Pharmacology is often the “make or break” subject for medical and nursing students. It’s one thing to understand how a disease works; it’s an entirely different beast to memorize the thousands of chemicals we throw at those diseases. Between the tongue-twisting generic names and the complex biochemical cascades, it’s easy to feel like you’re drowning in a sea of side effects.

The secret to passing Pharmacology isn’t just staring at a drug chart until your eyes cross. It’s about application. You need to see how examiners frame “clinical scenarios” to trick you into picking the wrong receptor. That is why we’ve assembled a comprehensive General Pharmacology Past Paper Vault for you to download and master.
Before you dive into the PDFs, let’s test your baseline with some of the “frequent flyers” found in previous years’ exams.
Pharmacology Q&A: The Essentials of Drug Action
General Pharmacology focuses on the “rules” that all drugs follow. If you don’t master these, the specific drug classes (like antibiotics or antihypertensives) won’t make any sense.
1. What is the difference between Pharmacokinetics and Pharmacodynamics?
Think of it as a two-way street:
-
-
Pharmacokinetics (PK): What the body does to the drug. This involves the “ADME” process—Absorption, Distribution, Metabolism, and Excretion.
-
Pharmacodynamics (PD): What the drug does to the body. This is the study of biochemical and physiological effects, such as how a drug binds to a receptor to lower blood pressure.
-
2. Why is “First-Pass Metabolism” a nightmare for drug dosing?
When you swallow a pill, it goes to the stomach, then the small intestine, and then—crucially—straight to the liver via the portal vein. The liver is a detox machine; it often destroys a huge chunk of the drug before it ever reaches the systemic circulation. This is why the oral dose of a drug (like Propranolol) is often much higher than the intravenous dose.
3. What is the “Therapeutic Index,” and why should you care?
The Therapeutic Index (TI) is the ratio between the dose that is toxic and the dose that is effective.
-
Wide TI: Think Ibuprofen. It’s hard to accidentally overdose.
-
Narrow TI: Think Warfarin or Digoxin. The difference between “curing” and “killing” is tiny. Examiners love asking about narrow TI drugs because they require constant blood monitoring.
4. Can you explain the difference between a Competitive and Non-competitive Antagonist?
-
Competitive Antagonists are like two people fighting for one seat. If you add enough of the “right” drug (the agonist), you can eventually kick the antagonist off the receptor. The $V_{max}$ stays the same, but the $K_m$ increases.
-
Non-competitive Antagonists are like someone coming along and breaking the seat entirely. No matter how much agonist you add, the receptor won’t work. The $V_{max}$ decreases.
Why You Should Practice with Past Papers
Reading a textbook is passive; answering a past paper is active. By using our downloadable resources, you will:
-
Spot the “Must-Knows”: You’ll notice that certain concepts, like Half-Life ($t_{1/2}$) and Bioavailability ($F$), appear in almost every single paper.
-
Master the Math: Pharmacology involves calculations (Loading Doses, Clearance, etc.). Doing these under exam pressure is the only way to ensure you don’t freeze up on the big day.
-
Decode the Language: Examiners use specific phrasing. Learning to spot “inverse agonist” vs. “partial agonist” in a sentence can be the difference between a pass and a fail.
