Pharmacology
Celecoxib is a selective COX-2 inhibitor that reduces prostaglandin synthesis in peripheral tissues and the CNS, producing analgesic, anti-inflammatory, and antipyretic effects; at therapeutic doses it does not inhibit platelet aggregation or prolong bleeding time.
TNF-alpha antagonist; infliximab-abda is a chimeric IgG1kappa monoclonal antibody that neutralizes TNF-alpha by binding with high affinity to soluble and transmembrane forms of TNF-alpha, inhibiting receptor binding and suppressing downstream pro-inflammatory activity.
