Timolol is a medication that is commonly used to lower eye pressure in individuals with glaucoma. It works by reducing the amount of fluid in the eye, which in turn reduces the pressure. There are several synonyms for the word timolol, including timoptic, blocadren, and betimol. These medications are all beta-blockers, which means they work by blocking certain receptors in the body to achieve their desired effect. While timolol is the most commonly prescribed medication for glaucoma, these other medications may be used if a patient experiences side effects or is unable to tolerate timolol. It is important to consult with a healthcare provider before starting any new medication.
