Key differences
Lumigan belongs to Eye Care and Ophthalmic Treatments while Singulair belongs to Respiratory Medications. 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
Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure. Singulair: Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils.
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 Singulair is preferred
Singulair is approved in adults and children for the maintenance treatment of asthma, including exercise-induced bronchospasm, and for the treatment of seasonal and perennial allergic rhinitis when conventional therapy is insufficient or not tolerated.
