Glargine is a long-acting synthetic insulin used for the treatment of canine diabetes mellitus.

Glargine is a synthetic insulin analogue and is produced using recombinant DNA technology utilizing Escherichia coli.

Glargine has the advantage over protamine zinc insulin in rarely inducing hypoglycemia[1] and can be used as a single-dose once daily drug[2].

Recommended dose rate is 0.25 - 0.5 U/kg as a starting dose[3].

Glargine (Lantus) must not be diluted or mixed as this affects the peak effect[4].
