CIPRODEX vs KETEK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciprofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, blocking bacterial DNA replication; dexamethasone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
Ciprofloxacin 0.3% and dexamethasone 0.1% otic suspension: 4 drops into affected ear(s) twice daily for 7 days.
Telithromycin 800 mg orally once daily for 7-10 days.

Ciprofloxacin: terminal elimination half-life 3-5 hours (prolonged to 5-10 hours in renal impairment). Dexamethasone: biological half-life 36-54 hours.
Terminal half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Ciprofloxacin: 50-70% renal (glomerular filtration and tubular secretion), 20-35% biliary/fecal. Dexamethasone: renal elimination of metabolites, <5% unchanged.
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
