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. Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen.
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 Voltaren is preferred
Voltaren is approved in adults for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute musculoskeletal pain, post-surgical pain, primary dysmenorrhoea, acute migraine and ureteric colic.
