Mechanism of action

Remifentanil activates mu opioid receptors, which inhibit pain signal transmission and modulate consciousness. It is an ester-based opioid that is rapidly metabolized by non-specific plasma and tissue esterases, resulting in a very short half-life (approximately 10–20 minutes) and rapid offset of action, making it ideal for intraoperative and acute care settings.
