Is minocycline a solution for multidrugresistant Acinetobacter baumannii?

Minocycline is an old, safe, second-line antimicrobial agent that has drawn attention over the last fewyears as a possible therapeutic option against multidrug-resistant Acinetobacter baumannii (MDRAB) clinical isolates. Recent in vitro and in vivo results indicate that minocycline is a valid, alternative treatment option for minocycline-susceptible MDRAB. Although effective alone, its administration as monotherapy should be avoided. Combinations with other antimicrobials can reduce the MIC of each component, present synergism and minimize the risk for drug resistance. Owing to its limited solubility in urine, it should be avoided for urinary pathogens. The present article reports all available information regarding its use as a therapeutic option against MDRAB
