Disposable Dosators for Pulmonary Insufflation of Therapeutic Agents to Small Animals. | LitMetric

AI Article Synopsis

  • Developing new therapeutic products involves testing their effectiveness using animal models, often through inhalation methods for delivering drugs.
  • To evaluate dry powder aerosols, an efficient dispersion mechanism is crucial for maintaining drug concentrations for animal exposure.
  • Our team has created a new dispersion system (dosator) that efficiently aerosolizes engineered dry powders, improving the delivery for pulmonary administration and analytical applications.

Article Abstract

Development of new therapeutic products requires efficacy testing in an animal model. The pulmonary route of administration can be utilized to deliver drugs locally and systemically. Evaluation of dry powder aerosols necessitates an efficient dispersion mechanism to maintain high concentrations in an exposure chamber or for direct endotracheal administration. While solutions exist to expose animals by passive inhalation to dry powder aerosols, most require masses of powder in large excess of the dose delivered. This precludes conducting early feasibility studies as insufficient drug is available at the research or early development stage to support the dose delivery requirements for conventional aerosol delivery systems. When designing an aerosol drug product, aerodynamic performance can relate directly to delivery efficiency and efficacy. Dispersion of powder into an aerosol requires energy input sufficient to overcome interparticulate forces, and particle engineering approaches can substantially improve aerosol performance. We have developed a dispersion system (dosator) which can aerosolize engineered dry powder aerosols efficiently for the purpose of direct pulmonary insufflation, dispersion into an exposure system or generation for analytical purposes.
