How it works

From the US prescribing label for the same active substance (TREMFYA). It describes the substance, not this exact product.

Guselkumab is a human monoclonal IgG1λ antibody that selectively binds to the p19 subunit of interleukin 23 (IL-23) and inhibits its interaction with the IL-23 receptor.

IL-23 is a naturally occurring cytokine that is involved in normal inflammatory and immune responses.

The shape is a standard model drawn from the two times above, not a measurement. How fast a medicine acts and wears off also depends on the dose, the form and the person.
How the body breaks it down

The exact pathway through which guselkumab is metabolized has not been characterized.
