DERMATOP vs DERMOTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednicarbate is a corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of arachidonic acid from membrane phospholipids.
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.
Apply a thin layer to affected skin areas twice daily (morning and evening) for up to 4 weeks. Do not use more than 50 g per week.
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.

Terminal elimination half-life: approximately 100 hours (range 68-120 hours) following topical administration; prolonged accumulation with chronic use due to high lipophilicity and slow release from skin depot.
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.
Primarily hepatic metabolism with inactive metabolites; <10% excreted renally as unchanged drug; minimal biliary/fecal elimination.
Primarily renal excretion of unchanged drug (approximately 70-80%) with the remainder metabolized and excreted via biliary/fecal routes (20-30%).
