What Are the Market Drivers for Corticosteroids in S02B?
Therapeutic Demand and Clinical Applications
Corticosteroids are synthetic analogs of endogenous steroid hormones, primarily used to reduce inflammation, suppress immune responses, and treat conditions such as:
- Oral mucositis
- Periodontal diseases
- Allergic stomatitis
- Postoperative inflammation
The increasing prevalence of oral inflammatory conditions—driven by aging populations and rising chronic disease incidence—stimulates continuous demand. For instance, the global prevalence of periodontal disease is estimated at 50%, impacting over 1 billion people globally, fueling the corticosteroid segment [1].
