LANTHANUM CARBONATE vs SEVELAMER HYDROCHLORIDE
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 hydrochloride is a phosphate-binding polymer that binds dietary phosphate in the gastrointestinal tract, preventing its absorption and thereby 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 800 mg per meal at 2-week intervals based on serum phosphorus levels. Maintenance: typically 2.4-4.8 g/day divided with meals.

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; sevelamer is not absorbed. The polymer acts locally in the gastrointestinal tract and does not have a measurable plasma half-life.
Primarily fecal (>99%) as unabsorbed drug. Minimal renal elimination (<1%).
Sevelamer hydrochloride is not absorbed systemically; it is eliminated entirely in the feces as the unchanged polymer. No renal or biliary elimination occurs.
