Bupleurum Overview

Guselkumab Overview
-
Guselkumab injection is used to treat moderate to severe plaque psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in adults whose psoriasis is too severe to be treated by topical medications alone. It is also used alone or in combination with other medications to treat psoriatic arthritis (a condition that causes joint pain and swelling and scales on the skin) in adults. Guselkumab injection is in a class of medications called monoclonal antibodies. It works by stopping the action of certain cells in the body that cause the symptoms of psoriasis.
