Natriumlevofolinat Medac (Levoleucovorin Disodium)

Levoleucovorin Disodium, the active ingredient in Natriumlevofolinat Medac, is a folate analog presented as a sterile injectable solution for intravenous use. It is employed to rescue patients from methotrexate toxicity and to enhance the efficacy of fluoropyrimidine chemotherapy in oncology settings.

GNH USA supplies Natriumlevofolinat Medac as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres and pharmacies worldwide.

Levoleucovorin Disodium is used to modulate folate pathways in cancer therapy and to mitigate methotrexate‑induced toxicity.

- Methotrexate toxicity rescue: reduces cellular damage caused by high‑dose methotrexate by supplying reduced folate. - 5‑Fluorouracil chemotherapy enhancement: stabilises the 5‑FU‑TS complex, increasing antitumour activity. - Folate deficiency support: provides active folate to patients with functional deficiency during intensive chemotherapy.

Levoleucovorin Disodium may cause adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea - Mild rash or erythema - Transient hypotension - Headache - Flushing - Mild fatigue

Serious or Rare Side Effects: - Anaphylactic or severe hypersensitivity reactions - Acute renal impairment - Significant hepatic dysfunction - Severe electrolyte disturbances (e.g., hyperkalemia) - Thromboembolic events - Life‑threatening infusion reactions

Before administering Levoleucovorin Disodium, clinicians should consider several safety measures.

- Renal function: evaluate creatinine clearance and adjust if impaired. - Hepatic function: monitor liver enzymes, especially in patients with pre‑existing liver disease. - Pregnancy: use only when the potential benefit justifies the potential risk to the fetus. - Concomitant methotrexate: coordinate timing to ensure effective rescue. - Known hypersensitivity: discontinue immediately if an allergic reaction occurs. - Store at 2‑8°C: keep refrigerated, protect from light, do not freeze or shake the vial.

Levoleucovorin Disodium can interact with several agents; awareness of these interactions helps optimise therapy.

Major Interactions (Avoid): - High‑dose methotrexate administered without appropriate timing may diminish rescue efficacy. - Other antifolates (e.g., pemetrexed) may antagonise its action.

Moderate Interactions (Monitor Closely): - Nephrotoxic drugs such as cisplatin can increase renal burden; monitor renal parameters. - Hepatotoxic agents (e.g., high‑dose acetaminophen) may exacerbate liver injury; observe liver function. - Drugs affecting renal clearance (e.g., NSAIDs) may require dose adjustment or closer monitoring.
