The purpose of this publication is to show how an elemental impurities excipient database can be used in assisting the execution of a drug product elemental impurities risk assessment as required by the ICH Q3D guidelines.
As a result of this exercise, we have demonstrated that the database, used in conjugation with other sources of information, is a credible source of elemental impurity levels in excipients therefore, a valuable source of information in completion of drug product risk assessments. This useful collection of data helps to reduce the burden of analytical testing for elemental impurities in excipients.
