Mechanism and action
Toprol XL: Le métoprolol bloque sélectivement les récepteurs bêta-1 adrénergiques cardiaques, réduisant la fréquence cardiaque, la contractilité et la vitesse de conduction auriculo-ventriculaire, et abaissant la consommation myoca… Klonopin: Le clonazépam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure inhibitrice, hyperpolarisant les neurones du système nerveux central.
