Lantus and Ativan are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.

Key differences

Lantus belongs to Behandlung der Diabetes mellitus while Ativan belongs to Angstlösende Medikamente. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.

Mechanism and action

Lantus: Insulin Glargin bindet mit ähnlicher Affinität wie Humaninsulin an den Insulinrezeptor und aktiviert intrazelluläre Signalwege, die die Glukoseaufnahme in Muskel- und Fettgewebe steigern, die hepatische Glukoseproduktion… Ativan: Lorazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chloridleitfähigkeit.

When Lantus is preferred

Das Arzneimittel ist bei Erwachsenen und pädiatrischen Patienten mit Diabetes mellitus Typ 1 sowie bei Erwachsenen mit Diabetes mellitus Typ 2 indiziert, wenn ein Basalinsulin erforderlich ist.

When Ativan is preferred

Ativan ist bei Erwachsenen zur Kurzzeitbehandlung von Angststörungen und angstbedingten Schlafstörungen zugelassen.
