Insulin aspart, a human insulin analogue, is a rapid-acting, parenteral blood glucose-lowering agent. Insulin aspart was marketed under the brand name NovoLog for the treatment of adult patients with diabetes mellitus, for the control of hyperglycemia. The primary activity of the drug is the regulation of glucose metabolism. Insulin aspart binds to the insulin receptors on muscle and fat cells and lower blood glucose by facilitating the cellular uptake of glucose and simultaneously inhibiting the output of glucose from the liver. This drug has an off-label treatment for gestational diabetes (temporary diabetes caused by diabetes).

Insulin glargine, a long-acting form of insulin, was marketed under the brand name LANTUS. Lantus is indicated for the treatment of adult and pediatric patients with type 1 diabetes mellitus or adult patients with type 2 diabetes mellitus who require basal (long-acting) insulin for the control of hyperglycemia. The primary activity of insulin glargine is regulation of glucose metabolism. It lowers blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. The off-label use of insulin glargine is the treatment type 2 diabetes in children and the treatment of gestational diabetes.
