CSB601 Introduction to Clinical Therapeutics for Health

How CSB601 is assessed

The Semester 2, 2026 assessment overview lists Assessment 1 at 40% across three parts and the final examination at 60%, totalling 100%. The practice quizzes in Weeks 3, 4, 6 and 7 are formative and carry no marks. The peer survey task page gives both Monday and Friday of Week 12 as the deadline, so check the Canvas assignment for the time that applies to you.

What CSB601 covers

Eleven chapters follow the unit from Quality Use of Medicines and pharmacology foundations through each therapeutic week to the patient case method.

Depending on scope of practice, a health practitioner may prescribe, dispense, administer or review medicines, and the unit argues that each of those roles must be grounded in pharmacology, clinical therapeutics and Quality Use of Medicines thinking.

It is taught as an interprofessional unit, so students from different health disciplines work through the same patients together and learn what each profession contributes.

How the semester is organised

The first two weeks build the toolkit: Quality Use of Medicines, the evidence based medicines information resources, pharmacokinetics, pharmacodynamics, drug interactions and the special considerations for older adults and for pregnancy and breastfeeding.

Weeks 3 to 8 then take one therapeutic area at a time: depression, bipolar disorder, anxiety and sleep; hypertension, dyslipidaemia and heart failure; arrhythmias, anticoagulants and antiplatelets; diabetes; asthma and smoking cessation; and pain, NSAIDs, osteoarthritis and rheumatoid arthritis.

Week 9 is a drop in week for the group case, Weeks 10 and 11 cover allergies and antibiotics and then complementary and precision medicines, and Week 12 is set aside for revision.

How it is assessed

Assessment 1 is worth 40% in total: a group patient case study worth 30%, an individual interprofessional reflection worth 5% and a peer assessment survey worth 5%.

Assessment 2 is a closed book, invigilated final examination worth 60%, sat on campus in the central examination period.

Four practice quizzes run through the semester for feedback only and do not count towards the grade.

How to use this guide

Each chapter maps the ideas of one week, works an original patient case and ends with practice questions in the multiple choice and short answer styles the examination uses. Start with Chapters 1 to 3 if pharmacology feels shaky, because every later week assumes them.

Use Chapter 11 while your group drafts the case study, and return to it before the examination, because the short answer questions reward the same habit of naming a problem, its cause in the patient and the action that follows.

Key terms

Quality Use of Medicines

Quality Use of Medicines is the central objective of Australia's National Medicines Policy, concerned with selecting management options wisely, choosing suitable medicines and using them safely and effectively.

National Medicines Policy

The National Medicines Policy is the Australian framework that links timely access to medicines, their quality and safety, their quality use and a responsible medicines industry.

Pharmacokinetics

Pharmacokinetics describes what the body does to a medicine: its absorption, distribution, metabolism and elimination over time.

Pharmacodynamics

Pharmacodynamics describes what a medicine does to the body, including its receptor actions and the relationship between concentration and effect.

Steady State

Steady state is the plateau reached with regular dosing when the amount of drug eliminated between doses equals the amount given.

Potency

Potency is the dose or concentration of a medicine needed to produce half of its maximum effect.

Polypharmacy

Polypharmacy is the regular use of multiple medicines, commonly defined as five or more, which raises the risk of interactions and adverse effects.

Medication-Related Problem

A medication-related problem is an event or circumstance involving drug therapy that interferes, or could interfere, with the outcome a patient needs.

Best Possible Medication History

A Best Possible Medication History is a medicines list built from a structured patient interview and at least one other reliable source.

Serotonin Toxicity

Serotonin toxicity is a potentially serious reaction caused by excess serotonergic activity, often when two serotonergic medicines are combined.

Anticoagulant

An anticoagulant is a medicine that interferes with the coagulation cascade and fibrin formation, reducing the formation of clots.

Antiplatelet

An antiplatelet is a medicine that reduces platelet activation and aggregation, mainly protecting against arterial thrombosis.

Interprofessional Collaboration

Interprofessional collaboration is shared work by practitioners from different health disciplines who plan and review a patient's care together.

CSB601 FAQ

Questions students ask in each CSB601 chapter

Do I need to memorise every Poisons Standard schedule?

Ten schedules exist, but workshop activities concentrate on unscheduled products and Schedules 2, 3, 4 and 8 when you classify real packs. Be able to name those four confidently, recognise Schedule 8 as controlled drugs and Schedule 4 as prescription only, and know that the standard also covers labelling, storage and disposal of poisons across jurisdictions. Chapter 01 · Quality Use of Medicines and Medicines Information

Do I have to calculate doses from half-life in this unit?

The pharmacokinetics lecture states that regimen calculations were not worked through and points students to drug monographs and dosing nomograms instead. Prepare to reason about direction and timing: which parameter changed, whether levels rise or fall, and roughly how many half-lives the change takes to settle. Simple multiplication of a half-life by four or five is the most arithmetic you should expect to use. Chapter 02 · Pharmacokinetics and Pharmacodynamics

If a database labels an interaction as severe, must one of the medicines be stopped?

Not necessarily. A severe rating is a prompt to think: assess the individual risk, decide what to monitor, and compare safer alternatives. Many flagged combinations continue with closer monitoring or a dose change. Check whether other references agree on the rating, because eMIMSelite, AusDI and AMH may describe the same pair differently. Chapter 03 · Drug Interactions, Older Adults and Pregnancy

How long should I tell a patient to wait before deciding an antidepressant has failed?

Lecture material gives early improvement at one to two weeks, a meaningful response at three to four and full effect by four to six, occasionally eight. Workshop answers suggest about four weeks on one agent, with a dose increase considered before switching when the response is partial. Warn the patient that agitation or poor sleep can appear first, and arrange follow-up rather than an early change of drug. Chapter 04 · Depression, Bipolar Disorder, Anxiety and Sleep

Is a thiazide only a first choice for people aged 65 and over?

Teaching materials differ here. The 2023 hypertension lecture lists a low-dose thiazide as a first consideration for people 65 or older, whereas the 2026 workshop answer key places thiazide and thiazide-like diuretics among first-line options with no age limit. In an exam answer, give the full class list and mention the lecture's age qualifier so either reading is covered. Chapter 05 · Hypertension and Dyslipidaemia

Why are beta blockers used in heart failure if they slow the heart?

Long-term sympathetic overdrive speeds the heart, raises oxygen demand and drives arrhythmias and progressive ventricular damage. Selected beta blockers counter this, improving ventricular function, admissions and survival in reduced ejection fraction. Because early doses can briefly worsen symptoms or lower blood pressure, they start only in stable, euvolaemic patients at a very low dose that rises slowly. Chapter 06 · Heart Failure and Coronary Heart Disease

Why is digoxin not used to convert atrial fibrillation back to normal rhythm?

Digoxin slows conduction through the AV node by increasing vagal tone, which lowers the ventricular rate at rest, but it does not convert AF to sinus rhythm or stop it returning after cardioversion. It also works poorly during exercise, when sympathetic tone is high, so it suits patients at rest and those who also have heart failure. Chapter 07 · Atrial Fibrillation, Anticoagulants and Antiplatelets

Why does a sulfonylurea cause hypoglycaemia when metformin alone does not?

Sulfonylureas stimulate insulin secretion regardless of the blood glucose level, so a missed meal or extra exercise leaves insulin working with little glucose available. Metformin reduces liver glucose production and improves sensitivity without forcing insulin release. In older adults, guidance on medicines to use with caution names gliclazide, glipizide and glibenclamide for exactly this reason, so a falls or confusion history should prompt a review. Chapter 08 · Diabetes Pharmacotherapy and Adherence

Why is salbutamol alone no longer recommended for adults with mild asthma?

A short-acting beta2 agonist relieves bronchospasm but leaves the inflammation untreated, and reliance on it alone is associated with more severe exacerbations, admissions and deaths. Guidance therefore includes an inhaled corticosteroid from the outset, most often through as-needed budesonide-formoterol. That combination gives fast bronchodilation from formoterol and anti-inflammatory treatment from budesonide every time symptoms prompt a dose. Chapter 09 · Asthma and Smoking Cessation

Why is paracetamol still recommended if it only reduces pain a little?

Most analgesics in clinical use reduce pain intensity by roughly 30 percent, and none abolishes pain outright. Paracetamol has a strong safety record at recommended doses, is suitable in pregnancy and breastfeeding, and performs better when taken on a schedule. Its weakness is inflammation, which is why NSAIDs are reserved for pain with an inflammatory driver. Chapter 10 · Pain, NSAIDs, Osteoarthritis and Rheumatoid Arthritis

How many medication-related problems should our group write up?

The A1 template shows four worked problem blocks and allows up to five if the word count permits. Quality beats quantity: each block needs the problem detail, options, the chosen decision, a short context fit and a collaboration plan, and the rubric rewards prioritising and critically evaluating problems more than listing extra ones. Chapter 11 · Medication History and Patient Case Assessment

How to study for the exam

Build the toolkit first. Before the therapeutic weeks pile up, make sure you can explain half-life and steady state, potency and efficacy, and the difference between pharmacokinetic and pharmacodynamic interactions, because nearly every later question leans on them.

For each therapeutic week, keep a one page table with four columns: drug class, how it works, the adverse effect most likely to be examined, and what the patient must be told or monitored. Say the rows aloud from memory, then check them against your notes and correct the first mistake you made.

Each week, invent one short patient and write a four line answer: the problem, the patient fact that causes it, the change you would recommend and the follow-up. Use the formative quizzes as timed rehearsals for the multiple choice section, and when you miss an item, write down the one fact that would have rescued you.

In the final fortnight, rotate through the chapters by body system, reserve time for the Week 10 and 11 topics from the unit's own materials, and finish with two timed mixed practice sets.
