Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcitriol, the active form of vitamin D, binds to the vitamin D receptor (VDR) in target tissues, increasing intestinal absorption of calcium and phosphate, promoting renal tubular reabsorption of calcium, and stimulating bone resorption. It also suppresses parathyroid hormone (PTH) synthesis and secretion via negative feedback.
Calcipotriene is a synthetic vitamin D3 analog that binds to vitamin D receptors (VDR) and suppresses keratinocyte proliferation while inducing differentiation. Betamethasone dipropionate is a potent corticosteroid that binds to glucocorticoid receptors, inhibiting pro-inflammatory mediators and reducing inflammation, pruritus, and vasodilation.
Intravenous: 0.5 mcg three times per week during dialysis; may be increased by 0.25-0.5 mcg at 2-4 week intervals. Oral: 0.25 mcg daily; may be increased to 0.5 mcg daily.
Apply to affected areas once daily; maximum weekly dose should not exceed 100 g (calcipotriene 0.005% and betamethasone dipropionate 0.064% as combination ointment or foam).

Terminal elimination half-life ranges from 5 to 10 hours in patients with normal renal function. In renal impairment, half-life may be prolonged up to 20 hours or more.
Calcipotriene: not applicable due to minimal systemic exposure. Betamethasone dipropionate: terminal half-life of betamethasone after topical application is approximately 5-6 hours.
Primarily hepatic (biliary-fecal) elimination; approximately 2-4% excreted unchanged in urine. Small amount undergoes enterohepatic recirculation.
Calcipotriene: negligible systemic absorption; absorbed fraction undergoes hepatic metabolism and is excreted in feces (approx. 70%) and urine (approx. 20%). Betamethasone dipropionate: absorbed dose metabolized in liver, metabolites excreted primarily in urine (60-70%) and feces (20-30%).
