CYCLACILLIN vs MYCIFRADIN
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, inhibiting bacterial protein synthesis by causing misreading of mRNA and incorporation of incorrect amino acids into the growing peptide chain.
250-500 mg orally every 6 hours.
1-2 g orally every 6 hours for 7-14 days. Or 500 mg intramuscularly every 12 hours.

0.5–1 hour in adults with normal renal function; prolonged to 10–15 hours in anuria.
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
moderateTerminal elimination half-life is 9–12 hours in patients with normal renal function; may extend to >20 hours in impaired renal function, necessitating dose adjustment.
Primarily renal (90%) as unchanged drug via glomerular filtration and tubular secretion; negligible biliary/fecal elimination (<5%).
Primarily renal excretion of unchanged drug via glomerular filtration; >90% of absorbed dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<1%) with fecal elimination accounting for <1%.
