Alternative names include Célécoxib and Celecoxibum, providing insight into its chemical composition.

Brand Names and Packaging Options

In Canada, Celecoxib is primarily distributed under the brand name Celebrex. Patients can find it in various packaging formats, such as blister packs and bottles containing either 30 or 100 capsules. The availability of generics has broadened options for consumers seeking cost-effective treatments. These generic versions maintain the same active ingredient, ensuring similar therapeutic effects.

Classification and ATC Codes

Celecoxib falls into two ATC classifications: M01AH01 for Coxibs (COX-2 selective NSAIDs) and L01XX33 for other antineoplastic agents used in familial adenomatous polyposis. This classification highlights its dual application in relieving inflammation and its potential adjunctive role in cancer treatment.

Dosage Forms Available

Patients can find Celecoxib in various dosage forms. The most common are capsules available in strengths of 50mg, 100mg, 200mg, and 400mg.

Exploring the Pharmacology of Celecoxib

Understanding how Celecoxib works can clarify its role in inflammation management and pain relief. This medication reduces inflammation by specifically blocking an enzyme known as COX-2, resulting in decreased prostaglandin synthesis.

Mechanism of Action

In simple terms, Celecoxib plays a vital role in reducing inflammation and pain by inhibiting COX-2. Clinically, this selective inhibition translates to a decrease in the production of prostaglandins, substances in the body that mediate inflammation.

Onset and Duration of Action

When administered, the onset of action for Celecoxib typically ranges from 24 to 48 hours, making it a suitable option for managing chronic and acute pain. The bioavailability is notable with a half-life of approximately 11 hours, further birthing its efficiency in prolonged pain management.

Metabolism and Elimination

Metabolized primarily in the liver via the cytochrome P450 pathway, Celecoxib is predominantly excreted through feces. This metabolic pathway should be duly considered, especially when managing patients with liver impairments.

Drug Interactions

Celecoxib does interact with several other medications, notably anticoagulants and other NSAIDs. The potential for increased side effects necessitates caution and patient education. Hence, patients are often advised to avoid taking other NSAIDs and excessive alcohol during their treatment with Celecoxib.

Conclusion

Celecoxib is a crucial option for many patients suffering from inflammatory conditions. With its diverse dosage forms, comprehensive understanding of its pharmacology can empower both patients and healthcare providers in managing pain effectively and safely.
