Leflunomide is a drug used to treat adults with rheumatoid arthritis and certain other autoimmune diseases. It works by blocking an enzyme involved in the production of certain substances that can cause inflammation in the body. It can help reduce joint pain, swelling, and stiffness in adults with rheumatoid arthritis. It can also help reduce the number of flare-ups of the disease.
Leflunomide, sold under the brand name Arava among others, is a medication used to treat moderate to severe rheumatoid arthritis and psoriatic arthritis . Here's a breakdown of its key features:
Function: Leflunomide belongs to a class of drugs called disease-modifying antirheumatic drugs (DMARDs). The exact mechanism of action isn't fully understood, but it's believed to work by suppressing the immune system's overactivity, which contributes to inflammation and joint damage in these conditions.
Applications: Leflunomide is primarily used for:
- Moderate to severe rheumatoid arthritis: It helps reduce inflammation, pain, stiffness, and swelling in the joints, ultimately slowing down joint damage and improving physical function.
- Psoriatic arthritis: This is a type of inflammatory arthritis that affects people with psoriasis, a skin condition. Leflunomide helps manage joint pain, swelling, and stiffness associated with psoriatic arthritis.
Benefits:
- Slows disease progression: Leflunomide can help slow down the progression of joint damage in rheumatoid arthritis and psoriatic arthritis.
- Improves symptoms: It can significantly reduce pain, stiffness, and inflammation in affected joints, leading to improved mobility and functionality.
- Relatively well-tolerated: Compared to some other DMARDs, Leflunomide may have a more favorable side effect profile.
Important Considerations:
- Not a cure: Leflunomide doesn't cure rheumatoid arthritis or psoriatic arthritis but helps manage the symptoms and slow down disease progression.
- Slow onset of action: It may take several weeks or even months to experience the full benefits of Leflunomide.
- Potential side effects: These can include nausea, diarrhea, hair loss, rash, and elevated liver enzymes. Regular blood tests are necessary to monitor for potential side effects.
- Pregnancy risks: Leflunomide can cause severe birth defects. Women of childbearing potential must use effective contraception while taking Leflunomide and for a period after stopping the medication to ensure complete elimination from the body.
