To master Pharmacology for NEET PG 2026 in 45 days, split the window into three phases:
Days 1–20 — Foundation. One body system every two days. Learn 30–40 drugs each day by mechanism, and solve 10 MCQs on the same drugs the same night.
Days 21–35 — Integration. Stop re-reading. Drill 50 vignette-style MCQs daily, grouped by drug class, with your reasoning spoken aloud.
Days 36–45 — Revision and mocks. Two full Pharmacology-only mini-mocks, reverse-order class revision, and a 20-card daily deck of ADRs and interactions.
This works because Pharmacology typically contributes 15–20 questions to NEET PG and rewards mechanism recognition over rote recall. You do not need to finish Katzung. You need to finish roughly 500 well-chosen MCQs with clean, reasoned explanations.
Forty-five days is enough. The arithmetic is brutal but honest — at five focused hours per day, the window holds more than 200 hours of Pharmacology work. That is more time than most toppers actually spent on the subject across their entire final year. The question is never time. The question is what you do with it.
This guide gives you a concrete, day-by-day architecture, a short list of drug classes that return every year, and the six trap patterns that quietly cost easy marks. Everything is structured around one principle: mechanism first, memorization second. If you understand how a drug meets its receptor, you can reconstruct its uses, side effects, and contraindications under exam pressure. If you only memorize lists, you will freeze the moment NBE rewords the stem.
Why Pharmacology is the single highest-ROI subject in the last 45 days
Pharmacology is the quietest heavy-weight in NEET PG. Most candidates underrate it because the visible marks feel modest — the subject typically contributes somewhere in the 15–20 question range across the paper, depending on the year. That number understates its real value. Pharmacology bleeds into Medicine, Surgery, Pediatrics, Obstetrics, and Psychiatry through drug-of-choice, mechanism, and adverse-reaction questions that are tagged to other subjects but tested through a pharmacological lens.
That is the first reason it is high ROI. The second is that, unlike Anatomy or Biochemistry, Pharmacology rewards pattern recognition more than recall depth. Once you know that beta-blockers reduce cardiac workload by antagonizing β1 adrenergic receptors, you can answer a question about post-myocardial infarction prophylaxis, another about thyrotoxicosis symptom relief, and a third about migraine prevention. Three questions, one mechanism.
The third reason is time efficiency. Pharmacology is modular. You can cover autonomic drugs in a weekend, cardiovascular drugs in three days, antimicrobials in four. Each system is a closed unit, which means you can make measurable progress in a 45-day window without waiting for cross-subject prerequisites to click. Compare this to Physiology, where cardiovascular dynamics and endocrinology interlock through feedback loops that take weeks to internalize.
There is a trap here. Because Pharmacology is so rewarding per hour, students try to stretch the window and end up skimming. The plan below does the opposite. It compresses breadth into the first twenty days and reserves the next twenty-five for the grinding work of vignette pattern recognition and recall maintenance, which is where marks actually get scored.
The 45-day architecture: three phases, three purposes
The plan has three phases. Each one has a single purpose, and you do not move on until that purpose is met. Resist the urge to blend them. The failure mode in fast-track prep is running foundation, integration, and revision in parallel — it feels productive, but every day is shallow.
Phase 1 — Foundation (Days 1–20). Purpose: build the mechanism backbone. Every drug you touch here you name, classify, and attach to a receptor or enzyme. The deliverable at the end of Day 20 is a mental map where, given any drug class, you can list the top five drugs, their mechanism, and one flagship adverse effect.
Phase 2 — Integration (Days 21–35). Purpose: translate mechanism into clinical decision-making. You stop re-reading. You drill vignettes — "a 58-year-old diabetic with chest pain and reduced ejection fraction is started on…" — and you force yourself to verbalize the reasoning chain before you check the answer. The deliverable at the end of Day 35 is instinctive pattern recognition on the common scenarios.
Phase 3 — Revision + mocks (Days 36–45). Purpose: stabilize recall under time pressure. You revise in reverse of the order you studied, so the weakest classes get tested when your memory is freshest. You run two full-length Pharmacology-only mini-mocks under timed conditions. You build a daily 20-card rapid deck of ADRs and interactions and cycle through it every morning.
Phase 1 — Foundation (Days 1–20): drug classes by system
The foundation phase moves one body system every two days. Ten systems, twenty days, with two buffer evenings built in. Miss a day and you slide into buffer; miss two and you eat into Phase 2, which is non-negotiable. The structure forces honesty about your pace.
The daily block is always the same and always three hours, minimum:
90 minutes — core study. Read the drug class from a high-yield source. Prefer Tripathi for Indian context, Katzung for mechanism depth. Do not read both cover-to-cover. Use the index as an entry point.
45 minutes — active recall. Close the book. Write the class on a blank sheet: drugs, mechanism, uses, ADRs, contraindications, one clinical pearl.
45 minutes — 10 MCQs. Solve questions on only that class, with explanations. Questions that reveal a gap get a note in your margin; you revisit that note on Day 8 and Day 20.
The rotation that works for most students — and that parallels the NBE weightage distribution — is: autonomic nervous system, cardiovascular, respiratory, gastrointestinal, renal and diuretics, central nervous system (split across two sessions), endocrine, antimicrobials (split across four sessions because the bulk is here), chemotherapy and immunosuppressants, and finally miscellaneous classes including anti-parasitics and vaccines.
Five rules make this phase work. First, do not take notes — Pharmacology notes in a 45-day plan are a form of procrastination. Second, use one source per class, not three. Third, write the class by hand, not by keyboard; retention per minute is meaningfully higher. Fourth, do the MCQs on the same day as the reading, not the next day. Fifth, never end a session on a failed question; always solve one more until you land a correct one, so your brain files the class with a positive retrieval signal.
Phase 2 — Integration (Days 21–35): PYQs and clinical vignettes
Phase 2 is where students either level up or quietly collapse. The temptation is to "revise" — to re-read the notes from Phase 1 because that feels familiar. Do not. Reading again is the most expensive way to learn something you almost already know.
Instead, the entire fifteen-day block runs on vignettes. Fifty MCQs per day. The ratio is: thirty drawn from previous-year style question banks across all classes (generated or curated), fifteen clinical-scenario vignettes from Medicine, Pediatrics, Psychiatry, and Obstetrics that tag a Pharmacology concept, and five hard questions you save for the next morning's warm-up.
The method matters as much as the volume. For each vignette, before you look at the options, answer three questions out loud: What is the clinical context? What mechanism is being tested? What drug class would I reach for first? This takes fifteen seconds per question and roughly doubles retention because it forces reasoning before recognition. Only then do you look at the options.
On Days 21, 28, and 35, you do a class-level audit. Pull all the questions you got wrong in the previous week. Group them by drug class. Whichever class has the most wrong answers is where your next session starts. Foundation gave you breadth; integration punishes shallow breadth; this audit keeps you honest.
You can now read our mechanism-based MCQ strategy guide for the specific patterns NBE rewards in vignettes. Start using its five-step solve flow during these fifteen days — it is designed for exactly this phase.
Mid-plan checkpoint. At the end of Day 35, you should be able to sit down with a fresh fifty-question Pharmacology set and score above 60% untimed. If you are below that, do not advance to Phase 3. Extend Phase 2 by three days and re-audit.
Phase 3 — Revision and mocks (Days 36–45): spaced recall plus two mini-mocks
The final ten days are not about learning anything new. They are about ensuring that what you already know survives exam-day stress. Three routines run in parallel.
Reverse-order class revision. Revise in the opposite sequence you studied. You studied autonomics first, so you revise them last. Classes learned earliest are the weakest by default — spaced-repetition research consistently shows that earlier material decays faster without reinforcement. This routine takes 90 minutes per day, one or two classes at a time.
Pharmacology-only mini-mocks on Day 40 and Day 44. Forty questions, 45 minutes, strict timing. After each mock, do not just check the score. Tag every wrong answer by error type: did you misidentify the class, confuse two drugs within the class, or know the drug but pick the wrong indication? The error-type breakdown tells you exactly what to fix in the remaining days.
Daily ADR and interaction deck. Twenty cards, ten minutes in the morning. You can build this as a spaced-repetition deck — our spaced-repetition guide for NEET PG shows the interval schedule that works inside a 10-day window. Prioritize the ADRs with a clinical signature: aplastic anemia from chloramphenicol, peripheral neuropathy from isoniazid, pulmonary fibrosis from amiodarone and bleomycin, gingival hyperplasia from phenytoin, cyclosporine, and nifedipine, dry cough from ACE inhibitors.
Exam-day morning protocol. You do not learn anything the morning of the exam. You run two rituals. Flip through your ADR deck once. Read your own Phase 2 audit notes — the class you missed most often. Those are the classes your brain is primed to fail on under time pressure; ten minutes of reinforcement is worth more than a chapter.
High-yield drug classes that return every year
Across recent NEET PG papers and their close cousins, a small set of drug classes accounts for a disproportionate share of Pharmacology marks. The list below is not a shortcut — you still need to cover every system — but these classes repay extra attention because NBE returns to them with predictable framings.
For each of these, have ready — without looking anything up — the mechanism, three flagship drugs, one drug-of-choice indication, and one classical adverse effect. That is twelve data points per class, a hundred and twenty across the top ten.
The six trap patterns that lose students easy marks
NBE Pharmacology questions rarely test what you think they test. The framings below are recurring and cost students marks that they actually had the knowledge for.
The prodrug trap. The stem describes a drug that must be metabolically activated — enalapril to enalaprilat, codeine to morphine, clopidogrel (primarily by CYP2C19) — and the distractors all look mechanistically correct but ignore the activation step. When you see a hepatic impairment stem, look for prodrugs first.
The CYP inducer/inhibitor flip. Rifampicin induces, ketoconazole inhibits; the stem asks what happens to plasma levels of a co-administered drug. Students know the direction and still pick the wrong option because the question is phrased as "will decrease efficacy of…" rather than "will decrease plasma level of…". Read the verb.
The MOA-but-not-indication swap. Two drugs in different classes may share a mechanism — both ACE inhibitors and ARBs reduce angiotensin-II effect — but the indications and ADRs diverge. Questions exploit this by asking you to pick the drug for a scenario where the mechanistic lookalike is the wrong answer (usually due to ADR profile or contraindication).
The pregnancy-category booby trap. Any stem that mentions a pregnant or planning-pregnancy patient is almost always testing teratogenicity, not primary indication. ACE inhibitors, warfarin, tetracyclines, methotrexate, valproate, isotretinoin, lithium — memorize the full no-go list.
The dose-dependent ADR trick. Paracetamol is safe at therapeutic dose and hepatotoxic at overdose; amiodarone has a milder acute profile but causes pulmonary fibrosis, thyroid dysfunction, and hepatotoxicity with cumulative use; gentamicin is dose- and duration-dependent nephrotoxic and ototoxic. The stem anchors on duration or dose. Read both.
The newer-drug substitution. NBE has shifted toward direct oral anticoagulants, SGLT2 inhibitors, GLP-1 agonists, and newer monoclonals. Stems now test indications and ADRs for drugs that were not in older textbooks. Keep a rolling list of post-2020 additions and drill them in Phase 2.
The honest timetable: hours per day and what to drop
The plan assumes five focused hours per day on Pharmacology alone, with a Sunday half-day for revision. Below that, you can still make progress but your Phase 3 will feel rushed. Above seven, you are almost certainly trading other subjects for diminishing Pharmacology returns.
A realistic daily shape for a final-year intern: Pharmacology for three hours in the morning (core study plus recall), Medicine or Surgery for two hours after a break, a ninety-minute afternoon block of Pharmacology MCQs, and an evening split between one minor subject and revision of the morning's class. Rest days are real rest — not "light" study. Memory consolidates during downtime.
What to drop for the next 45 days: passive video content beyond 30 minutes per day, social reading on prep forums, and any coaching test series whose explanations you do not trust. Your time is too scarce to debug bad explanations. Stick to sources whose explanations teach mechanism.
Start your first Foundation session today. If you wait until tomorrow, you are already at Day 44.

Frequently asked questions
Is 45 days enough to master Pharmacology for NEET PG 2026?
Yes, if the 45 days are disciplined. The subject is modular, and mechanism-based study compounds quickly. The common failure is treating it as 45 days of leisurely coverage when it is actually 20 days of foundation, 15 days of pattern drill, and 10 days of recall maintenance. Protect the phase boundaries and the window is enough.
How many hours per day should I give Pharmacology in these 45 days?
Five focused hours daily is the working assumption. Four hours is survivable if you are disciplined about MCQ volume. Below four hours, the Phase 2 vignette drill collapses and you will enter Phase 3 undercooked. More than seven hours on Pharmacology means other subjects are starving — that is a planning error, not dedication.
Should I use Katzung, Tripathi, or only high-yield notes in a 45-day window?
Use Tripathi as your default Indian-context text and Katzung for mechanism depth when a concept does not click. Do not read either cover-to-cover in this window. Use the index. High-yield notes are fine as a revision layer in Phase 3 but are too thin to serve as the only source during Phase 1.
Which Pharmacology topics appear most often in NEET PG?
Autonomic pharmacology, cardiovascular drugs, antimicrobials, antiepileptics, and chemotherapy reliably dominate recent papers. Endocrine drugs, anticoagulants, and antipsychotics appear most years. Rare classes such as anti-parasitics still appear but with lower frequency. Prioritize the first cluster; do not neglect the second.
How many Pharmacology MCQs should I solve daily?
Ten per day in Phase 1, fifty per day in Phase 2, and forty questions per mock on Days 40 and 44 in Phase 3. Across 45 days that is roughly five hundred class-focused questions and another two hundred vignette-style questions — enough to stabilize pattern recognition for the exam.
What is the single biggest mistake students make with Pharmacology in the last 45 days?
Re-reading instead of drilling. Phase 2 is the fork in the road: students who keep re-reading notes feel productive but score the same in the mock as they did on Day 20. Students who switch to vignette drilling see measurable score improvement by Day 30. Active retrieval beats re-exposure.
Do I need to memorize every ADR, or only the boxed ones?
Prioritize ADRs with clinical signatures — the ones where knowing the ADR lets you reverse-engineer the drug from the vignette. Pulmonary fibrosis suggests amiodarone or bleomycin; gingival hyperplasia suggests phenytoin, cyclosporine, or nifedipine (the classic "PCN" triad). Boxed warnings deserve coverage but are fewer in number than signature ADRs and rarely appear as first-order questions.
How do I handle autonomic pharmacology — the part everyone says is confusing?
Draw the receptor map once, by hand, and keep re-drawing it daily in Phase 1. Alpha-1, alpha-2, beta-1, beta-2, beta-3, M1 through M5, and nicotinic Nm/Nn — their location, primary effect, and one selective agonist and antagonist each. Autonomic questions cluster around selectivity and reflex effects. The map, once reproducible from memory, answers most of them.
Is it worth learning drug interactions by CYP table, or is that overkill?
The CYP table is a teaching shortcut, not exhaustive. Memorize the dominant inducers (rifampicin, phenytoin, carbamazepine, phenobarbitone, chronic alcohol) and inhibitors (ketoconazole, erythromycin, ritonavir, isoniazid, grapefruit juice) plus the clinically relevant substrates (warfarin, oral contraceptives, phenytoin, theophylline). Beyond that is diminishing returns in a 45-day window.
Should I study Pharmacology alongside Medicine, or keep them separate?
Separate during Phase 1 foundation work, integrated from Phase 2 onward. In Phase 1 you need clean mechanism encoding without Medicine's clinical noise. Once the foundation is stable, Medicine vignettes become the ideal vehicle for Pharmacology recall — a hypertension vignette tests both drug mechanism and Medicine guidelines simultaneously.
How should my revision change in the final 10 days?
Reverse the order, compress the volume, and increase timed drilling. Earliest-studied classes need the most revision time because they have decayed most. Stop using your Phase 1 notes in Phase 3 — they are too long. Use class-by-class one-page summaries you wrote yourself, or your Phase 2 audit notes.
Can AI tools help me cram Pharmacology faster, and where do they go wrong?
AI tutors accelerate mechanism explanation and generate endless practice vignettes, which is exactly what Phase 2 demands. Where they go wrong is in specifics: drug-of-choice recommendations that lag current guidelines, dosage claims, and niche trials. Trust AI for mechanism, use it for vignette volume, and verify every specific recommendation against a textbook. Start with our free AI-graded practice →
