Drug interactions can result from pharmacokinetic alterations (eg, changes in absorption, distribution, and elimination), pharmacodynamic changes (additive, synergistic, or antagonistic effects), or a combination of both. Interactions between drugs in vitro (eg, precipitation when mixed in solutions for intravenous administration) are usually classified as drug incompatibilities, not drug interactions.
