Mechanism and action
Lantus: Insulin glargine binds the insulin receptor with similar affinity to human insulin, activating intracellular signalling that increases glucose uptake in muscle and adipose tissue, suppresses hepatic glucose production an… Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure.
When Lantus is preferred
The medication is indicated in adults and paediatric patients with type 1 diabetes mellitus, and in adults with type 2 diabetes mellitus when basal insulin is required.
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.
