Enbrel is a medication that is used to treat several autoimmune diseases like rheumatoid arthritis and psoriasis. This medicine contains a substance called etanercept that inhibits the action of tumor necrosis factor (TNF) in the body, thereby reducing inflammation and the symptoms associated with these diseases. There isn't a direct synonym for Enbrel since it's a brand name medication. However, there are other TNF inhibitors that are similar to Etanercept, such as Humira, Remicade, and Cimzia, that can be used as alternatives or used in conjunction with Enbrel to maximize therapeutic benefits. Hence, it is always advisable to consult your doctor to find the most suitable medication to treat your specific condition.
