ENSTILAR vs FLUOCINOLONE ACETONIDE
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.
Fluocinolone acetonide is a potent corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress inflammatory cytokines (e.g., IL-1, IL-2, TNF-α). It also causes vasoconstriction and decreases cellular migration and immune response.
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.
Topical: Apply thin film to affected area 2-4 times daily. Otic: 0.01% solution, 5 drops into ear canal twice daily. Intralesional: 3.3 mg/mL, 0.5-1 mL per injection every 1-2 weeks.

Clinical Note
moderateFluocinolone acetonide + Levofloxacin
"The risk or severity of adverse effects can be increased when Fluocinolone acetonide is combined with Levofloxacin."
Clinical Note
moderateCalcipotriol: terminal half-life ~12 hours. Betamethasone dipropionate: terminal half-life ~16-22 hours. Clinically, this supports once-daily application.
Terminal elimination half-life is approximately 1.3-1.5 hours following topical application; after systemic absorption (oral or injection), half-life is 1.5-2.0 hours, necessitating multiple daily dosing for sustained effect.
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.
Primarily hepatic metabolism with renal excretion of metabolites (approximately 80% renal, 20% biliary/fecal). Less than 1% excreted unchanged in urine.
