Market Growth Factors
- Patent Expiry & Generics: The US patent for CLINORIL expired in 2008, leading to a proliferation of generic loratadine products. Future patent protections are limited, with some extended exclusivity in key regions (e.g., pediatrics in the US).
- Regulatory Expansion: Approvals for new indications and formulations contribute to growth.
- Consumer Preference Shifts: Preference for non-drowsy, longer-acting antihistamines fuels innovation.
- Emerging Market Penetration: Growing healthcare infrastructure in Asia and Africa expands access.
