Which medication is classified as a non-steroidal anti-inflammatory drug and is a COX-2 inhibitor?

Celecoxib is classified as a non-steroidal anti-inflammatory drug (NSAID) and is specifically known as a COX-2 inhibitor. This classification is significant because COX-2 inhibitors are designed to target the cyclooxygenase-2 enzyme, which plays a crucial role in the inflammatory process. By inhibiting this enzyme, Celecoxib effectively reduces pain and inflammation without affecting the COX-1 enzyme, which is involved in protecting the stomach lining and supporting platelet function.

The other medications listed do not fall under the category of NSAIDs or COX-2 inhibitors. Estrogens (Conjugated) are hormones used primarily in hormone replacement therapy and do not possess anti-inflammatory properties. Lansoprazole is a proton pump inhibitor primarily used to reduce stomach acid and treat conditions like GERD, rather than to manage inflammation. Hydroxyzine Pamoate is an antihistamine that is mainly used for its anxiolytic properties and does not function as an anti-inflammatory. Understanding these classifications helps distinguish the specific uses and mechanisms of different medications in pharmacology.
