FDA Approves New Antibiotics Xerava (Eravacycline)

The US Food and Drug Administration has given approval of Xerava (eravacycline) for treating complex intra-abdominal infections.

Eravacycline

Eravacycline (Xerava) is a synthetic halogenated tetracycline course antibiotic in evolution from Tetraphase Pharmaceuticals. It’s closely associated with tigecycline.

Xerava is approved for the treatment of complex intra-abdominal illnesses in patients age 18 years or older. To decrease the progression of drug-resistant bacteria and take care of the effectiveness of both Xerava and other antibacterial drugs, Xerava ought to be used only to treat or prevent infections that are proven or strongly suspected to be brought on by susceptible bacteria.

How it Work?

Eravacycline interrupts bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the incorporation of amino acid residues to elongating peptide chains. Generally, eravacycline is bacteriostatic against gram-positive germs (e.g., Staphylococcus aureus and Enterococcus faecalis); nonetheless, in vitro bactericidal activity has been shown against specific strains of Escherichia coli and Klebsiella pneumoniae.

Uses

Eravacycline is used in the following infections and medical conditions,
