Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, commonly recognized in scientific medicine for its fast onset and short period of action. Within the United Kingdom's health care system, fentanyl plays a critical role in perioperative care, extensive care, and the management of acute, severe discomfort. Since of its strength-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and usually booked for health center settings.
For health care specialists, students, or clients looking for to understand the pharmacological landscape in the UK, recognizing the readily available brand and makers of fentanyl citrate injection is important. This article offers a thorough summary of the trademark name, scientific indicators, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that functions as a powerful agonist at the μ-opioid (mu-opioid) receptors in the central nervous system. When administered through intravenous (IV) or intramuscular (IM) injection, it provides quick analgesia. In the UK, it is categorized 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 ability to provide extreme discomfort relief while preserving hemodynamic stability, making it a favored choice for cardiac surgical treatments and for clients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical products are recommended by their generic name (Fentanyl) instead of a brand. However, a number of makers supply the NHS and personal health centers with specific formulas. Historically, the most famous brand related to fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still used globally and colloquially in some UK theatres, the majority of the supply in the UK is now provided by generic manufacturing professionals.
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 versions, which are bioequivalent to the original branded product.
Scientific Indications for Injection
Fentanyl citrate injection is used across various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is typically divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. It is used as an analgesic supplement during the induction and upkeep of general 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 shifts are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is regularly utilized as an infusion to offer continuous analgesia for patients who are mechanically aerated. Its brief half-life enables more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To supply sedation and analgesia before relocating to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to enhance pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents rising pain paths, changing the understanding of and action to discomfort. It also increases the discomfort threshold.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically immediately, which explains why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate brings a danger of significant side effects, particularly connecting to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it decreases the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to ventilate easily (generally happens with high-dose quick IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, frequently around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk 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 prevent diversion and misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cabinet that fulfills the British Standard for security.
- Record Keeping: Every dose administered must be taped in a Controlled Drugs Register, signed by 2 qualified health care professionals (typically a doctor and a nurse, or two nurses).
- Disposal: Any lost or unused portion of an ampoule must be seen and ruined according to regional trust policy (usually using a denaturing set).
FAQ: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the brand Sublimaze is the "innovator" product, a lot of UK healthcare facilities currently utilize generic versions made by companies like Hameln or Martindale. These are pharmacologically similar.
2. What is the basic concentration of Fentanyl injection in the UK?
The basic concentration is 50 micrograms per millilitre (50 mcg/ml). It is generally available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be given in the house?
No. Fentanyl citrate injection is almost specifically used in hospital settings (theatre, ICU, A&E) since of the threat of fast respiratory anxiety, which needs instant access to oxygen and resuscitation devices.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is roughly 50 to 100 times more powerful than morphine. learn more indicates 100 micrograms of fentanyl is approximately equivalent to 10 milligrams of morphine.

Naloxone (brand Prenoxad or generic) is the standard opioid villain utilized to reverse the results of fentanyl if respiratory depression takes place.
Summary
Fentanyl citrate stays among the most vital medications in the UK's surgical and extensive care environments. While it might be referred to by the historic brand Sublimaze, it is primarily used in its generic type provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and quick start make it an unrivaled tool for handling sharp pain and facilitating anaesthesia, but these same qualities necessitate the greatest level of scientific tracking and regulative oversight. Comprehending the brand names and the pharmacological profile of this drug is necessary for safe practice and client safety within the NHS and the larger UK health care sector.
