Bioequivalence of azathioprine products.

All azathioprine oral tablets are considered bioequivalent by the Food and Drug Administration based on traditional testing. However, since these tests were conducted, it has been determined that some patients have a deficiency of the enzyme most responsible for the metabolism of 6-mercaptopurine-thiopurine methyltransferase (TPMT). Azathioprine is rapidly converted to 6-mercaptopurine, its active metabolite. So it is possible that differences in TPMT activity may influence the bioequivalence of azathioprine products among individuals, especially those patients deficient in TPMT enzyme activity. However, this possibility has not been evaluated.

Valdecoxib.

Valdecoxib is a selective COX-2 inhibitor that is similar in anti-inflammatory activity to the other selective COX-2 inhibitors (e.g., celecoxib and rofecoxib). Valdecoxib is at least equally as effective as ibuprofen, naproxen, and diclofenac in the treatment of osteoarthritis and rheumatoid arthritis, but is safer in terms of gastrointestinal toxicity. Valdecoxib is also indicated for treatment of dysmenorrhea and useful in other pain conditions. There have been no head-to-head comparisons of valdecoxib and celecoxib or rofecoxib in the treatment of osteoarthritis, rheumatoid arthritis, or various pain conditions.
