Valus Xt
Valus Xt Uses, Dosage, Side Effects, Food Interaction and all others data.
Valus Xt was removed from the Canadian, U.S., and E.U. markets in 2005 due to concerns about a possible increased risk of heart attack and stroke.
Valus Xt, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Valus Xt 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.

Valus Xt is a COX-2 inhibitor used to treat osteoarthritis and dysmenorrhoea.
For the treatment of osteoarthritis and dysmenorrhoea
Valus Xt is also used to associated treatment for these conditions: Osteoarthritis (OA), Primary Dysmenorrhoea, Rheumatoid Arthritis
How Valus Xt works
Both COX-1 and COX-2 catalyze the conversion of arachidonic acid to prostaglandin (PG) H2, the precursor of PGs and thromboxane. Valus Xt 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.
Toxicity
Symptoms following acute NSAID overdoses are usually limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which are generally reversible with supportive care. Gastrointestinal bleeding can occur. Hypertension, acute renal failure, respiratory depression and coma may occur, but are rare.
Food Interaction
- Avoid alcohol. Ingesting alcohol may increase the risk of gastrointestinal bleeding.
- Take with or without food.
