This document provides recommendations for a minimum information model for information about potential drug-drug interactions. The Report provides non-ambiguous definitions for 10 core information items. It also provides 8 detailed best practice recommendations related to the 10 core information items. Twelve user stories with related goals illustrate use cases for the information model. Adoption of the recommendations by developers of PDDI knowledge artifacts will improve the usefulness of the artifacts within clinical decision support, drug product labels, and other activities relevant to protecting patients from harmful drug interactions.
