J Cotter and Eric Wooltorton highlight the importance of differences in cyclooxygenase 2 (COX-2) selectivity as a potential explanation for the prothrombotic effects of coxibs. However, they neglect important evidence that celecoxib might not share the same cardiovascular (CV) risk as rofecoxib. An increased thrombotic risk with celecoxib has been demonstrated only in the APC (Adenoma Preventio...

The aim of the present study was to compare the pre-emptive use of a cyclooxygenase-2 (COX-2) inhibitor with a well established steroidal anti-inflammatory drug for pain and edema relief following periodontal surgery for crown lengthening. Thirty patients requiring periodontal surgery were randomly assigned to receive one of the following medications: selective COX-2 inhibitor or steroidal anti...

BACKGROUND The aim of this study was to determine compliance with published good practice guidelines for gender and clinical trials using etoricoxib. The rationale for choosing etoricoxib was that it is widely used by women and there is evidence of potential interaction with contraceptives and hormone replacement therapy as highlighted in the product characteristics. METHODS The study reviewe...

INTRODUCTION Valdecoxib is a cyclooxygenase-2 (COX-2) selective anti-inflammatory drug. It is associated with a reduced incidence of gastrointestinal complications and is potentially useful for patients with rheumatological diseases requiring longer term anti-inflammatory treatment. AREAS COVERED Due to a perceived increased risk of thrombotic events, particularly cardiovascular hazards and r...

In mammalian cells, eicosanoid biosynthesis is usually initiated by the activation of phospholipase A(2) and the release of arachidonic acid from membrane phospholipids in response to the interaction of a stimulus with a receptor on the cell surface. Arachidonic acid is subsequently transformed by the enzyme cyclooxygenase (COX) to prostaglandins (PGs) and thromboxane (TX). The COX pathway is o...

Evaluating the impact of Viola spathulata in a rat model brain ischemia/reperfusion by influencing expression level caspase-3 and cyclooxygenase-2

Introduction: cyclooxygenase-2 (COX-2) is involved in pathogenesis of various tumors and possibly malignant skin tumors including malignant melanoma; however, there is not enough information about COX-2 expression in benign melanocytic lesions. In the present study we compared the expression levels of COX-2 in malignant melanoma and benign melanocytic lesions. Method: In this analytical study, ...
