Objective: A new, simple, sensitive, precise, reproducible UV visible spectrophotometric method was developed for the determination of Dasatinib in Tablet dosage form with­­­ methanol. Methods: The method is based on the formation of a colorlesscomplex. The UV spectrum of Dasatinib in methanol showed maximum wavelength at 248 nm. Beer’s law is valid in the concentration range of 7-35µg/ml. this method was validated for linearity, accuracy, precision, assay, ruggedness and robustness. Results: The method has demonstrated excellent linearity over the range of 7-35µg/ml with the regression equation y = 0.0332x+0.0633 and regression coefficient i.e. r2= 0.9994moreover, the method was found to be highly sensitive with LOD(1.08µg/ml) and LOQ(3.29µg/ml). Conclusion: Based on the results the proposed method can be successfully applied for the assay of Dasatinib in various tablet dosage forms

UV SPECTROPHOTOMETRIC ANALYSIS AND VALIDATION OF OSELTAMIVIRPHOSPHATE IN PURE AND PHARMACEUTICAL FORMULATION

Objective: A new, simple, economical, precise, sensitive, linear, accurate, rapid UV spectrophotometric method has been developed for the estimation of Oseltamivir Phosphate in pure form and pharmaceutical formulation. Methods: This UV method was developed using Methanol as a solvent. In the present method, the wavelength selected for analysis was 218 nm. UV-Visible double beam spectrophotometer (Systronic 2201) was used to carry out spectral analysis. The ICH guidelines were used to validate the method. Results: The method was validated for linearity, range, accuracy, precision, robustness, LOD and LOQ. Linearity was found in the range of 10-50µg/ml. Accuracy was performed by using a recovery study. The amount of drug recovered was found to be in the range of 99.01-100.1%. The % RSD value was found to be less than 2. Conclusion: The developed UV spectrophotometric method was found to be simple, economic, sensitive, easy, accurate, linear, specific and highly sensitive and can be used for routine estimation of Oseltamivir Phosphate
