Drug Interaction Key Points
Mechanism
When to use
Raise awareness of common interaction mechanisms. Verify each specific pair in a professional interaction database.
How it works
Mechanism-based groupings (enzyme inhibition/induction, additive QT/serotonin/bleeding/renal effects) with example drug combinations.
Key points
- Not exhaustive and not a substitute for pair-by-pair checking.
- CYP3A4 inhibitors raise statin/CCB/immunosuppressant levels; inducers cause contraceptive/DOAC failure.
- Serotonin syndrome: SSRI/SNRI + MAOI/linezolid/tramadol and others.
- Account for dose, duration and the individual patient.
