Recent findings suggest that modulation of ion channels might be implicated in some of the clinical effects of coxibs, selective inhibitors of cyclooxygenase-2 (COX-2). Celecoxib and its inactive analog 2,5-dimethyl-celecoxib, but not rofecoxib, can suppress or augment ionic currents and alter functioning of neurons and myocytes. To better understand these unexpected effects, we have recently i...
BACKGROUND Two strategies for prevention of upper gastrointestinal (UGI) events for nonselective nonsteroidal anti-inflammatory drug (nsNSAID) users are replacement of the nsNSAID by a cyclo-oxygenase-2-selective inhibitor (coxib) or co-prescription of a gastroprotective agent (GPA). AIM To identify whether and in whom either of these strategies should be preferred in daily practice. METHOD...
A drawback of extensive coxib use for antitumor purposes is the risk of life-threatening side effects that are thought to be a class effect and probably due to the resulting imbalance of eicosanoid levels. 2,5-Dimethyl-celecoxib (DMC) is a close structural analogue of the selective cyclooxygenase-2 inhibitor celecoxib that lacks cyclooxygenase-2-inhibitory function but that nonetheless is able ...
OBJECTIVES To assess short term efficacy and tolerability of a therapeutic strategy in patients with ankylosing spondylitis (AS) unresponsive to nonsteroidal anti-inflammatory drugs (NSAIDs) or coxibs and unable to take anti-tumour necrosis factor-alpha (anti-TNFalpha) biological treatment. METHODS Established AS patients were given a background treatment consisting of subcutaneous injections...
Cyclooxygenase-2 (COX-2) is constitutively expressed and highly regulated in the thick ascending limb (TAL). As COX-2 inhibitors (Coxibs) increase COX-2 expression, we tested the hypothesis that a negative feedback mechanism involving PGE(2) EP3 receptors regulates COX-2 expression in the TAL. Sprague-Dawley rats were treated with a Coxib [celecoxib (20 mg·kg(-1)·day(-1)) or rofecoxib (10 mg·kg...
