CYCLACILLIN vs XERAVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cyclacillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
250-500 mg orally every 6 hours.
200 mg intravenously over 60 minutes every 12 hours

Clinical Note
moderateCyclacillin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cyclacillin."
Clinical Note
moderateCyclacillin + Mycophenolic acid
"The serum concentration of the active metabolites of Mycophenolic acid can be reduced when Mycophenolic acid is used in combination with Cyclacillin resulting in a loss in efficacy."
Clinical Note
moderateCyclacillin + Plicamycin
"The serum concentration of Plicamycin can be decreased when it is combined with Cyclacillin."
Clinical Note
moderate0.5–1 hour in adults with normal renal function; prolonged to 10–15 hours in anuria.
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 (90%) as unchanged drug via glomerular filtration and tubular secretion; negligible biliary/fecal elimination (<5%).
Fecal (approximately 80-90% as unchanged drug); renal (less than 1% as unchanged drug).
