Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, commonly recognized in medical medicine for its rapid onset and short period of action. Within the United Kingdom's healthcare system, fentanyl plays a vital role in perioperative care, extensive care, and the management of severe, severe discomfort. Because of its effectiveness-- estimated to be 50 to 100 times that of morphine-- its administration through injection is strictly controlled and typically scheduled for health center settings.
For health care professionals, trainees, or patients looking for to comprehend the pharmacological landscape in the UK, identifying the available brand and makers of fentanyl citrate injection is essential. This blog site post offers a comprehensive summary of the trademark name, scientific indicators, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that serves 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 fast analgesia. In the UK, it is classified as a Class A managed 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 ability to provide extreme pain relief while keeping hemodynamic stability, making it a favored choice for cardiac surgeries and for clients with vulnerable 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. Nevertheless, a number of producers supply the NHS and private hospitals with specific formulations. Historically, the most well-known trademark name related to fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used globally and informally in some UK theatres, the majority of the supply in the UK is now offered by generic manufacturing experts.
Table 1: Common Manufacturers and Product Details in the UK
| Producer | Item Description | Common Strengths |
|---|---|---|
| Hameln Pharma | Fentanyl Citrate Injection BP | 50 micrograms/ml (2ml, 10ml ampoules) |
| Wockhardt UK | Fentanyl Citrate Injection | 50 micrograms/ml (2ml, 10ml ampoules) |
| Martindale Pharma | Fentanyl Citrate | 50 micrograms/ml (2ml, 10ml, 20ml ampoules) |
| Janssen-Cilag | Sublimaze (Historical Brand) | 50 micrograms/ml |
| Pirimal Critical Care | Fentanyl Citrate Injection | 50 micrograms/ml |
While the brand "Sublimaze" may still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic variations, which are bioequivalent to the initial branded item.
Scientific Indications for Injection
Fentanyl citrate injection is utilized across numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is normally divided into three classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is used as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "stress response" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle immediate 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 often utilized as an infusion to supply constant analgesia for patients who are mechanically ventilated. Buy Fentanyl In The UK -life enables more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To offer sedation and analgesia before transferring to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to boost pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain paths, changing the perception of and response to pain. It likewise increases the discomfort limit.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which explains why the analgesic result is felt so much faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all powerful opioids, fentanyl citrate carries a danger of considerable side effects, particularly associating with the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe risk; it minimizes the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to ventilate easily (usually accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- 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 equipment.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to avoid diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dosage administered should be tape-recorded in a Controlled Drugs Register, signed by two certified health care experts (usually a doctor and a nurse, or 2 nurses).
- Disposal: Any wasted or unused part of an ampoule must be witnessed and destroyed according to local trust policy (generally utilizing a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still readily available in the UK?

2. What is the basic concentration of Fentanyl injection in the UK?
The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is usually offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be offered in the house?
No. Fentanyl citrate injection is almost specifically utilized in healthcare facility settings (theatre, ICU, A&E) since of the risk of rapid breathing depression, which needs immediate access to oxygen and resuscitation equipment.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is roughly 50 to 100 times more powerful than morphine. This implies 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.

Naloxone (brand Prenoxad or generic) is the standard opioid villain utilized to reverse the impacts of fentanyl if respiratory depression takes place.
Summary
Fentanyl citrate stays among the most important medications in the UK's surgical and intensive care environments. While it might be referred to by the historical brand name Sublimaze, it is primarily used in its generic kind supplied by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and rapid start make it an unequaled tool for managing severe discomfort and helping with anaesthesia, but these same qualities demand the highest level of medical monitoring and regulative oversight. Understanding the brands and the medicinal profile of this drug is essential for safe practice and client safety within the NHS and the broader UK health care sector.
