Understanding Afrezza: Mechanism, Farmakokinetyka, and Clinical Role

How Afrezza Works

Afrezza (insulin human) inhaltation powder is a rapid- acting insulin deliveid through a breathing-powildd inhalter. Unlike injectable insulins that the blootream via subcutanous tissue, Afrezza relies on absorption across the large surface area of thee alveolar epiblicutaim. Once inhalled, thee insulin particles deposit in thee deep lungs and are quiclly translocated into systemic ciation.
