Abstract
Docetaxel (DTX) is a chemotherapeutic drug with poor hydrophilicity and permeability. Its lipophilic properties decrease its absorption in systemic circulation which hinders its therapeutic efficacy & safety. Cyclodextrins (CDs) with their unique structural properties enhance solubility of chemotherapeutic drugs. The study was designed to formulate docetaxel-cyclodextrins inclusion complexes for enhancement of solubility with sulfobutyl ether β-cyclodextrin (SBE7-β-CD), hydroxypropyl β-cyclodextrin (HP-β-CD) and β-cyclodextrin (β-CD). Further, by using ionic gelation method polymeric nanoparticles of docetaxel-cyclodextrins were prepared with sodium tri poly phosphate (STPP) and chitosan (CS). Optimization is performed by varying CS and STPP mass ratios. Nanoparticles were analyzed for their physicochemical properties, drug-excipient compatibility, thermal stability and oral toxicity. CDs enhanced the solubility of DTX. Nanoparticles were found within 144 to 372 nm diameters with polydispersity ranging 0.117 to 0.375. The particles were found round & circular in shape with smooth and non-porous surface. Increased quantity of drug release was observed from DTX-CDs loaded nanoparticles than pure drug loaded nanoparticles. Oral toxicity in rabbits revealed biochemical, histopathological profile with no toxic effect on cellular structure of animals.
