BIOVORIN 50MG INJECTION

About

Biovorin 50mg Injection contains Leucovorin, a form of folinic acid, which is a reduced derivative of folic acid. Unlike folic acid, leucovorin does not require reduction by dihydrofolate reductase to be metabolically active. It serves as a biochemical rescue agent in high-dose methotrexate therapy, protecting healthy cells from the toxic effects of methotrexate by providing a readily available source of reduced folates. Methotrexate inhibits dihydrofolate reductase, depleting intracellular folate cofactors essential for DNA synthesis and repair.

Leucovorin bypasses this enzymatic block, allowing normal cells to synthesize purines and pyrimidines, thereby mitigating methotrexate-induced myelosuppression and mucositis. Additionally, leucovorin is used in combination with fluorouracil to enhance its cytotoxic activity against certain cancers, particularly colorectal cancer. It stabilizes the binding of fluorouracil's active metabolite to thymidylate synthase, leading to prolonged inhibition of DNA synthesis and increased cell death in cancer cells. Its role is crucial in both protecting healthy tissues and enhancing chemotherapy efficacy.

Uses

• Methotrexate Rescue Therapy
• Colorectal Cancer (with Fluorouracil)
• Megaloblastic Anemia (due to folate deficiency)
• Antidote for Folic Acid Antagonists

Directions For Use

Administered intravenously or intramuscularly by a healthcare professional. Dosage and schedule depend on the specific indication and concurrent chemotherapy regimen.

Benefits

• Reduces methotrexate toxicity
• Enhances fluorouracil efficacy
• Protects healthy cells during chemotherapy
• Supports DNA synthesis in normal cells
• Treats certain megaloblastic anemias
• Essential in specific cancer protocols

Side Effects

• Allergic reactions (rare)
• Fever
• Nausea
• Vomiting
• Diarrhea
• Stomatitis (when used with fluorouracil)
• Rash
• Pruritus
• Insomnia
• Agitation
• Seizures (rare)
• Thrombophlebitis at injection site

Safety Measures

• Alcohol - No specific interaction with alcohol is known, but general health considerations during chemotherapy apply.
• Pregnancy - Use during pregnancy only if clearly needed and the potential benefits outweigh the risks. Consult a physician.
• Breastfeeding - It is unknown if leucovorin is excreted in human milk. Caution should be exercised, and breastfeeding may be discontinued during treatment.
• Liver - No specific dose adjustment is typically required for liver conditions, but overall patient status should be considered during chemotherapy.
• Kidney - Use with caution in patients with renal impairment, especially during high-dose methotrexate therapy, as impaired methotrexate excretion can increase toxicity.
• Lung - No specific precautions are generally needed for patients with lung conditions, as leucovorin does not typically cause pulmonary toxicity.
