Description
Mechanism of Action
Colchicine, a phenanthrene derivative, exerts its effect by reducing the inflammatory response to the deposited urate crystals and also by diminishing phagocytosis in joints. It inhibits lactic acid production by leucocytes, thereby interrupting urate deposition and inflammatory response that sustains the acute gout attack.
