Acetylcholinesterase inhibitors, including Neostigmine, have been used to reverse neuromuscular blockage for many years. Sugammadex reverses this blockage using its gamma cyclodextrin ring, a mechanism that differs from that of cholinesterases and so circumvents the side effects of Neostigmine. Although the superiority of Sugammadex to Neostigmine has been outlined in several clinical studies, to our knowledge, there is not any research into cell culture that compares the cytotoxic, genotoxic and apoptotic effects of the two drugs...
