        It is a kind of anti-gout drug. The product is organic acid, strongly fat-soluble, self-discharge from tubular secretion, very easily to be absorbed back. Therefore, in the presence of probenecid, the transfer of some organic acids in the tubular body will be inhibited, reducing the excretion of other organic acids. Thereby, it is used to treat chronic gout with being safe and effective. It has no effects on acute gout pain and inflammation and can’t be applied to acute gout.
