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

The OPRA exam tests therapeutics and clinical decision-making in Australian practice. While you can't bring the AMH into the OPRA exam, the clinical content you need to know aligns closely with how the AMH presents drug information. Studying from the AMH trains you to think in the way the exam tests.

For the Intern Written Exam

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.

Understanding AMH Structure

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

Main Sections (Therapeutic Chapters)

• Cardiovascular
• Respiratory
• Gastrointestinal
• Central Nervous System
• Musculoskeletal
• Endocrine
• Infections and Infestations
• Malignant Disease
• Immunology
• Nutrition and Blood
• Dermatology
• Obstetrics and Gynaecology
• Eye, Ear, Nose and Oropharynx
• Urogenital

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

Every drug monograph follows the same format:

• Indications and uses
• Contraindications
• Precautions (including pregnancy, breastfeeding, hepatic/renal impairment)
• Adverse effects
• Drug interactions
• Dosing (adult and paediatric where applicable)
• Patient counselling
• Practice points
• Products available (brand names, PBS status)

Learn this structure. 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

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.

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

Highlighting and Flagging Strategy

For the open-book Intern Exam, you're allowed to highlight and use small sticky flags (max 12mm × 44mm). Here's how to use them strategically:

Highlighting Rules

• Highlight sparingly – if everything is highlighted, nothing stands out
• Use a system – one colour for doses, another for contraindications, a third for key interactions
• Focus on high-yield facts you frequently forget or look up

Flagging Strategy

• Flag the start of each major therapeutic chapter (saves navigating from the index)
• Flag specific high-yield pages you know you'll need: drug interactions appendix, renal dosing appendix, pregnancy appendix
• Flag commonly tested drugs: warfarin, metformin, lithium, digoxin, phenytoin, amiodarone
• Limit your flags – too many flags are useless. Aim for 20–30 maximum, not 200

What NOT to Do

• Don't write extensive notes in margins (not allowed)
• Don't attach loose pages or inserts
• Don't flag every page – it defeats the purpose

AMH vs Other References

AMH vs Therapeutic Guidelines (eTG)

• AMH focuses on drug-level detail: doses, interactions, adverse effects, counselling
• eTG 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

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

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

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?"

This trains exam-style thinking with AMH reference.

Exam Day Strategy

For the Open-Book Intern 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

For OPRA (Closed Book)

6. Study the AMH content so you internalise the information
7. Focus on clinical decision-making sections and practice points
8. Know dose ranges for high-frequency drugs rather than exact figures
9. Understand drug interactions conceptually, not just as memorised pairs

Key Takeaways

1. Learn the AMH structure – therapeutic chapters, monograph format, appendices
2. Practice navigation speed – index use, colour tabs, appendix location
3. Prioritise Tier 1 sections – cardiovascular, endocrine, infections, CNS
4. Highlight and flag strategically – less is more, use a colour system
5. Use the AMH to verify, not to learn during the open-book exam
6. Do timed practice lookups – 30 seconds per item is your target
7. Study AMH content for OPRA even though it's closed-book – the clinical thinking transfers directly
