🎯 MBBS PHARMACOLOGY - HIGH YIELD TOPIC MAP

Based on 20-30 Year PYQ Analysis + NMC Competency Syllabus

📊 EXAM STRUCTURE BREAKDOWN (100 Marks)

Note: If total = 100, likely the 14 short essays are 3 marks each (42) + 5 short answers = 15 + 1 LEQ = 10 + 20 MCQ = 20 → 87. Most likely your exam pattern is: 1×10 + 5×5 + 14×3 + 20×1 = 10+25+42+20 = 97 ≈ 100. I'll prepare for all formats.

• Enzyme inducers (rifampicin, phenobarbitone, carbamazepine)
• Enzyme inhibitors (erythromycin, fluconazole, ketoconazole, cimetidine)
• Bioavailability definition and factors
• Loading dose formula
• Plasma protein binding - warfarin, phenytoin highly bound

ANS MCQs

• Muscarinic receptor subtypes (M1, M2, M3)
• Atropine - which effect not blocked by atropine (sweating)
• Adrenaline reversal (phentolamine)
• Drugs for glaucoma (pilocarpine, timolol, latanoprost)
• Ganglion blocker - mecamylamine, trimethaphan

CNS MCQs

• GABA - which drugs act on GABA (benzodiazepines, barbiturates, valproate)
• Antiepileptic drug of choice for absence seizures (ethosuximide)
• Serotonin syndrome - fluoxetine + MAO inhibitors
• Opioid receptor types (mu, kappa, delta)
• Disulfiram - MOA in alcohol deaddiction
• Neuroleptic malignant syndrome - associated drug class

CVS MCQs

• Digoxin toxicity - first ECG sign (prolonged PR interval)
• Class Ia antiarrhythmic - quinidine
• Heparin reversal - protamine sulfate
• Warfarin reversal - Vitamin K (FFP for emergency)
• ACE inhibitors - which ADR - dry cough (due to bradykinin)
• Drug of choice in hypertensive crisis - sodium nitroprusside

AUTACOIDS/NSAIDs MCQs

• Aspirin - irreversible COX inhibitor
• Drug of choice for gout acute attack - colchicine/NSAIDs
• 5-HT agonist for migraine - sumatriptan (triptan)
• Antihistamine used in motion sickness - promethazine/cyclizine

📚 REVISION STRATEGY TO SCORE 80+

• Day 1-2: General Pharmacology (PK, PD, ADME, ADR, Drug interactions)
• Day 3-4: ANS (Adrenergic + Cholinergic drugs)
• Day 5-6: CVS Drugs (Antihypertensives, Antianginals, Antiarrhythmics, CHF)
• Day 7: Blood drugs (Anticoagulants, Antiplatelets)

• Day 1-2: CNS (Anxiolytics, Antipsychotics, Antidepressants, Antiepileptics)
• Day 3: Opioids + Analgesics + NSAIDs
• Day 4: Local/General Anaesthetics + Skeletal muscle relaxants
• Day 5: Diuretics + Autacoids (Histamine, 5-HT, Prostaglandins)
• Day 6-7: MCQ practice + Short answers revision

Golden Rule: For every drug, always know these 6 things: Classification → MOA → Pharmacokinetics → Uses → ADRs → Contraindications. This structure alone will get you 75+ in any pharmacology paper.
