Methotrexate Accord

Methotrexate, the active ingredient in Methotrexate Accord, is an Antimetabolite (Folate antagonist) presented as a sterile injectable for intra‑arterial, intramuscular and intrathecal use. It is employed to treat autoimmune disorders and several malignancies in adult and pediatric patients.

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

Methotrexate acts on rapidly dividing cells and immune pathways, making it useful across several disease families. - Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: limits skin cell proliferation and improves plaque lesions. - Acute lymphoblastic leukemia: interferes with leukemic cell DNA synthesis, aiding remission. - Non‑Hodgkin lymphoma: impedes malignant lymphocyte growth. - Gestational trophoblastic disease: promotes resolution of abnormal trophoblastic tissue.

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

Common Side Effects: - Nausea and vomiting: gastrointestinal upset that may require anti‑emetic support. - Fatigue: persistent tiredness affecting daily activities. - Oral mucositis: painful mouth sores and ulceration. - Mild liver enzyme elevation: transient increase in transaminases.

Serious or Rare Side Effects: - Severe bone marrow suppression: pancytopenia requiring close hematologic monitoring. - Pulmonary toxicity: interstitial pneumonitis that can be life‑threatening. - Hepatotoxicity: significant liver injury or fibrosis with prolonged use. - Renal failure: impaired clearance leading to drug accumulation. - Opportunistic infections: due to immunosuppression. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Methotrexate requires careful monitoring and specific safety measures. - Pregnancy: contraindicated (Category X); avoid use in pregnant patients. - Renal function: assess baseline and monitor; dose adjustment may be needed. - Liver function: regular liver enzyme testing is recommended. - Hematologic monitoring: perform complete blood counts frequently to detect cytopenias. - Drug interactions: avoid concurrent NSAIDs and certain antibiotics without supervision. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

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

Major Interactions (Avoid): - NSAIDs: increase risk of renal toxicity and bone marrow suppression. - Trimethoprim‑sulfamethoxazole: additive myelosuppression. - Live vaccines: heightened infection risk due to immunosuppression. - Pemetrexed: overlapping folate antagonism leading to excess toxicity.

Moderate Interactions (Monitor Closely): - Proton pump inhibitors: may affect gastrointestinal absorption. - Phenytoin: can reduce methotrexate plasma levels. - Azathioprine: additive immunosuppressive effect requiring blood count monitoring.
