Pharmacology MCQ practice is where many pharmacy students gain or lose rank, because nearly every question is about one drug, one mechanism or one antidote. This quiz gives you 30 such questions covering antidotes, mechanisms of action, drug classes and common adverse effects.
Pharmacology also connects with hospital and clinical pharmacy, so a better score here helps in those papers too. Attempt the quiz first and then go through the explained questions below.

What makes Pharmacology tricky for students
The pharmacology syllabus looks huge, but exam questions follow a few repeating patterns: drug of choice, mechanism of action, antidote for, adverse effect of, and class of. If you prepare drug tables with these five columns, you cover most of what is asked. Students usually lose marks on look-alike drugs, for example atenolol versus propranolol, or ranitidine versus omeprazole.
Five Pharmacology MCQ questions that confuse students
These are the questions from the set above that students most often get wrong, with the reason behind each answer.
- What is the antidote for paracetamol poisoning?
Answer: N-acetylcysteine. It replenishes glutathione and protects the liver. Naloxone is for opioids and flumazenil is for benzodiazepines. - Which beta blocker is cardioselective?
Answer: Atenolol. It acts mainly on beta-1 receptors. Propranolol is non-selective, which is why it is avoided in asthma. - What is the antidote for heparin overdose?
Answer: Protamine sulfate. Vitamin K is the antidote for warfarin, not for heparin. This is one of the most repeated swaps in exams. - How does omeprazole reduce acid?
Answer: By inhibiting the H+/K+ ATPase (proton pump). Ranitidine also reduces acid but it blocks H2 receptors. Same result, different step. - Why is carbidopa given with levodopa?
Answer: It inhibits peripheral dopa decarboxylase. More levodopa then reaches the brain, and side effects such as nausea reduce.

How to get the most out of this practice set
Make a one-page antidote chart with the poison on the left and the antidote on the right, and stick it near your study table. When you review this quiz, read the wrong options as well. Each wrong option is usually another drug with its own exam question, so one MCQ lets you revise three or four drugs at once.
