Rotigotine (RTG) loaded Nanostructure Lipid Carriers (NLCs) were developed for the treatment of Parkinson’s disease. To estimate RTG entrapped in NLCs, UV spectrophotometric method was developed and validated. The solvent and wavelength of detection were optimized in order to maximize sensitivity of the proposed method. The method was validated for different parameters like linearity, precision, specificity, accuracy, limit of detection (LOD), limit of quantitation (LOQ) and robustness as per ICH guidelines. A wavelength maximum of RTG in methanol: chloroform (6:4V/V) mixture was found at 273 nm. The method was found to be linear in the range of 40 to 200 µg/mL with a correlation coefficient (r2 ) of 0.998. The accuracy of the method was studied by recovery study and % recovery was found in range of 99 to 100.37 %. The LOD and LOQ were found to be 0.09 µg/mL and 6.1 µg/mL, respectively. The method is simple, accurate and requires relatively inexpensive instrument. The method was used successfully for determination of RTG loaded into NLCs.

Chromatographic separation was attained on an ACQUITY UPLC™ BEH C18 column (100 mm × 2.1 mm, 1.7 μm) with a mobile phase consisting of 20 mM phosphate buffer (pH 7.0) : acetonitrile in the proportion (60 : 40 v/v) isocratically pumped at a flow rate of 1.25 mL·min−1, and detection was monitored at 305 nm. All analytes were separated simultaneously at a retention time (tr) of 1.42, 2.31, 3.63, and 5.62 min for PAR, TIZ, ACF, and NIM, respectively, with a total run time less than 6.0 min. The proposed method was validated according to ICH guidelines with respect to accuracy, precision, linearity, limit of detection, limit of quantitation, and robustness. Linearity was obtained over a concentration range of 81.25–487.5, 0.5–3.5, 25–150, and 25–150 µg·mL−1 for PAR, TIZ, ACF, and NIM, respectively.

Abstract: A simple, precise and economical UV-spectrophotometric method has been developed for the estimation of Olmutinib from bulk. Two methods were developed First method (A) applied was area under curve (AUC) in which the area was integrated in wavelength from 262-272nm. Second method (B) was first order derivative spectrometric method. In this method absorbance at λmin=256.57nm, λmax=282.83nm and zero cross=267.68nm was measured. Calibration curves were plotted for the method by using instrumental response at selected wavelength and concentration of analyte in the solution. In both the methods, linearity was observed in the concentration range of 2-12µg/ml at the λmax=267.68nm. Accuracy and precision studies were carried out and results were satisfactorily obtained. The drug at each of the 80 %, 100 % and 120 % levels showed good recoveries that is in the range of 98.00 to 99.00% for both methods, hence it could be said that the method was accurate. Limit of detection (LOD) and limit of quantitation (LOQ) were determined for the method. The method was validated as per International Conference on Harmonization. All validation parameters were within the acceptable limit. The developed method was successfully applied to estimate the amount of Olmutinib in pharmaceutical formulation.
