CYP-associated drug–drug interactions: A mission accomplished?

Abstract

On the basis of official Finnish Medicines Authority (Fimea)-approved drug monographs, less than half of the approved small-molecule drugs between 2007 and 2016 were substrates, inhibitors or inducers of CYP enzymes, predominantly of CYP3A4. No significant unexpected, life-threatening, CYP-associated drug-drug interactions (CYP-DDIs) of newly approved drug entities have been observed in the last 10–15 years. The present analysis seems to suggest that tools to study and predict potentially significant CYP-DDIs are working and efficient.
