Pharmacology Simulation: Drug Action & Receptor Binding
This pharmacology simulation models drug-receptor interactions at the molecular and physiological levels, showing how agonists activate receptors, antagonists block them, and dose-response curves quantify the relationship between drug concentration and effect. Students investigate concepts such as efficacy, potency, EC50, and therapeutic index, and can compare the effects of full agonists, partial agonists, and competitive antagonists at the same receptor. It provides a conceptual foundation relevant to pharmacology, physiology, and health science courses.
What you can do in this simulation
- Bind agonist molecules to receptors and observe downstream cellular effects at varying concentrations
- Plot dose-response curves and identify EC50, maximum efficacy, and slope parameters
- Add a competitive antagonist and watch the dose-response curve shift rightward without changing maximum effect
- Compare full agonists versus partial agonists in terms of efficacy at saturating concentrations
- Explore the therapeutic index and understand how the margin between effective and toxic doses varies across drugs
