DERMOTIC vs DIPROLENE AF
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.
Betamethasone dipropionate is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, thereby reducing the release of arachidonic acid and subsequent production of prostaglandins and leukotrienes. This results 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 film to affected skin areas twice daily. Maximum 45 g per week. Not to exceed 2 consecutive weeks of treatment.

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 2.5-3 hours (terminal half-life) for betamethasone dipropionate (active moiety); clinical effects persist beyond half-life due to receptor-mediated activity.
Primarily renal excretion of unchanged drug (approximately 70-80%) with the remainder metabolized and excreted via biliary/fecal routes (20-30%).
Primarily hepatic metabolism; inactive metabolites excreted renally (approximately 80-85% as metabolites in urine) and fecally (approximately 15-20%).
