Metotressato Teva

Methotrexate, the active ingredient in Metotressato Teva, is an antimetabolite (folate antagonist) presented as a sterile injectable solution for epidural, intra‑articular and intramuscular use. It is employed to manage rheumatoid arthritis, psoriasis, certain malignancies and selected intra‑articular inflammatory joint conditions in adult patients. GNH USA supplies Metotressato Teva 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: diminishes skin plaque formation and severity. - Certain malignancies (e.g., leukemia, lymphoma): interferes with cancer cell proliferation. - Intra‑articular treatment of osteoarthritis or inflammatory joint disease: provides local immunosuppression and pain relief.

Methotrexate may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects: - Nausea and vomiting: gastrointestinal discomfort that may be transient. - Fatigue: persistent tiredness affecting daily activities. - Elevated liver enzymes: mild hepatic changes detectable on laboratory testing.

Serious or Rare Side Effects: - Severe liver toxicity: risk of hepatitis or fibrosis requiring monitoring. - Pulmonary fibrosis: progressive scarring of lung tissue. - Bone marrow suppression: severe anemia, leukopenia or thrombocytopenia that can lead to infection or bleeding.

Before initiating therapy, clinicians should assess several safety parameters. - Monitor liver function: perform baseline and periodic liver enzyme tests. - Monitor blood counts: regular complete blood counts to detect marrow suppression. - Avoid use in pregnancy: methotrexate is contraindicated and requires effective contraception. - Adjust for renal impairment: dose modifications may be needed in reduced kidney function. - Store at ambient temperature: keep in the original container, protect from moisture and light.

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

Major Interactions (Avoid): - NSAIDs: increase risk of renal toxicity and gastrointestinal ulceration. - Trimethoprim‑sulfamethoxazole: additive bone‑marrow suppression. - Live vaccines: heightened infection risk due to immunosuppression.

Moderate Interactions (Monitor Closely): - Proton pump inhibitors: may affect methotrexate absorption and clearance. - Azathioprine: combined immunosuppression can raise infection susceptibility.
