Mechanism and action
Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese. 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.
