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. Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure.
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 Lumigan is preferred
Lumigan is approved in adults for the reduction of elevated intraocular pressure in patients with chronic open-angle glaucoma or ocular hypertension.
