Dry Powder Inhalers (DPI)

Abstract Objectives The aim of the project was to develop and characterise powders containing a probiotic (Lactiplantibacillus plantarum , Lacticaseibacillus rhamnosus, or Lactobacillus acidophilus) to be administered to the lung for the containment of pathogen growth in patients with lung…

Abstract Although the amount of amorphous content in lactose is low, its impact on the performance of a dry powder inhalation formulation might be high. Many formulators and regulatory agencies believe that the levels of amorphous content should be controlled once there is a relationship with the…

In an ideal world, pharmaceutical drugs would have infinite shelf life, no susceptibility to degradation, chemical reactions or loss of efficacy. In reality, these processes occur, however, making it desirable to extend a drugs’ shelf life. Nucleic acid-based drugs are most commonly stored as…
