ENSTILAR vs FLEXICORT
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.
FLEXICORT contains the active ingredient prednisolone, a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression, inhibition of phospholipase A2, and suppression of inflammatory mediators such as prostaglandins and leukotrienes.
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.
Flexicort is not a recognized drug name in authoritative pharmacological databases. Please verify the correct generic name. Assuming hydrocortisone: Typical adult dose is 10-40 mg orally daily in divided doses or as a single morning dose. Route: oral. Frequency: once or twice daily.

Calcipotriol: terminal half-life ~12 hours. Betamethasone dipropionate: terminal half-life ~16-22 hours. Clinically, this supports once-daily application.
8–12 hours; clinical context: once-daily dosing maintains therapeutic levels, with steady-state achieved within 2–3 days.
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 excretion of inactive metabolites accounts for 95% of elimination; biliary/fecal excretion is minimal at 5%.
