Biologic DMARDs include which of the following categories?

• A. TNF inhibitors
• B. Nonsteroidal anti-inflammatory drugs
• C. Antibiotics
• D. Antihistamines

Answer: (A)

Biologic DMARDs are therapies that directly target specific components of the immune system to slow autoimmune inflammation. They are typically monoclonal antibodies or receptor fusion proteins that interfere with key inflammatory signals. In particular, inhibitors of tumor necrosis factor alpha block a central driver of inflammatory cascades in diseases like rheumatoid arthritis and psoriatic arthritis.

The other options don’t fit as biologic DMARDs: NSAIDs provide symptomatic relief by reducing inflammation and pain but don’t alter disease progression; antibiotics target infections; antihistamines address allergic symptoms.

So the category that belongs to biologic DMARDs is TNF inhibitors.
