The dynamics of the acute inflammatory response was observed in the experiment modeling caragenin-induced rat paw inflammation. The changes in the volume of damaged limb (paw edema) and indices of free radical oxidation were registered. Acetylsalicylic acid in the dose of 100 mg/kg was shown to reduce the development of inflammation. Hypoxen and metaprot in the dose of 50 mg/kg have got low anti-inflammatory activity, but potentiated the effect of acetylsalicylic acid. Simultaneous enteral administration of hypoxen and metaprot with the acetylsalicylic acid during the treatment with caragenin the powerful anti-inflammatory effect was marked, it was presented with a significant decrease in the parameters of inflammation recorded and rapid recovery of the damaged limb. The combination of hypoxen with acetylsalicylic acid was the most effective one.
