Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, widely acknowledged in medical medicine for its rapid beginning and brief period of action. Within the United Kingdom's healthcare system, fentanyl plays a vital function in perioperative care, extensive care, and the management of intense, 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 usually scheduled for medical facility settings.
For healthcare experts, students, or clients seeking to understand the pharmacological landscape in the UK, determining the offered trademark name and manufacturers of fentanyl citrate injection is vital. This blog site post offers a thorough introduction of the brand, clinical signs, 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 through intravenous (IV) or intramuscular (IM) injection, it supplies 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 ability to offer intense discomfort relief while preserving hemodynamic stability, making it a favored option for cardiac surgeries and for patients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are recommended by their generic name (Fentanyl) instead of a brand. Nevertheless, a number of makers supply the NHS and private hospitals with specific solutions. Historically, the most famous brand connected with fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and informally in some UK theatres, most of the supply in the UK is now supplied by generic production professionals.
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" 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 top quality product.
Scientific Indications for Injection
Fentanyl citrate injection is utilized across various departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into 3 categories:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It helps blunt the body's physiological "stress reaction" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, 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 used as an infusion to provide constant analgesia for patients who are mechanically ventilated. Its brief half-life allows for more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To supply sedation and analgesia before relocating to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To manage the surgical discomfort stimulus throughout the procedure. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to boost discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits rising discomfort pathways, changing the perception of and reaction to discomfort. Fentanyl Citrate With Morphine UK increases the pain limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost instantly, which discusses why the analgesic impact is felt so much faster than with morphine or oxycodone.
Safety and Side Effects
As with all potent opioids, fentanyl citrate brings a risk of significant adverse effects, especially connecting to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe threat; it lowers the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to aerate easily (typically accompanies high-dose fast 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 depression in the lack of resuscitative devices.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat 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 avoid diversion and misuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that fulfills the British Standard for security.
- Record Keeping: Every dose administered should be tape-recorded in a Controlled Drugs Register, signed by two competent health care experts (normally a physician and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule need to be witnessed and damaged according to local trust policy (normally using a denaturing set).
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, most UK healthcare facilities currently use generic variations made by business 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). Legal Fentanyl UK is generally available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in your home?
No. Fentanyl citrate injection is nearly exclusively utilized in healthcare facility settings (theatre, ICU, A&E) since of the risk of rapid breathing depression, which requires instant access to oxygen and resuscitation equipment.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is around 50 to 100 times more powerful than morphine. This suggests 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.

Naloxone (brand name Prenoxad or generic) is the basic opioid villain used to reverse the results of fentanyl if respiratory depression occurs.
Summary
Fentanyl citrate stays one of the most crucial medications in the UK's surgical and extensive care environments. While it may be referred to by the historical brand name Sublimaze, it is mostly utilized in its generic form provided by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and quick start make it an exceptional tool for managing sharp pain and facilitating anaesthesia, but these same qualities require the highest level of scientific monitoring and regulative oversight. Comprehending the brand names and the pharmacological profile of this drug is important for safe practice and client security within the NHS and the wider UK health care sector.
