PYOCIDIN vs XERAVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pyocidin is a bactericidal antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Eravacycline is a tetracycline-class antibacterial that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from attaching to the A-site. It exhibits activity against a broad range of Gram-positive, Gram-negative, and anaerobic bacteria, including many tetracycline-resistant strains due to modifications circumventing common resistance mechanisms.
5 mg/kg intramuscular or subcutaneous every 24 hours. Max dose 300 mg per injection.

Terminal elimination half-life is 2-3 hours in patients with normal renal function; extends to 12-18 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 42 hours (range 30-60 hours) in healthy subjects; prolonged in elderly patients and those with severe hepatic impairment.
Primarily renal excretion of unchanged drug (60-70%), with 20-30% biliary excretion and minor fecal elimination (<10%).
Fecal (approximately 80-90% as unchanged drug); renal (less than 1% as unchanged drug).
