ABSTRACT
Introduction: A more concentrated insulin glargine formulation, containing 300 U/mL (Gla-300) was approved in 2015 in the US and Europe for the treatment of diabetes mellitus in adults.
Areas covered: This drug evaluation focuses on the pharmacokinetics (PK) and pharmacodynamics (PD) of Gla-300 from studies published up to May 2016. The clinical relevance of this new formulation will be addressed.
Expert opinion: Gla-300 was developed to produce a flatter and more prolonged PK/PD profile compared with insulin glargine 100 U/mL (Gla-100) in order to maintain effective glycemic control and reduce the risk of hypoglycemia. Compared to Gla-100, Gla-300 achieves lower and delayed peak concentrations with a PK exposure that is more stable and evenly distributed across a 24-h dosing interval. As a consequence, Gla-300 results in a consistent glucose-lowering effect with less variability over a 24-h dosing interval, which translates to a reduction in the rate of hypoglycemia (particularly nocturnal events).
