The authors have proposed a new stability indicating RP-HPLC method for the determination of Fingolimod capsules. Symmetry C18 (150 x 4.6 mm, 5µm particle size) column was used for the chromatographic separation with 0.1 % Trifluoro acetic acid: Acetonitrile (50: 50, v/v) mixture as mobile phase. Fingolimod was monitored at 220 nm (UV detector) and the elution was on gradient mode.The flow rate was 1.2 mL/min and the total run time is 10mins. Forced degradation studies were performed to verify the specificity of the method. Beer-Lambert’s law was obeyed over the concentration range 0.5-75 µg/mL with linear regression equation, y = 58537x + 10039 and correlation coefficient 0.9999. The LOD and LOQ are found to be 0.0129 and 0.4061 µg/mL respectively. The proposed method was validated as per ICH guidelines.
