DERMOTIC vs VANOS
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.
VANOS (fluocinonide 0.1% cream) is a corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2 and reduction of prostaglandin and leukotriene synthesis, resulting in anti-inflammatory, antipruritic, and vasoconstrictive effects.
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 areas once or twice daily. Not for use longer than 2 weeks; maximum 15 g per day.

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.
The terminal elimination half-life is approximately 7.5 hours (range 5-12 hours). This supports twice-daily or once-daily dosing for sustained local effect.
Primarily renal excretion of unchanged drug (approximately 70-80%) with the remainder metabolized and excreted via biliary/fecal routes (20-30%).
Primarily renal excretion (glucuronidation and sulfation); minimal biliary elimination (<5%). Approximately 60-70% of the dose is excreted in urine as metabolites, with <1% unchanged.
