Mechanism of action

Insulin glargine is a recombinant human insulin analog with an extended duration of action due to its formulation and pharmacokinetic properties. The U300 formulation (300 units/mL) provides a higher concentration, allowing for smaller injection volumes while maintaining steady basal insulin levels for approximately 24 hours or longer. It works by mimicking endogenous insulin to regulate glucose metabolism and maintain euglycemia in diabetic patients.
