Pii provides formulation and manufacturing services for dry powder inhalers (DPIs), pressurized metered dose inhalers (pMDIs) and intransal products. Our specialization covers both small molecules (such as inhaled corticosteroids, beta agonists etc) and macromolecules (such as antibodies, vaccines etc).

To support your drug development, we offer a range of services to help you reach clinical trials and ultimately product launch in the quickest and most cost effective way. Whatever your respiratory drug delivery needs Pii has the expertise and experience to support you. Our inhaled drug delivery services include:

  • Early stage pre-formulation support
  • Candidate drug selection support
  • Inhalation particle design and engineering
  • Material characterization and sourcing
  • Drug-excipient compatibility testing
  • Formulation development of inhalation and intranasal drug products
  • Manufacturing process development and optimization, e.g., particle size reduction process.
  • Inhaler device selection
  • in vitro testing of prototype formulations
  • Stability testing of drug and formulations
  • Cleaning verification development
