C-SOLVE-2 vs Calcium Carbonate / Calcium Supplements
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not specified in available data.
Calcium carbonate is a calcium salt that dissociates in the stomach to release calcium ions. Calcium is essential for nerve transmission, muscle contraction, blood coagulation, and bone mineralization. It acts as a cofactor for various enzymes and maintains cell membrane integrity and permeability.
10 mg intravenously every 12 hours.
1250 mg (500 mg elemental calcium) orally 1-2 times daily with meals; maximum 2500 mg elemental calcium per day.

Terminal half-life: 12 hours (range 10-14) in adults; prolonged to 24 hours in severe renal impairment (CrCl <30 mL/min).
Calcium's elimination half-life is approximately 2-4 hours for ionized calcium, with a slower terminal phase of 8-12 hours due to exchange from bone pools. Clinically, serum calcium levels normalize within 4-6 hours after a single dose.
Renal: 70% unchanged; hepatic metabolism: 20%; fecal: 10%.
Primarily renal (20-30% excreted as calcium), with the remainder reabsorbed in the renal tubules. Fecal excretion accounts for 70-80% of ingested calcium, representing unabsorbed calcium. Biliary excretion is negligible.
