Description and Clinical Pharamacology
NovoLog® binds to the insulin receptors on muscle and fat cells. It lowers blood glucose by facilitating the cellular uptake of glucose and simultaneously inhibiting the output of glucose from the liver.
Structural formula of insulin aspart
NovoLog® is produced by rDNA technology
NovoLog® is structurally similar to regular human insulin, with the exception of a single substitution of the amino acid proline by aspartic acid. It is produced by recombinant DNA technology using Saccharomyces cerevisiae (baker's yeast) as the production organism.
One unit of NovoLog® has the same glucose-lowering effect as one unit of regular human insulin. However, NovoLog® is different from regular human insulin in that:
- It has a more rapid onset after subcutaneous injection
- It has a shorter duration after subcutaneous injection
- The single substitution of the amino acid proline with aspartic acid reduces the tendency to form hexamers
Differences in pharmacokinetics and pharmacodynamics between NovoLog® and regular human insulin are not associated with differences in overall glycemic control.
