Abstract
This article reviews the clinical pharmacokinetics, clinical toxicity and cost-effectiveness analysis of aminoglycosides and of dosing services for aminoglycosides. The reader is referred elsewhere for a review of the pharmacology, antimicrobial spectrum of activity and clinical use of these drugs. A critique of the more commonly used methods of aminoglycoside dosage determinations is included, based on the inter-individual variation in aminoglycoside disposition parameters. The advantages and disadvantages of arbitrary, predictive, and pharmacokinetic methods of dosing determination are summarized. Justification for the routine determination of serum aminoglycoside concentrations is reviewed. We review the lack of standardization of definitions for aminoglycoside-associated nephrotoxicity in published studies, and studies which illustrate these differences are highlighted. Evidence for the association between serum aminoglycoside concentrations and nephrotoxicity is examined. Ototoxicity is similarly reviewed. The concept of cost-effectiveness analysis is examined extensively in this review. We discuss the literature concerning the cost benefit analysis of drug dosing services.
