What it does

This skill performs systematic Drug-Drug Interaction assessments using real-time literature retrieval from PubMed, CrossRef, and web sources. It produces structured reports following the Micromedex Drug-Reax classification framework, including:

  • Severity grading: Contraindicated / Major / Moderate / Minor
  • Documentation grading: Excellent / Good / Fair / Poor / Unlikely
  • Onset classification: Rapid / Delayed / Not specified
  • Mechanism analysis: Pharmacokinetic (CYP450, P-gp, renal) and Pharmacodynamic (additive, synergistic, antagonistic)
  • Clinical management recommendations with monitoring parameters and alternatives

Triggered by `/drug-drug DrugA DrugB` or natural language queries about drug interactions.
