OTOBIOTIC vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Otobiotic is a fixed-dose combination of ciprofloxacin (a fluoroquinolone antibiotic) and fluocinolone acetonide (a corticosteroid). Ciprofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, leading to bacterial DNA replication inhibition and cell death. Fluocinolone acetonide suppresses inflammation by binding to glucocorticoid receptors, modulating gene expression, and reducing inflammatory mediators.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
Adults and children: 3-4 drops into the affected ear twice daily for 7 days. Shake well before use.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

Terminal elimination half-life: 2-3 hours in patients with normal renal function; prolonged to 24-48 hours in anuria.
Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Renal elimination of unchanged drug: 60-80%; biliary/fecal elimination: 10-20%; the remainder undergoes hepatic metabolism.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
