Abstract
The present invention relates to a pharmaceutical composition for use in treatment of cancer patients. The composition includes at least one taxane present in a pharmaceutical effective amount and a mixture of one or more negatively charged phospholipids and one or more zwitterion (i.e. uncharged) phospholipids. This mixture entraps the at least one taxane in what is believed to be a liposome. The mixture contains a ratio of negatively charged phospholipids to zwitterion phospholipids of 1:9 to 7:3. The taxol is present in an amount of 1.5-8.0 mole percent taxane. The composition is in the form of particles having a size of 0.025 to 10 microns with substantially no taxane crystals.
