ABSTRACT
The rat granuloma pouch model was used to study the penetration of imipenem into inflammatory exudate and its efficacy in an experimental local infection. Rats were given a single intravenous injection of drug via the tail vein at a dose of 40 mg/kg. The peak concentrations of imipenem, ceftizoxime, cefazolin, and cefsulodin in exudates ranged from 10.1 to 12.3 mg/l, except that ampicillin achieved only 5.4 mg/l. Imipenem rapidly reached peak concentration after injection, but the half life for elimination of imipenem from exudate was 77.7 min, which was shorter than that of other beta-lactam antibiotics. Imipenem exhibited more rapid reduction in bacterial growth than cefsulodin in an experimental local infection with Pseudomonas aeruginosa in the pouch model. The results suggested that imipenem was an effective agent in treating the local infection.
