Tremfya (guselkumab) is a prescription medication that treats psoriatic arthritis (psoriasis and pain and stiffness in your joints) and moderate to severe plaque psoriasis (itchy patches on your skin)
Tremfya (guselkumab) blocks interleukin 23 (IL-23), a pro-inflammatory cytokine that is one of the reasons for chronic immune-mediated diseases such as plaque psoriasis and psoriatic arthritis.
Tremfya acts as a fully human monoclonal IgG1λ antibody that binds to the p19 subunit of interleukin (IL)-23 (occurring cytokine involved in normal inflammatory and immune responses) and interaction with the IL-23 receptor.
The blockage stops the release of cytokines and chemokines that cause inflammation.
Plaque psoriasis is a variant of psoriasis. Tremfya is part of biological therapy (medication that affects your whole body) or phototherapy (treatment with light).
It comes in the following forms:
- Single-dose prefilled syringe
- Single-dose one-press patient-controlled injector
