Lantus is a long acting insulin which has been synthesized in the laboratory by altering the structure of human insulin. It is a man-made insulin and is therefore not found naturally in the body unlike human insulin. The altered structure gives it special chemical properties which enable it to last for 24 hours. It has no 'peak' to it's action curve and is therefore a true 'basal' insulin.
Lantus is available in vials, cartridges for use in OptiPen devices or as disposable pens.
Vials contain 10 ml which contain 1000 units (100 units/ml)
Cartridges contain 3 ml of Glargine which contain 300 units (100 units/ml). these cartridges are available in packs of five.
Prefilled pens (Lantus OptiSet) also contain 300 units (100 units/ml). These pens are sealed disposable devices and are available in packs of five.
Lantus OptiPen Pro is a pen which takes replaceable cartridges of 300 units (3ml) each.
Lantus OptiSet pens are pre-filled disposable pens. You may dial up doses in increments of 2 units up to a maximum of 40 units as a single dose. The pens do not require shaking or mixing before use.
Lantus is used once daily and usually injected in the evening.
