In Vitro Timolol (hemihydrate) can significantly prevent the increased lipid peroxidation level of the heart from diabetic rats. Timolol (hemihydrate) 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 (hemihydrate) (5 mg/kg daily for 12-week) has a cardioprotective effect via inhibition of ERS response in diabetic rats[3]. Animal Model: Male Wistar rats[3]. Dosage: 5 mg/kg Administration: Timolol (5 mg/kg daily for 12-week) Result: Showed cardioprotective effect.
