Which type of resources includes information on drug interactions, adverse reactions, and pharmacology?

The correct answer is drug compendia, which are comprehensive references that provide critical information on various aspects of medications. These resources typically offer detailed data on drug interactions, adverse reactions, dosing information, pharmacology, and therapeutic uses. Drug compendia serve as essential tools for healthcare professionals to guide safe and effective medication management.

Medical journals may contain studies and reviews involving drug interactions or pharmacology; however, they are not specialized resources focused exclusively on those topics. Clinical trial databases provide information specifically about ongoing or completed clinical trials, including methodologies and results, but they do not focus comprehensively on drug interactions or pharmacology. Additionally, patient health records are individualized documents that contain patient histories and treatment plans; they do not serve as generalized resources for drug information across different medications.
