Expediting Dry Powder Inhaler Formulation Development Through Modelling and Advanced Characterization

Life Sciences, Pharmaceutical, Pharma Manufacturing & Supply Chain, Drug Discovery & Development,
  • Tuesday, December 04, 2018

Dry powder inhalers are gaining increasing momentum for drug delivery to the lungs. One of the most used and flexible delivery technologies are capsule-based dry powder inhalers.

The successful development of a dry powder inhaler formulation is strongly influenced by the choice of excipient and the ratios between the excipient and active pharmaceutical ingredient (API). The rheological behavior of the powder mixture and its microstructure have a significant impact on several aspects of the final product, such as content uniformity and stability of the formulation, overall aerodynamic performance, deposition patterns and also on the robustness and effectiveness of the capsule filling process.

The present webinar focuses on development by design strategies for dry powder inhalation products. Critical development parameters for an integrated design space analysis will be discussed, showing the compromise between different parameters of performance and downstream process. Moreover, the incorporation of novel characterization strategies such as dissolution and microstructure analysis will be explored.


Beatriz Fernandes, PhD, Scientist DPD, Hovione

Beatriz Fernandes joined the R&D Drug Product Development group at Hovione in 2018 where she has been working on particle design and formulation development projects, with particular focus on the area of inhalation drug products.

Beatriz has an academic background in biological engineering, holding a Master’s degree in Biological Engineering from University of Lisbon, Instituto Superior Técnico. Currently, she is finishing an Industrial PhD in Pharmaceutical Technology in a joint collaboration between the Faculty of Pharmacy from University of Lisbon and Hovione SA. Her PhD thesis is focused on the development of in vitro dissolution techniques for evaluation of inhalation products.

Her research also embraced the investigation of advanced characterization techniques applied for the development of inhalable particles.
