LANTUS® must NOT be diluted or mixed with any other insulin or solution.

DRUG DESCRIPTION

Insulin glargine is a recombinant human insulin analog that is a long-acting (up to 24-hour duration of action), parenteral blood-glucose-lowering agent. (See CLINICAL PHARMACOLOGY). LANTUS (insulin glargine rdna origin injection) is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12) as the production organism.

Chemically, it is 21A- Gly-30Ba-L-Arg-30Bb-L-Arg-human insulin and has the empirical formula C267H404N72O78S6 and a molecular weight of 6063. It has the following structural formula:
