Tolvaptan in API and formulation may now be quantifi ed using a technique. The solution was diluted with acetonitrile and scanned in the UV area between 200 and 400 nm. At 267 nm, tolvaptan exhibits maximum absorption. The accuracy investigations had been executed at3 levels, i.e., 80, 100, and 120%, and recuperation turned into discovered to bewith inside the variety of 99.4% for the tolvaptan, which showed linearity over the range of 5 to 160 g/mL with correlation co-effi cient (r2) of 0.9995. The quantifi cation (LoQ) and detection (LoD) threshold were 0.471 and 1.435 g/mL, respectively. The suggested approach underwent forced deterioration, and each parameter’s degradation was discovered. The ICH rules were followed in the validation of each parameter.
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.
