Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, extensively acknowledged in scientific medication for its quick start and short duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial role in perioperative care, extensive care, and the management of intense, severe pain. Because of its potency-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and normally scheduled for hospital settings.
For healthcare specialists, students, or clients seeking to understand the medicinal landscape in the UK, identifying the offered brand names and producers of fentanyl citrate injection is vital. This blog site post offers an extensive overview of the trademark name, scientific indications, 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 potent agonist at the μ-opioid (mu-opioid) receptors in the main anxious system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it offers quick 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 main appeal in surgical settings is its ability to provide extreme pain relief while keeping hemodynamic stability, making it a preferred choice for cardiac surgeries and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are recommended by their generic name (Fentanyl) instead of a trademark name. However, a number of makers supply the NHS and private medical facilities with particular formulas. Historically, the most popular trademark name related to fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used globally and colloquially in some UK theatres, most of the supply in the UK is now provided 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 trademark name "Sublimaze" might still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic versions, which are bioequivalent to the original top quality item.
Medical Indications for Injection
Fentanyl citrate injection is utilized throughout various departments, from the Emergency Department (ED) to the Operating Theatre. Its use is generally divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "stress response" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, 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 often used as an infusion to provide continuous analgesia for clients who are mechanically aerated. Its brief half-life permits for more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before moving to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to improve pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending discomfort paths, modifying the perception of and response to pain. It likewise 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 by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Due to the fact that fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost quickly, which discusses why the analgesic result is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Similar to all potent opioids, fentanyl citrate carries a danger of significant adverse effects, particularly relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe danger; it reduces 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 (generally accompanies high-dose rapid IV administration).
- Queasiness 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 depression in the absence of resuscitative equipment.
- 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 regulated to prevent diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dose administered should be recorded in a Controlled Drugs Register, signed by two certified health care professionals (usually a physician and a nurse, or 2 nurses).
- Disposal: Any wasted or unused portion of an ampoule need to be witnessed and ruined according to local trust policy (normally utilizing a denaturing set).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the brand Sublimaze is the "innovator" product, many UK hospitals currently use generic versions produced by business like Hameln or Martindale. These are pharmacologically identical.

The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is normally offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in the house?
No. Fentanyl citrate injection is almost specifically utilized in medical facility settings (theatre, ICU, A&E) because of the risk of fast respiratory depression, which needs instant access to oxygen and resuscitation equipment.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is roughly 50 to 100 times more potent than morphine. This indicates 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.

Naloxone (brand name Prenoxad or generic) is the standard opioid antagonist utilized to reverse the results of fentanyl if respiratory anxiety occurs.
Summary
Fentanyl citrate remains among the most crucial medications in the UK's surgical and extensive care environments. While it may be described by the historic brand name Sublimaze, it is primarily used in its generic kind supplied by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and quick start make it an exceptional tool for managing intense discomfort and assisting in anaesthesia, but these very same qualities necessitate the greatest level of scientific monitoring and regulative oversight.
