Arava (Leflunomide) – Uses, Dosage, Side Effects, and More

General description of Arava

Arava, also known as leflunomide, is a vital prescription medication used primarily in the treatment of rheumatoid arthritis. This medication falls under the class of disease-modifying antirheumatic drugs (DMARDs), which are crucial in managing the symptoms and progression of rheumatoid arthritis.

• Usage: Arava is prescribed by healthcare professionals to patients with rheumatoid arthritis to help reduce inflammation in the joints, alleviate pain, and improve overall joint function.
• Mechanism of Action: The active ingredient in Arava, leflunomide, works by inhibiting the enzyme dihydroorotate dehydrogenase, ultimately leading to reduced production of pyrimidines in lymphocytes, which are a key factor in the inflammatory response seen in rheumatoid arthritis.
• Administration: Arava is typically taken orally in the form of a tablet, with the recommended dosage varying depending on the severity of the condition and individual response to the medication.

According to a study published in the National Institutes of Health, Arava has shown significant efficacy in reducing disease activity and slowing the progression of joint damage in patients with rheumatoid arthritis. The study highlighted that patients on Arava experienced improved quality of life and physical function compared to those on a placebo.

Statistical Data

Research conducted by the Arthritis Foundation revealed that approximately 1.3 million adults in the United States are diagnosed with rheumatoid arthritis. This chronic autoimmune disease disproportionately affects more women than men, with women accounting for 75% of all cases.

Arava Dosage and Administration

When it comes to using Arava for rheumatoid arthritis, it is important to follow the prescribed dosage and administration guidelines to ensure optimal treatment outcomes. Here are some key points to keep in mind:

Dosage:

• The typical starting dose of Arava is 100 mg once daily for the first three days, followed by a maintenance dose of 20 mg to 30 mg once daily.
• Your healthcare provider may adjust the dosage based on your individual response to the medication and any side effects you may experience.

Administration:

• Arava is usually taken by mouth with or without food.
• It is important to take Arava exactly as prescribed by your healthcare provider to maximize its effectiveness.
• If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule.

By following the recommended dosage and administration guidelines, you can help ensure that Arava is working effectively to manage your rheumatoid arthritis symptoms.

How Arava Works

Arava is thought to work by inhibiting the activity of certain enzymes involved in the immune response. These enzymes play a role in the inflammation process that occurs in conditions like rheumatoid arthritis. By blocking these enzymes, Arava helps to reduce inflammation and prevent further joint damage in patients with rheumatoid arthritis.

Mechanism of Action

Arava acts as an immunosuppressive agent by inhibiting dihydroorotate dehydrogenase, an enzyme involved in pyrimidine synthesis crucial for DNA replication in lymphocytes. This mechanism suppresses the proliferation of T and B lymphocytes, thereby reducing the immune response that contributes to inflammation in rheumatoid arthritis.

Benefits of Arava

• Reduces joint pain and swelling
• Slows down joint damage progression
• Improves physical function and quality of life

Comparative Effectiveness

A study published in the Journal of Rheumatology compared the effectiveness of Arava to methotrexate, another commonly used DMARD for rheumatoid arthritis. The study found that Arava was comparable to methotrexate in reducing disease activity and improving physical function in patients with rheumatoid arthritis.

Side Effects

Common side effects of Arava include diarrhea, nausea, and hair loss. More severe side effects can include liver toxicity and lung problems. It is important for patients taking Arava to undergo regular monitoring of liver function and blood cell counts to detect any potential complications early.

Cost and Availability

Arava is available as tablets in various strengths, with an average retail price of $200 for a 30-day supply. It is usually covered by insurance plans, but copayments may vary depending on the specific plan. Generic versions of leflunomide are also available at a lower cost.

Arava Dosage and Administration
