About Pharma-Fix

Match drugs to diseases while dodging interactions and side effects in this free online pharmacology game for students.

Pharma-Fix is a free online pharmacology game where you drag drugs onto the patients they help while dodging dangerous mismatches. This drug mechanism game teaches the difference between a cure and a side effect.

Every drug is a molecule seeking a target. Agonists switch receptors on, antagonists block them and dose determines whether you get therapy or toxicity, the dose-response curve clinicians memorize. The same molecule that relieves pain can also sedate, thin blood or depress breathing when it hits off-target receptors.

The mismatch penalties are real contraindications. Drug interactions can amplify or cancel each other, a statin plus certain antibiotics becomes dangerous and patient factors like kidney function change what a safe dose even means. Pharmacology is matching the right molecule, dose and patient, which is the entire puzzle you solve here.
