About INTO

Who we are, where we come from and what we do

INTO (Inhalation Together)

An alliance of three companies driven by expertise, knowledge,
and decades of inhalation industry experience.

As long-standing industry partners, the shifting tides of innovation and the growing importance of speed to market, combined with the complexities of inhaled formulation, encouraged us to unite our strengths and capabilities. Hence, a compelling conclusion arised: collaboration and synergy as key to success, providing a scientific and holistic solution-oriented approach to inhaled formulation development for small and large molecules.

In February 2022, the signing of an agreement marked INTO’s official journey, solidifying the commitment of all three companies involved — DFE Pharma GmbH & Co.KG, Harro Höfliger GmbH, and Sterling S.p.A. One shared vision, commitment to excellence, and the determination to accelerate DPI development is what unites us in the journey to come.

As we continue, we’re proud and excited about the possibilities ahead. INTO is more than just an alliance; it’s a shared passion of shaping the future of inhaled therapies.
