Solubility Enhancement of Resveratrol by Effervescence Assisted Fusion Technique

Abstract

The basic reason behind this study was to enhance the solubility rate of resveratrol which will finally enhance the dissolution i.e. the rate of drug release due to which the absorption of the drug will increase. The method applied here was effervescent assisted fusion technique. Various batches were prepared by employing water soluble carrier and sodium bicarbonate. The results obtained from the study revealed that the solubility of the drug can be increased up to 10 times than compared with the pure drug in various solvents i.e. phosphate buffer and distilled water. The compatibility study showed no interaction between drug and the excipient while the micromeretics property showed good flow property with good compressibility property. The percent yield of the dispersions prepared ranges between 79.20±0.28% - 89.38±0.25% while the drug release data showed a better rate of drug release than compared with the pure drug which ranges between 10.87% - 99.14%. The pure drug was having a drug release of less than 70% while the optimized batch F5 was having a drug release of more than 95% in the specific period of time. The XRD data showed that the drug’s crystalline structure was not hampered during the preparation while the SEM data revealed the surface shape of the pure drug which was tile shaped and the prepared dispersion was of flakes like formation. From the study it can be concluded that the methods employed in this study can be proven to be a excellent method for enhancing the solubility of the drug up to 10 folds.
