“…Several classes of approved drugs have been studied through the years for their antioxidant properties [ 1 , 5 , 6 ]. Proton pump inhibitors [ 7 ], antidiabetics [ 8 ], drugs acting on the cardiovascular system [ 9 ], antiepileptics [ 10 ], and anti-inflammatory agents [ 11 ] represent some of the investigated classes, which are also paired by antioxidant natural and semi-synthetic compounds with biological activity [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Furthermore, besides therapeutic agents, it must be stressed that bioactive components from diet have been recognized among the risk factors or, on the other hand, protective agents possibly influencing oxidative stress and pathogenesis of related diseases [ 20 , 21 ].…”
