Mechanism and action
Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure. Demadex: Torsemide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, producing potent natriuresis and diuresis.
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.
When Demadex is preferred
Demadex is approved for oedema in heart failure, hepatic cirrhosis or chronic kidney disease, and for hypertension at low doses.
