Which of the following drugs is used to treat Plaque Psoriasis?

Enbrel is a biologic medication that plays a significant role in the treatment of plaque psoriasis, which is a chronic autoimmune skin condition characterized by the formation of red, scaly patches. Enbrel works by inhibiting the pro-inflammatory protein tumor necrosis factor-alpha (TNF-alpha), which is implicated in inflammatory processes related to psoriasis. By reducing levels of this protein, Enbrel helps to alleviate the symptoms of plaque psoriasis, improving skin appearance and reducing inflammation.

The other medications listed have different indications. Copaxone is primarily used for the treatment of multiple sclerosis, Sovaldi is an antiviral used for hepatitis C treatment, and Xtandi is an antiandrogen used in prostate cancer therapy. These drugs do not have a role in managing plaque psoriasis, making Enbrel the appropriate choice for this condition.
