High serum phosphorus concentrations are correlated with higher mortality and this is presumably the consequence of tissue calcification, particularly vascular calcification. It therefore helps prevent these problems. It is typically given to patients with advanced chronic kidney disease, including those receiving dialysis. Seventeen of the 38 patients in Group 2 required supplemental calcium, administered as cal-cium carbonate in a dose of 1.7 0.75 g of elemental calcium per day. Calcium carbonate is used as a phosphate binder in kidney failure to reduce the amount of phosphate absorbed from the gut. Calcium carbonate is widely used as an oral phosphorus binder to control hyperphosphatemia in children on maintenance hemodialysis. their phosphate binder. In period 2, they took no phosphate binders for a month, and in period 3, they took calcium carbonate (Os-Cal) for two months (mean dose, 8.5 g per day; range, 2.5 to 17). This controlled randomized, investigator-masked, multicentre trial Peak plasma time: 20-60 min (fasting state); up to 3 hr (ingested 1 hr after meals) Distribution. Calcium acetate/magnesium carbonate (CaMg) is a combination phosphate binder. Phosphate binder: Binds with dietary phosphate to form insoluble calcium phosphate, which is excreted in feces. Non-calcium-based phosphate binders (NCBPB), sevelamer and lanthanum, are costlier but do not cause hypercalcemia [ 8 – 11 ]. This can cause renal bone disease. Calcium carbonate as a phosphate binder in patients with chronic renal failure undergoing dialysis. In one study of the use of calcium carbonate as a phosphate binder in patients on chronic hemodialysis, there was a low incidence of hypercalcemia at daily doses below 6 g [2], whereas in another report on 26 dialysis patients who used calcium carbonate for 3 years, 42% developed new calcification [3]. Group I and 2 patients treated with vitamin D were maintained on this therapy. The effect of a high intake of calcium carbonate in normal subjects and patients with chronic renal failure. SETTING: This study involved outpatient hemodialysis. Calcium—delivered as calcium acetate, calcium citrate or calcium carbonate—is less expensive, but more likely to cause hypercalcemia [8–11]. Participants: We recruited 30 stable hemodialysis patients without a history of frequent diarrhea. Both components separately or magnesium carbonate together with calcium carbonate are already well-established phosphate-lowering agents . One may avoid these adverse effects by using phosphate binders that do not contain calcium or aluminium as active ingredients , such as lanthanum carbonate or sevelamer . Setting: This study involved outpatient hemodialysis. 6 This is primarily because emerging evidence suggests calcium-based binders may accelerate vascular calcification and cardiovascular mortality. The comparison of the measured and theoretical quantities of phosphate adsorbed onto 1 g of the ingredient in combination with each phosphate binder and calcium carbonate at … The effects of calcium carbonate as the sole phosphate binder in combination with low calcium dialysate and calcitriol therapy in chronic hemodialysis patients. After 15-week progression, calcium carbonate (3.0%), sevelamer-HCl (3.0%), or control diets (0.3% calcium) were given for 9 weeks. Preclinical and clinical studies have shown a good safety profile, and it appears to be well tolerated and effective in reducing phosphate levels in dialysis patients; however, it is similarly expensive. Recently, two iron-based phosphate binders have been approved. Absorption. Scope: A literature search was performed using MEDLINE and EMBASE … A phosphate binder combining calcium and magnesium offers an interesting therapeutic option. Intestinal calcium absorption may induce hypercalcemia, particularly if calcitriol is given simultaneously. Intervention: After receiving informed consent, we randomized patients 2:1 to magnesium carbonate versus calcium acetate. Phosphate binders are required to control serum phosphorus in dialysis patients. Author information: (1)Emory University School of Medicine, Atlanta, GA. Three major classes of phosphate binders include calcium-based binders, sevelamer HCl, and lanthanum carbonate. Organs and systems Mineral balance. Protein bound: 45% Primary and Secondary Outcomes The efficacy of a magnesium carbonate/calcium carbonate combination tablet as a phosphate binder. carbonate versus calcium acetate as a sole phosphate binder. Lanthanum carbonate is another non-aluminum, calcium-free phosphate binder. The first phosphate binders were aluminum- and magnesium-based antacids. Calcium carbonate is the most commonly used phosphate binder, but clinicians are increasingly prescribing the more expensive, non-calcium-based phosphate binders, particularly sevelamer. Phosphate-binding capacity of coadministered calcium carbonate and other phosphate binders. Our aim was to compare the effects of calcium carbonate and sevelamer-HCl treatments on calcium-phosphate metabolism and renal function in 5/6 nephrectomized (NX) rats so that long-term disease progression preceded the treatment. All patients were instructed to ingest phosphate binders with meals. Manufacturer advises that other drugs should be taken at least 2 hours before or 3 hours after calcium acetate with magnesium carbonate to reduce possible interference with absorption of other drugs. This tablet was compared to calcium acetate (previous binder dose). Patient and carer advice. To study the effects of calcium carbonate preparations with different dissolution characteristics on the incidence of this side effect, we conducted a double-blind, crossover trial in 21 patients undergoing chronic haemodialysis. The rationale for the use of phosphate binders is to transform phosphate in the food into a non-absorbable form, reducing the risk of soft-tissue calcification. Calcium carbonate powder (CalCarb-HD, 2.4 gms elemental calcium/packet) (CalCarb-HD, Lafayette Pharmacal Inc., Fort Worth, TX) was used in the study. DESIGN: This study was a prospective, randomized, open-label trial comparing magnesium carbonate/calcium carbonate versus calcium acetate as a sole phosphate binder. Clin Sci. If calcium is already being used as a supplement, additional calcium used as a phosphate binder may cause hypercalcemia and tissue-damaging calcinosis. There are many others, usually containing calcium carbonate. Excess calcium from supplements, fortified food, and high-calcium diets can cause milk-alkali syndrome , which has serious toxicity and can be fatal. solution + the other phosphate binder + phosphate solu-tion), (5) combination (calcium carbonate + the other phosphate binder + phosphate solution). Calcium carbonate is the most commonly used phosphate binder, but clinicians are increasingly prescribing the more expensive, non-calcium-based phosphate binders, particularly sevelamer. Calcium acetate is used as an oral phosphate binder to control hyperphos-phatemia in patients with chronic renal failure. Calcium carbonate has been successfully used as a phosphate binder in patients with chronic renal failure; however, a high frequency of hypercalcaemia has been reported. In Meyler's Side Effects of Drugs (Sixteenth Edition), 2016. In adults, calcium acetate binds phosphorus more effectively than calcium carbonate, while reducing the frequency of hypercalcemic events. Calcium acetate is a more effective phosphate binder on a weight basis (presumably it is effective at a wider pH range than calcium carbonate) and may be less often associated with hypercalcemia [276,277]. Effect of coadministration of each phosphate binder and calcium carbonate on serum phosphorus level after administration of phosphate solution to rats Male SD rats were fasted for approximately 16h and Abstract; Slatapolsky E, Weerts C, Lopez-Hilker S, et al. Tums is a form of calcium carbonate, which can also be effective. At this institution, calcium carbonate powder as a phosphate binder, examination of its efficacy, and the frequency of hypercalcemia with its use were of great interest. Calcium acetate, also called PhosLo, is one commonly used phosphorus binder. In all, exposure to calcium and the incidence of hypercalcemia were less in the calcium acetate arm. Calcium carbonate as phosphate binder. Phosphate binders that contain aluminum are frequently prescribed to treat hyperphosphatemia in patients with chronic renal failure, but an accumulation of aluminum can lead to osteomalacia. OBJECTIVE: This study was designed to evaluate the efficacy of magnesium carbonate as a phosphate binder in hemodialysis patients. Apart from longer or more frequent dialysis sessions, the only possible alternative is to reduce phosphorus absorption in the gut. Adverse effects and toxicity limited the use of these agents, and therapy evolved with calcium carbonate, calcium acetate, sevelamer, and lanthanum carbonate. ThePBCofcalciumcarbonateis 39mgPO 4 per1gof Magnesium carbonate (86 mg of elemental magnesium) and calcium carbonate (100 mg of elemental calcium) were in the combination tablet. Many nephrologists feel threatened by the allegation that, in patients with chronic renal failure, treatment with calcium-based phosphate binders (calcium acetate and calcium carbonate) may induce coronary artery and cardiac calcification, thereby imposing a greater risk for death compared with sevelamer, a non–calcium-based binder. Some products that may interact with this drug include: digoxin, certain phosphate binders (such as calcium acetate), phosphate supplements (such as potassium phosphate), sodium … Bioavailability: 25-35%; food increases absorption 10-30%; antacid action dependent on gastric emptying time. Abstract. 1966;30:425-438. As with all phosphate binders, calcium-based binders are most effective when taken with meals (which also limits Drinking full glass (8 ounces) of water or juice with all oral dosage forms, except when taking calcium carbonate as a phosphate binder in renal dialysis » Proper administration of calcium carbonate or phosphate: Taking tablets 1 to 11/2 hours after meals, unless otherwise directed by physician Oettinger CW(1), Oliver JC, Macon EJ. Calcium carbonate is the most common form of phosphate binder prescribed, particularly in non-dialysis chronic kidney disease. Calcium-based phosphorus binders have largely replaced aluminum-based binders and may also serve as calcium supplements. Calcium Acetate. Background: Obstacles to successful management of hyperphosphatemia in chronic kidney disease include inadequate control of dietary phosphate and non-compliance with phosphate-binder therapy. Calcium carbonate or calcium acetates are the most widely used phosphate binders in Europe. calcium carbonate with calcium acetate as a phosphate binder.31-33 In these cases, calcium acetate was equally effective or more effective in lowering serum PO 4 levels when compared to calcium acetate.
