Certara acquires Drug Interaction Solutions from the University of Washington
This move represents a significant milestone in the growth and development of the Drug Interaction Database (DIDB®) and further strengthens its position as an internationally recognized authoritative, unbiased, and transparent drug development tool.
DIDB® is an amazing resource
DIDB® is an amazing resource. It streamlines our research of pharmacokinetic parameters for individual drugs and has cut down our time to evaluate a medication by at least 50%. The team there is responsive to questions, and they have a nice training program to orient you to the tool.
The ability to filter drug data in a seemingly infinite number of ways is a key feature.

Precious tool for pharmacologists
DIDB® is a precious tool for clinical pharmacologists; it is of invaluable help for drug-drug interactions, but there is much more, with all the available resources, monographs, and information on PK, effects of hepatic and renal impairment, side and pharmacodynamic effects.
Whilst before I started scholar-googling any new compound I had to deal with, DIDB® is now my starting place.
