CYCLACILLIN vs NEO-RX
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.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis in susceptible bacteria.
250-500 mg orally every 6 hours.
100 mg intravenously every 12 hours.

0.5–1 hour in adults with normal renal function; prolonged to 10–15 hours in anuria.
Terminal elimination half-life is 2.5-3 hours in adults with normal renal function; increased to up to 10-15 hours in severe renal impairment (CrCl <30 mL/min). Clinically, this supports 8-hourly dosing intervals in normal renal function, with extended intervals in renal impairment.
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
moderatePrimarily renal (90%) as unchanged drug via glomerular filtration and tubular secretion; negligible biliary/fecal elimination (<5%).
Renal excretion accounts for 90-100% of elimination, primarily as the parent drug via glomerular filtration and tubular secretion. Urinary excretion: 90-100% unchanged. Fecal/biliary: negligible (<2%).
