Objective: To prove equivalence of individual, clinically titrated basal insulin doses of glargine 300 units ⋅ mL (Gla-300) and degludec 100 units ⋅ mL (Deg-100) under steady state conditions in a single-blind, randomized, crossover study, on the glucose pharmacodynamics (PD) in people with type 1 diabetes (T1D).

Research Design And Methods: Subjects with T1D ( = 22, 11 men, age 44.3 ± 12.

The aim of this study was to establish the effects of clinical doses of Gla-300 versus Gla-100 on suppression of glucagon, lipolysis, and ketogenesis in type 1 diabetes mellitus (T1DM). Eighteen persons with T1DM (age 40 ± 12 years, diabetes duration 26 ± 12 years, body mass index 23.4 ± 2 kg/m, A1C 7.

Objective: This study characterized the pharmacokinetics (PK), pharmacodynamics (PD), and endogenous (hepatic) glucose production (EGP) of clinical doses of glargine U300 (Gla-300) and glargine U100 (Gla-100) under steady-state (SS) conditions in type 1 diabetes mellitus (T1DM).

Research Design And Methods: T1DM subjects ( = 18, age 40 ± 12 years, T1DM duration 26 ± 12 years, BMI 23.4 ± 2 kg/m, A1C 7.

Objective: Crystalline NPH insulin comes in a two-phase solution with either a solvent or a rapid-acting insulin (in premixed formulations) and needs adequate mixing for complete resuspension before injection. The aim of this study was to establish pharmacokinetics (PK) and pharmacodynamics (PD) after injection of appropriately resuspended versus nonresuspended NPH insulin.

Research Design And Methods: PK and PD were assessed after subcutaneous injection of NPH insulin 0.

Objective: To compare pharmacokinetics (PK) and pharmacodynamics (PD) of insulin glargine in type 2 diabetes mellitus (T2DM) after evening versus morning administration.

Research Design And Methods: Ten T2DM insulin-treated persons were studied during 24-h euglycemic glucose clamp, after glargine injection (0.4 units/kg s.

Objective: To investigate concentration of plasma insulin glargine after its subcutaneous dosing compared with concentration of its metabolites 1 (M1) and 2 (M2) in subjects with type 2 diabetes.

Research Design And Methods: Nine subjects underwent a 32-h euglycemic glucose clamp study (0.4 units/kg glargine after 1 week of daily glargine administration).

Objective: To assess the role of adiposity on the pharmacodynamics of basal insulins NPH, detemir, and glargine in type 2 diabetes mellitus (T2DM), as estimated by glucose infusion rate (GIR) and endogenous glucose production (EGP) rate in the euglycemic clamp.

Research Design And Methods: We examined the variables that best predicted GIR and EGP in 32-h clamp studies after treatment with subcutaneous injection of 0.4 units/kg NPH, detemir, and glargine in 18 T2DM subjects (crossover).

Objective: To compare the pharmacokinetics and pharmacodynamics of NPH, glargine, and detemir insulins in type 2 diabetic subjects.

Research Design And Methods: This study used a single-blind, three-way, cross-over design. A total of 18 type 2 diabetic subjects underwent a euglycemic clamp for 32 h after a subcutaneous injection of 0.

Objective: The objective of the study was to compare responses of plasma levels of IGF-I and IGF binding proteins (IGFBP-1 and IGFBP-3) induced by human regular insulin (HI) and the long-acting insulin analog detemir (IDet) at doses equivalent with respect to the glucose-lowering effect.

Experimental Design: Ten nondiabetic subjects (six males, four females; age, 36 +/- 7 yr; body mass index, 22.9 +/- 2.

Objective: Experimental data from animal studies indicate that portal vein glucose sensors play a key role in the responses to slow-fall hypoglycemia. However, their role in modulating these responses in humans is not well understood. The aim of the present study was to examine in humans the potential role of portal vein glucose sensors in physiological responses to insulin-induced hypoglycemia mimicking the slow fall of insulin-treated diabetic subjects.

Objective: Amino acids stimulate glucagon responses to hypoglycemia and may be utilized by the brain. The aim of this study was to assess the responses to hypoglycemia in nondiabetic and type 1 diabetic subjects after ingestion of an amino acid mixture.

Research Design And Methods: Ten nondiabetic and 10 diabetic type 1 subjects were studied on three different occasions during intravenous insulin (2 mU .

Objective: The acylated long-acting insulin analog detemir is more lipophilic than human insulin and likely crosses the blood-to-brain barrier more easily than does human insulin. The aim of these studies was to assess the brain/hypothalamus responses to euglycemia and hypoglycemia in humans during intravenous infusion of equipotent doses of detemir and human insulin.

Research Design And Methods: Ten normal, nondiabetic subjects (six men, age 36+/-7 years, and BMI 22.
