For prophylaxis of gout flares, the recommended dosage of Colchicine capsules is 0.6 mg once or twice daily. The maximum dose is 1.2 mg per day. Colchicine capsules are administered orally, without regard to meals.

Inhibition of the polymerization of brain tubulin was evaluated. Solution of compound in DMSO in serial dilutions was prepared. Reaction mixture contained 0.25 mg of tubulin, 1.0 M monosodium glutamate and approptiate drug concentrations. The reaction mixtures were incubated at 37 °C for 15 min to allow slow binding drugs like colchicine to bind to the tubulin. The reaction mixtures were then chilled on ice, and the polymerization reaction was followed turbidimetrically for 20 min. Polymer formation was confirmed by evaluation of depolymerization at 0°C. Extent of inhibition of polymerization at 20 min in drug-treated samples was always calculated by comparing them to a pair of drug-free samples in each experimental set.
