Ann Flodin introduces the company’s SprayVIEW® measurement and automated actuation stations for the development and quality control of container closures and finished products.
SPRAYVIEW® MEASURING SYSTEMS BY PROVERIS
Recipharm has the expertise and specialised equipment to support the development of quality analytical techniques for the development of inhaled products, specifically nasal and oral sprays, and pressurised metered-dose inhalers (pMDIs). This includes the company’s SprayVIEW® measurement and automated actuation stations, developed by Recipharm’s expert development team. SprayVIEW® is a registered trademark of Proveris Scientific.
Inhalation products are extremely complex to develop and manufacture, and it is important to understand potential interactions between the formulation and the delivery device throughout the development stages.
Spray pattern and plume geometry are critical attributes when characterising nasal and oral sprays and pMDI aerosols, and are critical for conducting accurate and consistent spray pattern and plume geometry tests (Figure 1).
The acquisition of real-time images of aerosols or sprays emitted from a device, using a high-speed camera, enables subsequent analysis of the spray pattern and plume geometry, which represents the shape of the aerosol or spray. Recipharm’s automated MDx and NSx actuation stations allow for consistent actuation using parameters such as actuation velocity and acceleration, minimising intra- and inter-device variability. The NSx and MDx are automated test stations for actuating nasal spray products and pMDIs, respectively.
Actuation graphs, derived from data collected during spray pattern and plume geometry measurements, display the actuation profile to determine the force-to-actuate profile of the device.
SprayVIEW® measurement systems are not only valuable tools to guide drug product development, but can also be used to support quality control for container closure components (i.e. valves, pumps) and finished drug products.
As part of Recipharm’s spray pattern and plume geometry test service, the company offers inhalation and nasal spray product development from initial formulation and process development to registration, commercial batch release and product characterisation. Recipharm carries out in vitro bioequivalence (IVBE) studies in generic inhalation and nasal spray product development, and uses its expertise to develop and validate SprayVIEW®-based methods for aerosol and nasal spray testing. The company also provides support with device-related changes during the product lifecycle (Figure 2).
