NEET PG Pharmacology Recall Questions with Answers\u00a0<\/span><\/h2>\n

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.\u00a0<\/span><\/p>\n

1. Peripheral Neuropathy with Isoniazid\u00a0<\/b><\/p>\n

Question: A patient was started on isoniazid for TB and developed peripheral neuropathy. What should be co-administered to prevent this?\u00a0<\/span><\/p>\n

    \n
  1. Pyridoxine\u00a0<\/span><\/li>\n
  2. Niacin<\/span><\/li>\n
  3. Riboflavin<\/span><\/li>\n
  4. Ascorbic acid<\/span><\/li>\n<\/ol>\n

    \u00a0Answer: A. Pyridoxine\u00a0<\/strong><\/p>\n

    Explanation:<\/strong> Isoniazid interferes with pyridoxine (vitamin B6) metabolism, leading to peripheral neuropathy. Pyridoxine supplementation (10-50 mg\/day) prevents this common side effect.\u00a0<\/span><\/p>\n

     <\/p>\n

    2. Drug Causing Torsades de Pointes\u00a0<\/b><\/p>\n

    Question: Which drug can cause Torsades de Pointes<\/span><\/p>\n

      \n
    1. Amiodarone<\/span><\/li>\n
    2. Sotalol\u00a0<\/span><\/li>\n
    3. Verapamil<\/span><\/li>\n
    4. Lignocaine<\/span><\/li>\n<\/ol>\n

      Answer: B. Sotalol\u00a0<\/strong><\/p>\n

      Explanation:<\/strong> 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.\u00a0<\/span><\/p>\n

      3. Antiemetic in Chemotherapy\u00a0<\/b><\/p>\n

      Question: A patient undergoing chemotherapy develops severe vomiting. Best drug?\u00a0<\/span><\/p>\n

        \n
      1. Metoclopramide<\/span><\/li>\n
      2. Ondansetron<\/span><\/li>\n
      3. Domperidone<\/span><\/li>\n
      4. Aprepitant\u00a0<\/span><\/li>\n<\/ol>\n

        Answer: D. Aprepitant\u00a0<\/strong><\/p>\n

        Explanation:<\/strong> Aprepitant is an NK1 receptor antagonist effective in preventing delayed chemotherapy-induced nausea and vomiting. It\u2019s more potent than 5-HT3 antagonists like ondansetron in this setting.\u00a0<\/span><\/p>\n

         <\/p>\n

        4. Mechanism of Action: Ivermectin\u00a0<\/b><\/p>\n

        Question: What is the mechanism of action of ivermectin?<\/span><\/p>\n

          \n
        1. Inhibits microtubules<\/span><\/li>\n
        2. Enhances GABA-mediated Cl<\/span>\u207b<\/span> influx\u00a0<\/span><\/li>\n
        3. Inhibits DNA synthesis<\/span><\/li>\n
        4. Calcium channel blocker<\/span><\/li>\n<\/ol>\n

          Answer: B. Enhances GABA-mediated Cl\u207b influx\u00a0<\/strong><\/p>\n

          Explanation:<\/strong> 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.\u00a0<\/span><\/p>\n

           <\/p>\n

          5. Longest-Acting Insulin\u00a0<\/b><\/p>\n

          Question: Which insulin has the longest duration?\u00a0<\/span><\/p>\n

            \n
          1. NPH<\/span><\/li>\n
          2. Glargine\u00a0<\/span><\/li>\n
          3. Lispro<\/span><\/li>\n
          4. Regular<\/span><\/li>\n<\/ol>\n

            Answer: B. Glargine\u00a0<\/strong><\/p>\n

            Explanation:<\/strong> 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.\u00a0<\/span><\/p>\n

             <\/p>\n

            6. Contraindicated Antihypertensives in Pregnancy\u00a0<\/b><\/b><\/p>\n

            Question: Which drug is contraindicated during pregnancy?\u00a0<\/span><\/p>\n

              \n
            1. Methyldopa<\/span><\/li>\n
            2. Labetalol<\/span><\/li>\n
            3. Enalapril\u00a0<\/span><\/li>\n
            4. Nifedipine<\/span><\/li>\n<\/ol>\n

              Answer: C. Enalapril\u00a0<\/strong><\/p>\n

              Explanation:<\/strong> Enalapril, an ACE inhibitor, is teratogenic, especially in the 2<\/span>nd<\/span> and 3<\/span>rd<\/span> trimesters, causing renal dysgenesis and fetal death. Safer alternatives include labetalol, methyldopa and nifedipine.\u00a0<\/span><\/p>\n

              \u00a0<\/span><\/p>\n

              7. Unsafe Antibiotics in Pregnancy\u00a0<\/b><\/p>\n

                \n
              1. Penicillin<\/span><\/li>\n
              2. Erythromycin<\/span><\/li>\n
              3. Tetracycline\u00a0<\/span><\/li>\n
              4. Cephalexin<\/span><\/li>\n<\/ol>\n

                Answer: C. Tetracycline\u00a0<\/strong><\/p>\n

                Explanation:<\/strong> Tetracyclines cause permanent discolouration of teeth and inhibition of bone growth in the fetus. Penicillins and cephalosporins are generally considered safe in pregnancy.\u00a0<\/span><\/p>\n

                 <\/p>\n

                8. Drug for Open-Angle Glaucoma\u00a0<\/b><\/p>\n

                Question: Drug of choice for open-angle glaucoma:\u00a0<\/span><\/p>\n

                  \n
                1. Timolol\u00a0<\/span><\/li>\n
                2. Atropine<\/span><\/li>\n
                3. Pilocarpine<\/span><\/li>\n
                4. Acetazolamide<\/span><\/li>\n<\/ol>\n

                  Answer: A. Timolol\u00a0<\/strong><\/p>\n

                  Explanation:<\/strong> Timolol is a \u03b2-blocker that reduces aqueous humour production, effectively lowering intraocular pressure. Pilocarpine is now less commonly used due to side effects and frequent dosing.\u00a0<\/span><\/p>\n

                   <\/p>\n

                  9. Rifampicin- Warfarin Interaction\u00a0<\/b><\/p>\n

                  Question: A patient is on rifampicin and warfarin. What happens to INR?\u00a0<\/span><\/p>\n

                    \n
                  1. Increase<\/span><\/li>\n
                  2. Decrease\u00a0<\/span><\/li>\n
                  3. No change<\/span><\/li>\n
                  4. Fluctuate<\/span><\/li>\n<\/ol>\n

                    Answer: B. Decrease\u00a0<\/strong><\/p>\n

                    Explanation:<\/strong> Rifampicin induces CYP450 enzymes, leading to increased metabolism of warfarin and decreased anticoagulant effect (hence INR falls). Dose adjustment is needed.\u00a0<\/span><\/p>\n

                     <\/p>\n

                    10. Selective COX-2 Inhibitor\u00a0<\/b><\/p>\n

                    Question: Which of the following is a COX-2 selective inhibitor?\u00a0<\/span><\/p>\n

                      \n
                    1. Aspirin<\/span><\/li>\n
                    2. Diclofenac<\/span><\/li>\n
                    3. Celecoxib\u00a0<\/span><\/li>\n
                    4. Ibuprofen<\/span><\/li>\n<\/ol>\n

                      Answer: C. Celecoxib\u00a0<\/strong><\/p>\n

                      Explanation:<\/strong> 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.\u00a0<\/span><\/p>\n
