CALCIPOTRIENE AND BETAMETHASONE DIPROPIONATE vs ROCALTROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Calcipotriene is a synthetic vitamin D3 analog that binds to vitamin D receptors, regulating cell proliferation and differentiation. Betamethasone dipropionate is a corticosteroid that reduces inflammation by inducing phospholipase A2 inhibitory proteins (lipocortins), inhibiting arachidonic acid release, and decreasing prostaglandin and leukotriene synthesis.
Calcitriol, the active form of vitamin D, binds to vitamin D receptors in target tissues, increasing intestinal absorption of calcium and phosphate, promoting renal tubular reabsorption of calcium, and stimulating bone mineralization.
Apply once daily to affected areas of skin, not exceeding 100 g/week or 30 mL/day. Do not use under occlusive dressings.
Oral, 0.25 mcg once daily; may increase to 0.5 mcg once daily based on response. Typical adult dose is 0.25-0.5 mcg/day.

Calcipotriene: 12-24 hours; betamethasone dipropionate: 4-6 hours (parent), 3-5 hours (active metabolite betamethasone 17-propionate).
Terminal elimination half-life is approximately 25–35 hours after oral administration. Clinical context: Once-weekly or thrice-weekly dosing achieves steady state in 1–2 weeks.
Calcipotriene: renal elimination of metabolites; betamethasone dipropionate: primarily renal (70%) and biliary/fecal (30%) as metabolites.
Primarily biliary/fecal; approximately 50% of dose recovered in feces within 24 hours. Renal excretion accounts for <5% of unchanged drug.
