Metother

Methotrexate, the active ingredient in Metother, is an antimetabolite presented as a subcutaneous formulation for subcutaneous use. It treats autoimmune conditions such as rheumatoid arthritis and psoriasis, and is also employed in certain cancers and ectopic pregnancy.

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

Methotrexate is employed in several immune‑mediated and oncologic conditions where inhibition of cell proliferation is desired. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: improves skin lesions and decreases plaque formation. - Acute lymphoblastic leukemia: interferes with malignant cell replication leading to remission. - Non‑Hodgkin lymphoma: contributes to tumor control by inhibiting DNA synthesis. - Ectopic pregnancy: terminates trophoblastic tissue non‑surgically.

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

Common Side Effects: - Nausea and vomiting: mild to moderate gastrointestinal upset. - Fatigue: persistent tiredness. - Mouth ulcers: painful sores in the oral cavity. - Elevated liver enzymes: mild hepatic irritation.

Serious or Rare Side Effects: - Severe liver toxicity: risk of hepatitis or fibrosis. - Pulmonary toxicity: interstitial pneumonitis or fibrosis. - Bone marrow suppression: pancytopenia leading to infection or bleeding. - Renal impairment: reduced kidney function or acute failure.

When using Metother, several safety considerations are essential. - Pregnancy: contraindicated due to teratogenic risk (Category X). - Renal function: assess creatinine clearance before initiation. - Liver function: monitor transaminases regularly. - Blood counts: perform complete blood count before each dose. - Concurrent NSAIDs: avoid or use with caution due to renal risk. - Store at ambient temperature: keep in the original pack, protect from moisture and light.

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

Major Interactions (Avoid): - Live vaccines: may cause severe infection. - High‑dose aspirin: increases risk of bone marrow suppression. - Trimethoprim‑sulfamethoxazole: potentiates myelosuppression.

Moderate Interactions (Monitor Closely): - Non‑steroidal anti‑inflammatory drugs (NSAIDs): may affect renal clearance. - Proton pump inhibitors: may alter methotrexate elimination.
