Abstract

Climbazole is a topical antifungal agent commonly used to treat human fungal skin infections such as dandruff and eczema. The goal of research work was to develop and validate a simple, precise, quick, and highly efficient UV spectrophotometric approach for quantifying Climbazole in bulk and shampoo dosage form. The quantification was completed using a twin beam UV spectrophotometer at 222 nm and ethanol (99.9%) as the solvent for the estimate. The Climbazole calibration curve exhibit strong correlation coefficient (R 2 =0.9938) and high linearity in the range of 5-25 µg/ml concentrations. The accuracy was found to be between 98.21%-99.83%. The accuracy of the approach was proved by the percent relative standard deviation being less than 2.0%. It was observed that the intraday and interday precision found within acceptable ranges. The method's sensitivity was assessed using the detection limit and quantification limit, which were discovered to be 2.37 µg/ml and 7.20 µg/ml, respectively. In this paper, we introduce a UV-spectrophotometric technique for investigating Climbazole using ethanol as solvent. The suggested method demonstrated excellent selectivity, specificity, and linearity in accordance with ICH Q2 (R1) requirements. Also, marketed pharmaceutical formulations were used to show the developed approach's efficiency and a high recovery rate. It is obvious that the suggested method will serve as a normative approach for the regular testing of Climbazole in pharmaceutical formulations and bulk dosage forms.
