Colchicine is an alkaloid drug obtained from the autumn crocus plant (colchicum autumnale), which is used to treat or prevent gout attacks and FMF ( familial medditerannean fever). It is by no means a painkiller and should not be used to treat other causes of pain. Colchicine is classified as an anti-gout agent, which works by decreasing the natural process of swelling and lessening the accumulation of uric acid crystals that result in pain in the affected joints.
Each capsule consists of 0.6mg Colchicine and inactive ingredients listed below:
● Lactose anhydrous
● Silicon dioxide
● Magnesium stearate
● Sodium starch glycolate
● Microcrystalline cellulose
The ingredients making up the capsule shell are gelation, titanium dioxide, purified water, erythrosine, Quinoline yellow and Blue FCF.
The drug should be stored 20-25°C and protected from sunlight and moisture.
Colchicine is effective in treating gout due to its capability to block neutrophil-mediated inflammatory responses caused by monosodium urate crystals. The drug disrupts the polymerization of beta-tubulin into microtubules, therefore inhibiting the activation, degranulation and migration of neutrophils into the sites of infection.
The mean Cmax of the drug when given to healthy adults is 3ng/mL after single 0.6mg dose oral administration. Cytochrome P450 3A4 metabolises 16% of colchicine to 2- and 3- demethyl colchicine. The drug distribution is known to range between 5 to 8 L/kg.
