It is one of the most frequently prescribed aminoglycosides due to its spectrum of activity, low cost, and availability. Gentamicin is effective against both gram-positive and gram-negative organisms but is particularly useful for the treatment of severe gram-negative infections including those caused by Pseudomonas aeruginosa. There is the added benefit of synergy when gentamicin is co-administered with other antibacterials such as beta-lactams. This synergistic activity is not only important for the treatment of complex infections, but can also contribute to dose optimization and reduced adverse effects.  Although gentamicin is well-established and may be used in a variety of clinical applications, it is also associated with severe adverse effects including nephrotoxicity and ototoxicity which may limit its use."}]
