Effect of creatinine on various experimentally induced inflammatory models.

Creatinine, an aminoacid, has been studied for its anti-inflammatory activity. It is orally effective in suppressing the inflammatory responses produced by carrageenan, 5-hydroxytryptamine, nystatin and formaldehyde. It is observed that the antiinflammatory effect of creatinine is not owing to counter irritant action. It is suggested that it may partially be mediating its anti-inflammatory activity by interfering with the action or/and synthesis of prostaglandins. Like phenylbutazone it also possesses an analgesic action.
