Mounjaro: Tirzepatide binds with high affinity to both the GIP and the GLP-1 receptors. Midamor: 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.

When Midamor is preferred
Midamor is approved for hypertension (typically in combination with thiazides), oedema in heart failure or hepatic cirrhosis (in combination), and primary hyperaldosteronism (Liddle syndrome and pseudohyperaldosteronism).
