In the treatment of psoriatic arthritis, the following options are available: 1. Non-steroidal anti-inflammatory drugs: such as ibuprofen extended-release tablets, which can play a role in anti-inflammatory and analgesic treatment. 2. Immunomodulatory drugs: such as cyclosporine soft capsules, which can play a role in suppressing local inflammatory factors, or you can choose tretinoin multi-glucoside tablets, which play a role in anti-inflammatory, analgesic, and immunomodulatory treatment, both of which need to be reviewed for blood tests, liver and kidney function when applied. The two drugs need to be reviewed for blood tests, liver and kidney function, and tretinoin can also cause reproductive effects, so men and women of childbearing age should apply this drug with caution. 3, biological agents: you can choose ustekinumab or secukinumab treatment.
