"A new foundational representation of potential drug-drug interactions
(PDDIs) that covers the material entities and processes in the domain
of discourse for PDDI evidence and knowledge claims. The
representation will enable the integration of drug interaction
mechanisms, effects, risk factors, severity, and management options
with the chemical and pharmacological properties (e.g., chemical
structure, function, pharmacokinetic and pharmacodynamic properties)
of the interacting drugs."
