Tedizolid: A New Oxazolidinone Antibiotic for Skin and Soft Tissue Infections.

Abstract

To review the chemistry, pharmacology, microbiology, pharmacodynamics, pharmacokinetics, clinical efficacy, tolerability, drug interactions, dosing, and administration of tedizolid phosphate (TDZ). A search of PubMed using the terms "tedizolid," "torezolid," "TR-701," "TR-700," "DA-7157," and "DA-7218" was performed. The manufacturer's Web site was also reviewed to further identify relevant information. All English-language articles from 2006 to November 2014 appearing in these searches were reviewed for relevance to this paper. In addition, their bibliographies were reviewed to identify any articles not uncovered in the searches. TDZ is the second oxazolidinone antibiotic with a spectrum of activity targeted against gram-positive organisms including methicillin-resistant Staphylococcus aureus . It is administered via intravenous infusion or orally without regard to food. The primary route of elimination is fecal excretion. Advanced age, hepatic dysfunction, or renal impairment does not alter its disposition. Phase III clinical trials have demonstrated that TDZ 200 mg daily for 6 days is noninferior to linezolid 600 mg twice daily for 10 days in the treatment of adults with skin and soft tissue infections caused or suspected to be caused by gram-positive organisms. TDZ has a side effect profile similar to that of linezolid and a lower potential for drug interactions. TDZ has been shown to be safe and effective for the treatment of adults with skin and soft tissue infections. Further research is needed to refine its role, particularly for the treatment of patients requiring a longer duration of therapy and in those receiving concomitant serotonergic agents.
