Timolol is a β-blocker available for both topical and systemic administration. Topical Timolol is primarily used to reduce intraocular pressure with open-angle glaucoma and ocular hypertension. Timolol can also be used for the research of infantile hemangiomas, hypertension, myocardial infarction, migraine prophylaxis, and atrial fibrillation.Timolol also has cardioprotective effect[1][2].

In Vitro	Timolol can significantly prevent the increased lipid peroxidation level of the heart from diabetic rats. Timolol can induce a well-balanced ratio between oxidative stress and antioxidant defense system in the diabetic animals, can have an important cardioprotection against diabetes-induced ERS and associated apoptotic effects[3].
In Vivo	Timolol has a cardioprotective effect via inhibition of ERS response in diabetic rats[3]. Animal Model: Experimental diabetes model: 3-month old male Wistar rats[3]. Dosage: 5 mg/kg Administration: Timolol (5 mg/kg daily for 12-week) Result: Showed cardioprotective effect.
