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 start and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial role in perioperative care, extensive care, and the management of acute, extreme discomfort. Due to the fact that of its effectiveness-- approximated to be 50 to 100 times that of morphine-- its administration through injection is strictly controlled and typically reserved for healthcare facility settings.
For health care specialists, students, or clients looking for to comprehend the pharmacological landscape in the UK, determining the available brand name names and manufacturers of fentanyl citrate injection is essential. This post offers an extensive introduction of the trademark name, clinical indications, 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 potent agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it provides fast 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 provide intense pain relief while maintaining hemodynamic stability, making it a favored choice for heart surgical treatments and for patients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, numerous pharmaceutical items are recommended by their generic name (Fentanyl) rather than a brand. Nevertheless, numerous producers provide the NHS and personal healthcare facilities with particular solutions. Historically, the most famous trademark name connected with fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized internationally 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
| Maker | Item 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 |

While the trademark name "Sublimaze" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic versions, which are bioequivalent to the original branded item.
Medical Indications for Injection
Fentanyl citrate injection is utilized across different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. It is used as an analgesic supplement during the induction and maintenance of general anaesthesia. It assists blunt the body's physiological "tension action" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, titrated boluses to manage 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 regularly utilized as an infusion to offer constant analgesia for clients who are mechanically ventilated. Its short half-life permits for more foreseeable "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 relocating to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to enhance discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents rising discomfort pathways, modifying the perception of and reaction to pain. read more increases the pain threshold.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier almost immediately, which describes why the analgesic impact is felt so much faster than with morphine or oxycodone.
Security and Side Effects
As with all powerful opioids, fentanyl citrate brings a threat of significant negative effects, especially relating to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most serious threat; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to aerate quickly (generally occurs with high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, typically around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression in the absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Policy and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to avoid diversion and misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dose administered must be taped in a Controlled Drugs Register, signed by two competent healthcare specialists (usually a physician and a nurse, or two nurses).
- Disposal: Any lost or unused portion of an ampoule need to be experienced and ruined according to regional trust policy (typically using a denaturing package).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK

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 typically readily available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in your home?
No. Fentanyl citrate injection is practically exclusively used in medical facility settings (theatre, ICU, A&E) because of the threat of rapid breathing depression, which needs immediate access to oxygen and resuscitation devices.
4. How does Fentanyl 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 (brand Prenoxad or generic) is the basic opioid villain utilized to reverse the impacts of fentanyl if respiratory anxiety takes place.
Summary
Fentanyl citrate remains one of the most vital medications in the UK's surgical and intensive care environments. While it might be referred to by the historical trademark name Sublimaze, it is primarily used in its generic kind supplied by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and rapid beginning make it an unrivaled tool for managing sharp pain and facilitating anaesthesia, however these very same qualities require the greatest level of medical tracking and regulative oversight. Comprehending the brand names and the medicinal profile of this drug is important for safe practice and patient security within the NHS and the wider UK health care sector.
