Leucovorin Calcium 5mg Tablets In Pakistan

Leucovorin Calcium 5 mg Tablets contain leucovorin calcium, a reduced form of folic acid (folinic acid) that works as a rescue agent in certain chemotherapy regimens and to support folate levels in the body. Unlike regular folic acid, leucovorin doesn’t require conversion by the dihydrofolate reductase enzyme, allowing it to directly participate in essential cellular processes such as DNA synthesis and repair. These tablets are used under medical supervision to lessen the harmful effects of some cancer treatments and to manage specific folate-related conditions.

Key Benefits:

Reduces methotrexate toxicity: Helps protect healthy cells from the toxic effects of methotrexate, a chemotherapy drug, by supplying reduced folates needed for normal cell function.
Enhances certain chemotherapy effects: When used with 5-fluorouracil (5-FU), leucovorin can improve the effectiveness of cancer treatment by stabilizing drug-enzyme interactions.
Supports folate status: Helps manage folate deficiency (e.g., megaloblastic anemia) when other forms of folic acid aren’t suitable.
Improves DNA and RNA synthesis: Provides active folate cofactors necessary for nucleotide production and cellular repair processes.

How It Works:

Leucovorin calcium works by bypassing the metabolic block caused by folic acid antagonists such as methotrexate. Methotrexate inhibits an enzyme (dihydrofolate reductase) required to convert folic acid into its active form. Since leucovorin is already in a reduced, active form, it supplies the body with functional folate, allowing healthy cells to continue DNA synthesis and repair. This reduces damage to normal tissues during chemotherapy. Additionally, when used with 5-fluorouracil, leucovorin enhances the drug’s anticancer activity by stabilizing complexes that interfere with cancer cell DNA synthesis.

How to Use:

Take as prescribed: Follow your doctor’s exact instructions — dosage and timing depend on your specific medical condition and treatment plan.
Oral administration: Swallow the tablet whole with a full glass of water; it can usually be taken with or without food.
Medical supervision: Because doses are tailored and may vary widely depending on use (chemotherapy rescue, folate deficiency, etc.), do not self-administer without a healthcare provider’s guidance.
