Mechanism and action
Doxycycline: Doxycyclin bindet reversibel an die 30S-Untereinheit bakterieller Ribosomen, verhindert die Bindung von Aminoacyl-tRNA und hemmt damit die Proteinsynthese. Zoloft: Sertralin wirkt durch selektive Blockade des Serotonintransporters und verhindert so die Wiederaufnahme von Serotonin aus dem synaptischen Spalt, wodurch die synaptische Serotoninkonzentration erhöht wird.
