| Emerging markets |
$20–$50 |
Cost-sensitive, local regulations |
Reimbursement trends favor combination drugs, though cost pressures may lead to increased generic substitution.
Key Market Challenges and Competitive Risks
1. Patent Expiry & Generic Competition
- Proliferation of generic tobramycin and corticosteroid formulations post-2024 threatens price erosion.
- Limited patent protections for the combination product reduce exclusivity rights.
2. Regulatory & Policy Shifts
- Increased scrutiny on corticosteroids due to intraocular pressure risks may restrict labeling.
- Push for preservative-free formulations to mitigate side effects could disrupt current formulations.
3. Off-Label and Alternative Therapies
- Use of topical NSAIDs and newer anti-inflammatory biologics could challenge ZYLET's market share.
- Emerging drug delivery technologies (e.g., sustained-release inserts) may change administration paradigms.
