RxLinks: Drug Interaction Mechanism Learning Game

RxLinks helps learners understand drug, food, herb, and supplement interactions by linking risks to underlying mechanisms and clinically relevant reasoning for safer medication decisions.

Launch RxLinks View all PharmaNUS webapps

Educational Purpose

RxLinks is designed to make interaction learning more mechanistic. Learners practise connecting an interaction pair or scenario to the mechanism that explains the risk.

The app is part of the PharmaNUS collection of free pharmacology learning webapps, which are developed and updated in response to learner feedback for students and medical and health professions learners.

What Learners Practise

  • Drug-drug, drug-food, drug-herb, and drug-supplement interactions
  • Mechanistic explanations for interaction risk
  • Medication safety reasoning
  • Clinical interpretation of interaction prompts

How To Play

  1. Start an RxLinks interaction round.
  2. Read the interaction pair, prompt, or scenario.
  3. Choose the mechanism or safety implication that best explains the risk.
  4. Review the explanation and clinical reasoning link.
  5. Replay to build a stronger interaction-mechanism map.

Use In Teaching

RxLinks can be used as a short independent practice activity, a warm-up before class, a revision task after teaching, or a prompt for small-group discussion. It works best when paired with debriefing, explanation, and connection back to core pharmacology concepts.
