Abstract
Aim: The main aim of this present investigation is to apply the hydrotropic solubilization phenomenon for spectroscopic analysis of poorly water-soluble drugs to avoid the use organic solvents which may be costlier, toxic to environment, volatile, and pollutant. Materials and Methods: A simple ultra violet spectroscopic method was used for the content analysis by diluting the drug cefixime with various hydrotropic agents. In this study, 20% solutions of sodium salicylate (SS), sodium citrate (SC), sodium acetate (SA), and sodium benzoate (SB) were used as hydrotropes for the analysis of cefixime. Results and Discussion: The drug cefixime showed the linearity of 0.5-2 μg/mL in SS, 5-30 μg/mL in SC, 5-50 μg/mL in SA, and 0.05-0.30 μg/mL in SB solution. Then the proposed methods were validated with respect to accuracy and precision as per International Conference of Harmonization guidelines Q2 (R1), November 2005 (Validation of Analytical Procedures: Text and Methodology). The drug showed less limit of detection (LOD) and limit of quantification (LOQ) values (LOD = 0.0225471 μg/mL and LOQ 0.0683246 μg/mL) to SB solution and it obeyed the Beer's law at very low concentration range (0.05-0.30 μg/mL) which proved that the drug has high sensitivity with SB solution. Conclusions: Finally, it was concluded that the all proposed methods were simple, cost-effective, safe to environment, rapid, reproducible, and highly sensitive with SB solution.
