CIPRO HC vs TRIMPEX 200
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.
Trimethoprim inhibits bacterial dihydrofolate reductase, blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA synthesis.
Instill 3 drops into the affected ear(s) twice daily (morning and evening) for 7 days.
200 mg orally once daily, or 100 mg orally twice daily.

Ciprofloxacin: 4-6 hours (prolonged to 6-9 hours in elderly or renal impairment). Hydrocortisone: 1-2 hours.
Terminal elimination half-life is 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in renal impairment (CrCl <30 mL/min), requiring dose adjustment.
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.
Renal excretion of unchanged drug accounts for approximately 60-80% of elimination, with an additional 10-20% as hepatic metabolites excreted in bile and feces.
