Metotressato Teva

Methotrexate, the active ingredient in Metotressato Teva, is a folate antagonist presented as a sterile solution for epidural, intrabursal, and intracoronary use. It is employed to treat autoimmune disorders and certain cancers in adult patients. The drug interferes with DNA synthesis, providing immunosuppressive and antineoplastic effects. It is indicated for conditions such as rheumatoid arthritis, psoriasis, acute lymphoblastic leukemia, and osteosarcoma.

GNH USA supplies Metotressato Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres, and pharmacies worldwide. The company ensures quality assurance, regulatory compliance, and reliable cold‑chain logistics for all shipments.

Methotrexate is used in several disease categories where inhibition of folate metabolism is therapeutic. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: decreases skin cell proliferation, improving plaque severity. - Acute lymphoblastic leukemia: interferes with malignant cell replication, supporting remission. - Osteosarcoma: provides antineoplastic activity as part of multimodal therapy.

Methotrexate may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea or vomiting - Fatigue - Mild elevation of liver enzymes

Serious or Rare Side Effects: - Severe liver toxicity or fibrosis - Pulmonary fibrosis or interstitial pneumonitis - Bone marrow suppression leading to pancytopenia

Methotrexate requires careful monitoring and specific safety measures. - Pregnancy: contraindicated; category X due to teratogenic risk. - Renal function: assess before initiation and monitor regularly. - Hepatic function: avoid in patients with active liver disease; monitor enzymes. - Immunosuppression: monitor for infections; advise patients to report fever. - Concomitant NSAIDs: increase risk of renal toxicity; use with caution. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Methotrexate interacts with several medicines that may alter its safety or efficacy.

Major Interactions (Avoid): - Live vaccines: may cause severe infection. - High-dose aspirin or NSAIDs: increase risk of renal toxicity. - Trimethoprim‑sulfamethoxazole: can enhance myelosuppression.

Moderate Interactions (Monitor Closely): - Proton pump inhibitors: may affect absorption. - Azathioprine or other immunosuppressants: additive bone marrow suppression. - Phenytoin: may reduce methotrexate levels.
