Description

Valdecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Valdecoxib was manufactured and marketed under the brand name Bextra. Bextra was indicated for relief of the signs and symptoms of osteoarthritis and adult rheumatoid arthritis. For the treatment of primary dysmenorrhea. But in 2005 FDA requested that Pfizer withdraw Bextra from the American market, because the Agency had concluded that the overall risk versus benefit profile of Bextra was unfavorable. That conclusion was based on the potential increased risk for serious cardiovascular (CV) adverse events, an increased risk of serious skin reactions (e.g., toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme) compared to other NSAIDs, and the fact that Bextra had not been shown to offer any unique advantages over the other available NSAIDs.

Sample Use Guides

In Vivo Use Guide

Osteoarthritis and Adult Rheumatoid Arthritis: the recommended dose of BEXTRA Tablets (VALDECOXIB) for the relief of the signs and symptoms of arthritis is 10 mg once daily. Primary Dysmenorrhea: the recommended dose of BEXTRA Tablets for treatment of primary dysmenorrhea is 20 mg twice daily, as needed.

Route of Administration: Oral

In Vitro Use Guide

Valdecoxib potently inhibits recombinant COX-2, with an IC50 of 0.005 uM. Unique binding interactions of valdecoxib with COX-2 translate into a fast rate of inactivation of COX-2 (110,000 M/s). The overall saturation binding affinity for COX-2 of valdecoxib is 2.6 nM. Valdecoxib inhibits COX-1 in a competitive fashion only at very high concentrations IC50= 150 uM.
