Remifentanil (marketed by Abbott as Ultiva) is a potent ultra short-acting synthetic opioid analgesic drug. It is given to patients during surgery to relieve pain and as an adjunct to an anaesthetic. ULTIVA is a µ-opioid agonist with rapid onset and peak effect, and short duration of action. The µ-opioid activity of ULTIVA is antagonized by opioid antagonists such as naloxone. ULTIVA is indicated for IV administration: 1. As an analgesic agent for use during the induction and maintenance of general anesthesia for inpatient and outpatient procedures. 2. For continuation as an analgesic into the immediate postoperative period in adult patients under the direct supervision of an anesthesia practitioner in a postoperative anesthesia care unit or intensive care setting. 3. As an analgesic component of monitored anesthesia care in adult patients.

In Vivo Use Guide

Usual Adult Dose for Anesthesia Induction of Anesthesia: Continuous IV infusion: 0.5 to 1 mcg/kg/min. If endotracheal intubation is to occur in less than 8 minutes, an initial dose of 1 mcg/kg may be administered over 30 to 60 seconds. Maintenance of Anesthesia: With Nitrous Oxide, 0.4 mg/kg/min by continuous IV infusion. Infusion dose range: 0.1 to 2 mcg/kg/min. Supplemental IV bolus: 1 mcg/kg every 2 to 5 minutes.

Route of Administration: Intravenous
