Market Dynamics: Drivers and Challenges
Key Drivers
- High Prevalence of GERD and Peptic Ulcers: Globally, GERD prevalence affects ~20% of the population in North America and Europe, supporting consistent demand.[2]
- Chronic Therapy Needs: Long-term safety profile of PPIs sustains prescriptions.
- Brand Loyalty and Physician Preference: Original innovator status and prescribed brand preference influence market share.
- Emerging Markets: Increasing urbanization and lifestyle-related gastrointestinal disorders expand potential markets.
Major Challenges
- Generic Competition and Price Erosion: Multiple generics significantly reduce profitability.
- Over-the-Counter (OTC) Sales: OTC availability diminishes prescription volume, compressing margins.
- Market Saturation: High penetration rates limit growth opportunities.
- Regulatory and Reimbursement Policies: Cost containment efforts by payers affect sales volume and pricing strategies.
- Alternative Therapies: Increasing use of H2 receptor antagonists and novel mechanisms of gastroprotection.
