CIPRO HC vs PYOCIDIN
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.
Pyocidin is a bactericidal antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Instill 3 drops into the affected ear(s) twice daily (morning and evening) for 7 days.
5 mg/kg intramuscular or subcutaneous every 24 hours. Max dose 300 mg per injection.

Ciprofloxacin: 4-6 hours (prolonged to 6-9 hours in elderly or renal impairment). Hydrocortisone: 1-2 hours.
Terminal elimination half-life is 2-3 hours in patients with normal renal function; extends to 12-18 hours in severe renal impairment (CrCl <30 mL/min).
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 excretion of unchanged drug (60-70%), with 20-30% biliary excretion and minor fecal elimination (<10%).
