Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, extensively acknowledged in clinical medicine for its quick onset and brief duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial role in perioperative care, intensive care, and the management of intense, extreme discomfort. Because of its strength-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and generally booked for health center settings.
For health care specialists, students, or clients looking for to comprehend the pharmacological landscape in the UK, recognizing the offered brand and manufacturers of fentanyl citrate injection is important. This blog site post offers a thorough summary of the brand name names, scientific indicators, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that serves as a powerful 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 supplies rapid analgesia. In the UK, it is categorized 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 extreme pain relief while maintaining hemodynamic stability, making it a preferred choice for heart surgeries and for clients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are prescribed by their generic name (Fentanyl) instead of a brand. However, several manufacturers provide the NHS and personal health centers with specific formulations. Historically, the most popular trademark name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and colloquially in some UK theatres, most of the supply in the UK is now provided by generic manufacturing specialists.
Table 1: Common Manufacturers and Product Details in the UK
| Maker | 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 "Sublimaze" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic variations, which are bioequivalent to the initial branded item.
Clinical Indications for Injection
Fentanyl citrate injection is made use of throughout numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and maintenance of basic anaesthesia. It assists 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 little, titrated boluses to manage immediate 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 frequently used as an infusion to offer continuous analgesia for clients who are mechanically ventilated. Its short half-life permits 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 relocating to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to improve discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits rising pain pathways, modifying the perception of and response to discomfort. It also increases the pain threshold.
- Start 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 through the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically quickly, which explains why the analgesic result is felt so much faster than with morphine or oxycodone.
Safety and Side Effects
As with all powerful opioids, fentanyl citrate carries a danger of considerable adverse effects, especially associating with the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe risk; it minimizes the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to aerate easily (usually takes place with high-dose fast IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety 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).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed 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 dosage administered need to be tape-recorded in a Controlled Drugs Register, signed by 2 certified healthcare experts (generally a physician and a nurse, or 2 nurses).
- Disposal: Any wasted or unused portion of an ampoule should be witnessed and destroyed according to local trust policy (typically utilizing a denaturing package).
FAQ: Fentanyl Citrate Injection in the UK

3. Can Fentanyl injection be offered at home?
No. Fentanyl citrate injection is almost solely used in hospital settings (theatre, ICU, A&E) because of the risk of rapid breathing depression, which needs immediate access to oxygen and resuscitation equipment.
