Mechanism of Action for SIVEXTRO

SIVEXTRO provides coverage against key Gram-positive bacteria in Acute Bacterial Skin and Skin Structure Infections (ABSSSI)

SIVEXTRO provides coverage against:

  • Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible Staphylococcus aureus (MSSA) isolates
  • Streptococcus isolates
    • Streptococcus agalactiae
    • Streptococcus pyogenes
    • Streptococcus anginosus group (includes S. anginosus, S. intermedius, S. constellatus)
  • Enterococcus faecalis

Mechanism of Action for SIVEXTRO

  • Antibacterial activity mediated by binding to the 50S subunit of the bacterial ribosome, resulting in inhibition of protein synthesis
  • Tedizolid inhibits bacterial protein synthesis through a mechanism of action different from that of other nonoxazolidinone-class antibacterial drugs
  • In vitro studies showed tedizolid is bacteriostatic against key Gram-positive bacteria in ABSSSI, including MRSA and MSSA

Indication

SIVEXTRO is an oxazolidinone-class antibacterial indicated in adults and pediatric patients 12 years of age and older for the treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-resistant [MRSA] and methicillin-susceptible [MSSA] isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group (including Streptococcus anginosus, Streptococcus intermedius and Streptococcus constellatus), and Enterococcus faecalis.

 

Usage

To reduce the development of drug-resistant bacteria and maintain the effectiveness of SIVEXTRO and other antibacterial drugs, SIVEXTRO should be used only to treat ABSSSI that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Selected Safety Information

Patients with neutropenia: The safety and efficacy of SIVEXTRO in patients with neutropenia (neutrophil counts <1000 cells/mm³) have not been adequately evaluated. In an animal model of infection, the antibacterial activity of SIVEXTRO was reduced in the absence of granulocytes. Alternative therapies should be considered when treating patients with neutropenia.

 

Clostridioides difficile–associated diarrhea (CDAD), ranging from mild diarrhea to fatal colitis, has been reported with nearly all systemic antibacterial agents, including SIVEXTRO. Evaluate all patients who present with diarrhea following antibacterial drug use. Careful medical history is necessary because CDAD has been reported to occur more than two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, antibacterial use not directed against C. difficile should be discontinued, if possible.

 

Development of drug-resistant bacteria: Prescribing SIVEXTRO in the absence of a proven or strongly suspected bacterial infection or prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

 

Adverse reactions: The most common adverse reactions (≥2%) in adults for SIVEXTRO are nausea (7%), headache (5%), diarrhea (4%), vomiting (3%), and dizziness (2%).

 

In adult patients receiving SIVEXTRO intravenously, infusion- or injection-related adverse reactions including but not limited to: phlebitis, injection- or infusion-site pain or swelling, injection-site reaction, erythema, or induration, and infusion-related reaction occurred (4%).

 

The most common adverse reactions (>2%) in pediatric patients 12 years of age and older are phlebitis (3%) and increased hepatic transaminases (3%).

 

Drug interactions with BCRP substrates: SIVEXTRO (when administered orally) can increase the plasma concentrations of orally administered Breast Cancer Resistance Protein (BCRP) substrates and the potential for adverse reactions. Monitor for adverse reactions related to the concomitant BCRP substrates if coadministration cannot be avoided.
