Afrezza: A Novel Inhaled Insulin - Farmakokinetyka i Klinika Profile

Afrezza (mannitol inhalation spoder) is a rapid- acting inhalled inhalied inhalied approved for difficients wich difficultus. Its unique delivy systeme uses a dry powder formulation inhalted via a compact, breathy- powilid device. Unlike subcutanous insulins that require insertion intro fatty tissue, Afrezza is absorbed directly thriog thee lung epiblicum, reaching peak plasma concentrations with in 12- 15 minutees - faster thaly inservine -acting analog one.

This profile offers distinct clinical providences. Clinical trials comparing Afrezza to insulin aspart and lispro demonstrantate comparable HbA1c reductions (0.4-0.6%) with a lower incidence of nocturnal hypoglycemia. The rapid onset allows patients to dose emplately before eating, improwiing expermibility.
