title: Pharmacokinetics of antimicrobial drugs in cystic fibrosis. Aminoglycoside antibiotics.
abstract: Patients with cystic fibrosis (CF) show abnormal aminoglycoside pharmacokinetics. After a conventional dose, the serum concentrations in CF patients are lower than those in nonCF patients. The lower serum concentrations in CF might be explained by increased total body clearance and/or a larger volume of distribution. The therapeutic range of aminoglycosides is narrow due to oto- and nephrotoxicity. The changed pharmacokinetics and the narrow therapeutic range make it difficult to ensure that patients with CF are adequately and safely treated with aminoglycosides. The mode of administration of aminoglycosides influences the antibacterial effect of these agents on Pseudomonas aeruginosa and the development of possible side effects. The therapeutic implications of these facts are discussed.
