Atracurium 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. Atracurium is often preferred in patients with liver or kidney issues because it is broken down in the body through a process called Hofmann elimination and non-specific plasma esterases. Its effects can be reversed with specific medications, making it a useful option in anesthesia practice.
