RESUMO
The pharmacokinetics of azlocillin were studied in 10 cystic fibrosis patients, ranging in age from 11 to 28 years. The patients received a 9- to 23-day course of 350 mg of azlocillin per kg in four or six divided daily doses in combination with am aminoglycoside. Blood and urine samples were collected at specified times after the last dose of the course of azlocillin therapy and then assayed for azlocillin content. Pharmacokinetic parameters were determined by noncompartmental analysis. Mean values for serum half-life (1.74 h), disposition constant (0.41 h-1), total body clearance (123 ml/kg per h), and renal clearance (58 ml/kg per h) were determined. All patients exhibited improvement with respect to clinical and laboratory parameters and displayed no adverse reactions. The pharmacokinetic analysis offers further evidence of the dose-dependent nature of azlocillin elimination, but elimination did not appear to be altered in cystic fibrosis patients.
