LANTHANUM CARBONATE vs PHOSLYRA
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.
Phoslyra (calcium acetate) binds dietary phosphate in the gastrointestinal tract, forming insoluble calcium phosphate complexes that are excreted in the feces, thereby reducing serum phosphate levels.
Oral: 500-1000 mg three times daily with meals, titrated based on serum phosphate levels; maximum 3000 mg/day.
1330 mg (one caplet) orally three times daily with meals, titrated to achieve serum phosphorus within target range.

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; Phoslyra (calcium acetate) is not absorbed systemically; local effect in GI tract.
Primarily fecal (>99%) as unabsorbed drug. Minimal renal elimination (<1%).
Renal 100% as unchanged drug, no biliary or fecal elimination.
