What's the same
Celebrex and Voltaren both belong to the Pain Relief Medications class and are used for partially overlapping indications. The active ingredients — Celecoxib vs Diclofenac — share the same therapeutic approach, so many safety and management points carry across both.
Key differences
Meaningful differences are in active ingredient (Celecoxib vs Diclofenac), strengths (50mg, 100mg, 200mg, 400mg vs 25mg, 50mg, 75mg, 100mg), forms (capsule vs tablet, delayed-release tablet, topical gel, suppository), and the mechanism, half-life and side-effect nuances that distinguish members of the class.
Mechanism and action
Celebrex: Celecoxib selectively inhibits COX-2, the inducible isoform of cyclooxygenase upregulated at sites of inflammation, while sparing the constitutive COX-1 that maintains gastric mucosal integrity and platelet aggregation. Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen.
When Celebrex is preferred
