Medications used to treat glaucoma include beta-blockers such as Betimol and Betagan, adrenergic agonists such as Propine, prostaglandin analogs such as Travatan and hyperosmotics such as Osmitrol, states WebMD. These medications reduce the amount of fluid that eyes produce or increase the amount of fluid draining from the eyes.
Eye damage from glaucoma is irreversible, but medications can slow or prevent vision loss, says Mayo Clinic. The medicines lower the pressure inside the eye and come in pill, eyedrop or liquid forms, notes WebMD. Patients should use glaucoma medicines as directed and tell their doctors about any noticeable side effects or other prescription medicines they are using.
