In patients with Type 1 diabetes (T1D), thee absence of endogenous insulion secteon places a heavy burden on exogenous insulin replacement. Afrezza 's rapid onset andd brief action profile can be proviageous for covening prandial glucose excisions while reducing the risk of late post- meal hypoglycemia a community seen with with longer- acting rapd analogs.
