CALCIPOTRIENE vs ENSTILAR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcipotriene is a synthetic vitamin D3 analogue that binds to vitamin D receptors (VDR) in keratinocytes, inhibiting cell proliferation and promoting differentiation. It also modulates immune responses by reducing cytokine production.
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 a thin layer of 0.005% ointment, cream, or solution to affected areas once or twice daily. Maximum 100 g per week.
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.

The terminal elimination half-life of calcipotriene is approximately 5–6 hours following topical application. Systemic clearance is rapid due to extensive hepatic metabolism, leading to minimal accumulation.
Calcipotriol: terminal half-life ~12 hours. Betamethasone dipropionate: terminal half-life ~16-22 hours. Clinically, this supports once-daily application.
Calcipotriene is rapidly metabolized in the liver to inactive metabolites; less than 1% of the dose is excreted unchanged in urine. Fecal excretion accounts for approximately 70% of the administered dose, primarily as metabolites, with about 16% excreted in urine.
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.
