The DDI Marker Studies Knowledgebase (replacing the previous combined and individual lists of CYP/P-gp substrates and perpetrators) has been updated in July 2022, and is available in the DIDB Resource Center.
In addition to substrates, inhibitors and inducers of CYPs and transporters, the Knowledgebase provides useful information on the compounds therapeutic class, clinical recommended dosage, pharmacokinetics (e.g. dose proportionality accumulation ratio, time to steady-state), QT prolongation, and NTI characteristics.
As always, feel free to contact us if you have any questions or comments.
