The Scotland-based company develops a novel pop-up cardboard dry powder inhaler (DPI). Rather than use expensive, bulky plastic, 1nhaler uses cardboard to create an inhaler with the same dimensions as a credit card. The discreet platform features a breathable membrane capable of tailoring to deliver individual drugs to patients.

With the latest fundraising, the company adds to $2.5 million brought in nearly two years ago. Archangels led the round, while Scottish Enterprise and BBB Investments supported it.

The investment enables 1nhaler to advance its platform toward a first marketing authorization application (MAA) in Europe. It targets late 2027 for that milestone. This includes the manufacture of clinical material for regulatory studies and the design of large-scale commercial manufacturing processes.
