ABSTRACT

The Present study was conducted to improve solubility and dissolution of poor water soluble drug Piroxicam. In this research work, Piroxicam Solid Dispersion was prepared kneading method by using, Guar Gum as a carrier. Drug and carriers weight ratio were1:1 to 1:5. The properties of solid were evaluated using Fourier Transform Infra red (FTIR) Spectroscopy, differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and solubility and dissolution studies. The FTIR Spectroscopy showed no chemical interaction between Piroxicam and carrier. DSC studies indicated their no change of melting point of Piroxicam in Solid Dispersion. SEM result showed that Piroxicam was dispersed and was present as amorphous state in the solid dispersions. Solubility of Solid dispersions was highest at Ratio 1:5 is 0.319±0.02 mg/mL. The drug release data of solid dispersion revealed that formulation F5 exhibited more than 95 % drug release after 60 min. Finally we conclude that the solubility & dissolution enhancement is depend on nature and amount of the carrier and when increases the carrier increase the solubility of Piroxicam. Solid dispersion system of Piroxicam and carriers used could improve the solubility and dissolution rate of Piroxicam. Keyword: Solid dispersion, Piroxicam kneading method, Guar Gum
