Introduction

Tofacit XR is an inhibitor of the Janus kinase (JAK) family of enzymes. It is used to treat rheumatoid arthritis (RA) and psoriatic arthritis. It works by inhibiting the activation of signal transduction proteins involved in the overproduction of pro-inflammatory proteins. It is classified as a "biologic" medication, meaning that it is made up of genetically engineered proteins.

Uses

Tofacit XR is used to treat adults with active rheumatoid arthritis (RA). It can also be used to treat psoriatic arthritis in adults. Tofacit XR can reduce the signs and symptoms of RA and help improve physical function.

Mechanism of Action

Tofacit XR works by inhibiting the Janus kinase (JAK) family of enzymes. JAKs are involved in the activation of signal transduction proteins involved in the overproduction of pro-inflammatory proteins. By inhibiting the action of the JAKs, tofacitinib decreases the production of these pro-inflammatory proteins, relieving the symptoms of RA and psoriatic arthritis.
