About Sugammadex

Sugammadex is a novel selective relaxant binding agent (SRBA) underdevelopment by Organon, a part of Schering-Plough Corporation. Sugammadex wasdesigned to reverse the effects of rocuronium bromide or vecuronium bromide,muscle relaxants commonly used during surgeries that require profound musclerelaxation. Anesthesiologists use muscle relaxation to improve surgicalconditions, to facilitate intubation and mechanical ventilation, and to reducethe chance of complications.

In clinical trials to date, sugammadex has demonstrated the ability torapidly reverse shallow and profound depths of rocuronium-inducedneuromuscular blockade (NMB), thereby enabling control of the onset and offsetof skeletal muscle relaxation through the use of both drugs. Sugammadex alsohas demonstrated the ability to reverse the effects of NMB induced byvecuronium bromide. In a phase III clinical trial, the most frequentlyreported adverse events associated with sugammadex regardless of relationshipto the study drug were procedural pain and nausea.


ESLAX (rocuronium bromide), marketed in the U.S. as ZEMURON, is a non-depolarizing muscle relaxant. It was introduced in the United States in 1994and is one of the most widely used muscle relaxants in the United States,Canada and many European countries (where it is marketed under the brand nameESMERON(R)). It was approved for use in Japan on July 31, 2007, under thebrand name ESLAX. To date, it has been used in over 140 million patientsworldwide, including an estimated 20 million patients in 2006.
