A pharmacologically challenging patient case works best when it centres on one interaction between two drugs, explained through mechanism, pharmacokinetics and consequence for the patient. For MD3005 you have only a short word count, so choose a case where the “why” is clear, name the two drugs early, and spend most of your words on how they affect each other.

If you want a second pair of eyes on a short pharmacology draft, our nursing assignment help page sets out how we support healthcare students.

What the assessment is really asking

The MD3005 pharmacology written assignment at University College Cork asks you to pick a patient case that is hard to manage pharmacologically, usually because of polypharmacy. You then analyse two relevant drugs and explain why the combination caused difficulty. According to the question page the assignment is worth 30 marks, has a 500-word limit and is submitted as a Word file through Canvas. Check your own module brief for the final details, including the deadline.

Notice what is not being asked. It is not a literature review, and it is not a clinical history. The brief wants pharmacological reasoning: what each drug does, what the body does to each drug, and what happens when they meet. Management advice is optional and should be brief.

The brief also says to prefer uncommon, challenging cases over textbook ones, and to write in full text rather than bullet points. Both points shape how you plan.

Suggested word split

The brief does not give marks per section, so treat the table below as a suggestion only and adjust it to your own guidance.

A step-by-step plan

1. Pick the case early. The brief says to confirm your choice with the module coordinator by the end of week 1, and that a case will be supplied if you cannot find one.
2. Write one sentence stating the interaction you will argue, for example that drug A slows the clearance of drug B.
3. List the key facts for each drug: target, absorption, protein binding, route of metabolism, route of excretion, main adverse effects.
4. Decide which facts matter to the interaction and cut the rest.
5. Find two or three credible sources per drug, ideally a summary of product characteristics and a textbook or peer-reviewed paper.
6. Draft in full sentences, then trim to the limit.
7. Check every in-text citation against your bibliography.

For a worked illustration of this plan, see our reference sample for the MD3005 pharmacology case, for study use only. It uses a fictional case and shows how 500 words can be divided.

Choosing the case and the two drugs

Pick a case with a clear mechanism

The best cases are those where you can explain the interaction in a few sentences. An enzyme inhibitor raising the level of a narrow-therapeutic-index drug is a classic structure. So is additive central nervous system depression from a sedative plus another depressant. If you cannot state the mechanism in plain words, the case is probably too tangled for 500 words.

The brief includes a short example about a prescribed sedative taken with alcohol. It is useful as a model of how little case detail you need, but the guidance asks for less textbook cases. Think about situations from your own practice, or a case you have read about in a published case report.

Stay with two drugs

Many real patients take six or eight medicines. Resist the urge to discuss them all. Name the others in one clause if they matter, then analyse only the two the brief asks for.

Section-by-section guidance

The case description

Give age band, relevant conditions, the drugs involved and what happened. Leave out names, places and anything identifying. If the case comes from your own practice, anonymise it fully. Write it in the past tense and keep it short.

Each drug analysis

For every drug, cover pharmacodynamics, then the four pharmacokinetic steps of absorption, distribution, metabolism and excretion, then relevant adverse effects. The word “relevant” matters. If the interaction depends on a particular liver enzyme, name it. If protein binding matters, give the approximate percentage. A figure that supports your argument earns more than three that do not.

Aim for balance. Giving one drug twice the space of the other looks like you ran out of time.

The interaction

This is the heart of the answer. Say whether the interaction is pharmacokinetic, pharmacodynamic or both, explain the mechanism, and say what the effect on the patient is. Where the mechanism is debated, say so. Admitting that evidence is mixed reads as mature analysis rather than weakness.

Use at least one piece of evidence, such as a cohort study, a systematic review or the interaction section of a product’s official prescribing information.

Implications and management

Describe how the patient’s drug effect changed and what harm followed or was avoided. If you add a management suggestion, keep it to pharmacological rationale, for example why monitoring a blood test or switching to a drug with less enzyme effect would help. The brief says explaining the challenge matters more than proposing a fix.

What a higher-scoring answer looks like

The stronger versions name the mechanism and the consequence. The weaker ones only state that something happened.

Mark-maximising checklist

• The two drugs are named in the first two or three sentences.
• Both drugs get pharmacodynamics, all four ADME steps and relevant adverse effects.
• The interaction takes the largest share of the words.
• Every paragraph is in full sentences, with no bullets.
• The case contains no identifying details.
• Claims are supported by credible sources, cited in your required style.
• The bibliography matches the in-text citations exactly.
• The file is named as the brief instructs.
• You are within the word limit, checked against your module rules on what counts towards it.

Common mistakes

• Writing a clinical case report. Vital signs, test results and a long timeline use up words that should go on pharmacology.
• Describing drugs separately and never joining them. The marks sit in the link between the two analyses.
• Using generic ADME. Saying a drug is “absorbed in the gut and excreted by the kidneys” says nothing specific. Give the detail that applies.
• Overclaiming certainty. If a mechanism is only partly understood, say that.
• Relying on websites. Use official prescribing information, textbooks and peer-reviewed journals.
• Letting management take over. It is optional and brief.
• Going over the limit. Trim background first, never the interaction.

Common student worries

Many students worry that 500 words is too short to show what they know. It is short, which is the point: the task tests selection as much as knowledge. Another worry is that a case from practice might identify a patient. Remove anything that could, and keep to the pharmacology. Others fear choosing a case that is too ordinary. An ordinary drug pair can still work if your analysis of the mechanism is precise and well evidenced.

If you are a paramedic student, the related paramedic pharmacology polypharmacy case question asks for a similar analysis, so its planning approach carries over. Students based in the south of Ireland can also read about assignment support for Cork students, and the page on case study help in Ireland covers case-based briefs more generally.

FAQs

How many drugs should I analyse?

The brief asks for two. You may mention others briefly if they affect the case, but the analysis should stay on two.

Can I use a case from my own placement or work?

The brief invites you to describe a case, and some versions refer to your professional past. Anonymise it completely and confirm your choice with the module coordinator, as the brief instructs.

Should I use bullet points to save words?

No. The brief asks for full text rather than bullet points, so use short, well-built paragraphs. A small summary table may be acceptable in some modules, but check with your coordinator first.

Do I have to suggest a treatment or management plan?

It is optional. If you include one, keep it to a brief pharmacological rationale. The explanation of why the combination was challenging carries more weight.

What sources are acceptable?

Use credible sources: official prescribing information, standard pharmacology textbooks and peer-reviewed articles. Follow the referencing style your module requires, and see our citation and referencing help if you want a refresher.

What happens if I cannot find a suitable case?

The brief says the module coordinator will supply one if you cannot find a suitable case, so raise it early rather than late.
