Key differences
Lasix belongs to Diuretics while Lumigan belongs to Eye Care and Ophthalmic Treatments. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Lasix: Lasix acts in the kidney's loop of Henle, where it blocks the NKCC2 co-transporter that normally reabsorbs sodium, chloride and potassium from the urine back into the bloodstream. Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure.
When Lasix is preferred
Lasix is approved for fluid overload due to heart failure, chronic kidney disease and liver cirrhosis (with or without ascites), as well as acute pulmonary oedema.
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.
