Pressurized metered dose inhalers (pMDIs) are complex products, especially when compared with standard dosage forms such as oral tablets or injectable formulations. At their core, they consist of the drug formulation (solution or a suspension) combined with propellants and excipients in a pressurized canister. The can is seated into an actuator and connected to a valve which delivers the formulation. The delivery method is extremely attractive due to the direct delivery to the target site, rapid onset of action, high and long-term pulmonary efficacy, reduced risk of systemic side effects and has been accepted by patients across the world mainly for its portability.

The FDA has classified pMDI’s as a combination product due its uniqueness of drug device combination. Genericizing a pMDI’s has been a major challenge especially for the US market where the regulatory hurdles make it even more difficult for the generic companies to achieve approval. Although this past year, we have seen several new key approvals that seem to be paving the way for others. Also, the present Covid 19 situation has led to a number of generic pMDIdi’s having their approvals fast tracked by the FDA and other regulators around the world which could lead to quicker approvals of pMDI applications in the future. in order to have more metered dose inhaler supplies available to treat respiratory disease.

In this webinar H&T Presspart and Proveris will focus on two important arms of the pMDI system; namely the canister and the actuator with built in dose counter indicator. H&T Presspart will highlight key learnings in the areas of design, development, manufacturing of generic pMDI products while Proveris will focus on analytical tools (specifically the SprayVIEW® Measurement System) and applying the technology to accelerate development from early R&D stages straight through to manufacturing QC.

Ameet Sule will present the suitability of the plasma treated canister and the development process of a generic actuator with a dose counter. Ian Flaherty will continue on presenting the use of the SprayVIEW Measurement System and the use of spray pattern and plume geometry measurements combined with the importance of employing automated shaking and actuation in testing to achieve a suitable device design for generic products. Please join us on October 27th to learn strategies geared towards ensuring the timely success of your pMDI development projects.
