Calcium acetate is a medication used to control high phosphate levels in the blood of people with chronic kidney disease [1]. It is available for purchase through various pharmaceutical suppliers and online pharmacies.
How does calcium acetate work to lower phosphate?
Calcium acetate acts as a phosphate binder. When taken with meals, it binds to dietary phosphate in the gastrointestinal tract, preventing its absorption into the bloodstream [1]. This binding action helps reduce the overall phosphate levels in patients with chronic kidney disease.
Where can I buy calcium acetate?
Calcium acetate is typically prescribed by a healthcare provider. It can be purchased from most retail pharmacies with a prescription. It is also available from wholesale pharmaceutical distributors that supply hospitals and clinics [2]. Online pharmacies also offer calcium acetate, but it is essential to ensure they are reputable and require a valid prescription.
What are the different forms and dosages of calcium acetate?
Calcium acetate is commonly available in tablet and capsule forms [1]. The dosage varies depending on the individual patient's needs and is determined by their physician. It is crucial to follow the prescribed dosage instructions carefully.
Are there alternatives to calcium acetate for managing high phosphate?
Other phosphate binders are available, including sevelamer, lanthanum carbonate, and ferric citrate [3]. The choice of phosphate binder may depend on factors such as efficacy, cost, side effect profile, and patient tolerance. Some newer agents like mogرودol are also in development [4].
What is the typical price range for calcium acetate?
The price of calcium acetate can vary based on the brand, dosage, quantity, and the pharmacy or supplier. Generic calcium acetate is generally more affordable than branded versions. Prices can range from under $10 to over $50 for a typical prescription supply, with insurance coverage often reducing out-of-pocket costs [5].
What are the potential side effects of calcium acetate?
Common side effects of calcium acetate can include gastrointestinal issues such as constipation, nausea, and vomiting [1]. Hypercalcemia, or high calcium levels in the blood, is also a potential risk, especially if calcium intake from other sources is high. Patients should report any concerning side effects to their doctor.
Are there any drug interactions to be aware of with calcium acetate?
Calcium acetate can interact with other medications, potentially affecting their absorption. It is advisable to separate the administration of calcium acetate from certain drugs, such as tetracyclines, fluoroquinolones, and bisphosphonates, by at least two hours [1]. Always inform your healthcare provider about all medications you are taking.
What is the patent status of calcium acetate?
Calcium acetate is a long-established medication, and its primary patents have expired [6]. This means that generic versions of calcium acetate are widely available from multiple manufacturers, contributing to its affordability.
How does calcium acetate compare to other phosphate binders?
Compared to some other phosphate binders, calcium acetate is generally considered effective and cost-efficient [3]. However, it carries a higher risk of hypercalcemia. Sevelamer, for example, does not contain calcium and may have a different gastrointestinal side effect profile. Lanthanum carbonate offers another non-calcium-based option.
