Market Size and Growth
The global diclofenac sodium market was valued at approximately $1.15 billion in 2022. The market is expected to grow at a compound annual growth rate (CAGR) of around 4% from 2023 to 2028, driven by increased prevalence of chronic inflammatory diseases and expanding approval of topical formulations.
Market Segments
-
Formulation:
- Oral tablets and capsules comprise the largest segment, accounting for about 60% of sales.
- Topical gels and patches represent around 25%.
- Injectable forms contribute 15% but are used in specific clinical settings.
-
Geography:
- North America holds the largest share at approximately 40%, driven by established healthcare infrastructure, high disease prevalence, and brand presence.
- Europe accounts for 30%, with growth fueled by aging populations.
