DELTALIN vs PARICALCITOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vitamin D analog; binds to vitamin D receptors, increasing intestinal absorption of calcium and phosphate, promoting renal tubular reabsorption of calcium, and enhancing bone mineralization.
Paricalcitol is a synthetic vitamin D analog that binds to the vitamin D receptor (VDR) in target tissues, including the parathyroid glands, kidneys, and intestines. It selectively activates VDR to suppress parathyroid hormone (PTH) secretion, reduce parathyroid cell proliferation, and modulate calcium and phosphate homeostasis with lower calcemic and phosphatemic effects compared to calcitriol.
0.5 mg orally once daily, titrated to a maximum of 1 mg daily based on response and tolerability.
0.04 to 0.1 mcg/kg intravenously bolus no more frequently than every other day during dialysis, or 1 to 4 mcg orally once daily.

Clinical Note
moderateParicalcitol + Digoxin
"The risk or severity of adverse effects can be increased when Paricalcitol is combined with Digoxin."
Clinical Note
moderateParicalcitol + Hydrochlorothiazide
"Paricalcitol may increase the hypercalcemic activities of Hydrochlorothiazide."
Clinical Note
moderateParicalcitol + Bendroflumethiazide
"Paricalcitol may increase the hypercalcemic activities of Bendroflumethiazide."
Clinical Note
moderateParicalcitol + Methyclothiazide
Terminal elimination half-life ranges from 24 to 36 hours in adults with normal renal function; may be prolonged (up to 72 hours) in renal impairment.
Terminal elimination half-life is approximately 5-7 hours in healthy subjects, but may be prolonged to 14-20 hours in patients with renal impairment.
Renal excretion of unchanged drug accounts for approximately 60-70% of the administered dose; biliary/fecal elimination accounts for 30-40%, primarily as metabolites.
Primarily fecal (74%) via hepatobiliary excretion; renal elimination accounts for approximately 16% as unchanged drug.
