Which NSAIDs are classified as fenamates?

The correct answer identifies meclofenamate and mefenamic acid as the NSAIDs that are classified as fenamates. Fenamates are a class of nonsteroidal anti-inflammatory drugs that are derived from anthranilic acid. Both meclofenamate and mefenamic acid belong to this group and are used to alleviate pain, inflammation, and fever.

These drugs work by inhibiting the cyclooxygenase (COX) enzymes, which play a critical role in the production of prostaglandins, compounds involved in the inflammatory response. Due to their structure and mechanism of action, they are specifically categorized under the fenamate class.

In contrast, the other options list NSAIDs that do not belong to the fenamate classification. Indomethacin and sulindac are classified as indole and indene derivatives, respectively. Diclofenac and tolmetin belong to a different category of NSAIDs, as do ketorolac and meloxicam. Understanding these classifications is crucial for recognizing the pharmacological profiles and potential side effects associated with each class of medications in pain management.
