Sugammadex sodium is used to reverse the effects of neuromuscular blocking agents, specifically rocuronium and vecuronium, which are used during surgery to relax muscles. It works by encapsulating the blocking agent, rapidly restoring normal muscle function at the end of anesthesia. This allows patients to breathe and move muscles more quickly after surgery, reducing the need for prolonged mechanical ventilation. It offers a faster and more predictable reversal compared to traditional agents like neostigmine, especially in cases requiring deep or prolonged muscle relaxation. Its use improves patient safety and can shorten recovery time in the operating room and post-anesthesia care unit.
