What PHA2022 covers
The path runs from Drug Targets, Receptors and Dose–Response through Drug Benefit, Harm and Society to Laboratory Evidence, Team Controversy and MCQ Reasoning.
Drug Targets, Receptors and Dose–Response
agonist · EC50 · therapeutic windowPharmacodynamics asks what a drug does to a biological system and how the measured response changes with concentration. Begin with the target: receptor, enzyme, transporter, ion channel or other molecule. Binding alone is not the final effect.
- agonist
- EC50
- therapeutic window
- connect molecular target engagement to graded and quantal responses using potency, efficacy and uncertainty correctly
- A concentration–response curve describes the measured system; it does not by itself establish clinical dose, benefit or safety.
Pharmacokinetics, Exposure and Dosing
bioavailability · clearance · half-lifePharmacokinetics describes how the body handles a drug through absorption, distribution, metabolism and excretion. The useful object is concentration over time in a defined compartment, not a list of four words.
- bioavailability
- clearance
- half-life
- reason from absorption, distribution, metabolism and excretion to concentration over time and dosing decisions
- Plasma concentration is a useful exposure measure but may not equal concentration at the effect site or determine response alone.
Drugs of Abuse, Tolerance and Dependence
tolerance · dependence · reinforcementDrugs of abuse are studied through pharmacology, learning, adaptation and context. Reward and reinforcement are related but not identical to subjective pleasure. A consequence reinforces a behaviour when it increases its future probability.
- tolerance
- dependence
- reinforcement
- explain repeated drug use through reward, adaptation, learning, withdrawal and context without moral or single-mechanism shortcuts
- Tolerance, dependence, harmful use and addiction overlap but are not interchangeable labels or moral judgements.
Drug Benefit, Harm and Society
absolute risk · relative risk · harm reductionDrug policy and public communication require translation from measured outcomes to population consequences. Begin with the decision: approve, restrict, subsidise, warn, monitor, decriminalise or provide harm reduction.
- absolute risk
- relative risk
- harm reduction
- evaluate drug-related claims across individual effect, population risk, regulation, equity and unintended consequence
- Evidence of average effect does not decide policy without population, distribution, feasibility and value judgements.
Drug Development and Evidence Translation
preclinical evidence · randomisation · surrogate endpointDrug development is a sequence of decisions under uncertainty rather than a guaranteed pipeline. Target rationale links a biological process to a disease mechanism and proposes an intervention point. Assays test engagement and downstream response.
- preclinical evidence
- randomisation
- surrogate endpoint
- trace a candidate from target rationale through preclinical and clinical evidence while separating safety, efficacy and generalisability
- Regulatory approval supports a defined benefit–risk decision for an indication; it does not prove universal superiority or absence of rare harm.
Laboratory Evidence, Team Controversy and MCQ Reasoning
positive control · replication · distractorLaboratory evidence begins with a protocol that another person can follow and a design that can answer the question. Record preparation, concentrations, volumes, timing, temperature, equipment settings and decision rules.
- positive control
- replication
- distractor
- turn experimental observations and contested drug claims into reproducible analysis, balanced communication and discriminating questions
- A polished team product or statistically significant assay is not sufficient without traceable contribution, appropriate controls and bounded translation.
The guide follows those connections instead of treating molecular action and society as unrelated halves.
The verified assessment structure is laboratory and workshop activities 30%, team assignment 25%, in-semester quizzes and tests 25%, and a 20% examination of 2 hours 10 minutes. The laboratory and workshop exercise component is a threshold hurdle.
The examination is not represented as a separate threshold hurdle in the current official structure.
Pharmacodynamic reasoning begins with target, concentration, transduction and measured response. Potency is horizontal position and efficacy is achievable response; neither determines safety alone. Antagonists, receptor reserve and adaptation change the curve in mechanism-specific ways.
Clinical decisions require exposure and benefit–harm evidence beyond an assay curve.
Pharmacokinetics supplies the time course. Bioavailability shapes systemic input, volume relates amount to measured concentration, and clearance relates concentration to elimination. Half-life and accumulation emerge from those parameters.
Dose adjustment should name whether loading, maintenance, interval or monitoring is being changed and why.
Repeated drug use brings pharmacology together with learning and context. Tolerance, dependence, sensitisation, reinforcement and withdrawal describe different processes. Abstinence can lower tolerance, conditioned cues can change response and social conditions shape exposure and access to care.
Mechanistic language replaces moral shorthand.
Societal evaluation translates relative and absolute risk, asks who receives benefit or harm, and considers implementation. Regulation changes incentives and can displace behaviour. Harm reduction targets preventable consequence under current conditions.
Evidence informs policy but does not silently choose values, equity weights or acceptable uncertainty.
Drug development narrows uncertainty from target rationale through preclinical and human evidence. Randomisation, concealment, blinding, comparators and meaningful endpoints determine efficacy claims.
Surrogate changes do not guarantee patient benefit, and approval for a defined indication does not prove universal superiority or eliminate rare harm.
Laboratory work makes the evidence path visible. Controls diagnose assay function, independent biological replicates determine the unit of inference and raw-to-processed data must be traceable.
Because the exercise component is a hurdle, preparation, safe participation, reproducibility and completion require early attention in live unit systems.
The team assignment asks for balanced communication about drug controversy. Balance means proportional representation of strong evidence, material harm, benefit, uncertainty and values—not equal time for unequal claims.
PeerWise item writing converts misconceptions into discriminating options and explanations.
All cases and calculations here are original study practice. They do not reproduce the examination, laboratory tasks, quiz bank, PeerWise submissions or team project.
Current dates, safety operations and adjustments remain controlled by Monash systems.
A practical study loop is target → exposure → response → evidence → context → decision. For each drug case, state dose and route, predict concentration over time, identify the measured effect, compare benefit and harm, and name what cannot be translated.
This loop connects every chapter.
Before submission or exam, audit units, scale and causal language. Concentration is not dose; binding is not benefit; association is not cause; statistical significance is not clinical importance; cell viability is not human safety; approval is not absence of uncertainty.
Correcting those category errors produces most of the course's high-value reasoning.
The final check is reversibility: name the observation that would change the chosen dose, mechanism, trial interpretation or policy recommendation. A review trigger may be unexpected accumulation, a reduced maximum, a patient-relevant null result, a displaced harm or a failed laboratory control.
Decisions become scientifically accountable when their update condition is written before confidence hardens.
