Summary
Aminoglycosides still represent a mainstay in the treatment of serious infections caused by Gram-negative bacilli in elderly patients. The aging process is accompanied by various physiological changes (e.g. alterations in body composition, impairments in certain organ functions), which may affect drug disposition and, subsequently, drug action. For aminoglycosides that are eliminated by the renal route, kidney function is the key parameter that should be taken into account when dosage regimens are calculated. Because there is a progressive decline in renal function with aging, the glomerular filtration rate should be estimated for each patient. Any change in creatinine clearance (CLCR) should result in a proportional correction of the dosage regimen. Such individualised dosage of aminoglycosides is particularly important because of their narrow therapeutic indices.
There are no conclusive data which indicate that age per se affects the elimination of aminoglycoside antibiotics. Overdosage may result from overestimation of renal function if crude serum creatinine (SCr) levels are used as a guide.
Nomograms for the relationship between SCr and CLCR have been developed. However, nomograms should be used with caution because substantial inter-individual variability in the plasma concentration-clearance relationship is still observed. Therefore, the choice of a maintenance dose based on an assessment of renal function, which may change rapidly, should always be considered as preliminary, and verification by serum concentration measurements is necessary.
As a result, the use of aminoglycoside serum concentration monitoring during therapy as the most important guide for dosage adjustment is particularly important in the elderly, and is indispensable in conjunction with frequent assessment of renal function. Although a matter of debate, the value of serum concentration monitoring has been demonstrated. With traditional multiple daily dosage, monitoring peak and trough concentrations has been recommended. For once daily dosage, however, no guidelines relating to therapeutic and/or toxic concentrations are available yet. In the meantime, we recommend monitoring at least trough concentrations.
Once daily administration of aminoglycosides has emerged as a new mode of treatment. Compared with multiple daily administration, once daily dosage may have a number of advantages, and many clinical trials comparing the efficacy or safety of both modes have shown either superiority or equivalence of the new mode in most indications. At present, however, no data from studies of once daily administration in young compared with elderly adults are available.
