Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, extensively recognized in clinical medication for its quick beginning and short duration of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial function in perioperative care, intensive care, and the management of acute, extreme discomfort. Because of its effectiveness-- estimated to be 50 to 100 times that of morphine-- its administration via injection is strictly controlled and normally booked for hospital settings.
For healthcare specialists, trainees, or patients looking for to comprehend the medicinal landscape in the UK, recognizing the available trademark name and makers of fentanyl citrate injection is vital. This article offers a thorough summary of the brand name names, clinical indicators, 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 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 supplies quick analgesia. In the UK, it is categorized 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 capability to offer extreme discomfort relief while preserving hemodynamic stability, making it a preferred option for heart surgical treatments and for clients with vulnerable 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 name. Nevertheless, numerous producers supply the NHS and private health centers with particular solutions. Historically, the most popular trademark name associated with fentanyl citrate was Sublimaze, originally established 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 offered by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Producer | 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) |

While the brand "Sublimaze" might still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic variations, which are bioequivalent to the original branded product.
Clinical Indications for Injection
Fentanyl citrate injection is utilized across different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "tension action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in little, titrated boluses to handle 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 used as an infusion to provide constant analgesia for clients who are mechanically ventilated. Its brief half-life enables 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 work together with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus throughout the procedure. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to boost pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain pathways, changing the perception of and action to pain. It also increases the discomfort threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically quickly, which explains why the analgesic impact is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate brings a risk of significant side impacts, particularly connecting to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it lowers the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to ventilate easily (generally takes place with high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression in the absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to prevent diversion and misuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dosage administered must be tape-recorded in a Controlled Drugs Register, signed by two competent healthcare experts (normally a doctor and a nurse, or 2 nurses).
- Disposal: Any lost or unused part of an ampoule must be seen and ruined according to local trust policy (normally using a denaturing set).
