About AFREZZA®

AFREZZA® (uh-FREZZ-uh) is a novel, ultra rapid-acting mealtime insulin therapy developed by MannKind Corporation to improve glycemic control in adult patients with type 1 or type 2 diabetes. It is a drug-device combination product, consisting of AFREZZA Inhalation Powder delivered using a small, discreet and easy-to-use inhaler. Administered at the start of a meal, AFREZZA Inhalation Powder dissolves immediately upon inhalation to the deep lung and delivers insulin quickly to the bloodstream.
