Key differences

Mechanism and action
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. Xalatan: Latanoprost is a prodrug ester hydrolysed by corneal esterases to its active free acid, which selectively binds the prostaglandin F (FP) receptor.
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).
When Xalatan is preferred
Xalatan is approved in adults and children for the reduction of elevated intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension.
