What is in it
What gout is Who gets it, the numbers, and the four stages from high urate to tophi.
Where urate comes from Purines, xanthine oxidase, and how the kidney and gut handle urate.
Crystals vs serum urate Why crystals form above about 6.8 mg/dL and dissolve below the target.
A flare, hour by hour From a shed crystal to the NLRP3 inflammasome, interleukin-1β and neutrophils, then resolution.
Colchicine inside the cell From the pill to the neutrophil to the microtubule.
Treating a flare Colchicine, NSAIDs, glucocorticoids, IL-1 blockers and ice.
Colchicine dosing and safety Published doses, kidney function and drug interactions.
How urate-lowering drugs work Allopurinol, febuxostat, uricosurics and pegloticase.
Treat to target Titrating to below 6 mg/dL, and why flares rise in the first months.
Safety of urate-lowering drugs HLA-B*58:01, the CARES and FAST trials, interactions.
Diagnosis and the ACR/EULAR score Crystals under polarised light, imaging, and the 2015 classification calculator.
The differential Calcium pyrophosphate crystal arthritis, septic arthritis, cellulitis and others.
Gout, kidneys and heart Chronic kidney disease, stones, blood pressure and cardiovascular risk.
Living with gout Diet, alcohol, weight, other medicines and a flare plan.
Nursing care Assessment, giving the medicines, teaching and documentation.
Toward a cure Dissolving crystals for good, and the research pipeline.
History and people From podagra to polarised light and allopurinol.
Flashcards, quiz and glossary Revision for students.
Sources Every reference behind the app.
Part 2 · Treating a flare
Colchicine inside the cell
Colchicine, from the autumn crocus, is one of three first-line drugs for a gout flare. Follow one dose from the mouth into a white cell, where it takes apart the microtubule scaffolding that the crystal alarm needs. Seven scenes, one timeline.

Schematic, not to scale.
Related guide: colchicine is approved for gout and for familial Mediterranean fever (FMF), and gout is its best-established rheumatic use. 369 The FMF Companion follows the same dose into a neutrophil in that disease, where a different inflammasome is involved.
