Bivalirudin is a synthetic 20 amino acid peptide rationally designed based on structural studies of hirudin, a naturally occurring anticoagulant. Bivalirudin is sold under the brand name Angiomax and is indicated for use as an anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty (PTCA). It is intended for use with aspirin and has been studied only in patients receiving concomitant aspirin. Bivalirudin directly inhibits thrombin by binding simultaneously to its active catalytic site and its substrate recognition site.

Triptorelin is a synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). It works by decreasing the production of certain hormones, which reduces testosterone levels in the body. Animal studies comparing triptorelin to native GnRH found that triptorelin had 13 fold higher releasing activity for luteinizing hormone, and 21-fold higher releasing activity for follicle-stimulating hormone. Triptorelin is indicated for the palliative treatment of advanced prostate cancer.

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.
