What Is the Role of Excipient Strategy in AEROTAB Ibuprofen?
AEROTAB Ibuprofen employs an innovative dry-powder inhaler (DPI) formulation designed for pulmonary delivery. Its excipient formulation focuses on optimizing drug dispersion, stability, and inhalation performance. Key excipients include amphiphilic phospholipids, spray-dried carbohydrate carriers, and surfactants.
The excipient selection influences:
- Powder flow characteristics: Ensured through carriers like mannitol or lactose.
- Particle dispersion: Achieved with surfactants such as lecithin.
- Stability and moisture protection: Provided by encapsulating agents.
This strategy aims to optimize bioavailability, minimize excipient-related side effects, and adapt to various inhalation devices.
