Eravacycline, known as Xerava by Tetraphase Pharmaceuticals, is a fully synthetic fluorocycline antibiotic of the tetracycline class with activity against clinically significant gram-negative, gram-positive aerobic, and facultative bacteria. This includes most of those bacteria resistant to cephalosporins, fluoroquinolones, -lactam/-lactamase inhibitors, multidrug-resistant strains, and carbapenem-resistant Enterobacteriaceae, and the majority of anaerobic pathogens. It was first approved by the FDA on August 27, 2018. Eravacycline has demonstrated superior potency to that of antibiotics that are currently being marketed for intraabdominal infections.

Eravacycline is a Tetracycline-class Antibacterial.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

5 Pharmacology and Biochemistry

5.4 Absorption, Distribution and Excretion

Absorption

Following single-dose intravenous administration, eravacycline AUC (area under the curve) and Cmax (maximum concentration) increase dose-proportionally for doses from 1 mg/kg - 3 mg/kg (3 times the approved dose). There is approximately 45% accumulation following intravenous dosing of 1 mg/kg every 12 hours.

Route of Elimination

Following a single intravenous dose of radiolabeled eravacycline 60 mg, approximately 34% of the dose is excreted in urine and 47% in feces as unchanged eravacycline (20% in urine and 17% in feces) and metabolites.

Volume of Distribution

The volume of distribution at steady-state is approximately 321 L.

Clearance

17.82 L/min (standard deviation of 3.4).

5.5 Metabolism/Metabolites

Eravacycline is metabolized primarily by CYP3A4- and FMO-mediated oxidation.

5.6 Biological Half-Life

The mean elimination half-life is 20 hours.

5.7 Mechanism of Action

Eravacycline is a fluorocycline antibacterial of the tetracycline class of antibacterial drugs. Eravacycline disrupts bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the incorporation of amino acid residues into elongating peptide chains. In general, eravacycline is bacteriostatic against gram-positive bacteria (e.g., Staphylococcus aureus and Enterococcus faecalis); however, in vitro bactericidal activity has been shown against certain strains of Escherichia coli and Klebsiella pneumoniae.
