商品名：Ultiva
Remifentanil is an ultra-short-acting synthetic mu-opioid receptor agonist. It contains an ester linkage that is rapidly hydrolyzed by nonspecific plasma and tissue esterases, resulting in an extremely short context-sensitive half-time independent of infusion duration. Provides potent analgesia with rapid onset and offset.
Intraoperative analgesia via CRI (constant rate infusion). Used during surgical procedures requiring precisely controllable analgesia.
