BimatoprostA Pharmacoeconomic Review of its Use in Open-Angle Glaucoma and Ocular Hypertension

Bimatoprost (Lumigan®) is a prostamide analogue used for the reduction of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. In comparative clinical trials of up to 1 year in duration, administration of 0.03% bimatoprost ophthalmic solution once daily was more effective than 0.5% timolol twice daily and at least as effective as the prostaglandin analogues 0.005% latanoprost and 0.004% travoprost once daily in terms of reducing IOP and/or achieving target IOP levels. Bimatoprost was also more effective than twice-daily administration of 0.5%/2% timolol/dorzolamide in patients refractory to topical timolol therapy. Although generally well tolerated, bimatoprost is associated with a higher incidence of conjunctival hyperaemia than latanoprost, timolol or the combination of timolol and dorzolamide.
