Linezolid is a synthetic antibacterial agent belonging to the oxazolidinones class, which has clinical utility in the treatment of infections caused by aerobic gram-positive bacteria. Linezolid inhibits bacterial protein synthesis through a mechanism of action different from that of other antibacterial agents.

Description

Linezolid is a synthetic antibacterial agent belonging to the oxazolidinones class, which has clinical utility in the treatment of infections caused by aerobic gram-positive bacteria. Linezolid inhibits bacterial protein synthesis through a mechanism of action different from that of other antibacterial agents; therefore, cross-resistance between Linezolid and other classes of antibiotics is unlikely. Linezolid binds to a site on the bacterial 23S ribosomal RNA of the 50S subunit and prevents the formation of a functional 70S initiation complex, which is an essential component of the bacterial translation process.

Warning & Precautions

    The safety and efficacy of Linezolid formulation given for longer than 28 days have not been evaluated in controlled clinical trials. Thrombocytopenia has been reported in patients receiving Linezolid. Platelet counts should be monitored in patients who are at an increased risk of bleeding and have pre-existing thrombocytopenia.

    Common side effects include diarrhea, vomiting, headache, nausea, anemia, eosinophilia, and taste disturbances.

Drug interaction

    Monoamine oxidase inhibitors, adrenergic and serotonergic agents have the potentiality for interaction with Linezolid.

Use in special groups
