Which of the following drugs is classified as a DMARD?

The classification of DMARDs, or disease-modifying anti-rheumatic drugs, is specifically aimed at treating inflammatory conditions such as rheumatoid arthritis by slowing disease progression and preventing joint damage. Enbrel (Etanercept) is an example of a DMARD because it is a biologic agent that specifically targets tumor necrosis factor (TNF), a substance in the body that leads to inflammation. By inhibiting TNF, Enbrel helps reduce the symptoms and progression of autoimmune diseases.

In contrast, the other medications listed serve different purposes. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) primarily used for pain relief and reducing inflammation, but it does not modify the disease process itself. Tylenol (acetaminophen) is primarily an analgesic and antipyretic, effective for pain and fever but not for inflammation or disease progression in autoimmune disorders. Albuterol is a bronchodilator used primarily for asthma and other respiratory conditions, not for treating autoimmune diseases. Thus, Enbrel stands out as the only medication among the options that modifies the underlying disease rather than just alleviating symptoms.
