Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, widely acknowledged in medical medication for its fast beginning and short duration of action. Within the United Kingdom's health care system, fentanyl plays an important role in perioperative care, intensive care, and the management of acute, severe discomfort. Since of its effectiveness-- approximated to be 50 to 100 times that of morphine-- its administration through injection is strictly managed and usually booked for medical facility settings.
For health care experts, students, or patients seeking to comprehend the medicinal landscape in the UK, identifying the offered trademark name and producers of fentanyl citrate injection is important. This article provides a thorough overview of the brand, scientific signs, 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the central worried system. When administered through 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 supply intense pain relief while preserving hemodynamic stability, making it a preferred option 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 products are recommended by their generic name (Fentanyl) instead of a brand name. However, several manufacturers supply the NHS and personal health centers with particular formulas. Historically, the most famous brand name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used internationally and informally in some UK theatres, most of the supply in the UK is now provided by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Product 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 name "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 top quality product.
Medical Indications for Injection
Fentanyl citrate injection is utilized throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is usually divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It assists blunt the body's physiological "tension reaction" 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 pain before transitions 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 | Role of Fentanyl |
|---|---|
| Pre-medication | To offer sedation and analgesia before moving to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Maintenance | To handle the surgical pain stimulus during the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to improve pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain paths, changing the understanding of and response to pain. It also increases the pain threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier nearly quickly, which describes why the analgesic result is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Just like all potent opioids, fentanyl citrate carries a risk of substantial side results, particularly relating to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major risk; it reduces the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to aerate easily (generally accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or upper body.
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 (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled 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 dosage administered must be taped in a Controlled Drugs Register, signed by 2 qualified healthcare specialists (usually a medical professional and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule must be experienced and destroyed according to local trust policy (typically using a denaturing package).
FAQ: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still readily available in the UK?
While the brand Sublimaze is the "innovator" product, most UK medical facilities currently utilize generic variations manufactured by business like Hameln or Martindale. These are pharmacologically similar.
2. What is learn more of Fentanyl injection in the UK?
The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is normally available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in your home?
No. Fentanyl citrate injection is practically solely used in medical facility settings (theatre, ICU, A&E) due to the fact that of the threat of fast breathing anxiety, which needs instant access to oxygen and resuscitation devices.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is around 50 to 100 times more potent than morphine. This means 100 micrograms of fentanyl is roughly comparable to 10 milligrams of morphine.

Naloxone (trademark name Prenoxad or generic) is the basic opioid villain utilized to reverse the results 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 described by the historical brand Sublimaze, it is mostly utilized in its generic kind provided by producers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and rapid start make it an unequaled tool for handling sharp pain and helping with anaesthesia, however these same qualities necessitate the highest level of scientific tracking 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 wider UK healthcare sector.
