[Aminoglycosides].

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 b-lactam antibiotics in severe infections caused by Gram-negative bacilli.
