Methotrexat Sandoz

Methotrexate, the active ingredient in Methotrexat Sandoz, is a antimetabolite presented as a formulation for intra‑arterial, intramuscular and intrathecal use. It is employed to treat rheumatoid arthritis, psoriasis, certain leukemias, osteosarcoma and ectopic pregnancy in appropriate patients.

Methotrexate is an antimetabolite used across autoimmune and oncologic disease families.

- Rheumatoid arthritis: reduces joint inflammation and slows disease progression. - Psoriasis: improves skin lesions and decreases severity. - Acute lymphoblastic leukemia: induces remission by inhibiting malignant cell proliferation. - Osteosarcoma: contributes to tumor control as part of combination chemotherapy. - Ectopic pregnancy: facilitates resolution of trophoblastic tissue.

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

Common Side Effects: - Nausea or vomiting. - Oral ulcers or mucositis. - Elevated liver enzymes.

Serious or Rare Side Effects: - Severe bone marrow aplasia causing pancytopenia. - Hepatotoxicity leading to fibrosis or cirrhosis. - Pulmonary toxicity such as interstitial pneumonitis.

When prescribing methotrexate, several precautions should be observed to minimize risk.

- Renal function: assess baseline creatinine and adjust dose in impairment. - Hepatic monitoring: perform liver function tests before and during therapy. - Hematologic surveillance: obtain complete blood count regularly. - Concomitant NSAIDs: avoid or use with caution due to increased toxicity. - Pregnancy and lactation: contraindicated in pregnancy (Category X) and not recommended while breastfeeding. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Methotrexate has notable drug interactions that may require dose adjustment or avoidance.

Major Interactions (Avoid): - Non‑steroidal anti‑inflammatory drugs (NSAIDs): increase methotrexate toxicity. - Live vaccines: risk of severe infection due to immunosuppression. - High‑dose penicillins: may reduce renal clearance of methotrexate.

Moderate Interactions (Monitor Closely): - Sulfonamide antibiotics: additive bone marrow suppression. - Proton pump inhibitors: may increase methotrexate plasma levels.
