REMIFENTANIL C화학적 특성, 용도, 생산
용도
Analgesic.
정의
ChEBI: A piperidinecarboxylate ester that is methyl piperidine-4-carboxylate in which the hydrogen attached to the nitrogen is substituted by a 3-methoxy-3-oxopropyl group and the hydrogen at position 4 is substituted the nitrogen of N-propanoy
aniline.
World Health Organization (WHO)
Remifentanil is defined as an opioid narcotic with an addictionforming
and addiction-sustaining liability similar to morphine.
일반 설명
Remifentanil (Ultiva) was designed as a “soft drug.” Softdrugs are designed to undergo metabolism quickly and thushave ultrashort durations of action. In place of the ethylaromatic ring seen on the other piperidine opioids, remifentanilhas an ester group. This ester group is metabolizedby esterases in the blood and tissue to a weaklyactive metabolite (1:300–1:1,000 the potency of remifentanil). The n-octanol/water partition coefficient ofremifentanil is 17.9. The pKa of remifentanil is 7.07, thus itis predominately unionized at physiological pH. Both ofthese properties account for its rapid distribution across theblood-brain barrier (<1 minute). The ester hydrolysis leadsto a quick recovery (5–10 minutes) independent of durationof drug administration, renal, or liver function. The favorablepharmacodynamics of remifentanil have led to its usefor induction and maintenance of surgical anesthesia.
Pharmacology
Remifentanil is a MOP agonist with a similar potency to fentanyl and
approximately 20 times more than alfentanil. It has a rapid blood–brain
equilibration time of just over 1min, with a short context-sensitive half-life of
3–5min, which is unaffected by duration of infusion. This makes it ideally
suited for infusion during anaesthesia and in critical care. It may be titrated
rapidly to achieve the desired effect. Remifentanil is available as a lyophilised
white crystalline powder containing glycine; it should not be administered
via the epidural or intrathecal routes. There may be increased opioid
sensitivity in hepatic disease, resulting in a lower dosage requirement. Other
situations requiring a reduction in dose include haemorrhage and shock and
when administering in elderly patients. The high clearance and low VD imply
that the offset of effect is caused by metabolism rather than redistribution.
Hypothermia, such as may occur in cardiac surgery, may reduce clearance by
up to 20%.
There is some evidence to suggest that acute opioid tolerance and
hyperalgesia may occur, particularly after remifentanil infusions. If high
doses are used without neuromuscular blockade, muscle rigidity may be a
problem, though this is less likely if using a concentration of 100 μgml-1 or
less and an infusion rate of 0.2–0.5μgkg-1 min-1. Bradycardia has also been
reported.
