Active Ingredients:
Allopurinol
Therapeutic actions:
Colchicine inhibits microtubule polymerization by binding to tubulin, one of the main constituents of microtubules. Availability of tubulin is essential to mitosis, and therefore colchicine effectively functions as a "mitotic poison" or spindle poison. Since one of the defining characteristics of cancer cells is the significantly increased rate of mitosis, this means that cancer cells are significantly more vulnerable to colchicine poisoning than the normal cells. However, the therapeutic value of colchicine against cancer is (as is typical with chemotherapy agents) limited by its toxicity against normal cells.
Apart from inhibiting mitosis, a process heavily dependent on cytoskeletal changes, colchicine also inhibits neutrophil motility and activity, leading to an anti-inflammatory effect. Colchicine also inhibits urate crystal deposition, which is enhanced by a low pH in the tissues, probably by inhibiting oxidation of glucose and subsequent lactic acid production in leukocytes. The inhibition of uric acid crystals is a vital aspect on the mechanism of gout treatment.
