| abstract |
The invention is directed to a biocompatible stable composition containing a hydrophobic drug, such as paclitaxel. The composition, which forms a syringeable polymeric micellar solution in aqueous or body fluids, is a freeze-dried product comprising a hydrophobic drug, i.e. paclitaxel, and an amphiphilic block copolymer wherein a hydrophobic group having affinity or attraction with the hydrophobic drug, such as paclitaxel, is incorporated on its end. The invention provides a shelf life of longer than three years in a sterilized container, stability of longer than three days in infusion fluid, has minimal side effects and shows improved bioavailability. |
