摘要 |
An emulsion of .alpha.-tocopherol, stabilized by biocompatible surfactants, as a vehicle or carrier for therapeutics drugs, which is substantially ethanol free and which can be administered to animals or humans by various routes is disclosed. Also included in the emulsion is PEGylated vitamin E.
