CALCIPOTRIENE vs ZEMPLAR
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.
Vitamin D receptor agonist; binds to vitamin D receptors, regulating gene expression of calcium-binding proteins and cellular proliferation/differentiation.
Apply a thin layer of 0.005% ointment, cream, or solution to affected areas once or twice daily. Maximum 100 g per week.
0.04-0.1 mcg/kg IV three times weekly; titrate to serum calcium. Oral: 1-2 mcg daily or 0.5-1 mcg three times weekly.

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.
Terminal elimination half-life is 5–7 hours in healthy subjects; prolonged to 14–21 hours in patients with chronic kidney disease stage 5 on hemodialysis, reflecting reduced clearance.
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.
Primarily hepatobiliary (74% of absorbed dose recovered in feces as parent drug and metabolites); renal excretion accounts for approximately 16% (primarily as metabolites).
