DECADERM vs TOPICORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone acts as a glucocorticoid receptor agonist, binding to the cytoplasmic glucocorticoid receptor, leading to modulation of gene transcription, suppression of pro-inflammatory cytokines, and induction of anti-inflammatory proteins, thereby reducing inflammation and immune responses.
Topical corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing production of prostaglandins and leukotrienes, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
DECADERM (dexamethasone) is typically administered as 0.75-9 mg/day orally in divided doses every 6-12 hours, depending on the condition. For acute indications, higher doses (up to 40 mg/day) may be given intravenously or intramuscularly.
Apply a thin film to the affected skin areas twice daily. Maximum adult dose: 50 g/week. Not for use on the face, axillae, or groin. Do not use under occlusive dressings.

Terminal elimination half-life approximately 36–54 hours (mean 44 h); prolonged in hepatic impairment.
Terminal elimination half-life: 2-4 hours for parent drug; clinical effect lasts longer due to receptor binding
