Leflunamide is used to treat:
- A. Crohn's disease
- B. Rheumatoid arthritis
- C. Psoriasis
- D. Photoallergic reactions
- E. None of the above.
The answer is (B) Rheumatoid arthritis.
Leflunomide is a disease-modifying antirheumatic drug (DMARD) that is used to treat rheumatoid arthritis, a chronic inflammatory autoimmune disease that affects the joints. It works by suppressing the immune system and reducing inflammation.
Leflunomide is also used to treat other autoimmune diseases, such as psoriatic arthritis and ankylosing spondylitis. However, it is not effective for treating Crohn's disease or photoallergic reactions.
The other options are incorrect:
- Crohn's disease is an inflammatory bowel disease that is treated with other medications, such as corticosteroids and biologics.
- Psoriasis is a chronic skin condition that is treated with topical medications, light therapy, and systemic medications.
- Photoallergic reactions are allergic reactions that are triggered by sunlight. They are treated with antihistamines and topical corticosteroids.
Leflunomide can have serious side effects, such as liver damage and bone marrow suppression. It is important to talk to your doctor about the risks and benefits of leflunomide before taking it.
