International Pharmaceutical Aerosol Consortium on Regulation & Science

The International Pharmaceutical Aerosol Consortium on Regulation & Science (IPAC-RS) is an international association that seeks to advance the science, and especially the regulatory science, of orally inhaled and nasal drug products (OINDPs) by collecting and analyzing data, and conducting joint research and development projects. Representing the OINDP industry since 2000, IPAC-RS aims to build consensus and contribute to effective regulations and standards by sharing the results of its research through conferences, technical journals, webinars, and discussions with regulatory bodies.

IPAC-RS Roundtable Webinar Series 2024

In 2021, IPAC-RS launched a new webinar series.  Presented by SMEs in the pharmaceutical sciences, this opportunity enabled attendees to learn about the latest research and regulatory trends.  See the IPAC-RS Roundtables webpage for links to presentations and recordings for the 5 webinars held in 2021, 2 webinars held in 2022, and 1 webinar held in 2023.


IPAC-RS continues its Roundtable series into 2024, supplementing the podium presentations held at the IPAC-RS/RDD Joint session that addressed Regulatory, Science and Technology Innovations Enabling Novel and Improved OINDP Design, Development and Manufacturing. The first webinar of 2024, Regulatory and Technical Considerations in Sustainable Lifecyle Approaches for OINDP Device and Container Closure Systems (Part III) was held on March 14, 2024.  Visit the Roundtable webpage to view the recording and presentation slides.


Upcoming IPAC-RS Roundtable topics include:

  • Sustainability - Alternate Propellants​
