In pharmacology, colchicine is a "major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (period disease)."[1]
Dosage
Acute gout attack
The UK National Library for Health recommends 0.5 mg two to four times a day.[2]
Thomson Healthcare recommends: Initially 1 to 1.2 milligrams, then one of the following until symptoms better or gastrointestinal drug toxicity (stomach pain, vomiting or diarrhea) occur:[3]
- 0.5 to 0.6 milligram every hour
- 1 to 1.2 milligrams every two hours. 0.5 mg every 2 hours has been used, but still causes consistent toxicity[4]
- 0.5 to 0.6 milligram every 2 to 3 hours
The maximum dose per attack is 4 to 8 milligrams total.
Other schedules: Regarding the best dose, 1.2 mg followed by 0.6 mg in 1 hour may be as effective as higher dose.[5]
To avoid drug toxicity, lower doses of colchicine (0.6 per day) have been used in combination with glucocorticoids.[6]
Prevention of gout
Clinical practice guidelines recommend 0.5 to 1.0 mg per day.[7]
Drug interactions
Colchicine is metabolized by the CYP3A4 isoenzyme of cytochrome P-450 and may interact with other durgs with similar metabolism.[8] Colchicine my also down regulate CYP2C9.[9]
Use in genetics and agriculture
Colchicine is used to induce polyploidy in plants.[10]
