Algix - General Information
Algix 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, Algix selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2). This reduces the generation of prostaglandins (PGs) from arachidonic acid.
Pharmacology of Algix
Algix 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 Algix
Algix 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 Algix selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2). This reduces prostaglandins (PGs) generation from arachidonic acid.
Drug Interactions: Anisindione Algix increases the anticoagulant effect
Dicumarol Algix increases the anticoagulant effect
Acenocoumarol Algix increases the anticoagulant effect
Warfarin Algix increases the anticoagulant effect
Ethinyl Estradiol Algix increases levels of ethinyl estradiol
Lithium Algix increases serum levels of lithium
Rifampin Rifampin reduces levels and efficacy of etoricoxib

Generic Name: Etoricoxib
Synonyms: Not Available
Drug Category: Cyclooxygenase Inhibitors
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
