by ADMIN 43 views

Leucovorin is a medication primarily used to reduce the toxicity and counteract the effects of methotrexate, a drug used in the treatment of cancer and certain autoimmune diseases. It is also used in combination with 5-fluorouracil to treat colorectal cancer. Leucovorin is a folic acid analog, meaning it is similar in structure to folic acid, a type of B vitamin. — Vikings Injury Report: Key Players And Latest Updates

How Leucovorin Works

Leucovorin works by providing the body with a form of folic acid that can be readily used by cells. This helps to protect normal cells from the harmful effects of methotrexate, which can inhibit the body's ability to use folic acid. In the treatment of colorectal cancer, leucovorin enhances the effectiveness of 5-fluorouracil by helping it bind more tightly to its target enzyme.

Uses of Leucovorin

  • Methotrexate Rescue: Leucovorin is commonly used after high-dose methotrexate therapy to prevent or reduce the severity of side effects such as:
    • Mucositis: Inflammation and ulceration of the mucous membranes.
    • Bone Marrow Suppression: Reduction in the production of blood cells.
    • Kidney Damage: Impairment of kidney function.
  • Colorectal Cancer Treatment: Leucovorin is often used in combination with 5-fluorouracil (5-FU) to treat colorectal cancer. It helps to increase the effectiveness of 5-FU in killing cancer cells.
  • Folic Acid Deficiency: In some cases, leucovorin may be prescribed to treat folic acid deficiency, particularly when the deficiency is caused by certain medications or medical conditions.

Dosage and Administration

The dosage of leucovorin varies depending on the specific condition being treated and the individual patient's needs. It is typically administered intravenously (IV) or orally. When used for methotrexate rescue, the dosage and duration of leucovorin treatment are determined by the methotrexate levels in the patient's blood. It is crucial to follow the doctor's instructions carefully when taking leucovorin. — Explore The Variety Of Bark: A NYT Guide
