Project brief from Sandton medical writers
The client was a medical writing team in Sandton preparing educational material for healthcare audiences, including clinicians and pharmacists. They needed a source-organised summary that pulled together core CYP450 background, common interaction themes, and careful wording that could support later drafting without turning the piece into a clinical recommendation sheet.
The brief was specific about tone and scope. It had to be factual, measured and easy to scan, with enough structure for a writer to find the relevant enzyme families, interaction patterns and terminology quickly. It also needed to suit South African readers, so the wording had to stay practical and clear for use across Cape Town, Johannesburg, Pretoria, Durban and Bloemfontein.
- Project type: source-organised scientific background summary
- Primary users: medical writers working on clinician and pharmacist material
- Focus: CYP450 enzyme families, drug-enzyme interactions and general pathway context
- Output style: balanced background notes, not promotional copy
What the brief allowed and what it did not
The main constraint was careful scientific restraint. The client did not want advice on dosing, diagnosis or treatment choices, and we were careful not to present any medicine as universally safe or unsuitable. We also avoided claims that would go beyond accepted general knowledge, because the summary was meant to inform a writing team not to replace clinical judgement.
Another constraint was format. The team wanted a source-led summary they could trust at a glance, with each section tied to a topic rather than a long narrative. That meant keeping the material organised around enzyme groups, common substrate and inhibitor examples at a general level, and the practical meaning of interactions in everyday clinical work. The language had to stay readable for non-specialists too, since the final material would be reviewed by mixed audiences.
- No personal medical advice
- No dosing advice
- No diagnosis or treatment instructions
- No unsupported figures, trials or clinical claims
- Readers directed to their own doctor or pharmacist for medicine-specific guidance
How we structured the summary
We supplied the summary in a source-organised format so the writing team could move quickly from background reading to drafting. The structure started with a plain explanation of what CYP450 enzymes do, then moved into common reasons they matter in medicine response, nutrient pathways and drug handling. We kept the scientific language careful and avoided overstatement, since CYP450 function varies by enzyme, by medicine and by person.
The document also included practical signposts for writers. These covered common interaction types, why enzyme inhibition and induction matter, and how genetic variation can shape enzyme activity. We did not present these as treatment rules. Instead, we set out the general principles that a medical writing team would need when preparing balanced education copy for pharmacists, clinicians and wellness practitioners.
- Clear heading hierarchy for quick scanning
- Topic-by-topic source grouping
- Plain language definitions for technical terms
- Notes on where caution is needed in public-facing wording
Working method and turnaround in weeks
The project ran over three weeks. In week one, we mapped the source set and agreed the scope with the Sandton team, including which enzyme families and interaction themes were in bounds. Week two focused on drafting and cross-checking the language so the summary stayed accurate, careful and usable for downstream writing. Week three was used for refinement, layout adjustments and final reference checking.
Because the client was working to an internal writing schedule, speed mattered but not at the cost of clarity. We kept the turnaround steady and practical, with each pass aimed at reducing ambiguity. That included trimming anything that read too strongly, tightening definitions and making sure the summary would still be useful if a pharmacist or clinician picked it up later in the process.
- Week 1: scoping and source mapping
- Week 2: drafting and fact checking
- Week 3: refinement and final handover
Key facts supplied to the writing team
The finished summary gave the client a reliable base for broader educational material. It covered the core role of CYP450 enzymes in drug metabolism, the meaning of inhibitor and inducer effects, and why genetic variation can help explain different responses to the same medicine. It also included a careful reminder that interaction interpretation depends on the full clinical picture, not on one pathway alone.
We also made sure the summary supported South African use. That meant keeping the terms accessible for practitioners working in busy urban settings and avoiding jargon that would slow the drafting team down. The material was not written as a patient handout. It was prepared as a working resource for medical writers who needed a solid foundation before they shaped final education content for their own audience, and that distinction mattered.
- Core enzyme families described at a general level
- Interaction themes explained in plain language
- Genetic variation covered without overclaiming
- Reference-ready wording for later drafting
What the client could use straight away
The main result was a cleaner drafting process. The Sandton team had a source-organised summary they could use to brief writers, check terminology and keep the project aligned with accepted science. That reduced back-and-forth during content development and helped the team keep a steady tone across sections that would later be used in educational outputs for healthcare professionals.
If we were doing the job again, we would keep the same structure and add a slightly earlier check-in on the intended reading level for the final audience. That helps us tune the level of detail before the writing stage begins. We would also keep the same focus on balance, because CYP450 material is easy to overstate if the science is not handled carefully. For medicine-specific questions, the final audience still needs to speak to their own doctor or pharmacist.
- Balanced background material for medical writers
- Cleaner handover from research to drafting
- Reduced risk of overstatement in final copy
- Useful for future literature review or briefing work
