COR-OTICIN vs VERDESO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
Clobetasol propionate is a highly potent corticosteroid that binds to glucocorticoid receptors, inducing the synthesis of lipocortins which inhibit phospholipase A2, thereby reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
1-2 drops in each affected ear twice daily for 7 days.
Topical: apply a thin layer of VERDESO (clobetasol propionate) foam, 0.05%, to affected areas twice daily (morning and night) for up to 2 weeks; maximum weekly dose should not exceed 50 g.

Terminal half-life 4-6 hours; prolonged in renal impairment (up to 12-15 hours)
Terminal elimination half-life is approximately 100 hours (range 70-140 hours), supporting once-weekly topical application.
Renal (60-80% unchanged), fecal/biliary (5-10%)
Primarily biliary/fecal excretion (approximately 90%) as unchanged drug and metabolites; renal excretion accounts for <10%.
