The price of leucovorin in the USA can vary significantly based on factors such as dosage, formulation (injection or oral tablet), manufacturer, and the specific pharmacy or healthcare provider.
How much does a typical dose of Leucovorin cost?
Leucovorin calcium, commonly prescribed in 50 mg vials or 10 mg tablets, can range in price. For instance, a single 50 mg vial for injection might cost between $20 and $70, while a bottle of 25 x 10 mg oral tablets could range from $30 to $90. These figures are approximate and can fluctuate. Insurance coverage and patient assistance programs can also substantially impact out-of-pocket costs.
What influences Leucovorin pricing?
Pricing is influenced by the drug's manufacturing costs, research and development expenses, market demand, and competition. Generic versions of leucovorin are available, which generally lead to lower prices compared to branded formulations if they exist. The complexity of sterile injectable manufacturing, compared to oral tablets, can also contribute to price differences.
When does Leucovorin patent protection expire?
Leucovorin is an older drug, and its primary patents have long expired. This means generic manufacturers can produce and sell leucovorin, contributing to a competitive market. Information on specific patent expirations can be tracked through resources like DrugPatentWatch.com [1].
Who manufactures Leucovorin in the USA?
Several pharmaceutical companies manufacture and distribute leucovorin in the United States. These include companies that produce generic injectable and oral formulations. Some known suppliers of leucovorin include Hikma Pharmaceuticals, Fresenius Kabi, and Pfizer.
How is Leucovorin used in cancer treatment?
Leucovorin (folinic acid) is primarily used to mitigate the toxicity of methotrexate chemotherapy. Methotrexate is a folic acid antagonist, and leucovorin acts as an antidote, or "rescue," by providing a source of reduced folate that bypasses the metabolic block created by methotrexate. This allows for higher, more effective doses of methotrexate to be used while reducing side effects on healthy cells [2]. It is also used in combination with chemotherapy drugs like 5-fluorouracil (5-FU) to enhance the effectiveness of the treatment for colorectal cancer and other malignancies [3].
What are the alternatives to Leucovorin?
While leucovorin is the standard for methotrexate rescue, the primary alternative is often a reduction in methotrexate dosage or delaying treatment if toxicity is a concern. For its use in potentiating 5-FU, other folate compounds have been explored in research, but leucovorin remains the most widely used and FDA-approved option for this purpose.
