Inflectra® (infliximab)

What is Inflectra and what is it used for?

Inflectra’s active substance is called infliximab which is a type of protein of human and mouse origin.

Inflectra belongs to a group of medicines called “TNF blockers” and it is used in adults for the following inflammatory diseases:

  • Rheumatoid arthritis

  • Psoriatic arthritis

  • Ankylosing spondylitis (Bechterew’s disease)

  • Psoriasis

Inflectra is also used in adults and children 6 years of age and older for:

Inflectra works by blocking the action of a protein called “tumour necrosis factor alpha” (TNFα).  This protein is involved in the inflammatory processes of the body and blocking it can reduce inflammation in the body.
