Timolol hemimaleate  (Synonyms: (S)-L-714,465 hemimaleate; MK 950 hemimaleate)

Timolol ((S)-L-714,465; MK 950) hemimaleate is a β-blocker available for both topical and systemic administration. Topical Timolol hemimaleate is primarily used to reduce intraocular pressure with open-angle glaucoma and ocular hypertension. Timolol hemimaleate 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].

Timolol hemimaleate can significantly prevent the increased lipid peroxidation level of the heart from diabetic rats. Timolol hemimaleate 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].
