What is leucovorin used for?
Leucovorin is used in combination with certain chemotherapy drugs, such as fluorouracil, to treat colorectal cancer. It is also used to reduce the toxicity of methotrexate, a chemotherapy drug, and to restore the bone marrow and gastrointestinal tissue after high doses of methotrexate. Additionally, it can be used to treat megaloblastic anemia caused by folate deficiency [3].
What is the difference between leucovorin and folic acid?
Leucovorin is a reduced form of folic acid, also known as folinic acid. While both are related to folate metabolism, leucovorin is an active form that can directly enter biochemical pathways without needing to be converted from folic acid. This makes it particularly useful in specific medical treatments where rapid or direct folate activity is required, such as in counteracting methotrexate's effects or enhancing fluorouracil's efficacy [3].
When does leucovorin go off patent?
Information regarding the patent status of leucovorin can be complex, as it has been around for a significant period.
