Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, commonly recognized in medical medication for its rapid start and short period of action. Within the United Kingdom's healthcare system, fentanyl plays a critical function in perioperative care, intensive care, and the management of severe, extreme pain. Because of its strength-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and normally scheduled for medical facility settings.
For healthcare experts, trainees, or clients looking for to understand the pharmacological landscape in the UK, determining the available brand and makers of fentanyl citrate injection is vital. This blog site post offers an extensive overview of the brand, scientific signs, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that acts as a powerful agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it offers 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 discomfort relief while maintaining hemodynamic stability, making it a preferred 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 recommended by their generic name (Fentanyl) instead of a brand. However, Fentanyl Citrate Injection Manufacturers UK provide the NHS and personal healthcare facilities with particular formulations. Historically, the most famous brand associated with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide and informally in some UK theatres, the bulk of the supply in the UK is now offered by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Product Description | Typical 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" might still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic versions, which are bioequivalent to the initial branded product.
Scientific Indications for Injection
Fentanyl citrate injection is utilized across numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into 3 categories:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep of basic 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 little, titrated boluses to manage immediate post-surgical pain before shifts 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 offer continuous analgesia for patients who are mechanically ventilated. Its short half-life enables more foreseeable "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 cooperate with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical pain stimulus during the treatment. |
| Analgesic Supplement | Used 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 ascending pain paths, changing the understanding of and action to discomfort. It also increases the pain 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 via the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier nearly quickly, which describes why the analgesic effect is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Just like all potent opioids, fentanyl citrate brings a danger of substantial adverse effects, particularly relating to the breathing and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most severe danger; it reduces the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to aerate easily (generally accompanies high-dose fast IV administration).
- Queasiness 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 lack of resuscitative devices.
- Concurrent usage 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 prevent diversion and abuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered must be tape-recorded in a Controlled Drugs Register, signed by two qualified health care specialists (generally a physician and a nurse, or more nurses).
- Disposal: Any squandered or unused portion of an ampoule should be seen and damaged according to regional trust policy (generally using a denaturing package).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the brand name Sublimaze is the "innovator" product, many UK health centers presently use generic variations made by companies like Hameln or Martindale. These are pharmacologically identical.
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 usually offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be given at home?
No. Fentanyl citrate injection is nearly specifically utilized in medical facility settings (theatre, ICU, A&E) since of the risk of fast breathing depression, which requires instant access to oxygen and resuscitation devices.
4. How does Legal Fentanyl UK compare to Morphine in strength?
Fentanyl is approximately 50 to 100 times more potent than morphine. This means 100 micrograms of fentanyl is roughly equivalent 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 anxiety happens.
Summary
Fentanyl citrate remains among the most vital medications in the UK's surgical and intensive care environments. While it might be described by the historical trademark name Sublimaze, it is mostly utilized in its generic kind supplied by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high strength and quick onset make it an unrivaled tool for managing severe discomfort and facilitating anaesthesia, however these exact same qualities demand the greatest level of clinical tracking and regulatory oversight. Understanding the brand names and the medicinal profile of this drug is necessary for safe practice and patient safety within the NHS and the larger UK healthcare sector.
