Rheumatoid arthritis (RA) is a long-term autoimmune disease that causes pain, stiffness, and swelling in different types of joints throughout the body, impacting millions of people in the world and often breaking up their daily activities. Even after taking conventional treatments, like NSAIDs and DMARDs, some people do not achieve adequate relief. In such cases, infusion therapy can be a significant option for RA patients. This treatment involves administering medication directly into the patient’s bloodstream through an IV, targeting specific parts of the immune system to help reduce inflammation. After receiving this therapy, patients reported less pain and improved their joint function. However, it is essential to consult your Doctor before starting this treatment.
Understanding Infusion Therapy
Infusion therapy is a treatment method in that medication is directly administered into the bloodstream through an IV. This approach allows the medication to work more quickly and effectively in the body than oral medicine. IV infusion is particularly beneficial for rheumatoid arthritis patients, especially those suffering from moderate to severe stages. Additionally, it is helpful for those who cannot tolerate the side effects of oral medications. For patients who do not achieve appropriate results from traditional treatments, infusion therapy can be a viable option.
Benefits of Infusion Therapy
- Rapid Action: Infusions can provide faster relief than oral medications, within few hours or days.
- Higher Drug Concentration: Since it is administered directly into the bloodstream, and more effective dosages can be provided.
- Targeted Treatment: Infusion therapy can provide more advanced treatment by targeting specific pathways involved in rheumatoid arthritis.
- Convenience: Infusions are usually treated in a clinical setting.
How Infusion Therapy Works
Infusion therapy for rheumatoid arthritis mainly uses medications made from living organisms that target inflammation in the body. These treatments focus on specific parts of the immune system, it is helped to reduce swelling, relieve pain, and protect the joints from damage.
Types of Infusions for Rheumatoid Arthritis
There are several types of infusion therapies for rheumatoid arthritis, and each one works in its way and has different treatment plans:
1. Infliximab (Remicade)
- Mechanism: Infliximab is a medicine that stops the action of a protein called TNF, which causes inflammation in the body.
- Administration: You start with three infusions at weeks 0, 2, and 6, and then continue with one infusion every 8 weeks.
- Benefits: It is effective in reducing rheumatoid arthritis symptoms, helping with physical abilities, and slowing down the progress of the disease.
- Potential Side Effects: There is a risk of infections, reactions during the infusion (like fever and chills), and the possibility of the body making antibodies against the medicine.
2. Rituximab (Rituxan)
- Mechanism: Rituximab is a type of medicine that targets B cells with a protein called CD20, which is involved in the inflammation process of rheumatoid arthritis.
- Administration: You get two infusions two weeks apart, and then you usually have maintenance infusions every 6 months.
- Benefits: It can greatly improve symptoms in patients who don’t respond to other treatments and is considered safe to use.
- Potential Side Effects: Possible side effects include infusion reactions like headaches and fever, a higher chance of infections, and the risk of serious allergic reactions.
3. Tocilizumab (Actemra)
- Mechanism: Tocilizumab is a medicine that blocks IL-6, a protein involved in inflammation, helping to reduce swelling in rheumatoid arthritis.
- Administration: It is given as an IV infusion every 4 weeks.
- Benefits: It is effective in reducing symptoms of rheumatoid arthritis, and it also improves quality of life while preventing joint damage.
- Potential Side Effects: Possible side effects include elevated liver enzymes, a higher risk of infections, and gastrointestinal perforations.
4. Abatacept (Orencia)
- Mechanism: Abatacept stops T-cell activation, which is an important part of the immune response that causes joint inflammation.
- Administration: It is given as an initial infusion, followed by doses at 2 weeks and 4 weeks, and then every 4 weeks after that.
- Benefits: It can be used with other DMARDs and has a lower risk of serious infections compared to other biological medications.
- Potential Side Effects: Headaches, infections, and reactions related to the infusion.
5. Golimumab (Simponi Aria)
- Mechanism: It is another TNF-alpha inhibitor that reduces inflammation by stopping the action of TNF.
- Administration: It is given as an infusion at the start and then every 8 weeks.
- Benefits: It offers significant relief from symptoms and improves physical function, with an easy dosing schedule.
- Potential Side Effects: Like other TNF inhibitors, it carries risks of infections and infusion reactions.
6. Certolizumab Pegol (Cimzia)
- Mechanism: It is a pegylated Fab’ fragment of a humanized anti-TNF antibody that attaches to TNF and stops it from activating its receptor.
- Administration: It is administered as a subcutaneous injection at weeks 0, 2, and 4, after which it is given every 4 weeks to maintain its therapeutic effects.
- Benefits: It helps reduce the signs and symptoms of rheumatoid arthritis while also improving physical function.
- Potential Side Effects: Possible side effects include injection site reactions, headaches, and a higher risk of infections.
7. Sarilumab (Kevzara)
- Mechanism: This is another IL-6 receptor antagonist that helps lower inflammation in patients with rheumatoid arthritis.
- Administration: It is administered as an injection under the skin once every two weeks.
- Benefits: It helps reduce symptoms and improve physical function, especially for patients who haven’t improved with other treatments.
- Potential Side Effects: There is a risk of infections, increased liver enzymes, and reactions at the injection site.
Tofacent and Baricinix: Innovations in RA Infusion Therapy
Newer medicines like Tofacitinib 5 mg and Baricitinib 4 mg are new choices for treating rheumatoid arthritis. These medicines, which belong to a class known as Janus kinase (JAK) inhibitors, are employed to treat various inflammatory conditions due to their ability to modulate the immune response. They work by targeting the JAK-STAT signaling pathway, which is important for the immune response and inflammation.
Tofacent 5 mg
Tofacent (tofacitinib) is a JAK inhibitor that has been very effective in reducing symptoms of rheumatoid arthritis and improving physical function. It operates through the inhibition of Janus kinase enzymes, which are crucially implicated in the inflammatory processes associated with rheumatoid arthritis. Tofacent can be taken by mouth or given as an infusion, and the infusion option can provide faster relief for severe symptoms.

Baricinix 4 mg
Baricinix (baricitinib) is another JAK inhibitor that targets the JAK1 and JAK2 enzymes. Clinical studies have shown that it effectively reduces joint pain, swelling, and overall disease activity in patients with rheumatoid arthritis. Baricinix is especially helpful for patients who do not get enough relief from TNF inhibitors. Like Tofacent, Baricinix can be taken by mouth or given as an infusion, making it a flexible choice for managing rheumatoid arthritis.
