Sodiofolin, also known as sodium folinate or leucovorin calcium, is a medication widely used in the treatment of various medical conditions, particularly in cancer therapy. It acts as a form of folate, a vitamin B that is essential for the synthesis and repair of DNA, and is often used to enhance the effectiveness of certain chemotherapy drugs, such as methotrexate, by protecting healthy cells and reducing side effects. Additionally, Sodiofolin is used to treat or prevent low blood levels of folate (folate deficiency), which can lead to certain types of anemia. It is available in both oral and injectable forms, making it versatile in its application for different patient needs. Its role in supporting cell repair and replication also makes it useful in other medical scenarios, such as in the treatment of methanol and certain other types of poisoning.
