Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, extensively acknowledged in clinical medicine for its quick beginning and short duration of action. Within the United Kingdom's healthcare system, fentanyl plays an important function in perioperative care, intensive care, and the management of severe, extreme discomfort. Since of its effectiveness-- estimated to be 50 to 100 times that of morphine-- its administration through injection is strictly controlled and usually reserved for health center settings.
For health care experts, students, or patients seeking to understand the medicinal landscape in the UK, recognizing the available brand name names and producers of fentanyl citrate injection is vital. website offers a detailed introduction of the brand names, clinical indicators, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that functions as a potent agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered via intravenous (IV) or intramuscular (IM) injection, it supplies quick 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 primary appeal in surgical settings is its capability to supply extreme discomfort relief while maintaining hemodynamic stability, making it a favored choice for heart surgeries and for patients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical items are prescribed by their generic name (Fentanyl) rather than a brand name. However, several producers provide the NHS and personal medical facilities with specific formulas. Historically, the most well-known brand connected with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still used globally and informally in some UK theatres, the bulk of the supply in the UK is now supplied by generic manufacturing experts.

Medical Indications for Injection
Fentanyl citrate injection is utilized across numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It helps blunt the body's physiological "tension action" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in little, titrated boluses to handle instant post-surgical discomfort before transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently utilized as an infusion to offer constant analgesia for patients who are mechanically ventilated. Its brief half-life enables more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To supply sedation and analgesia before transferring to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to improve pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain paths, changing the understanding of and action to discomfort. It likewise increases the discomfort threshold.
- Onset 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 by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly quickly, which discusses why the analgesic result is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate brings a threat of substantial side results, especially relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious threat; it decreases the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to ventilate quickly (normally happens with high-dose rapid IV administration).
- Queasiness 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 anxiety in the absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Policy and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to avoid diversion and abuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dose administered need to be taped in a Controlled Drugs Register, signed by 2 qualified healthcare specialists (normally a medical professional and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule need to be seen and destroyed according to regional trust policy (generally using a denaturing kit).
