On 28th June 2023, the first conference dedicated to soft mist inhalers took place in London, U.K. Its purpose was to enable delegates to learn to make, use and launch soft mist inhalers.

Speaker's Slides


SMI.London 2023 illustrated how SMIs are taking their place alongside other inhalers, what benefits their bring. The day explored the regulatory and scientific context in which SMIs are developed. It charted the path from molecules to finished dosage forms. The event included talks on SMI device technology, regulatory and practical aspects of formulating and testing SMIs, aspects of leachables and extractable science for SMIs, and human factor studies. The speakers at SMI.London 2023 were key opinion leaders with extensive experience in the field of Inhaled Drug Delivery.

SMIs are inhalers with one of the lowest carbon footprints. They have the potential to capture 50% of the portable inhaler market alongside DPIs.
