Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vitamin D analog; binds to vitamin D receptors, increasing calcium absorption in intestines and promoting bone mineralization.
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.
Oral: 0.25-0.5 mcg once daily; titration up to 1 mcg daily based on serum calcium levels. Intravenous: 0.5-2 mcg bolus; maintenance 0.5-2 mcg daily.
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.

Terminal elimination half-life is approximately 20-30 hours; clinically, steady-state is achieved within 5-7 days.
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.
Primarily fecal (biliary) as unchanged drug and metabolites (approx. 80%); renal excretion accounts for less than 20%.
Primarily biliary/fecal; approximately 50% of dose recovered in feces within 24 hours. Renal excretion accounts for <5% of unchanged drug.
