Linezolid possesses nonspecific monoamine oxidase inhibition. Early recognition and withdrawal of the offending agents is essential. Tahir N. Cases of serotonin syndrome, which is characterized by mental changes, sweating or shivering, muscle twitching, and coordination problems, have been reported as an adverse interaction with linezolid for drugs of the selective serotonin reuptake inhibitor SSRI class as well as for serotonin-norepinephrine reuptake inhibitors SNRI. US Pharm. Linezolid also interacts with certain foods, such as those containing tyramine e. Linezolid is metabolized by oxidation and is not a substrate of the cytochrome P system.

    Not all serotonergic psychiatric drugs have an equal capacity to cause serotonin syndrome with linezolid. Most cases from the FDA's Adverse.

The antibacterial agent linezolid is a nonselective inhibitor of A recent case of serotonin syndrome was reported with concur- rent use of.
    Although toxicity from coadministration of linezolid and serotonergic agents is not reported in phase I, II, or III trials, 2 multiple case reports describe temporally related linezolid administration and serotonin toxicity manifesting as serotonin syndrome.

    Serotonergic agents promote synaptic release of serotonin or inhibit the metabolism or reuptake of serotonin, leading to increased levels in the central nervous system and periphery. Monitoring may include complete blood counts, a chemistry panel especially serum bicarbonaterenal and hepatic function, mental status, and vital signs.

    Ultimately, the recommendation to delay start of linezolid for two weeks is not clinically realistic. Linezolid also interacts with certain foods, such as those containing tyramine e. Serotonergic agents promote synaptic release of serotonin or inhibit the metabolism or reuptake of serotonin, leading to increased levels in the central nervous system and periphery.

    For example, fluoxetine has an elimination half-life ranging from one to six days, and an active metabolite, norfluoxetine, may have a half-life as long as 16 days. Linezolid inhibits protein synthesis of susceptible bacteria by binding to 23S on the 50S subunit of bacterial ribosomal RNA to prevent the formation of the 70S-initiation complex necessary for translation.

    While the precise mechanism by which linezolid interacts with these drugs has not been determined, it may result from inhibition of monoamine oxidase A.

    Since linezolid was approved by the FDA for use, there have been 17 published case reports documenting the occurrence of symptoms of serotonin toxicity in. The FDA has issued an updated statement on the potential for serious central nervous system toxicity when patients taking serotonergic.

    A case of serotonin toxicity was defined as having the following: (1) linezolid as Linezolid was approved by the FDA for oral and intravenous use in [1].
    Cases of serotonin syndrome, which is characterized by mental changes, sweating or shivering, muscle twitching, and coordination problems, have been reported as an adverse interaction with linezolid for drugs of the selective serotonin reuptake inhibitor SSRI class as well as for serotonin-norepinephrine reuptake inhibitors SNRI.

    This enzyme is needed for the metabolism of serotonin in the brain, and its inhibition can lead to toxic buildup of this neurotransmitter.

    Linezolid is metabolized by oxidation and is not a substrate of the cytochrome P system.

    It is recommended in the literature to allow two weeks between discontinuation of a serotonergic agent and initiation of linezolid. Linezolid also interacts with certain foods, such as those containing tyramine e.

    Linezolid is metabolized by oxidation and is not a substrate of the cytochrome P system. These classes of drugs include paroxetine Paxilfluvoxamine Luvoxfluoxetine Prozac, Symbyax sertraline Zoloftcitalopram Celexaescitalopram Lexaprovilazodone Viibrydvenlafaxine Effexordesvenlafaxine Pristiqand duloxetine Cymbalta.

    If linezolid must be used, the serotonergic drug must be stopped immediately, and the patient must be carefully monitored for two weeks for signs of serotonin syndrome -- except if the drug is fluoxetine, which has a long half-life, necessitating five weeks of monitoring.

      Serotonin syndrome occurs when there is excess central nervous system or peripheral serotonergic activity and is characterized by altered mental status, autonomic dysfunction, and neuromuscular abnormalities. Tahir N.

      These select patients should be educated on the symptoms of serotonin syndrome and should be closely monitored by their primary caregivers. While the precise mechanism by which linezolid interacts with these drugs has not been determined, it may result from inhibition of monoamine oxidase A.
