Ethanol and drug interactions are common, causing harmful effects through pharmacodynamic and pharmacokinetic mechanisms. Chronic alcohol use can decrease drug effectiveness, while long-term use may increase drug sensitivity due to organ damage.

Area of Science:

  • Pharmacology
  • Toxicology
  • Drug Metabolism

Context:

  • Drug interactions with ethanol are frequent but poorly quantified.
  • Interactions can be pharmacodynamic or pharmacokinetic, affecting drug efficacy and safety.

Purpose:

  • To review the mechanisms and consequences of ethanol-drug interactions.
  • To highlight the clinical significance of these interactions for various drug classes.

Summary:

  • Direct interactions occur when ethanol and drugs are co-administered, often leading to supratherapeutic effects and adverse events via pharmacodynamic and pharmacokinetic pathways.
  • Serious interactions involve central nervous system depressants, anti-inflammatories, anti-hypertensives, and warfarin.
  • Chronic ethanol consumption can induce tolerance, reducing drug efficacy during abstinence periods.
