Serious, potentially life-threatening skin reactions, including exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, or toxic epidermal necrolysis (TEN), have been reported during postmarketing surveillance of valdecoxib. Fatalities due to Stevens-Johnson syndrome or toxic epidermal necrolysis have been reported. While serious reactions may occur at any time during therapy with valdecoxib, the risk of such reactions appears to be highest within the first 2 weeks of therapy. While patients with a history of sulfonamide hypersensitivity may be at greater risk for skin reactions, patients without such a history also are at risk for serious skin reactions. These reactions are rare but have been reported at a greater frequency with valdecoxib than with other selective COX-2 inhibitors (e.g., celecoxib). Discontinue valdecoxib at the first appearance of a rash or any other manifestation of hypersensitivity.

Risk of potentially fatal GI ulceration, bleeding, and perforation. Most studies indicate less risk of GI ulceration than prototypical /SRP: NSAIDs/; however, the relative risk remains to be established. Use with caution in patients at risk for GI bleeding (e.g., history of GI bleeding or ulceration, treatment with oral corticosteroids or anticoagulants, longer duration of /SRP: NSAID/ therapy, geriatric patients, debilitation, smokers, or alcohol dependence). Consider alternative therapy in those at high risk for GI bleeding. ...

Severe (rarely fatal) anaphylactoid reactions have occurred in patients receiving /SRP: NSAIDs/, and anaphylactoid reactions (e.g., anaphylaxis, angioedema) have been reported during postmarketing surveillance of valdecoxib. Such reactions occurred in patients with or without a history of allergic-type reactions to sulfonamides. ...Cross-sensitivity between aspirin and other /SRP: NSAIDs/ may occur. Do not use in patients with bronchospastic aspirin sensitivity. Avoid use in patients with aspirin triad. Caution in patients with preexisting asthma, as bronchospasms may occur.

Conditions predisposing to and/or exacerbated by fluid retention (congestive heart disease or edema, pre-existing hypertension), valdecoxib may cause additive fluid retention or edema; also, risk of renal failure is increased in patients with congestive heart disease; valdecoxib should be initiated at the lowest dose in these patients).

Valdecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Valdecoxib is used for its anti-inflammatory, analgesic, and antipyretic activities in the management of osteoarthritis (OA) and for the treatment of dysmenorrhea or acute pain. Unlike celecoxib, valdecoxib lacks a sulfonamide chain and does not require CYP450 enzymes for metabolism.
Cyclooxygenase 2 Inhibitors

Absorption
Oral bioavailability is 83%.
Route of Elimination
Valdecoxib is eliminated predominantly via hepatic metabolism with less than 5% of the dose excreted unchanged in the urine and feces. About 70% of the dose is excreted in the urine as metabolites, and about 20% as valdecoxib N-glucuronide.
Volume of Distribution
86 L
Clearance
oral cl=6 L/h
6 7 L/h [In patients undergoing hemodialysis]
6 7 L/h [healthy elderly subjects]
At recommended doses, the mean oral bioavailability is 83%. The peak plasma concentration and area under the plasma concentration-time curve are roughly proportional across the clinical dose range. Valdecoxib may be coadministered with meals. Peak-plasma concentrations and extent of absorption were not affected after valdecoxib was taken with a high fat meal.

Time to peak concentration: Approximately 3 hours. Note: Time to peak concentration was delayed by 1 to 2 hours when administered with a high fat meal.

Steady state apparent volume of distribution (Vss/F) of valdecoxib is approximately 86 L after oral administration. Valdecoxib and its active metabolite preferentially partition into erythrocytes with a blood to plasma concentration ratio of about 2.5:1. This ratio remains approximately constant with time and therapeutic blood concentrations.

Hepatic (involves CYP3A4 and 2C9)
One active metabolite of valdecoxib has been identified in human plasma at approximately 10% the concentration of valdecoxib. This metabolite, which is a less potent COX-2 specific inhibitor than the parent also undergoes extensive metabolism and constitutes <2% of the valdecoxib dose excreted in the urine and feces. Due to the low concentration in the systemic circulation, it is not likely to contribute significantly to the efficacy profile of valdecoxib.
Physicians Desk Reference. 58th ed. Thomson PDR. Montvale, NJ 2004., p. 2574
In humans, valdecoxib undergoes extensive hepatic metabolism involving both P450 isoenzymes (3A4 and 2C9) and non-P450 dependent pathways (i.e., glucuronidation).

Valdecoxib has known human metabolites that include 4-[3-(3-hydroxyphenyl)-5-methyl-1,2-oxazol-4-yl]benzene-1-sulfonamide and 4-[5-(hydroxymethyl)-3-phenyl-1,2-oxazol-4-yl]benzene-1-sulfonamide.

Both COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandin (PG) H2, the precursor of PGs and thromboxane. Valdecoxib selectively inhibits the cyclooxygenase-2 (COX-2) enzyme, important for the mediation of inflammation and pain. Unlike non-selective NSAIDs, valdecoxib does not inhibit platelet aggregation.
Valdecoxib is a nonsteroidal anti-inflammatory drug (NSAID) with antiinflammatory, analgesic, and antipyretic therapeutic effects. It has been proposed that valdecoxib inhibits the activity of the enzyme cyclooxygenase-2 (COX-2), resulting in a decreased formation of precursors of prostaglandins. However, unlike most NSAIDs, valdecoxib does not inhibit cyclooxygenase-1 (COX-1) isoenzyme in humans at therapeutic concentrations.
