How to Study the AMH for OPRA and Intern Exams: A Practical Guide

The Australian Medicines Handbook (AMH) is arguably the single most important reference you'll use in Australian pharmacy. It's tested in OPRA, used in the open-book Intern Written Exam, and relied on daily in practice.

But owning a copy and knowing how to use it effectively are different things. This guide is about the second part.

Why the AMH Matters for Exams

For OPRA (Closed-Book)

The OPRA exam tests therapeutics and clinical decision-making in Australian practice. You cannot bring the AMH into the OPRA exam — it is entirely closed-book. No reference materials, no calculators, no notes.

However, studying from the AMH is still the best OPRA preparation strategy because the clinical content and drug information tested in OPRA aligns closely with how the AMH presents information. Studying from the AMH trains you to think in the structured way the exam tests.

Key implication for OPRA: You must memorise key drug information — doses, interactions, contraindications, counselling points — because you cannot look anything up during the exam. The AMH is your study tool, not your exam reference.

For the Intern Written Exam (Open-Book)

From January 2026, the Intern Written Exam is open-book. You can bring one original physical copy of the AMH. But with 75 questions in 120 minutes (96 seconds per question), you can't look up everything. The AMH helps with specific lookups — confirming a dose, checking an interaction — but only if you already know where to look.

Key implication for Intern Written: Speed of navigation is everything. You need to find information in under 30 seconds, or you'll run out of time. The AMH is your verification tool, not your learning tool.

Understanding AMH Structure

The AMH is organised by therapeutic class, not alphabetically by drug name. This is critical to understand:

Main Sections (Therapeutic Chapters)

The AMH contains approximately 20 main therapeutic chapters:

Chapter	Key Drug Classes
Cardiovascular	ACEi, ARBs, CCBs, beta-blockers, diuretics, anticoagulants, antiplatelets, statins
Respiratory	Beta-2 agonists, ICS, LAMA, LABA, leukotriene antagonists
Gastrointestinal	PPIs, H2 antagonists, laxatives, antiemetics, IBD drugs
Central Nervous System	Antidepressants, antipsychotics, anxiolytics, opioids, antiepileptics
Musculoskeletal	NSAIDs, paracetamol, gout drugs, DMARDs, biologics
Endocrine	Insulins, metformin, SGLT2i, GLP-1 RAs, thyroid drugs, corticosteroids
Infections	Penicillins, cephalosporins, macrolides, fluoroquinolones, antifungals, antivirals
Malignant Disease	Cytotoxics, targeted therapies, immunotherapies
Immunology	Vaccines, immunoglobulins, immunosuppressants
Nutrition and Blood	Iron, B12, folate, anticoagulants, antiplatelets
Dermatology	Topical corticosteroids, antifungals, retinoids, acne treatments
Eye, Ear, Nose	Glaucoma drops, antibiotic drops, nasal corticosteroids
Urogenital	BPH drugs, overactive bladder, UTI treatments, contraceptives

Within Each Chapter

Each chapter follows a consistent structure:

1. Practice Points — clinical context and guidelines summary
2. Drug Classes — grouped by mechanism or use
3. Individual Drug Monographs — detailed information per drug

Drug Monograph Structure — The Key Sections You Must Know

Every drug monograph follows the same format. Knowing this structure lets you find any piece of information instantly:

Section	What It Contains	Exam Relevance
Indications	Approved uses	What is this drug for?
Contraindications	When NOT to use	Safety questions
Precautions	Pregnancy, breastfeeding, renal/hepatic impairment	Dose adjustment, safety
Adverse effects	Common and serious side effects	Counselling, monitoring
Drug interactions	Clinically significant interactions	Drug-drug interaction questions
Dosing	Adult and paediatric doses	Calculation and prescribing questions
Patient counselling	Key points to tell the patient	Dispensing scenario questions
Practice points	Clinical pearls and practical advice	Clinical decision-making
Products available	Brand names, PBS status, formulations	Dispensing questions

Learn this structure inside-out. Once you know where information lives within a monograph, you can find any specific detail within seconds.

Navigation Strategies

1. Use the Index — But Know Its Limitations

The AMH has both a drug name index and a therapeutic index. For the open-book exam:

• Drug name index — fastest way to find a specific drug when you know the name
• Therapeutic index — useful when you know the condition but not the drug

Practice using both indexes until you can find a drug in under 10 seconds.

2. Learn the Colour Coding

Each therapeutic section has a distinct colour tab on the page edges. Learn these colours:

• You should be able to open directly to the cardiovascular section, the CNS section, or the infections section without checking the contents page
• This saves significant time in exam conditions
• Drill: Close the AMH, then open it directly to the infections chapter. Time yourself. Repeat until it takes less than 3 seconds.

3. Know the Appendices

The AMH appendices contain high-yield information that's often overlooked:

• Drug interactions tables — organised by drug, showing interactions and severity
• Drugs in pregnancy — categorisation and recommendations
• Drugs in breastfeeding — safety information
• Drugs in renal impairment — dose adjustment tables
• Drugs in hepatic impairment — adjustment guidance

These appendices answer many exam questions directly. For the open-book exam, flag these appendices prominently.

4. Navigation Speed Drills

Practise these timed exercises regularly:

Level 1 — Drug Lookup (target: <10 seconds):

• Find the monograph for metformin
• Find the monograph for warfarin
• Find the monograph for amoxicillin

Level 2 — Specific Information (target: <30 seconds):

• Find the maximum daily dose of paracetamol
• Find warfarin's INR target for atrial fibrillation
• Find metformin's dose adjustment in renal impairment

Level 3 — Clinical Scenarios (target: <45 seconds):

• A patient on lithium starts an NSAID — find the interaction
• A pregnant woman needs an antidepressant — find the pregnancy information for sertraline
• A patient with eGFR 25 is prescribed metformin — find the renal dosing guidance

OPRA Strategy: What to Memorise from the AMH

Since OPRA is closed-book, you need to internalise key AMH content. Focus on memorising:

Must-Memorise Drug Information

1. First-line treatments for common conditions (e.g., first-line antihypertensive, first-line antibiotic for UTI)
2. Key dose ranges for high-frequency drugs (not exact to the microgram, but the right ballpark)
3. Critical contraindications — the ones that cause harm (e.g., methotrexate in pregnancy, ACEi in bilateral renal artery stenosis)
4. Major drug interactions — the clinically dangerous ones (warfarin + NSAIDs, lithium + thiazides, methotrexate + trimethoprim)
5. Essential counselling points — what patients must be told (e.g., take on empty stomach, avoid grapefruit, don't stop suddenly)
6. Monitoring requirements — which drugs need blood tests and why (INR for warfarin, lithium levels, thyroid function on amiodarone)

High-Yield Drug Groups for OPRA

These drug groups appear most frequently in OPRA questions:

• Anticoagulants: Warfarin (INR targets, interactions), DOACs (renal dosing, reversal)
• Diabetes medications: Metformin (renal), sulfonylureas (hypo risk), SGLT2i (DKA risk), insulin types
• Antibiotics: First-line for UTI, pneumonia, cellulitis, otitis media
• Cardiovascular: ACEi/ARBs (cough, hyperkalaemia), statins, antiplatelets
• CNS: SSRIs (serotonin syndrome), opioids (respiratory depression), benzodiazepines (dependence)
• Respiratory: Asthma step therapy, COPD inhalers, ICS vs SABA

Intern Written Exam Strategy: Tabbing and Annotation

Tabbing Strategy

For the open-book exam, you're allowed small sticky flags (max 12mm × 44mm). Use them strategically:

Essential tabs (do these first):

1. Start of each major therapeutic chapter (cardiovascular, CNS, infections, endocrine)
2. Drug interactions appendix
3. Renal dosing appendix
4. Pregnancy appendix
5. Commonly tested drugs: warfarin, metformin, lithium, digoxin, phenytoin, amiodarone

Colour-code your tabs:

• Red — high-yield drug monographs (drugs you know will be tested)
• Blue — appendices
• Green — therapeutic chapter starts

Limit your tabs: Aim for 20–30 maximum. More than 30 tabs defeats the purpose — you can't distinguish between them quickly.

Highlighting Rules

• Highlight sparingly — if everything is highlighted, nothing stands out
• Use a colour system:
  • Yellow — doses (the number you need to verify)
  • Pink — contraindications (the "do NOT use" information)
  • Green — key interactions (the combinations to watch for)
• Focus on facts you frequently forget or need to verify under time pressure

What NOT to Do

• Don't write extensive notes in margins (this may not be permitted)
• Don't attach loose pages or inserts
• Don't flag every page — it defeats the purpose
• Don't rely on the AMH as your primary learning tool in the exam — it's for verification only

High-Yield Sections for Pharmacy Exams

Based on exam content weighting and frequency of clinical questions, prioritise these areas:

Tier 1: Must Know Thoroughly

• Cardiovascular — antihypertensives (ACEi, ARBs, CCBs, diuretics), anticoagulants (warfarin, DOACs), antiplatelets, statins, heart failure drugs
• Endocrine — diabetes medications (metformin, sulfonylureas, SGLT2i, GLP-1 RAs, insulin), thyroid drugs, corticosteroids
• Infections — antibiotics (know first-line for common infections), antifungals, antivirals
• CNS — antidepressants (SSRIs, SNRIs, TCAs), antipsychotics, anxiolytics, opioid analgesics, antiepileptics

Tier 2: Know Well

• Respiratory — asthma/COPD inhalers, preventer vs reliever, step therapy
• Gastrointestinal — PPIs, H2 antagonists, laxatives, antiemetics
• Musculoskeletal — NSAIDs, paracetamol, gout medications, DMARDs
• Immunology — vaccines and immunoglobulins

Tier 3: Know the Basics

• Dermatology — topical corticosteroid potency, antifungals, acne treatments
• Eye/Ear — glaucoma drops, antibiotic eye drops
• Urogenital — BPH medications, UTI treatments, contraceptives

AMH vs Other References

AMH vs Therapeutic Guidelines (eTG)

• AMH focuses on drug-level detail: doses, interactions, adverse effects, counselling
• eTG (available at tg.org.au) focuses on condition-level management: which drug to choose first, when to escalate, treatment algorithms
• For exams, you need both knowledge bases. Study eTG for clinical decision-making, AMH for drug-specific details
• Only the AMH can be brought into the open-book exam

AMH vs MIMS

• AMH is independent, evidence-based, and funded by subscriptions
• MIMS is commercially funded and includes product information
• AMH is the exam standard. Use AMH.

AMH vs Product Information (PI)

• PI is the TGA-approved document for each brand
• AMH synthesises PI information with clinical evidence and practice guidance
• AMH is more clinically useful; PI is the legal reference

AMH Online vs AMH Print

• AMH Online (amhonline.amh.net.au) is ideal for studying — searchable, always current, hyperlinked
• AMH Print is what you bring to the exam — practise with the physical book
• Study with online, practise navigation with print

Practice Exercises

Exercise 1: Speed Drills

Set a timer. Find the following information in your AMH as fast as possible:

1. Maximum daily dose of paracetamol in an adult
2. Warfarin's INR target for atrial fibrillation
3. First-line antibiotic for uncomplicated UTI
4. Metformin dose adjustment in renal impairment
5. Common drug interactions with lithium
6. Amlodipine maximum dose
7. Prednisolone dose for acute asthma in adults
8. Digoxin therapeutic range

Target: Under 30 seconds per lookup. If it takes longer, you need more practice.

Exercise 2: Monograph Familiarity

Pick 5 drugs. For each, without looking, write down:

• Class and mechanism
• Main indication
• Key contraindication
• Most important drug interaction
• Essential counselling point

Then verify against the AMH. This identifies knowledge gaps.

Exercise 3: Clinical Scenarios

Present yourself with clinical scenarios and use the AMH to confirm your answers:

• "A patient on warfarin is prescribed fluconazole. What happens?"
• "A diabetic patient has an eGFR of 25. Can they continue metformin?"
• "A pregnant woman needs an antidepressant. What are the options?"
• "A patient on an ACE inhibitor develops a dry cough. What do you recommend?"
• "A patient is started on amiodarone. What monitoring is required?"

This trains exam-style thinking with AMH reference.

Exam Day Strategy

For the Open-Book Intern Written Exam

1. Answer what you know first — don't open the AMH for questions you can answer from memory
2. Mark and move — if a question needs a lookup, mark it and come back
3. Use the index efficiently — know whether to search by drug name or therapeutic class
4. Verify, don't learn — the AMH is for confirming your answer, not for finding it from scratch
5. Time check at question 25 and 50 — you should be at 40 minutes and 80 minutes respectively
6. Use your tabs — go directly to flagged sections rather than flipping through pages

For OPRA (Closed Book)

7. Study the AMH content so you internalise the information — not just recognise it, but recall it
8. Focus on clinical decision-making sections and practice points
9. Know dose ranges for high-frequency drugs rather than exact figures
10. Understand drug interactions conceptually, not just as memorised pairs (e.g., understand WHY warfarin + NSAIDs is dangerous, not just that it is)

Key Takeaways

1. Learn the AMH structure — therapeutic chapters, monograph format, appendices
2. Practice navigation speed — index use, colour tabs, appendix location
3. OPRA is closed-book — memorise key drug information; use the AMH as your study source
4. Intern Written is open-book — focus on navigation speed and verification, not learning during the exam
5. Prioritise Tier 1 sections — cardiovascular, endocrine, infections, CNS
6. Highlight and flag strategically — less is more, use a colour system, limit to 20–30 tabs
7. Use the AMH to verify, not to learn during the open-book exam
8. Do timed practice lookups — 30 seconds per item is your target
