Abstract: Linezolid is a novel oxazolidinone antibiotics and a key drug for treatment of drug-resistant tuberculosis. With narrow therapeutic window, linezolid is characterized with great efficacy, and high incidence of adverse reaction. How to tailor optimal dosage for every patient to balance efficacy and safety is still a problem for clinician. Therapeutic drug monitoring (TDM) remains a standard clinical technique for using plasma drug concentrations to make informed dosing decisions. Many studies worldwide have demonstrated the possible optimal dosage of linezolid in drug-resistant TB patients, explored the relationship between the trough concentration, peak concentration and the incidence of adverse reactions of linezolid by TDM, particularly for fragile patients, like the aged, children and patients with injured liver and kidney function. We hereby review the mechanism of linezolid, the relationship between dosage and safety of linezolid, risk factors affecting the concentration of linezolid, evidence and available methods of TDM of linezolid, so as to provide a reference for clinician to do TDM of linezolid during the treatment of drug-resistant tuberculosis.
