ABSTRACT
Albendazole, a BCS class II drug, has poor dissolution characteristic. In order to enhance dissolution nanocrystals were prepared by antisolvent precipitation process using PVP K-30(0.05%,0.1%,0.2%,0.4%) as stabilizer. The process was optimized in terms of concentration of stabilizer(PVP K 30) in order to enhance dissolution and obtain stable particles with a small mean particle size. Nanocrystals were characterized with respect to particle size, in vitro dissolution and X-ray diffraction pattern. Decrease in particle size of nanocrystals was observed with increase in concentration of stabilizer. Dissolution of nanocrystals also improved with increase in concentration of PVP K-30. Crystalline state evaluation before and following particle size reduction was conducted through XRD to denote any possible transformation to an amorphous state during process.
