Tauxib

Tauxib - General Information

Tauxib is a new COX-2 selective inhibitor. Current therapeutic indications are: treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, chronic low back pain, acute pain and gout. Like any other COX-2 selective inhibitor, Tauxib selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2). This reduces the generation of prostaglandins (PGs) from arachidonic acid.

Pharmacology of Tauxib

Tauxib is a COX-2 selective inhibitor (approximately 106 times more selective for COX-2 inhibition over COX-1). Currently it is approved in more than 60 countries worldwide but not in the US, where the Food and Drug Administration (FDA) require additional safety and efficacy data for etoricoxib before it will issue approval.

Additional information about Tauxib

Tauxib Indication: For the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, chronic low back pain, acute pain and gout.
Mechanism Of Action: Like any other COX-2 selective inhibitor Tauxib selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2). This reduces prostaglandins (PGs) generation from arachidonic acid.
Drug Interactions: Anisindione Tauxib increases the anticoagulant effect
Dicumarol Tauxib increases the anticoagulant effect
Acenocoumarol Tauxib increases the anticoagulant effect

Drug Type: Small Molecule; Approved

Other Brand Names containing Etoricoxib: Arcoxia; Nucoxia; Tauxib; Algix;
Absorption: Bioavailability is 100% following oral administration.
Toxicity (Overdose): This reduced activity is the cause of reduced gastrointestinal toxicity, as demonstrated in several large clinical trials performed with different COXIB (see below links on NEJM and The Lancet). Some clinical trials and meta-analysis showed that treatment with COXIB lead to increased incidence of cardiovascular adverse events compared to placebo
