapid onset of the pharmacological effect is accompanied by a markedly reduced incidence of injury to body tissues.
