Methotrexate Accord

Methotrexate, the active ingredient in Methotrexate Accord, is an antimetabolite presented as a sterile solution for intra‑arterial, intramuscular, and intravenous use. It treats rheumatoid arthritis, psoriasis, acute lymphoblastic leukemia, osteosarcoma, and gestational trophoblastic disease in the appropriate patient populations.

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

Methotrexate is an antimetabolite used in several autoimmune and oncologic disease families.

- Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: improves skin lesions and decreases plaque formation. - Acute lymphoblastic leukemia: induces remission by inhibiting malignant cell proliferation. - Osteosarcoma: incorporated into chemotherapy regimens to limit tumor growth. - Gestational trophoblastic disease: helps eradicate trophoblastic tissue.

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

Common Side Effects: - Nausea - Oral mucositis - Fatigue - Alopecia

Serious or Rare Side Effects: - Bone marrow suppression - Severe hepatic toxicity - Pulmonary fibrosis - Life‑threatening infections

Methotrexate requires careful monitoring and specific safety measures.

- Pregnancy: contraindicated (Category X) – avoid use in pregnant women. - Renal function: assess before initiating; dose adjustment may be needed in impairment. - Hepatic function: monitor liver enzymes regularly during therapy. - NSAID co‑administration: increases risk of toxicity – monitor closely. - Concomitant antibiotics (e.g., penicillins): may reduce clearance and raise serum levels. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Methotrexate interacts with several drug classes that can alter its safety profile.

Major Interactions (Avoid): - NSAIDs: increase methotrexate toxicity. - Penicillins (e.g., ampicillin): reduce renal clearance, raising serum levels. - Proton pump inhibitors (e.g., omeprazole): may enhance toxicity.

Moderate Interactions (Monitor Closely): - Sulfonamides: may increase risk of bone marrow suppression. - Live vaccines: immunosuppression may reduce efficacy and raise infection risk.
