Abstrakt: Tavaborole, a topical antifungal agent containing Boron is used for the treatment of onychomycosis, an infection of the nail and nail bed caused by Trichophyton rubrum or Trichophyton mentagrophytes infection. Tavaborole is chemically known as 5 - Fluoro -1,3 - dihydro -2,1-benzoxaborol -1-ol. It acts by inhibiting Leucyl-tRNA synthetase an essential fungal enzyme required for protein synthesis. AB SCIEX Instruments LC-ESI-MS/MS (Model no. 5068379-Y) QTRAP Enabled Triple Quad 5500+ with Agilent Zorbox C18 (150 mm x 4.6 mm x 3 µm) column and PDA detector was employed for the present study. The total run time was 10 mins and the detection wavelength was 254 nm. A mixture of 5 mM Ammonium formate: Methanol (30: 70) was used as mobile phase on isocratic mode with 1 ml/min as flow rate. Tavaborole has shown linearity over the concentration range 0.5-100 µg/ml and the proposed method was validated as per ICH guidelines. The proposed method is found to be simple, precise, accurate and suitable for the quantification of the marketed formulations of Tavaborole. Stress degradation studies were performed and the method is found to be selective and specific. [ABSTRACT FROM AUTHOR]
