CIPRO HC vs CYCLACILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, preventing DNA replication and transcription; hydrocortisone suppresses inflammation via glucocorticoid receptor activation.
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.
Instill 3 drops into the affected ear(s) twice daily (morning and evening) for 7 days.
250-500 mg orally every 6 hours.

Ciprofloxacin: 4-6 hours (prolonged to 6-9 hours in elderly or renal impairment). Hydrocortisone: 1-2 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.
Ciprofloxacin: ~50-70% excreted renally as unchanged drug, ~15% as metabolites; ~20-30% eliminated via biliary/fecal route. Hydrocortisone: metabolized hepatically, renal excretion of metabolites.
Primarily renal (90%) as unchanged drug via glomerular filtration and tubular secretion; negligible biliary/fecal elimination (<5%).
