Influence of processing variables on the solid-state of a model drug, piroxicam in cyclodextrin-based system and its effect on dissolution behavior of the drug was investigated in the present study. Binary systems containing piroxicam and hydroxypropyl-β -cyclodextrin prepared by various processes, were characterized by FTIR, thermal stability, photo stability and dissolution studies. Hydroxypropyl-β -cyclodextrin enhanced the solubility of piroxicam and increased dissolution rates from the binary systems. The complex prepared by co-evaporation method was found to yield better dissolution rate and stability as characterized in present study over those of the complex prepared by other methods.
