🔬 1. Product Overview: Leucolieva 300 mg Injection

Leucolieva 300 mg Injection contains Leucovorin Calcium (also known as Folinic Acid), a critical biochemical modulator used to enhance the efficacy of chemotherapy and protect healthy cells from high-dose toxicity.

• Composition: Leucovorin Calcium IP/USP 300 mg (per vial)

• Therapeutic Class: Cytoprotective Agent / Folic Acid Derivative

• Formulation Type: Sterile lyophilized powder for reconstitution or concentrate for IV infusion

• Key Advantage: The 300 mg dosage is optimized for high-dose "rescue" protocols and synergistic chemotherapy combinations.

⚙️ 2. Mechanism of Action

Leucolieva functions as a metabolically active form of folate that does not require the enzyme dihydrofolate reductase to be effective:

• Methotrexate Rescue: In high-dose methotrexate therapy, Leucovorin bypasses the enzyme block in healthy cells, providing a source of folate to restart DNA synthesis and prevent lethal systemic toxicity.

• 5-Fluorouracil (5-FU) Potentiation: In colorectal cancer treatment, Leucovorin binds to thymidylate synthase alongside 5-FU, creating a stronger inhibitory complex. This "locks" the enzyme, significantly increasing the tumor-killing power of the chemotherapy.

• Anemia Management: It acts as a direct source of folic acid for patients with megaloblastic anemia when oral absorption is compromised.

🏥 3. Therapeutic Indications

Leucolieva 300 mg Injection is clinically indicated for:

• Oncology Rescue: Reducing toxicity and counteracting the effects of impaired methotrexate elimination.

• Colorectal Cancer: Used as part of the FOLFOX or FOLFIRI regimens for advanced metastatic colon and rectal cancer.

• Overdose Antidote: Treating accidental overdoses of folic acid antagonists (e.g., pyrimethamine or trimethoprim).

• Megaloblastic Anemia: For patients with severe folic acid deficiency where IV therapy is mandatory.

⚠️ 4. Administration & Safety Guidelines

• Route: Must be administered only by Intravenous (IV) or Intramuscular (IM) injection.

• Fatal Warning: NEVER administer Leucovorin intrathecally. Intrathecal administration of this medication is fatal.

• Monitoring: Continuous monitoring of serum methotrexate levels and creatinine levels is required during rescue therapy.

• Side Effects: Generally well-tolerated, though potential reactions include nausea, vomiting, or rare hypersensitivity reactions (hives, rapid heartbeat).
