What Is A Generic?×
A generic drug is essentially a copycat version of a brand-name medication, offering the same safety, quality, and effectiveness, but often at a lower cost. When a brand-name drug's patent expires, other companies can produce the generic version. These generics contain the same active ingredients and work in the same way in the body as the original brand-name drug. However, they might differ in color, shape, or inactive ingredients. The appeal of generic drugs lies in their affordability; they provide a more cost-effective option for consumers without sacrificing the benefits of the original medication. This makes healthcare more accessible to a larger portion of the population, ensuring that more people can receive the treatment they need without the burden of high costs associated with brand-name drugs.
Methotrexate is a medication that is primarily used to treat various forms of cancer. It’s commonly used to treat neck, head, breast, blood, lungs, lymph nodes, bone, and uterus cancers. It may also treat severe psoriasis, rheumatoid arthritis, multiple sclerosis, lupus, polyarticular juvenile idiopathic arthritis, or PJIA. When it’s used to treat PJIA, it’s generally because the child has tried other types of treatments that didn’t work very well.
This medication may be used orally with other medicines to treat relapsed or refractory non-Hodgkins’s lymphoma and acute lymphoblastic leukemia. It can also be used alone or with other medicines to treat mycosis fungi.
This medication is a part of a group of drugs classified as antineoplastics, which are cancer medications. Methotrexate blocks a specific enzyme that cells need to live. This keeps cancer cells from growing or slows that growth, and the body eventually destroys these cells. When used to treat severe psoriasis, it slows down skin cell growth so that the scales present in this condition are kept from growing. It works to treat rheumatoid arthritis by causing less activity in the body’s immune system so that the body doesn’t attack its joints. It’s a prescription medication only.
