Arava – An Effective Treatment for Rheumatoid Arthritis and Psoriatic Arthritis

Arava: An Overview

Arava is a prescription medication that is commonly 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 body.

Here are some key points about Arava:

  • Indications: Arava is primarily used in the treatment of rheumatoid arthritis and psoriatic arthritis, both of which are chronic autoimmune diseases that cause joint inflammation and pain.
  • Mechanism of action: Arava works by inhibiting the activity of certain immune cells called lymphocytes, which play a role in the inflammation and destruction of joints seen in arthritis.
  • Active ingredient: The active ingredient in Arava is leflunomide, a synthetic compound that directly targets the underlying mechanisms of arthritis.
  • Administration: Arava is taken orally in the form of tablets. The dosage and duration of treatment may vary depending on the individual’s condition and response to the medication.
  • Effectiveness: Studies have shown that Arava can significantly improve the symptoms of rheumatoid arthritis and psoriatic arthritis, including joint pain, swelling, and stiffness. It can also help slow down the progression of joint damage and disability associated with these conditions.
  • Side effects: Like all medications, Arava can cause side effects. Common side effects include nausea, diarrhea, stomach pain, and hair loss. Rare but serious side effects include liver problems and severe skin reactions. It is important to discuss potential risks and benefits with your healthcare provider before starting Arava.
  • Safety considerations: Arava is contraindicated in pregnant women, as it may cause harm to the developing fetus. It is also important to undergo regular blood tests to monitor liver function while taking Arava, as it can potentially affect liver health.
  • Alternatives: There are other DMARDs available for the treatment of rheumatoid arthritis and psoriatic arthritis, including methotrexate, sulfasalazine, and biologic agents. The choice of medication depends on various factors, such as the severity of the disease, response to treatment, and individual patient preferences.

In conclusion, Arava is a widely used medication for the management of rheumatoid arthritis and psoriatic arthritis. It is an effective DMARD that helps reduce joint inflammation and improve symptoms. However, it is important to work closely with your healthcare provider to determine the most suitable treatment approach for your specific condition.

2. How does Arava work?

Arava works by suppressing the body’s immune system, which helps to reduce inflammation and slow down the progression of rheumatoid arthritis and psoriatic arthritis.

Unlike other common medications for arthritis, such as nonsteroidal anti-inflammatory drugs (NSAIDs), Arava is a disease-modifying antirheumatic drug (DMARD). DMARDs are designed to target the underlying cause of arthritis and modify the disease process.

Arava specifically inhibits the action of an enzyme called dihydroorotate dehydrogenase (DHODH). This enzyme is involved in the production of DNA and RNA, which play essential roles in the division and growth of cells, including immune cells.

By inhibiting DHODH, Arava helps to suppress the overactive immune response that occurs in arthritis. This reduces inflammation and pain, and prevents damage to the joints.

Arava is an oral medication that is usually taken once daily. The dosage and duration of treatment may vary depending on the individual’s condition and response to the medication. It is important to follow the instructions provided by the healthcare professional or stated on the prescription label.

It is worth noting that Arava may take several weeks or months to show its full effects. Therefore, it is important to continue taking the medication as prescribed, even if there are no immediate improvements in symptoms.

Steering away from using this medication without medical guidance is crucial, as Arava can have potential side effects. These include liver problems, lung disease, and low blood cell counts. Regular monitoring of liver function and blood counts is necessary during Arava treatment.

The dosage of Arava for the treatment of rheumatoid arthritis may vary depending on the individual’s condition and response to treatment. The recommended initial dosage is 100 mg once daily for three days, followed by a maintenance dosage of 20 mg to 30 mg once daily. It is important to follow the dosage instructions provided by your healthcare professional.

Please note that it may take several weeks to months for Arava to show its full effect, and it is recommended to continue taking the medication even if immediate improvement is not observed.

3.2 Dosage for Psoriatic Arthritis:

For psoriatic arthritis, the dosage of Arava is similar to that of rheumatoid arthritis. The recommended initial dosage is 100 mg once daily for three days, followed by a maintenance dosage of 20 mg to 30 mg once daily. Your doctor will determine the appropriate dosage for your condition based on various factors.

It is advised to avoid drinking alcohol while taking Arava, as it may increase the risk of liver damage. Regular liver function tests should be conducted to monitor any potential side effects.

3.4 Special Considerations:

Special considerations may be required for patients with liver problems, impaired kidney function, or certain types of infections. It is important to inform your doctor of any underlying health conditions or medications you are taking before starting Arava treatment.

Additionally, Arava should not be taken during pregnancy, as it may cause harm to the unborn baby. Use of effective contraception is advised for both men and women during treatment and for a certain period after stopping Arava, as the medication may remain in the body for a prolonged duration.
