ENSTILAR vs HC #1
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ENSTILAR is a combination of calcipotriene (a vitamin D analog) and betamethasone dipropionate (a corticosteroid). Calcipotriene binds to vitamin D receptors, modulating cell proliferation and differentiation. Betamethasone suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.

Apply to affected area once daily for up to 4 weeks. Maximum 100 g/day or 30 g/week. Not for use on face, axillae, or groin.
Hydrocortisone: 100-200 mg IV as initial dose, then 50-100 mg IV every 6 hours, or 0.18 mg/kg/h IV continuous infusion.

Calcipotriol: terminal half-life ~12 hours. Betamethasone dipropionate: terminal half-life ~16-22 hours. Clinically, this supports once-daily application.
2–4 hours (terminal); prolonged in renal impairment.
Calcipotriol is primarily excreted via bile/feces (approximately 70% of absorbed dose). Betamethasone dipropionate is mainly excreted renally (60-70% as metabolites) and up to 20-30% via feces. For the combination, renal excretion of betamethasone metabolites predominates, with fecal excretion of calcipotriol.
Renal: 90% as unchanged drug; fecal: 10%.
