Ixepro is not a hormone drug, its drug generic name should be called recombinant human type II tumor necrosis factor receptor-antibody fusion protein for injection, which has a relatively good anti-inflammatory effect and can be used mainly for the treatment of inflammatory diseases. Studies have shown that tumor necrosis factor is a cytokine and a very important inflammatory mediator in the pathological processes of rheumatoid arthritis, psoriasis and ankylosing spondylitis. Its involvement in regulating the inflammatory response may lead to pathological changes in the joints. The mechanism of action of Ixepro is to be able to compete with the tumor necrosis factor in the blood, thus blocking its binding to the receptor and weakening the effect of tumor necrosis factor, thus acting as an anti-inflammatory agent. In conclusion, this drug can be used clinically for rheumatoid arthritis, psoriasis and ankylosing spondylitis, mainly to play the anti-inflammatory effect, it does not belong to the hormone drugs.
