Biochem/physiol Actions

Rofecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor with >800-fold COX-2 selectivity in CHO cells expressing human COX-1 and COX-2.
Rofecoxib is derived from furanone and has the ability to cross human placenta. Along with anti-inflammatory action, it possesses analgesic and antipyretic properties. Cytosolic hepatic enzymes are responsible for the metabolism of rofecoxib. It is known to cause oligohydramnios and ductus arteriosus constrictions. Rofecoxib inhibits the action of CYP1A2 (cytochrome P450 family 1 subfamily A member 2). It might be associated with aseptic meningitis. Rofecoxib is known to ameliorate the risk of colorectal adenoma, but might contribute to toxicity.

2,5-Dimethyl-celecoxib (DMC) is a close structural analog of the selective cyclooxygenase-2 (COX-2) inhibitor celecoxib (Celebrex) that lacks COX-2-inhibitory function. However, despite its inability to block COX-2 activity, DMC is able to potently mimic the anti-tumor effects of celecoxib in vitro

There is concern that cyclooxygenase (COX)-2 inhibitors may promote atherothrombosis by inhibiting vascular formation of prostacyclin (PGI2) and an increased thrombotic risk of COX-2 inhibitors has been reported. It is widely accepted that the prothrombotic effects of COX-2 inhibitors can

Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase (COX) activity, which is the rate-limiting enzyme in the synthesis of prostaglandins. Previous studies have indicated that NSAID therapy, and in particular NSAIDs that specifically target the inflammatory cyclooxygenase (COX-2), impair bone healing. We

Many countries lack fully functional pharmacovigilance programs, and public budgets allocated to pharmacovigilance in industrialized countries remain low due to resource constraints and competing priorities. Using 3 case examples, we sought to estimate the public health and economic benefits resulting
