Advances in Inhalation Therapy: IBC Conference.

Area of Science:

• Pulmonary Medicine
• Pharmaceutical Sciences
• Biotechnology

Background:

• Inhalation therapy is a critical route for drug delivery, particularly for respiratory and systemic conditions.
• Significant advancements in aerosol drug delivery devices and formulations are emerging.
• The transition from chlorofluorocarbon (CFC)-based inhalers necessitates innovation in device design and drug stability.

Purpose of the Study:

• To summarize recent developments in inhalation therapy, covering device design, drug formulation, and assessment methods.
• To provide a clinical overview of the future prospects of aerosol drug therapy.
• To highlight novel approaches for enhanced drug delivery via inhalation.

Main Methods:

• A conference convened 16 experts to present and discuss recent progress in inhalation therapy.
• Review of current research and development in aerosol delivery devices, including pressurized metered dose inhalers (pMDIs), dry powder inhalers (DPIs), and soft mist inhalers (SMIs).
• Discussion on formulation strategies for both small molecules and macromolecules, including peptides and proteins, and advanced manufacturing techniques like supercritical fluid engineering.

Main Results:

• Reformulation of non-CFC pMDIs is progressing, though new hydrofluorocarbon (HFA)-based products may face limitations.
• Soft mist inhalers (SMIs) present a promising alternative to conventional pMDIs and DPIs, offering potential advantages in efficiency and aerosol delivery.
• Reproducible delivery of micronized macromolecules to the peripheral lung has shown success for peptides and insulin.
• Supercritical fluid engineering is enabling the development of 'smart drugs' for improved inhalation administration.

Conclusions:

• The field of inhalation therapy is experiencing rapid innovation across device technology and drug formulation.
• Emerging technologies like SMIs and advanced drug design offer enhanced potential for efficient and safe aerosol drug delivery.
• Inhalation therapy is poised to expand its role in routine drug administration, particularly for biologics like peptides and proteins.
