Leucovorin calcium, a reduced folate derivative, is a critical adjunct in chemotherapy regimens and treats folate deficiencies. Its market is characterized by established therapeutic uses, generic competition, and ongoing research for novel applications, influencing its financial trajectory.
What is the primary therapeutic use of Leucovorin Calcium?
Leucovorin calcium's primary therapeutic use is as a rescue agent following high-dose methotrexate (MTX) chemotherapy. Methotrexate is a folate antagonist, and high doses can lead to severe toxicity to bone marrow and gastrointestinal mucosa. Leucovorin calcium bypasses the enzymatic block caused by MTX, supplying cells with reduced folate necessary for DNA synthesis, thus "rescuing" them from MTX's effects [1]. It is also used in combination with fluorouracil (5-FU) to enhance the efficacy of colorectal cancer treatment [2]. Additionally, it manages megaloblastic anemia due to folate deficiency when oral folic acid is unsuitable [3].
