bulk drugs and the drug formulations and its validation. Method: The ideal conditions were established for the investigation or analysis of the drug. Results: The λmax of 293.2nmwas found for the Sildenafil citrate. Within, 8 to 60μg/ml concentration range the method complied with Beer's Law and show exceptional sensitivity with linearity. Moreover, 1.012 and 3.036 were observed limit of detection and quantification, respectively. When the absorbance versus concentration graph was plotted on the calibration curves a linear relationship was observed with the coefficient correlation of 0.99. The observed regression coefficient (Y) of the calibration curves was found to be 0.0131x- 0.0191. The method was precise and accurate with the experiential value of 2.0325± 0.044. The stability of the test solution was up to 48 hours. Conclusion: The proposed analytical method is simple, economical and experimentally less time-consuming. Therefore, it will be appropriate for Sildenafil citrate analysis of pharmaceutical formulations in bulk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
