Penetration of imidazole 2-hydroxybenzoate (ITF 182) into experimentally inflamed pleural and knee joint exudates.
The penetration of the two components of imidazole 2-hydroxybenzoate (ITF 182), imidazole and salicylate, into inflamed sites induced by intrapleural injection of carrageenin in the rat and by a urate-cotton pellet implantation in the knee joint of the rabbit is studied. The results obtained show that the two components of the salt penetrate rapidly the inflamed sites and display different kinetic profiles: imidazole diffuses throughout inflamed and non-inflamed fluids without any specific localization, salicylate shows preferential localization in inflamed fluids and remains longer than imidazole.
