Drug Action
Linezolid, an oxazolidinone antibacterial, is active against Gram-positive bacteria including meticillin- resistant Staphylococcus aureus (MRSA), and glycopeptide- resistant enterococci. Resistance to linezolid can develop with prolonged treatment or if the dose is less than that recommended. Linezolid is not active against common Gram-negative organisms; it must be given in combination with other antibacterials for mixed infections that also involve Gram-negative organisms.
