An Attempt to applying Hydrotropy Technique for Titrimetric estimation of Ketoprofen using Sodium salicylate as Hydrotrope
Ketoprofen used as a Non-steroidal anti-inflammatory drug selected as a poorly water-soluble model drug. Due to the poorly soluble nature of Ketoprofen liberate reduced bioavailability. Hydrotropic solubilization technique is a promising technique used to improve the solubility of water-insoluble drugs. In this investigation, 2M sodium salicylate has been employed in the titrimetric estimation of Ketoprofen and shows synergistic enhancement in the solubility of Ketoprofen by many folds as compared to the distilled water. It excluded the use of various organic solvent like ethanol; methanol and chloroform widely utilized in the titrimetric estimation of various poorly soluble drugs but due to the higher cost, volatility, toxicities lead to environmental pollution hence are the cons of it. The proposed method is new, simple, precise, and inexpensive. The results of the analysis have been validated statistically. The mean % recoveries were found to be close to 100, indicating the accuracy of the proposed method. Low values of standard deviation, % coefficient of variation, and standard error further proved the reproducibility and precision of the proposed method.
