Inhalation grade particles
Inhalation grade particle generation strategies
Within inhalation drug development services, Hovione focuses on the development of enabling particle engineering solutions for inhalation drug development, while maintaining tight control over conventional development techniques.
Hovione has developed its own toolkit to address the requirements of a new generation of inhalation grade particles, including bottom-up approaches such as controlled microcrystallization and top-down approaches, such as air jet milling, spray drying and wet polishing.
Air jet milling
|Strengths||• Target PS in a single step||• Control over PS and distribution
• Tailoring morphology and surface properties
• Scalable approaches available
|Limitations||• Process and scale-up complexity
• Wide PS distribution, agglomeration
• Limited morphology tuning
|• Requires isolation step for wet methods
• Challenges for thermolabile molecules
