Associated with adverse drug interactions

Framing

  • Drug-drug interactions arise through pharmacokinetic mechanisms (one drug altering another's absorption, metabolism via cytochrome P450 induction/inhibition, or excretion) or pharmacodynamic mechanisms (additive, synergistic, or antagonistic effects at the same or related receptor systems) - both mechanisms are relevant to predicting and preventing clinically significant interactions
  • See for the specific issue of non-prescription and complementary medicine interactions, often missed given patients' tendency not to volunteer this information unprompted

What sits under this topic

  • See and for organ-function-related pharmacokinetic interaction risk
  • See for the cytochrome P450 mechanism underlying most pharmacokinetic interactions
  • See for polypharmacy as a broader interaction risk factor
