Use of esters of polyhydric alcohols to enhance the oral bioavailability of drug substances as well as novel esters and pharmaceutical compositions containing them

摘要: Esters of polyhydric alcohols having 2-8 carbon atoms, said esters containing at least one fatty acid moiety 1-3 atoms and saturated or unsaturated 4-30 are used for the preparation pharmaceutical compositions comprising drug substance such ester enhanced oral bioavailability substance. A method enhancing substances comprises admixing with a formulation. The esters, except those glycerol, novel compounds.
