Gastrointestinal and Endocrine Pharmacology
Compare medicines affecting secretion, motility, nausea, glucose and endocrine function.
How to prepare for MRCEM Primary
Protect Anatomy and Physiology, which together form two-thirds of the paper, while retaining deliberate coverage of all four smaller categories and their official subcategories.
Core concepts
Concept 1
Antiemetics, acid suppression, motility and bowel medicines, insulin and glucose-lowering agents, corticosteroids, thyroid medicines and endocrine antidotes.
Exam cue: Name the structure, mechanism, organism, medicine action or evidence measure being tested.
Concept 2
Match receptor or biochemical target to therapeutic effect, adverse effect, interaction and emergency use.
Exam cue: Connect the recalled fact to one clinically relevant emergency-care consequence.
Concept 3
Recognise hypoglycaemia, adrenal suppression, electrolyte effects, QT risk and contraindications in acute illness.
Exam cue: Check units, direction, anatomical level, timing and the exact lead-in before selecting one answer.
Concept 4
Keep revision at the detailed applied basic-science level defined by the RCEM Basic Sciences Curriculum rather than drifting into higher clinical-management knowledge.
Risk pitfalls and guardrails
Selecting a medicine by class name without its mechanism, route, onset, organ clearance and patient-specific risk.
Guardrail: Do not select an answer because it is partly true; test it against every word of the lead-in.
Choosing an option that is partly plausible rather than the single option that is fully correct.
Guardrail: Do not select an answer because it is partly true; test it against every word of the lead-in.
Turning a basic-science item into a management question beyond the Primary remembering-and-understanding boundary.
Guardrail: Do not select an answer because it is partly true; test it against every word of the lead-in.
Memory anchors
Gastrointestinal and Endocrine Pharmacology: scope
Antiemetics, acid suppression, motility and bowel medicines, insulin and glucose-lowering agents, corticosteroids, thyroid medicines and endocrine antidotes.
Gastrointestinal and Endocrine Pharmacology: applied link
Match receptor or biochemical target to therapeutic effect, adverse effect, interaction and emergency use.
Gastrointestinal and Endocrine Pharmacology: safety boundary
Recognise hypoglycaemia, adrenal suppression, electrolyte effects, QT risk and contraindications in acute illness.
Gastrointestinal and Endocrine Pharmacology: common trap
Selecting a medicine by class name without its mechanism, route, onset, organ clearance and patient-specific risk.
Gastrointestinal and Endocrine Pharmacology: Primary sequence
Recall the underlying structure or mechanism, connect it to the emergency-care finding, exclude the main safety trap, then choose the single fully correct option.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
