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.
