Cisatracurium is a medication used as a neuromuscular blocker during surgical procedures. It works by blocking the transmission of nerve impulses to the muscles, leading to temporary paralysis. This allows for easier intubation and muscle relaxation during surgery. Cisatracurium is often preferred in patients with liver or kidney issues because it is broken down in the body by a process called Hofmann elimination and by non-specific plasma esterases. This makes it a safer option for those with compromised organ function, ensuring effective muscle relaxation without prolonged effects.
