Mechanisms compared
Buspar: Buspirone is a partial agonist at the serotonin 5-HT1A receptor and a weak antagonist at dopamine D2 receptors. Amiloride: Amiloride blocks the epithelial sodium channel (ENaC) in the distal convoluted tubule and collecting duct of the kidney, reducing sodium reabsorption and indirectly decreasing potassium and hydrogen ion excretion.
