We included diabetes type 1 (T1DM) patients with suboptimal glycemic control on morning application glargine (I-Glar) U100, switching them to U300. After six months improvement in HbA1c was observed, while hypoglycemic episodes decreased. Switch from I-Glar U100 to U300 could be a good therapeutic option for that subset of patients.
Keywords: Glargine U100; Glargine U300; Glycemic control; Hypoglycemia; T1DM.
