A patient with methicillin-resistant Staphylococcus aureus (MRSA) is no longer responding to the medication vancomycin (Vancocin). What medication might be indicated for this patient?
1. penicillin
2. gentamycin
3. tetracycline
4. linezolid
Correct Answer: 4
Linezolid (Zyvox) is the first antibiotic in a class of antibiotics called oxazolidinones. This antibiotic inhibits protein synthesis and is effective against organisms that are resistant to both vancomycin and methicillin. Because of its usefulness against those organisms, its use should be reserved for infections caused by vancomycin-resistant enterococci (VRE) and MRSA. Penicillin, gentamycin, and tetracycline are not identified as medications to treat vancomycin-resistant Staphylococcus aureus.
