Certara Drug Interaction Solutions provides standard and custom solutions to support pharmaceutical researchers, regulatory scientists, and clinicians in evaluating PK-based drug interactions and drug safety. Their core offering is the Drug Interaction Database (DIDB), which contains reliable and up-to-date information curated from preclinical (human in vitro), clinical drug interaction, organ impairment, and pharmacogenetics studies. Founded by Dr. René Levy at the University of Washington, DIDB has been expanded over the years to include various datasets and mechanisms of drug interactions. Certara focuses on enhancing knowledge about the risks of drug interactions through their comprehensive database and custom solutions.
