NCT06322238

Brief Summary

The purpose of this study is to determine whether the implementation of pre-emptive pharmacogenomic (PGx) testing of a panel of clinically relevant PGx markers, to guide the dose and drug selection for 39 commonly prescribed drugs, will result in an overall reduction in the number of clinically relevant drug-genotype associated ADRs which are causally related to the initial drug of inclusion (referred to as 'index drug').
