Inhalable insulin is a powdered form of insulin, delivered with an inhaler into the lungs where it is absorbed.[1] In general inhaled insulins have been more rapidly absorbed than subcutaneous injected insulin, with faster peak concentration in serum and more rapid metabolism.[2]
Exubera, developed by Inhale Therapeutics (later named Nektar Therapeutics), became the first inhaled insulin product to be marketed, in 2006 by Pfizer,[3] but poor sales led Pfizer to withdraw it in 2007.[4] Afrezza, a monomeric inhaled, ultra rapid-acting insulin developed by Mannkind, was approved by the FDA in 2014 and is the only inhaled insulin commercialized at the moment.[5]
