Which drug is used to treat Multiple Sclerosis?

Copaxone, also known by its generic name glatiramer acetate, is specifically indicated for the treatment of relapsing forms of multiple sclerosis (MS). It works by modulating the immune response, helping to reduce the frequency of relapses and delaying the progression of disability in patients with MS. This mechanism is particularly beneficial for managing the autoimmune processes involved in this condition.

Other medications listed do not target multiple sclerosis. Enbrel, for example, is primarily used for autoimmune conditions like rheumatoid arthritis and psoriasis. Xtandi and Zytiga are drugs used primarily for the treatment of prostate cancer, with no indication for multiple sclerosis. Thus, Copaxone stands out as the appropriate choice for managing MS due to its specific clinical use and action relevant to the disease.
