Unifolin 50mg Injection

About

Unifolin 50mg Injection, also known as folinic acid or leucovorin, is a reduced form of folic acid that bypasses the need for reduction by the enzyme dihydrofolate reductase. Its primary clinical utility lies in its role as a "rescue" agent, designed to mitigate the severe toxic effects of folic acid antagonists, most notably methotrexate, on healthy rapidly dividing cells, while preserving the cytotoxic impact on cancer cells. Furthermore, Unifolin is crucial for enhancing the cytotoxic activity of fluorouracil in the treatment of certain colorectal cancers. It achieves this by stabilizing the binding of fluorouracil's active metabolite to thymidylate synthase, thereby prolonging and intensifying its anti-tumor effect. This dual role makes Unifolin indispensable in optimizing chemotherapy regimens and significantly reducing the incidence and severity of severe adverse drug reactions.
