CALCIPOTRIENE AND BETAMETHASONE DIPROPIONATE vs VECTICAL
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.
VECTICAL (calcitriol) is a vitamin D analog that binds to vitamin D receptors (VDRs) in target tissues, increasing intestinal calcium absorption, renal calcium reabsorption, and enhancing osteoclast activity to mobilize calcium from bone, thereby raising serum calcium levels.
Apply once daily to affected areas of skin, not exceeding 100 g/week or 30 mL/day. Do not use under occlusive dressings.
1-2 mcg orally twice daily, increased every 2-4 weeks based on serum calcium and PTH levels. Maximum dose: 4 mcg twice daily.

Calcipotriene: 12-24 hours; betamethasone dipropionate: 4-6 hours (parent), 3-5 hours (active metabolite betamethasone 17-propionate).
Mean terminal elimination half-life is approximately 3.7 hours (range 2.5–5.5 hours) in healthy adults. Clinically, steady-state is achieved within 2–3 days.
Calcipotriene: renal elimination of metabolites; betamethasone dipropionate: primarily renal (70%) and biliary/fecal (30%) as metabolites.
Primarily hepatobiliary (74%) and fecal (14%), with renal excretion accounting for <1% of the administered dose as unchanged drug. Enterohepatic recirculation occurs.
