International Pharmaceutical Aerosol Consortium on Regulation & Science
The International Pharmaceutical Aerosol Consortium on Regulation & Science (IPAC-RS) is an international non-profit association comprised of companies that develop, manufacture, market, and support research and development of inhaled and nasal drugs and biologics (INDBs). IPAC-RS seeks to advance the science, and especially the regulatory science, of these products by collecting and analyzing data, conducting joint research and development projects, and engaging the wider community. Representing this industry sector for more than 25 years, 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.
