LANTHANUM CARBONATE vs RENAGEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lanthanum carbonate dissociates in the acidic gastric environment to release lanthanum ions, which bind to dietary phosphate in the gastrointestinal tract, forming insoluble lanthanum-phosphate complexes that are excreted in feces, reducing serum phosphate levels.
Sevelamer is a phosphate-binding polymer that binds dietary phosphate in the gastrointestinal tract, preventing its absorption and reducing serum phosphate levels.
Oral: 500-1000 mg three times daily with meals, titrated based on serum phosphate levels; maximum 3000 mg/day.
Initial dose: 800-1600 mg orally three times daily with meals. Titrate by 1 tablet/capsule per meal based on serum phosphorus levels. Maintenance: typically 2-4 tablets/capsules per meal.

Clinical Note
moderateLanthanum carbonate + Gatifloxacin
"The serum concentration of Gatifloxacin can be decreased when it is combined with Lanthanum carbonate."
Clinical Note
moderateLanthanum carbonate + Rosoxacin
"The serum concentration of Rosoxacin can be decreased when it is combined with Lanthanum carbonate."
Clinical Note
moderateLanthanum carbonate + Levofloxacin
"The serum concentration of Levofloxacin can be decreased when it is combined with Lanthanum carbonate."
Clinical Note
moderateTerminal half-life not clinically defined due to minimal systemic absorption; effectively acts locally in GI tract.
Not applicable (non-absorbable polymer; systemic absorption <0.01%).
Primarily fecal (>99%) as unabsorbed drug. Minimal renal elimination (<1%).
Renal: 0%; Fecal: >99% (as intact drug, due to non-absorbable polymer). Biliary: negligible.
