Calcium (Calcium Carbonate):
Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).
- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)
The recommended initial dose of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.
- Starting dose is 2 capsules with each meal. (2)
- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)
Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate capsule.
- Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate capsule. (3)
Patients with hypercalcemia.
- Hypercalcemia. (4)
- Treat mild hypercalcemia by reducing or interrupting Calcium; Vitamin D3 ) acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate. (5.1)
- Hypercalcemia may aggravate digitalis toxicity. (5.2)
Patients with end stage renal disease may develop hypercalcemia when treated with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)), including Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate. Avoid the use of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) supplements, including Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) based nonprescription antacids, concurrently with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate.
An overdose of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) levels twice weekly. Should hypercalcemia develop, reduce the Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia
More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate therapy.
Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.
Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate on the progression of vascular or soft tissue calcification has not been determined.
Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.
Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.
Hypercalcemia may aggravate digitalis toxicity.
Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].
- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)
- In clinical studies, patients have occasionally experienced nausea during Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate therapy. (6)

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical studies, Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate has been generally well tolerated.
Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.
Preferred Term | Total adverse reactions reported for Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate N=167 N (%) | 3 month, open label study of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate N=98 N (%) | Double blind, placebo-controlled, cross-over study of liquid Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate N=69 | |

Hypercalcemia | 21 (12.6) | 16 (16.3) | 5 (7.2) | 0 (0) |
Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) concentration could reduce the incidence and severity of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.
The following additional adverse reactions have been identified during post-approval of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate: dizziness, edema, and weakness.
The drug interaction of Calcium; Vitamin D3 ) acetate is characterized by the potential of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.
There are no empirical data on avoiding drug interactions between Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate and most concomitant drugs. When administering an oral medication with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate.
- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)
- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate or consider monitoring blood levels of the drug. (7)
In a study of 15 healthy subjects, a co-administered single dose of 4 Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.
Pregnancy Category C:
Calcium; Vitamin D3 ) acetate capsules contains Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate. Animal reproduction studies have not been conducted with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate, and there are no adequate and well controlled studies of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate treatment, as recommended, is not expected to harm a fetus if maternal Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) levels are properly monitored during and following treatment.
The effects of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate on labor and delivery are unknown.
Calcium; Vitamin D3 ) Acetate Capsules contains Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate and is excreted in human milk. Human milk feeding by a mother receiving Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate is not expected to harm an infant, provided maternal serum Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) levels are appropriately monitored.
Safety and effectiveness in pediatric patients have not been established.
Clinical studies of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Administration of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].
Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate acts as a phosphate binder. Its chemical name is Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate. Its molecular formula is C4H6CaO4, and its molecular weight is 158.17. Its structural formula is:
Each white opaque/blue opaque capsule contains 667 mg of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Calcium; Vitamin D3 (Calcium (Calcium Carbonate)), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.
Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.
Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Calcium; Vitamin D3 ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.
Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.
Orally administered Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.
No carcinogenicity, mutagenicity, or fertility studies have been conducted with Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate.
Effectiveness of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate solid oral dosage form.
Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.
The patients received Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.
The data presented in Table 2 demonstrate the efficacy of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) increased 9% during the study mostly in the first month of the study.
Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.
The phosphate binding effect of Calcium; Vitamin D3 (Calcium (Calcium Carbonate)) acetate is shown in the Table 3.

Calcium (Calcium Fumarate):
Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).
- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)
The recommended initial dose of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.
- Starting dose is 2 capsules with each meal. (2)
- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)
Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate capsule.
- Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate capsule. (3)
Patients with hypercalcemia.
- Hypercalcemia. (4)
- Treat mild hypercalcemia by reducing or interrupting Calcium; Vitamin D3 ) acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate. (5.1)
- Hypercalcemia may aggravate digitalis toxicity. (5.2)
Patients with end stage renal disease may develop hypercalcemia when treated with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)), including Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate. Avoid the use of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) supplements, including Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) based nonprescription antacids, concurrently with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate.
An overdose of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) levels twice weekly. Should hypercalcemia develop, reduce the Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia
More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate therapy.
Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.
Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate on the progression of vascular or soft tissue calcification has not been determined.
Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.
Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.
Hypercalcemia may aggravate digitalis toxicity.
Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].
- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)
- In clinical studies, patients have occasionally experienced nausea during Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate therapy. (6)

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical studies, Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate has been generally well tolerated.
Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Hypercalcemia | 21 (12.6) | 16 (16.3) | 5 (7.2) | 0 (0) |
Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) concentration could reduce the incidence and severity of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.
The following additional adverse reactions have been identified during post-approval of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate: dizziness, edema, and weakness.
The drug interaction of Calcium; Vitamin D3 ) acetate is characterized by the potential of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.
There are no empirical data on avoiding drug interactions between Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate and most concomitant drugs. When administering an oral medication with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate.
- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)
- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate or consider monitoring blood levels of the drug. (7)
In a study of 15 healthy subjects, a co-administered single dose of 4 Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.
Pregnancy Category C:
Calcium; Vitamin D3 ) acetate capsules contains Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate. Animal reproduction studies have not been conducted with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate, and there are no adequate and well controlled studies of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate treatment, as recommended, is not expected to harm a fetus if maternal Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) levels are properly monitored during and following treatment.
The effects of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate on labor and delivery are unknown.
Calcium; Vitamin D3 ) Acetate Capsules contains Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate and is excreted in human milk. Human milk feeding by a mother receiving Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate is not expected to harm an infant, provided maternal serum Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) levels are appropriately monitored.
Safety and effectiveness in pediatric patients have not been established.
Clinical studies of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Administration of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].
Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate acts as a phosphate binder. Its chemical name is Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate. Its molecular formula is C4H6CaO4, and its molecular weight is 158.17. Its structural formula is:
Each white opaque/blue opaque capsule contains 667 mg of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Calcium; Vitamin D3 (Calcium (Calcium Fumarate)), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.
Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.
Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Calcium; Vitamin D3 ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.
Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.
Orally administered Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.
No carcinogenicity, mutagenicity, or fertility studies have been conducted with Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate.
Effectiveness of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate solid oral dosage form.
Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.
The patients received Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.
The data presented in Table 2 demonstrate the efficacy of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) increased 9% during the study mostly in the first month of the study.
Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.
The phosphate binding effect of Calcium; Vitamin D3 (Calcium (Calcium Fumarate)) acetate is shown in the Table 3.

Calcium (Calcium Malate):
Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).
- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)
The recommended initial dose of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.
- Starting dose is 2 capsules with each meal. (2)
- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)
Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate capsule.
- Capsule: 667 mg Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate capsule. (3)
Patients with hypercalcemia.
- Hypercalcemia. (4)
- Treat mild hypercalcemia by reducing or interrupting Calcium; Vitamin D3 ) acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate. (5.1)
- Hypercalcemia may aggravate digitalis toxicity. (5.2)
Patients with end stage renal disease may develop hypercalcemia when treated with Calcium; Vitamin D3 (Calcium (Calcium Malate)), including Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate. Avoid the use of Calcium; Vitamin D3 (Calcium (Calcium Malate)) supplements, including Calcium; Vitamin D3 (Calcium (Calcium Malate)) based nonprescription antacids, concurrently with Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate.
An overdose of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Calcium; Vitamin D3 (Calcium (Calcium Malate)) levels twice weekly. Should hypercalcemia develop, reduce the Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia
More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate therapy.
Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.
Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate on the progression of vascular or soft tissue calcification has not been determined.
Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.
Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg2/dL2.
Hypercalcemia may aggravate digitalis toxicity.
Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].
- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)
- In clinical studies, patients have occasionally experienced nausea during Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate therapy. (6)

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical studies, Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate has been generally well tolerated.
Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Calcium; Vitamin D3 (Calcium (Calcium Malate)) concentration could reduce the incidence and severity of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.
The following additional adverse reactions have been identified during post-approval of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate: dizziness, edema, and weakness.
The drug interaction of Calcium; Vitamin D3 ) acetate is characterized by the potential of Calcium; Vitamin D3 (Calcium (Calcium Malate)) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.
There are no empirical data on avoiding drug interactions between Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate and most concomitant drugs. When administering an oral medication with Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate.
- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)
- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate or consider monitoring blood levels of the drug. (7)
In a study of 15 healthy subjects, a co-administered single dose of 4 Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.
Pregnancy Category C:
Calcium; Vitamin D3 ) acetate capsules contains Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate. Animal reproduction studies have not been conducted with Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate, and there are no adequate and well controlled studies of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Calcium; Vitamin D3 (Calcium (Calcium Malate)) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate treatment, as recommended, is not expected to harm a fetus if maternal Calcium; Vitamin D3 (Calcium (Calcium Malate)) levels are properly monitored during and following treatment.
The effects of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate on labor and delivery are unknown.
Calcium; Vitamin D3 ) Acetate Capsules contains Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate and is excreted in human milk. Human milk feeding by a mother receiving Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate is not expected to harm an infant, provided maternal serum Calcium; Vitamin D3 (Calcium (Calcium Malate)) levels are appropriately monitored.
Safety and effectiveness in pediatric patients have not been established.
Clinical studies of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Administration of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].
Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate acts as a phosphate binder. Its chemical name is Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate. Its molecular formula is C4H6CaO4, and its molecular weight is 158.17. Its structural formula is:
Each white opaque/blue opaque capsule contains 667 mg of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Calcium; Vitamin D3 (Calcium (Calcium Malate)), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.
Calcium; Vitamin D3 (Calcium (Calcium Malate)) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.
Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Calcium; Vitamin D3 ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.
Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Calcium; Vitamin D3 (Calcium (Calcium Malate)) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.
Orally administered Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.
No carcinogenicity, mutagenicity, or fertility studies have been conducted with Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate.
Effectiveness of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate solid oral dosage form.
Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.
The patients received Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.
The data presented in Table 2 demonstrate the efficacy of Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Calcium; Vitamin D3 (Calcium (Calcium Malate)) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Calcium; Vitamin D3 (Calcium (Calcium Malate)) increased 9% during the study mostly in the first month of the study.
Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Calcium; Vitamin D3 (Calcium (Calcium Malate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Calcium; Vitamin D3 (Calcium (Calcium Succinate)) increased 9% during the study mostly in the first month of the study.
Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Calcium; Vitamin D3 (Calcium (Calcium Succinate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.
The phosphate binding effect of Calcium; Vitamin D3 (Calcium (Calcium Succinate)) acetate is shown in the Table 3.
