ENSTILAR vs PARICALCITOL
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.
Paricalcitol is a synthetic vitamin D analog that binds to the vitamin D receptor (VDR) in target tissues, including the parathyroid glands, kidneys, and intestines. It selectively activates VDR to suppress parathyroid hormone (PTH) secretion, reduce parathyroid cell proliferation, and modulate calcium and phosphate homeostasis with lower calcemic and phosphatemic effects compared to calcitriol.
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.
0.04 to 0.1 mcg/kg intravenously bolus no more frequently than every other day during dialysis, or 1 to 4 mcg orally once daily.

Clinical Note
moderateParicalcitol + Methyclothiazide
Calcipotriol: 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 5-7 hours in healthy subjects, but may be prolonged to 14-20 hours in patients with 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.
Primarily fecal (74%) via hepatobiliary excretion; renal elimination accounts for approximately 16% as unchanged drug.
