CLOCORTOLONE PIVALATE vs COR-OTICIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clocortolone pivalate is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions. It binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine release.
COR-OTICIN is a combination product containing hydrocortisone (a corticosteroid with anti-inflammatory and immunosuppressive properties) and neomycin (an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit) and polymyxin B (a polymyxin antibiotic that disrupts bacterial cell membrane permeability).
Topical: Apply a thin film to affected area once or twice daily. Not for ophthalmic use. Maximum duration of 2 weeks per course.
1-2 drops in each affected ear twice daily for 7 days.

Terminal elimination half-life is approximately 2.5 hours (range 1-4 hours), reflecting rapid clearance; clinical duration exceeds half-life due to tissue binding.
Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Primarily renal (approximately 80%) as glucuronide and sulfate conjugates; minor biliary/fecal excretion (20%).
Renal (60-80% unchanged), fecal/biliary (5-10%)
