NEET PG Pharmacology Recall Questions with Answers 

Below are some of the most frequently recalled Pharmacology MCQs from the last 5 years of NEET PG, based on memory and expert analysis. These are designed to help you identify high-yield areas and types of questions typically asked. 

1. Peripheral Neuropathy with Isoniazid 

Question: A patient was started on isoniazid for TB and developed peripheral neuropathy. What should be co-administered to prevent this? 

1. Pyridoxine 
2. Niacin
3. Riboflavin
4. Ascorbic acid

 Answer: A. Pyridoxine 

Explanation: Isoniazid interferes with pyridoxine (vitamin B6) metabolism, leading to peripheral neuropathy. Pyridoxine supplementation (10-50 mg/day) prevents this common side effect. 

2. Drug Causing Torsades de Pointes 

Question: Which drug can cause Torsades de Pointes

1. Amiodarone
2. Sotalol 
3. Verapamil
4. Lignocaine

Answer: B. Sotalol 

Explanation: Sotalol is a class III antiarrhythmic that prolongs QT interval increasing the risk of Torsades de Pointes. Unlike amiodarone which rarely causes Torsades despite QT prolongation, sotalol has a higher arrhythmogenic potential. 

3. Antiemetic in Chemotherapy 

Question: A patient undergoing chemotherapy develops severe vomiting. Best drug? 

1. Metoclopramide
2. Ondansetron
3. Domperidone
4. Aprepitant 

Answer: D. Aprepitant 

Explanation: Aprepitant is an NK1 receptor antagonist effective in preventing delayed chemotherapy-induced nausea and vomiting. It’s more potent than 5-HT3 antagonists like ondansetron in this setting. 

4. Mechanism of Action: Ivermectin 

Question: What is the mechanism of action of ivermectin?

1. Inhibits microtubules
2. Enhances GABA-mediated Cl⁻ influx 
3. Inhibits DNA synthesis
4. Calcium channel blocker

Answer: B. Enhances GABA-mediated Cl⁻ influx 

Explanation: Ivermectin acts on glutamate-gated chloride channels (and GABA in humans), causing hyperpolarisation and paralysis in parasites. This makes it effective in treating filariasis and scabies. 

5. Longest-Acting Insulin 

Question: Which insulin has the longest duration? 

1. NPH
2. Glargine 
3. Lispro
4. Regular

Answer: B. Glargine 

Explanation: Insulin glargine is a long-acting insulin analogue that provides basal insulin coverage for 24+ hours with no pronounced peak. Lispro and regular insulin are short-acting. 

6. Contraindicated Antihypertensives in Pregnancy 

Question: Which drug is contraindicated during pregnancy? 

1. Methyldopa
2. Labetalol
3. Enalapril 
4. Nifedipine

Answer: C. Enalapril 

Explanation: Enalapril, an ACE inhibitor, is teratogenic, especially in the 2nd and 3rd trimesters, causing renal dysgenesis and fetal death. Safer alternatives include labetalol, methyldopa and nifedipine. 

7. Unsafe Antibiotics in Pregnancy 

Question: Which antibiotic is unsafe in pregnancy? 

1. Penicillin
2. Erythromycin
3. Tetracycline 
4. Cephalexin

Answer: C. Tetracycline 

Explanation: Tetracyclines cause permanent discolouration of teeth and inhibition of bone growth in the fetus. Penicillins and cephalosporins are generally considered safe in pregnancy. 

8. Drug for Open-Angle Glaucoma 

Question: Drug of choice for open-angle glaucoma: 

1. Timolol 
2. Atropine
3. Pilocarpine
4. Acetazolamide

Answer: A. Timolol 

Explanation: Timolol is a β-blocker that reduces aqueous humour production, effectively lowering intraocular pressure. Pilocarpine is now less commonly used due to side effects and frequent dosing. 

9. Rifampicin- Warfarin Interaction 

Question: A patient is on rifampicin and warfarin. What happens to INR? 

1. Increase
2. Decrease 
3. No change
4. Fluctuate

Answer: B. Decrease 

Explanation: Rifampicin induces CYP450 enzymes, leading to increased metabolism of warfarin and decreased anticoagulant effect (hence INR falls). Dose adjustment is needed. 

10. Selective COX-2 Inhibitor 

Question: Which of the following is a COX-2 selective inhibitor? 

1. Aspirin
2. Diclofenac
3. Celecoxib 
4. Ibuprofen

Answer: C. Celecoxib 

Explanation: Celecoxib selectively inhibits COX-2, reducing inflammation with fewer GI side effects compared to non-selective NSAIDs. It is used in the treatment of arthritis and other inflammatory disorders.
