title: Single daily dosing of aminoglycosides.
abstract: To evaluate the rationale behind dosing aminoglycosides as a single daily dose versus traditional dosing approaches, we conducted a MEDLINE search to identify all pertinent articles, and also reviewed the references of all articles. Single daily dosing of aminoglycosides is not a new concept, having been examined since 1974. The advantages of this regimen include optimum concentration-dependent bactericidal activity, longer dosing intervals due to the postantibiotic effect (PAE), and prevention of bacterial adaptive resistance. Because of longer dosing intervals, toxicity may also be delayed or reduced. Costs may be reduced due to decreased monitoring and administration. Clinically, the regimen has been implemented in various patient populations with reported success. Questions remain, however, about optimum dose, peak and trough serum concentrations, and dose adjustment in patients with renal impairment or neutropenia. More clinical experience with this method in large numbers of patients has to be published. Pharmacists can be instrumental in monitoring patients receiving once-daily therapy and by educating health care professionals as to the rationale behind the therapy.
