dosage form, method of facilitating the transport of a pharmaceutically active compound across a biological membrane or tissue and pharmaceutically active compound

摘要

2R-dodecyl 2-(N,N dimethylamino)-propionate (R-DDAIP) provides an unexpectedly improved activity in facilitating transport of a pharmaceutically active compound across biological membranes and tissues, compared to S-DDAIP of the same enantiomeric purity, or racemic DDAIP. Purified S-DDAIP is also provided.
