LANTHANUM CARBONATE vs PHOSLO GELCAPS
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.
Calcium acetate binds dietary phosphate in the gastrointestinal tract, forming insoluble calcium phosphate complexes that are excreted in 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.
Oral: One to two capsules (668-1336 mg calcium acetate) three times daily with meals, titrated to maintain serum phosphate between 3.5-5.5 mg/dL, maximum 4 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; calcium is a physiologic ion with dynamic regulation; steady-state serum calcium is maintained by homeostatic mechanisms. In overdose, serum calcium half-life is approximately 3-4 hours.
Primarily fecal (>99%) as unabsorbed drug. Minimal renal elimination (<1%).
Primarily fecal as unabsorbed calcium; renal excretion accounts for <1% of absorbed dose proportional to glomerular filtration rate.
