Tofacitinib 5 mg tablets are prescribed to treat certain types of inflammatory conditions. These include active psoriatic arthritis, moderate to severe active rheumatoid arthritis, and ulcerative colitis [1].
What is Tofacitinib Used For?
Tofacitinib is a Janus kinase (JAK) inhibitor. It works by blocking the action of certain enzymes that are involved in the inflammatory processes of autoimmune diseases [1]. For psoriatic arthritis and rheumatoid arthritis, it helps reduce joint swelling, pain, and stiffness, thereby improving physical function [1]. In ulcerative colitis, it helps to reduce inflammation in the colon, leading to fewer bowel movements and less bleeding [1].
How Long Does Tofacitinib Treatment Last?
The duration of tofacitinib treatment is determined by a healthcare professional based on the patient's response and the severity of the condition [1]. It is typically used when other treatments have not been effective or when a different approach is needed [1].
What Are the Risks Associated with Tofacitinib?
Tofacitinib carries certain risks, including an increased risk of serious infections, blood clots, heart attack, stroke, and certain cancers [1]. Patients should discuss their full medical history, including any existing conditions and other medications they are taking, with their doctor before starting treatment [1]. Regular monitoring is often required during treatment [1].
How Does Tofacitinib Work?
Tofacitinib targets JAK enzymes, specifically JAK1 and JAK3, and to a lesser extent JAK2. These enzymes play a role in signaling pathways that promote inflammation. By inhibiting these pathways, tofacitinib can dampen the immune response that drives autoimmune diseases [1].
What is the Patent Status of Tofacitinib?
Information on the patent status of tofacitinib, including expiry dates and any ongoing patent litigation, can be found on specialized drug patent databases [2]. These resources track intellectual property related to pharmaceutical products.
Who Manufactures Tofacitinib?
Tofacitinib is manufactured by Pfizer Inc. [1].
