Generic Arava Information

Introduction

Arava is a disease‑modifying medication whose active compound is leflunomide, an immunomodulatory agent classified within the general health group of drugs. It is primarily prescribed for the long‑term management of moderate to severe rheumatoid arthritis (RA) in adult patients. In Hong Kong, leflunomide is listed in the Hospital Authority’s formulary for rheumatologic conditions and can be obtained through licensed pharmacies with a physician’s prescription. The drug may also be considered for off‑label use in other inflammatory arthritides when standard therapies are insufficient.

What is Arava?

Arava is a tablet formulation containing the active ingredient leflunomide. The product is manufactured by Santen Pharmaceutical Co., Ltd., an international firm that developed leflunomide for clinical use in the early 199s. Leflunomide belongs to the class of pyrimidine synthesis inhibitors and functions as an immunosuppressive agent. While Arava itself is not a brand name in every market, it is recognized in Hong Kong and several Asian territories as a licensed preparation of leflunomide.

How Arava Works

Leflunomide, the core molecule in Arava, selectively inhibits the enzyme dihydroorotate dehydrogenase (DHODH). DHODH is essential for the de‑novo synthesis of pyrimidine nucleotides, which are required for the proliferation of activated T‑lymphocytes and B‑cells. By limiting pyrimidine production, leflunomide reduces the expansion of immune cells that drive joint inflammation.

The therapeutic effect typically emerges within 4–8 weeks of consistent dosing, reflecting the time needed for immune modulation and the gradual decline of the active metabolite teriflunomide, which has a long elimination half‑life (approximately 15 days). Steady‑state concentrations are reached after 3–4 weeks of daily therapy, supporting sustained disease control.

Conditions Treated with Arava

• Rheumatoid arthritis (RA): Approved for adults with moderate to severe disease who have an inadequate response to at least one conventional disease‑modifying antirheumatic drug (DMARD).
• Psoriatic arthritis (PsA): Although not formally listed in the Hong Kong product label, clinical guidelines recognize leflunomide as a therapeutic option in patients with peripheral joint involvement unresponsive to first‑line agents.
• Juvenile idiopathic arthritis (JIA) – adult onset: Occasionally considered off‑label for adult patients with persistent arthritis after failure of methotrexate or biologics.

RA prevalence in Hong Kong is estimated at .4–.5 % of the adult population, representing thousands of potential candidates for leflunomide therapy. The drug’s oral administration, once‑daily dosing, and demonstrated efficacy in reducing joint swelling and pain make it a valuable component of the local treatment armamentarium.

Patient Groups Most Likely to Benefit

• Adults (≥18 years) with active RA who have experienced insufficient symptom control with methotrexate, sulfasalazine, or hydroxychloroquine.
• Patients preferring oral therapy over injectable biologics, particularly those with limited access to infusion centers.
• Individuals with renal impairment (mild to moderate) because leflunomide is primarily metabolized hepatically; dose adjustment may be unnecessary but monitoring is advised.

Contraindications include severe hepatic dysfunction, pregnancy, breastfeeding, and known hypersensitivity to leflunomide or any of its excipients. Patients with active infections, especially tuberculosis or hepatitis B/C, should avoid initiation until the infection is adequately managed.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset: nausea, abdominal pain, and diarrhoea are reported in up to 15 % of users.
• Elevated liver enzymes: alanine transaminase (ALT) and aspartate transaminase (AST) elevations occur in approximately 10 % of patients; routine monitoring is recommended.
• Hypertension: systolic or diastolic blood pressure increases observed in 5–8 % of individuals, particularly those with pre‑existing cardiovascular risk factors.
• Hair thinning or mild alopecia: reversible upon discontinuation.

Rare

• Peripheral neuropathy: sensory changes or tingling reported in <2 % of patients; dose reduction may alleviate symptoms.
• Cutaneous reactions: rash, photosensitivity, or Stevens‑Johnson‑like eruptions are uncommon but require immediate medical evaluation.
• Bone marrow suppression: modest reductions in white blood cell counts have been documented; routine CBC monitoring is advisable.

Serious

• Hepatotoxicity: severe liver injury, including hepatitis and liver failure, can occur; any sign of jaundice or marked transaminase rise mandates cessation and specialist referral.
• Severe infections: leflunomide’s immunosuppressive action predisposes to opportunistic infections; clinicians should screen for latent tuberculosis and viral hepatitis before starting therapy.
• Pregnancy‑related teratogenicity: leflunomide is contraindicated in pregnancy due to the risk of fetal malformations; a “wash‑out” accelerated elimination procedure using cholestyramine or activated charcoal is required if pregnancy occurs or is planned.

Drug–Drug Interactions

• Immunosuppressants (e.g., azathioprine, cyclophosphamide): additive myelosuppression may increase infection risk.
• Warfarin: leflunomide may enhance anticoagulant effect, necessitating closer INR monitoring.
• Cytochrome P450 inducers/inhibitors (e.g., rifampin, ketoconazole): can alter teriflunomide plasma levels, affecting efficacy and toxicity.
• Live vaccines: administration should be avoided while on leflunomide, as immune response may be blunted and infection risk heightened.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dosing: most clinicians start with 20 mg orally once daily for the first 5 days, followed by a maintenance dose of 10–20 mg once daily depending on disease activity and tolerability.
• Dose adjustments: if hepatic enzymes rise >2× upper limit of normal, consider reducing to 10 mg daily or temporarily interrupting therapy.
• Missed dose: if a single dose is missed, take it as soon as remembered unless it is near the time of the next scheduled dose; then skip the missed dose and continue the regular schedule. Doubling doses is not recommended.
• Overdose: ingestion of >100 mg (≈5 tablets) may cause severe hepatotoxicity and hypertension. Seek emergency medical care; activated charcoal within 1 hour of ingestion can reduce absorption.
• Precautions:
  • Take tablets with food or water to minimise gastrointestinal irritation.
  • Avoid excessive alcohol, which can amplify liver injury.
  • Counsel patients about the need for regular laboratory monitoring (LFTs, CBC, blood pressure) every 2–4 weeks during the first three months, then at three‑monthly intervals.
  • Women of child‑bearing potential must use reliable contraception throughout treatment and for at least 2 years after discontinuation due to the drug’s prolonged half‑life.

• Are there any known differences in formulation between regions?
  The leflunomide active ingredient is chemically identical worldwide. However, excipient composition may vary slightly among manufacturers; Hong Kong‑approved products meet local pharmacopeial standards.

• Can Arava be combined with biologic therapies?
  Leflunomide is often used in conjunction with biologic DMARDs (e.g., infliximab, etanercept) to enhance disease control. Monitoring for additive immunosuppression and infection risk is essential.

• What monitoring schedule is recommended for patients on Arava?
  Baseline liver function tests, complete blood count, and blood pressure should be obtained before initiation. Follow‑up labs are recommended every 2–4 weeks during the first three months, then quarterly thereafter.

• Does Arava have any specific warnings for Asian patients?
  No ethnicity‑specific contraindications have been identified. However, clinicians should be vigilant for hepatotoxicity, as some Asian populations have higher rates of viral hepatitis.

• Is there an accelerated wash‑out protocol for leflunomide?
  Yes, a 2‑day course of cholestyramine (4 g every 8 hours) or activated charcoal (50 g every 6 hours for 12 hours) can hasten teriflunomide elimination, especially in cases of pregnancy or severe toxicity.

• Can telemedicine services prescribe Arava for ongoing rheumatoid arthritis management?
