DERMOTIC vs SERNIVO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dermotic (fluocinolone acetonide) is a corticosteroid that acts by inducing phospholipase A2 inhibitory proteins, collectively called lipocortins. These proteins inhibit the release of arachidonic acid, thereby suppressing the synthesis of prostaglandins and leukotrienes, leading to anti-inflammatory and immunosuppressive effects.
SERNIVO (clobetasol propionate) is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects through induction of phospholipase A2 inhibitory proteins, collectively called lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.
Each 1 mL contains 1 mg betamethasone valerate, 10 mg neomycin sulfate, 10,000 units polymyxin B sulfate. Apply 3-4 drops into affected ear(s) 2-3 times daily for 7-10 days.
Apply a thin layer to affected area twice daily for up to 2 weeks.

Terminal elimination half-life is 12-18 hours. In patients with renal impairment, half-life may be prolonged; dose adjustment recommended for CrCl <30 mL/min.
Approximately 3 hours (parent drug); clinical duration extended via formulation.
Primarily renal excretion of unchanged drug (approximately 70-80%) with the remainder metabolized and excreted via biliary/fecal routes (20-30%).
Primarily renal excretion of inactive metabolites; <5% unchanged. Minor biliary/fecal elimination.
