CALCIBIND vs LANTHANUM CARBONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CALCIBIND (sodium polystyrene sulfonate) is a cation-exchange resin that exchanges sodium ions for potassium ions in the gastrointestinal tract, primarily in the colon, thereby reducing serum potassium levels.
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.
5 mg orally once daily, taken without food or with a low-fat meal.
Oral: 500-1000 mg three times daily with meals, titrated based on serum phosphate levels; maximum 3000 mg/day.

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 elimination half-life: 2-4 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (eGFR <30 mL/min), necessitating dose adjustment.
Terminal half-life not clinically defined due to minimal systemic absorption; effectively acts locally in GI tract.
Primarily renal (90% as unchanged drug via glomerular filtration and tubular secretion). Biliary/fecal: 10% (unabsorbed drug and metabolites).
Primarily fecal (>99%) as unabsorbed drug. Minimal renal elimination (<1%).
