When administered by means of intravenous (IV) or intramuscular (IM) injection, it supplies rapid analgesia. In the UK, it is classified as a Class A controlled drug under the Misuse of Drugs Act 1971 and falls under Schedule 2 of the Misuse of Drugs Regulations 2001.
Its main appeal in surgical settings is its capability to supply intense pain relief while keeping hemodynamic stability, making it a favored option for heart surgical treatments and for clients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are prescribed by their generic name (Fentanyl) instead of a brand name. However, several producers provide the NHS and private medical facilities with particular solutions. Historically, the most popular brand name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and colloquially in some UK theatres, the bulk of the supply in the UK is now offered by generic manufacturing experts.

Clinical Indications for Injection
Fentanyl citrate injection is made use of throughout various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into three classifications:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "stress action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to manage instant post-surgical pain before transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently used as an infusion to supply continuous analgesia for patients who are mechanically ventilated. Its short half-life allows for more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before moving to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to boost discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising discomfort paths, changing the perception of and action to discomfort. It likewise increases the pain limit.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolic process: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost quickly, which discusses why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Just like all powerful opioids, fentanyl citrate brings a threat of considerable negative effects, particularly associating with the breathing and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most severe danger; it reduces the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to ventilate easily (normally happens with high-dose fast IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, frequently around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression in the lack of resuscitative equipment.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to prevent diversion and abuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that meets the British Standard for security.
- Record Keeping: Every dose administered must be taped in a Controlled Drugs Register, signed by 2 qualified healthcare specialists (typically a physician and a nurse, or 2 nurses).
- Disposal: Any wasted or unused part of an ampoule need to be experienced and ruined according to regional trust policy (typically using a denaturing kit).
