The Given

Objective: A new, simple, sensitive, precise, reproducible UV visible spectrophotometric method was developed for the estimation of Carbimazole in Tablet dosage form. Methods: The UV spectrum of Carbimazole in methanol and distilled water (30:70) showed λ max at 289.6nm. Beer’s law is valid in the concentration range of 10-50µg/ml. This method was validated for linearity, accuracy, precision, ruggedness and robustness. Results: The method has demonstrated excellent linearity over the range of 10-50µg/ml with the regression equation y = 0.0232x + 0.0466, and regression coefficient i.e, r2= 0.9992 moreover, the method was found to be highly sensitive with LOD (1.818µg/ml) and LOQ (5.509µg/ml). Conclusion: From the results it can be concluded that the given method can be successfully applied for assay of Carbimazole in Tablet dosage form.

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.

The novel smartphone based colorimetric application called PhotoMetrix-PRO has been used for quantitative analysis of Emtricitabine in bulk and tablet dosage form and it compared with conventional UV –visible spectrophtotometry. Smartphone based colorimetric method and UV method was based on detection of intensity of color with increasing concentration Ammonium metavanadate (inorganic oxidizing agent) which was used for preparation Mandeline reagent they used as coloring agent for colour development .The reagent is orange red colour but when it react with Emtricitabine it convert into green color complex. The developed methods have good linearity 50-250μg/ml. The color intensity of API increase with increasing concentration. All images were captured through mobile phone and analysed in PhotoMetrix PRO application. This application convert image into Red, Green and Blue(RGB)histogram and regression models were built into PhotoMetrix-PRO Application both the method have correlation coefficient R2>0.995.The LOD and LOQ for PhotoMetrix PRO  4.77μg/ml and14.92μg/ml and UV-visible spectrophotometry method 4.99 μg/ml and 14.96 μg/ml respectively. The % RSD of Emtricitabine by PhotoMetrix PRO and UV method was 99% (%RSD <2). Appling statistical tool i.e paired two test on both the methods result indicate that both methods are equally significant. Keywords: Smartphone, PhotoMetrix PRO, UV Spectrophotometry, RGB

A simple, economical, precise, and accurate new UV-visible spectrophotometric baseline manipulation method for simultaneous determination of tenofovir disoproxil fumarate (TE) and emtricitabine (EM) in combined tablet dosage form has been developed. The method is based on baseline manipulation (difference) spectroscopy where amplitudes at 261 and 289.9 nm were selected to determine TE and EM, respectively, in combined formulation, and distilled water was used as solvent. Both drugs obey Beer’s law in the concentration ranges of 4–20 μg/mL for TE and 6–30 μg/mL for EM. The results of analysis have been validated statistically, and recovery studies confirmed the accuracy of the proposed method which was carried out by following the ICH guidelines.
