The F of a drug impurity was determined by preparing stock solutions from weighed portions of drug and impurity (± 0.05 mg accuracy). Stock solutions were diluted to 1.0, 0.5, 0.25, 0.1, and 0.05% relative to the test solution concentration for determining impurities. The resulting solutions were …
WitrynaWhat would be an appropriate strategy to qualify a new impurity that arises during Phase III or with a commercial product? For example, would it be acceptable that a new unidentified impurity, discovered at the 0.05-0.09% range requires no action to be taken? Would an impurity discovered in the 0.10 to 0.15%, even if it triggers a structural
