Arava – Uses, Side Effects, and Dosage for Rheumatoid Arthritis and Psoriatic Arthritis Treatment

Overview of Arava for Rheumatoid Arthritis and Psoriatic Arthritis

Arava is a prescription medication that is primarily used to treat rheumatoid arthritis and psoriatic arthritis. It belongs to a class of drugs known as disease-modifying antirheumatic drugs (DMARDs), which work by suppressing the immune system and reducing inflammation in the joints.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation in the joints. It can lead to pain, stiffness, and swelling, and if left untreated, it can cause joint damage and disability. Arava is often prescribed as part of a comprehensive treatment plan for rheumatoid arthritis, which may include other medications, physical therapy, and lifestyle changes.

According to the Arthritis Foundation, approximately 1.5 million people in the United States are affected by rheumatoid arthritis. It is more common in women than in men, and it typically develops between the ages of 30 and 60.

Psoriatic Arthritis

Psoriatic arthritis is a type of inflammatory arthritis that occurs in some people with psoriasis, a chronic skin condition. It can cause joint pain, stiffness, and swelling, as well as skin symptoms such as red patches of skin with silvery scales. Arava is often prescribed to help manage the symptoms of psoriatic arthritis and slow down the progression of joint damage.

According to a study published in the journal JAMA Dermatology, approximately 30% of people with psoriasis develop psoriatic arthritis. It can affect both men and women, typically between the ages of 30 and 50.

How Arava Works

Arava works by inhibiting the production of certain immune cells that are involved in the inflammation process. It specifically targets the enzyme dihydroorotate dehydrogenase (DHODH), which is necessary for the proliferation of these immune cells.

This mechanism of action helps to reduce the inflammation in the joints, alleviate pain, and slow down the progression of joint damage. By suppressing the immune system, Arava helps to prevent further destruction of the cartilage and bone in the affected joints.

It is important to note that Arava is not a cure for rheumatoid arthritis or psoriatic arthritis, but it can help manage the symptoms and improve quality of life for those living with these conditions.

In the next section, we will discuss the potential side effects and precautions associated with Arava.

3. How Does Arava Work?

Arava, a disease-modifying antirheumatic drug (DMARD), works by suppressing the immune system and reducing inflammation in the body. This helps to alleviate the symptoms of rheumatoid arthritis and psoriatic arthritis, the two conditions it is primarily prescribed for.
When a person has rheumatoid arthritis or psoriatic arthritis, their immune system is overactive and attacks the joints, leading to pain, swelling, and stiffness. Arava contains the active ingredient leflunomide, which inhibits the activity of certain immune cells called T lymphocytes.
By targeting these immune cells, Arava helps to reduce the inflammatory response in the joints that causes the characteristic symptoms of arthritis. This helps to improve joint function and reduce the pain and swelling associated with these conditions.
How Does Arava Compare to Other Medications?
Arava is part of a class of drugs known as DMARDs, which also includes other commonly prescribed medications for arthritis such as methotrexate and sulfasalazine. While these medications work in a similar way by suppressing the immune system, they may have slightly different mechanisms of action and side effect profiles.
According to a study published in the journal “Arthritis Research & Therapy,” Arava was found to be as effective as methotrexate in treating rheumatoid arthritis symptoms. The study also compared the safety profiles of the two medications and found that both had similar rates of adverse events, although methotrexate was associated with a higher rate of liver toxicity.
In another study published in the “British Journal of Dermatology,” Arava was found to be effective in reducing the symptoms of psoriasis, a condition that often accompanies psoriatic arthritis. The study compared the efficacy of Arava with another commonly prescribed medication for psoriatic arthritis, methotrexate, and found that both drugs significantly improved skin symptoms.
Side Effects and Precautions
Like all medications, Arava can cause side effects. The most common side effects include diarrhea, nausea, skin rash, and hair loss. These side effects are usually mild and go away on their own. However, if they persist or become bothersome, it is important to inform your doctor.
It is important to note that Arava can also affect the liver, so regular liver function tests are recommended while taking this medication. In rare cases, Arava can cause serious liver damage, so it is important to promptly report any symptoms such as abdominal pain or jaundice to your doctor.
Arava is also not recommended for use in pregnant women, as it can cause harm to the developing fetus. Women of childbearing age who are taking Arava should use effective contraception to avoid pregnancy.
Conclusion
Arava is a prescription medication that effectively treats rheumatoid arthritis and psoriatic arthritis by suppressing the immune system and reducing inflammation. It belongs to a class of drugs called DMARDs and is comparable in efficacy and safety to other commonly prescribed arthritis medications. However, like all medications, it can cause side effects and requires regular monitoring to ensure its safe and effective use. If you are considering taking Arava, it is important to discuss the potential risks and benefits with your doctor.
