What is the primary treatment use for Celebrex?

Celebrex, known generically as celecoxib, is primarily used for the treatment of osteoarthritis. It is classified as a nonsteroidal anti-inflammatory drug (NSAID) and works by inhibiting an enzyme called cyclooxygenase-2 (COX-2), which plays a crucial role in the production of prostaglandins that mediate inflammation and pain. By reducing inflammation, Celebrex alleviates the pain and stiffness associated with osteoarthritis, making it an effective choice for managing this condition.

In stark contrast, the other options do not align with the primary therapeutic use of Celebrex. It does not manage diabetes, as that would require medications targeting insulin regulation or glucose metabolism. Celebrex is not indicated for the treatment of anxiety disorders; such conditions typically require medications like SSRIs or benzodiazepines. Additionally, while it may have some effects related to muscle function, it is not designed to manage muscle spasticity, which would involve medications specifically targeting neuromuscular conditions. Thus, the correct answer focuses on Celebrex's established role in treating osteoarthritis.
