Inhaled Drug Delivery - Formulation Development
Pharmaterials provides a contract, fee for service, offering for the formulation of dry powder inhalers (DPIs) and pressurized metered dose inhalers (pMDIs). Our specialization covers both small molecules (such as inhaled corticosteroids, beta agonists etc) and macromolecules (such as antibodies, vaccines etc). Our business also expands to the formulation of intranasal products
Whatever your respiratory drug delivery needs we are happy to provide:
-
early stage pre-formulation support
-
candidate drug selection support
-
design and engineering of particles suitable for inhalation
-
material characterization and sourcing
-
drug-excipient compatibility testing
-
formulation development of inhalation and intranasal drug products
-
development and optimization of manufacturing processes e.g. particle size reduction process
-
selection of an inhaler device.
-
in vitro testing of prototype formulations
-
stability testing of drug and formulations
-
development of cleaning verification processes
-
