is a toxic natural product and secondary metabolite, originally extracted from plants of the genus
, also known as "Meadow saffron"). It was used originally to treat rheumatic complaints, especially gout.
Recently (July 30, 2009 ), US FDA has approved Colcrys(TM) (
colchicine, USP) for the
prophylaxis (prevention) of gout flares. Colcrys was first approved by the FDA on for the treatment of acute gout flares when taken at the first sign of a flare. Colcrys is also indicated for the treatment of Familial Mediterranean Fever (FMF) in adults and children 4 years of age or older. Colcrys is available via prescription at pharmacies nationwide.
As per the claim by the company (URL Pharma, Inc.) , two randomized clinical trials assessed the efficacy of colchicine 0.6 mg twice a day for the prophylaxis of gout flares in patients initiating treatment with uric-acid lowering therapy. In both trials, treatment with colchicine decreased the frequency of gout flares. Colchicine has been shown to be well-tolerated when paired with uric acid-lowering agents such as allopurinol. The dosing of Colcrys for gout flare prophylaxis is one tablet (0.6 mg) once or twice a day. The maximum daily dose for prophylaxis is two tablets (1.2 mg).
Uric acid-lowering agents are highly effective and well-established in chronic gout management, but the initiation of this therapy may sometimes trigger a gout flare, where as Colchicine has been proven to be effective in preventing flares when given in conjunction with uric acid-lowering therapy, except for the mild diarrhea. Hope patients suffering from gout will breathe a sigh of relief..
