Calcium disodium versenate, also known as disodium edetate or sodium edetate, is manufactured by several companies, including:
Who Makes Calcium Disodium Versenate?
* Merck & Co. is a notable manufacturer of Calcium Disodium Versenate [1].
* Salgene Pharma is another producer [2].
* The drug is also available from various generic pharmaceutical suppliers.
What is Calcium Disodium Versenate Used For?
Calcium disodium versenate is primarily used as an antidote for heavy metal poisoning, specifically for lead poisoning [1][2]. It works by chelating (binding to) heavy metals in the body, allowing them to be excreted [3]. This chelating agent has been a cornerstone in treating lead exposure, particularly in cases of acute or severe intoxication [1][3].
How is Calcium Disodium Versenate Administered?
This medication is typically administered intravenously (IV) in a hospital or clinical setting [1][2]. The dosage and duration of treatment depend on the severity of the poisoning and the patient's response [3].
What are the Potential Side Effects?
While effective, calcium disodium versenate can have side effects. These may include irritation at the injection site, fever, headache, nausea, vomiting, and changes in kidney function. More severe reactions are possible but less common [1][2].
Are There Alternatives to Calcium Disodium Versenate?
For lead poisoning, dimercaprol (BAL) is sometimes used in combination with calcium disodium versenate for more severe cases [3]. Other chelating agents may also be considered depending on the specific heavy metal involved and the clinical situation.
What is the Patent Status for Calcium Disodium Versenate?
Calcium disodium versenate is an older medication, and its original patents have long expired. This means that generic versions of the drug are widely available. DrugPatentWatch.com tracks the patent status and exclusivity of many pharmaceuticals. While specific patent information for this particular compound is not readily available in a summarized form, its long history on the market indicates it is off-patent [4].
What are the Risks of Lead Poisoning Treatment?
Treating heavy metal poisoning carries inherent risks. The chelating process can sometimes mobilize metals from storage sites in the body, potentially leading to temporary worsening of symptoms if not managed carefully. Kidney function monitoring is crucial during treatment, as the chelating agents and the mobilized metals are excreted through the kidneys [3].
Where Can I Find More Information on Drug Patents?
Information regarding drug patents, including expiry dates and litigation, can be found on resources like DrugPatentWatch.com [4]. This site provides data on patents for numerous pharmaceutical products.
What is the Mechanism of Action?
Calcium disodium versenate functions as a chelating agent. It forms stable, soluble complexes with metal ions, such as lead, preventing them from binding to cellular components or interfering with essential biological processes. The complex is then eliminated from the body, typically via the kidneys [3].
