Several studies have suggested the risk of thrombocytopenia with tedizolid, a second-in-class oxazolidinone antibiotic (approved June 2014), is less than that observed with linezolid (first-in-class oxazolidinone). Using data from the Food and Drug Administration adverse event reporting system (July 2014 through December 2016), we observed significantly increased risks of thrombocytopenia of si...

We report a unique case of an adverse interaction between the oxazolidinone antibiotic linezolid, the tricyclic antidepressant amitriptyline and the opioid analgesic fentanyl in a 68-year-old woman with advanced ischemic peripheral arterial disease and sepsis, under empirical antibiotic treatment. We also summarize the current relevant literature as identified via PubMed, EMBASE, and PsycINFO a...

Pseudomonas aeruginosa is a Gram-negative pathogenic bacterium responsible for severe infections in which resistance to most of the approved families of antibiotics is increasing. Oxazolidinone antibiotics are active against many Gram-positive bacteria, but are only weakly active against Gram-negative pathogens. We describe the synthesis of conjugates between a catechol moiety and oxazolidinone...

linezolid (lzd), severed as the first oxazolidinone antibiotic, was active against multidrug-resistant gram-positive strains. lzd can induce thrombocytopenia, anemia and leukocytopenia. currently, reports on pure red cell aplasia (prca) cases induced by lzd are relatively rare [4-7]. in this paper, we reported a patient with prca twice induced by lzd. a 37-year-old man was diagnosed with myelody...

Linezolid, an oxazolidinone antibiotic, inhibits bacterial protein synthesis by binding to 23S ribosomal RNA (rRNA). We studied 3 patients who experienced lactic acidosis while receiving linezolid therapy. The toxicity may have been caused by linezolid binding to mitochondrial 16S rRNA. Genetic polymorphisms may have contributed to the toxicity in 2 patients.

The activity of a new oxazolidinone antimicrobial, AZD2563, was assessed against >500 clinical isolates of enterococci representing six species. All isolates, including those resistant to other antibiotic classes, were inhibited by AZD2563 at concentrations </=2 micro g/ml, except for four strains resistant to linezolid. In most cases, AZD2563 was twofold more active than linezolid against ente...

A bioluminescent clinical isolate of Streptococcus pneumoniae was used to test the real-time effects of the oxazolidinone antibiotic, linezolid, on metabolism compared with effects on cell replication. Viable counts and bioluminescence measurements showed that linezolid has little bactericidal effect, which was similar at minimum (6 mg/L), intermediate (13 mg/L) and maximum (20 mg/L) serum conc...

Linezolid is an oxazolidinone antibiotic with weak monoamine oxidase (MAO) type A and MAO type B inhibitory effects. Linezolid has been associated with serotonin toxicity when used concomitantly with multiple medications that are known to increase serotonin concentrations. We report the case of a 65-year-old woman with signs and symptoms of serotonin toxicity following administration of linezol...
