In this article, we will discuss CELEBREX ™ (Celecoxib). So, let’s get started.
Celecoxib Selective COX-2 inhibitor. It should be used in patients at high risk of peptic ulcer, perforation or gastrointestinal bleeds. It is the only FDA approved selective COX-2 inhibitor recommended for use in juvenile idiopathic arthritis. CELEBREX (celecoxib) is chemically designated as 4-15-(4-methylphenyl)-3- (trifluoromethyl)-1H-pyrazol-1-yl) benzenesulfonamide and is a diaryl substituted pyrazole.
The empirical formula for celecoxib is C17H14F3N3O2S, and the molecular weight is 381.38.
Mechanism of Action
CELEBREX is a nonsteroidal anti-inflammatory drug that exhibits anti-inflammatory, analgesic, and antipyretic activities in animal models. The mechanism of action of CELEBREX is believed to be due to inhibition of prostaglandin synthesis, primarily via inhibition of cyclooxygenase-2 (COX-2), and at therapeutic concentrations in humans, CELEBREX does not inhibit the cyclooxygenase-I (COX-1) isoenzyme.
