RESUMO

Nine mongrel dogs were studied to evaluate the excretion of cefamandole (five dogs) and cephalothin (four dogs) in the pancreatic fluid. Each dog was studied before and after the induction of pancreatitis, with 2 weeks between studies. After intravenous administration of a 25-mg/kg dose of either cephalosporin, serum and pancreatic fluid concentrations were monitored for 6 h. Both cephalothin and cefamandole were excreted in bactericidal concentrations in the normal pancreas and in acute pancreatitis. Clearance of cefamandole (290 ml/min) and cephalothin (348 ml/min) were similar pre- and postinduction of pancreatitis. Serum albumin concentration was less during the post-pancreatitis phase compared with the prepancreatitis phase. Penetration of cephalothin was reduced in pancreatitis, whereas cefamandole penetration increased in pancreatitis.
