Mechanism and action
Spironolactone: La spironolactone bloque de façon compétitive le récepteur de l'aldostérone (minéralocorticoïde) au niveau du tube distal, réduisant la réabsorption du sodium et l'excrétion du potassium. Ativan: Le lorazépam se lie au site benzodiazépine du récepteur GABA-A et renforce de façon allostérique la conductance chlorure inhibitrice.
