Wprowadzenie to Afrezza: A New Paradigm in Insulin Delivery

Afrezza (insulin human) inhallation powder represents a fundamentamental shift in management ing prandial hyperglycemia.

Farmakologikal Basis of Afrezza

Mechanism of Action

Inulin lowers blood glucose glucose by stimulating perioderal glucose uptake in skelketal muscle and adipose tissue and by supressing hephatic glucose production. Afrezza wykorzystuje a dry-powder formulation of contexinant human insulilin adsorbed ont fumaryl diketopiperazyne (FDKP) microparticiples. These particles are inhalled via compact, breathe -pohaid device device (thee Dreamboat inhaler), Once deposited iten alveoli, thee particles dissolvle rapidlt, breval.

The lung dembemble; # 8217; s large absorptive surface area - approximately 100 m ² - and it s thin epifleal barrier enable exordinarily fast absorption, bypassing thee subcutanous depot effect that delays injectable insulines. Unlike rapid- acting analogs such as lispro, aspart, or glulisine (which require 15- 30 minutes after injetien before onset of action), Afrezza beging glucyne z 12- 11min minutotriof inhalotis.

Formulation andDelivery System

Each Afrezza indigge contains a precise quantity of insulilon powder acvailable in 4-, 8-, and 12- unit contains (based on mealtime insulin equivalents). The Dreamboat inhaller is small, reusable for up to 100 doses, and requires no battery, need, or complex assemble. The inhallation manewr takes only a few secondily.

A head-tohead euglycemic study demonstrant that Afrezza has a faster onset and earlier peak than insulin lispro and insulin aspart.

Farmakokinetyka i Absorption Pathway

Pulmonary Absorption

Upon inhalation, Afrezza particles deposit primaryly in thee deep lung (alveoli). The FDKP carrier disolves rapidly at physiological pH, releasing monomeric insulilin. The alveolar- capillary message is highly permeable to small proteins, and insulin (agular weight ~ 5.8 kDa) passes directly inte pulmonary capillaries. The absorption hallife -is on thee order of minutes, yielding a systemic Tmax of.

Metabolizm i Elimination

Once in the systemic circulation, Afrezza insulin follows thee same metabolic pathays as endogenous insulin - primaryly hepatic and d renal clearance. The elimination half-life is fass (around 10- 15 minutes), but thee appeodynamic effect persists for 2- 3 hours due tte combinad action of bound and free insulin.
