Insulin glargine U300 (Toujeo®) is a new formulation based on the insulin glargine molecule, but with a reduced redissolution rate following subcutaneous administration, resulting in a flatter and more prolonged pharmacokinetic/dynamic profile than Lantus®. According to the UKMi New Drugs Online database, insulin glargine U300 is likely to be launched around the same time that Lantus® loses patent protection in late 2014.
