Mechanism of Action and Pulmonary Dynamics

How Afrezza Enters the Bloodstream

Afrezza considens of a dry powder formulation of regular human insulilin adsorbed onto Technosfere microparticles (fumaryl diketopiperazine). These particles are approximately 2- 5 micrometers in diameteter, a size commerceret to deposit in thee deep alveolar regions of thee lungs rather than the upper airways.

Absorption, Peak, andDuration

Compred to rapid- acting injectable analogs (such as lispro or aspart), which require 30- 90 minutes too peak, Afrezza reaches maximum serum concentration in 12- 15 minutes and has a shorter duration of action (about 2.5- 3 hours).

Clinical Evedence Base for Afrezza Safety

Short-Term Safety from Pivotal Trials

Te pivotal Phase 3 trials (Affinity 1, 2, and 3) included over 2.500 patients with type 1 andtype 2 diabetes exposed to Afrezza for at least 6 months. The most convers events were cough (approatele 25- 30% of patients), threat pain, and minur wheezing. Most cases of cough were mild ande tended tone resolve with in thee first few weeks therapy. Hipoglycemica rates were doable tor slightly lor.

Spirometry data from these trials showed a small, early decline in forced indecatiatory volume in one second (FEV Colomb) during the first 3 months of use - typically a drop of 40- 80 mL - followed by stabilization.

Patient Populations at Hiper Risk

Afrezza is contraindicated in patients with astma and d chronic obturativa pulmonary disease (COPD) because of te risk of acute bronchospasm and accelegated decline in lung functionion. Even patients with well-controlled astma can experimence a clically signitant drop in FEV experiments. A retrospective analysis of patients with mild astma who initiated Afrezza found average 12% decline in FEV exalin 3 months, comparad to 4% n those with astmn.

Smokers andvapers

Tobacco smoking acutely reduces insulin absorption from lungs - likely due to altered airway geometry andd increaged mucus production - resuctin g in lower and more variable biodostępność of Afrezza.
