DESCRIPTION
Parecoxib sodium is a white to off-white solid that is very soluble in
water. The
formulated drug product is soluble in normal (0.9%) saline at >50
mg/mL.
Powder for Injection and Powder and Diluent for Injection
PARECOXB Injection is a white to off-white, preservative-free,
lyophilised powder
in a single-use vial. For intravenous (IV) or intramuscular (IM)
administration,
PARECOXB Injection should be reconstituted with 2 mL sodium chloride
solution
(0.9% w/v), or a suitable alternative (see DOSAGE AND ADMINISTRATION).
Reconstituted Solution
The reconstituted solution is clear and colourless.
PARECOXB Injection 40 mg contains parecoxib sodium, sodium
phosphate-dibasic
anhydrous; phosphoric acid and/or sodium hydroxide may have been added
to adjust pH.
When reconstituted in sodium chloride solution (0.9% w/v), PARECOXB
Injection
contains approximately 0.44 mEq of sodium per 40 mg vial.
PHARMACOLOGY
Pharmacological Actions
PHARMACODYNAMICS
Following injection, parecoxib sodium is rapidly converted to
valdecoxib: the _in vivo _
pharmacology of parecoxib is therefore that of valdecoxib. The
mechanism of action
of valdecoxib is by inhibition of cyclooxygenase-2 (COX-2)-mediated
prostaglandin
synthesis. At therapeutic plasma concentrations in humans, valdecoxib
does not
inhibit cyclooxygenase-1 (COX-1). In animal models, valdecoxib is
anti-inflammatory,
analgesic, and antipyretic.
By inhibition of both peripheral and central COX-2, valdecoxib reduces
the production
of prostaglandins that are important mediators of pain and
inflammation. Therefore,
PARECOXB Injection is not expected to exhibit the potential for
