DERMOTIC vs ELDECORT
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.
Corticosteroid binding to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of cytokine production.
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.
Initial: 5-60 mg orally once daily, adjusted based on response; typical maintenance: 5-15 mg orally once daily.

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.
Terminal elimination half-life is 3.5 ± 1.2 hours in adults with normal renal function; prolonged to 6–8 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal excretion of unchanged drug (approximately 70-80%) with the remainder metabolized and excreted via biliary/fecal routes (20-30%).
Renal excretion of unchanged drug accounts for approximately 60% of the dose; fecal elimination contributes about 30% due to biliary secretion; the remaining 10% is metabolized.
