What is afrezza’s nonproprietary (generic) name?

Afrezza’s brand name corresponds to the nonproprietary (generic) name insulin human (inhaled insulin) [1].

Why does the nonproprietary name look different from typical generics?

Afrezza is a formulation of insulin used by inhalation rather than the more common injectable insulin products, so its nonproprietary naming reflects the active ingredient rather than a distinct “-pril” or “-mab” style generic name [1].
