Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Reversibly binds to the 50S ribosomal subunit, inhibiting peptidyl transferase activity and blocking protein synthesis in bacteria.
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.
Intravenous, 50 mg/kg/day divided every 6 hours; maximum 4 g/day.
250-500 mg orally every 6 hours.

Terminal elimination half-life is approximately 1.5-3.5 hours in adults with normal renal and hepatic function. In neonates (first 2 weeks of life), half-life is prolonged to 10-24 hours due to immature hepatic conjugation. In patients with severe hepatic impairment, half-life may exceed 12 hours, necessitating dose adjustment.
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.
Approximately 80-90% of the dose is excreted renally as unchanged drug and as the inactive chloramphenicol base (formed by hydrolysis in the liver and kidneys). Biliary excretion accounts for about 5-10%, with some enterohepatic circulation. Fecal excretion is negligible (<2%).
Primarily renal (90%) as unchanged drug via glomerular filtration and tubular secretion; negligible biliary/fecal elimination (<5%).
