Prozac 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.

Mechanism and action
Prozac: Fluoxetin hemmt selektiv den Serotonin-Wiederaufnahmetransporter und erhöht so die synaptische Serotoninverfügbarkeit. Ativan: Lorazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chloridleitfähigkeit.
