A review of preserved and preservative-free prostaglandin analogues for the treatment of open-angle glaucoma and ocular hypertension.
Glaucoma affects an increasing number of people worldwide and is the second leading cause of blindness. The aim of antiglaucoma therapy is to maintain a patient's visual function and quality of life. Prostaglandin analogues are first-line topical antiglaucoma therapy. They are effective at lowering intraocular pressure (IOP) and are generally well tolerated, with fewer systemic adverse events compared with the other classes. However, the use of prostaglandin analogues can be associated with ocular adverse effects, such as stinging/burning sensation, dry eyes, iris and periocular hyperpigmentation, and eye lash growth, which can affect patient compliance. Preservatives used in antiglaucoma preparations can have dose-dependent toxic effects, which contribute to adverse effects. The development of preservative-free preparations may reduce such adverse effects and therefore improve patient compliance. Tafluprost is a prostaglandin analogue in a preservative-free formulation that was recently approved for the reduction of elevated IOP in open-angle glaucoma and ocular hypertension.
