[Infographic: Drug Class Learning System — Class → Mechanism → Nursing Implications]
Stop Memorising Individual Drugs
There are over 1,000 drugs in the typical nursing pharmacology curriculum. No one can memorise them all. The students who succeed treat pharmacology as a system, not a list.
The Drug Class Framework
For each drug class, master five things:
- Mechanism — what does this class do in the body?
- Indications — what conditions does it treat?
- Key side effects — what are the 2–3 most important ones?
- Nursing implications — what do you monitor, hold, or teach?
- Drug name endings — e.g., “-olol” = beta blocker, “-pril” = ACE inhibitor
📍 Drug Name Suffix Cheat Sheet
“-olol” = beta blockers • “-pril” = ACE inhibitors • “-sartan” = ARBs • “-statin” = statins • “-mycin/-cillin” = antibiotics • “-zole” = antifungals/PPIs
