Información del artículo
Los aminoglucósidos permanecen como una clase de antimicrobianos de uso habitual y eficaz en la práctica clínica. A pesar de que existen diversos mecanismos de resistencia continúan siendo activos frente a gran parte de los bacilos gramnegativos aerobios. En la actualidad, aunque pueden utilizarse en monoterapia en las infecciones urinarias, se utilizan fundamentalmente en combinación con betalactámicos en infecciones graves por bacilos gramnegativos. Los conocimientos sobre los parámetros farmacocinéticos y farmacodinámicos han sugerido su uso en monodosis, cuya eficacia ha sido similar a la administración en multidosis en diversos estudios, los cuales también han demostrado una tendencia a menor toxicidad. Entre los efectos adversos, la nefrotoxicidad y la ototoxicidad requieren una vigilancia cuidadosa durante su administración.

Aminoglycosides remain as a efficacious class of antimicrobials, commonly used in the clinical practice. In spite of the existence of several mechanisms of resistance, they continue being active against most of the aerobic Gram-negative bacilli. Currently, although aminoglycosides may be used as monotherapy in the urinary tract infections, they are mainly used in combination with β-lactam antibiotics in severe infections caused by Gram-negative bacilli. The knowledge about the pharmacokinetic and pharmacodynamic parameters of aminoglycosides has suggested their use in an once-daily dosing regimen. This dosing has shown as efficacious as multiple-daily dosing regimen in several studies, which also have shown a trend toward a lower toxicity. Among the adverse events, nephrotoxicity and ototoxicity require a careful evaluation during its administration.
