Mechanism and action
Ativan: Lorazepam bindet an die Benzodiazepin-Bindungsstelle des GABA-A-Rezeptors und verstärkt allosterisch die hemmende Chloridleitfähigkeit. Pepcid: Famotidin blockiert reversibel und kompetitiv die Histamin-H2-Rezeptoren an den Belegzellen des Magens und vermindert sowohl die basale als auch die stimulierte Magensäuresekretion.
