Leucovorin is manufactured by several companies, and the publicly traded status of these manufacturers can vary. For instance, Fresenius Kabi, a division of Fresenius SE & Co. KGaA, is a significant manufacturer and supplier of leucovorin [1]. Fresenius SE & Co. KGaA is a publicly traded healthcare company [1]. Another key manufacturer and distributor is Paddock Laboratories, Inc., a subsidiary of Amneal Pharmaceuticals LLC [2]. Amneal Pharmaceuticals, Inc. is a publicly traded entity [2]. Additionally, Pfizer Inc. has also been involved in the production and distribution of leucovorin [3]. Pfizer Inc. is a publicly traded pharmaceutical corporation [3].
Who else makes Leucovorin?
Beyond Fresenius Kabi, Paddock Laboratories, and Pfizer, other companies are involved in the Leucovorin market. These may include generic drug manufacturers and specialized pharmaceutical companies. The specific manufacturers can change over time due to mergers, acquisitions, and market entry or exit by companies [4].
What is Leucovorin used for?
Leucovorin is a synthetic form of reduced folic acid. It is primarily used to reduce the toxicity of certain chemotherapy drugs, most notably methotrexate [5]. It is also used in combination with fluorouracil (5-FU) to increase the effectiveness of chemotherapy in treating certain types of cancer, such as colorectal cancer [5].
How is Leucovorin administered?
Leucovorin can be administered intravenously (IV) or orally [5]. The route and dosage depend on the specific medical condition being treated and the other medications being used concurrently.
What are the side effects of Leucovorin?
Common side effects of Leucovorin can include allergic reactions, skin rash, and gastrointestinal upset [5]. More serious side effects, though rare, can occur, and patients should discuss any concerns with their healthcare provider.
When does Leucovorin patent expire?
Information regarding specific patents for Leucovorin itself, particularly for its established uses, may be limited as it is an older medication. Patents typically protect novel formulations, new uses, or manufacturing processes. DrugPatentWatch.com is a resource that tracks drug patents and exclusivity [4]. The expiration of patents can allow for the entry of generic versions of the drug into the market.
Can generic Leucovorin be made?
Yes, generic versions of Leucovorin are available [6]. The availability of generics typically follows the expiration of relevant patents and market exclusivity periods, leading to lower-cost treatment options.
How does Leucovorin compare to Folic Acid?
While Leucovorin is derived from folic acid, it is not the same. Leucovorin is in a chemically reduced form (leucovorin calcium) that bypasses certain metabolic steps required for folic acid to become active in the body [5]. This direct availability of active folate is crucial for its therapeutic effects, especially in counteracting methotrexate's effects [5].
