Paclitaxel is a taxane diterpene amide and was first isolated from the stem bark of the Pacific yew tree, Taxus brevifolia. This natural product has proven to be useful in the treatment of a variety of human neoplastic disorders such as platinum-resistant ovarian cancer, breast cancer, and non-small cell lung cancer and leukemia, AIDS-related Kaposi' s sarcoma, and other cancers. In this work, paclitaxel, a poorly water-soluble compound, was formulated with hydroxypropyl-β-cyclodextrin (HP-β-CD) and poly(L-lactic acid) (PLLA) in order to enhance its solubility and achieve controlled release. First, HP-β-CD and PLLA were inclusion complexed using a ultrasound-assisted solution method. Paclitaxel-loaded inclusion complex microparticles were then prepared by a supercritical aerosol solvent extraction system (ASES) process. The effects of pressure, temperature, solution concentration, and CO2 flow rate on the morphology, drug content, encapsulation efficiency, and release characteristics were investigated in detail. The physicochemical properties of ASES processed microparticles were characterized by FE-SEM, HPLC, and DSC.
