Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, widely acknowledged in clinical medicine for its quick onset and brief duration of action. Within the United Kingdom's health care system, fentanyl plays a vital role in perioperative care, intensive care, and the management of severe, serious pain. Because of its strength-- approximated to be 50 to 100 times that of morphine-- its administration via injection is strictly controlled and usually reserved for hospital settings.
For healthcare specialists, students, or patients looking for to comprehend the pharmacological landscape in the UK, identifying the readily available brand and producers of fentanyl citrate injection is necessary. This blog site post provides a thorough introduction of the trademark name, medical 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 central anxious system. When administered via intravenous (IV) or intramuscular (IM) injection, it provides rapid 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 capability to offer intense pain relief while keeping hemodynamic stability, making it a preferred choice for heart surgical treatments and for clients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical items are recommended by their generic name (Fentanyl) instead of a brand name. Nevertheless, a number of makers supply the NHS and personal healthcare facilities with specific formulas. Historically, the most popular brand name associated with fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide and informally in some UK theatres, the bulk of the supply in the UK is now offered by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Item Description | Common 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 brand "Sublimaze" might still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic variations, which are bioequivalent to the original branded item.
Medical Indications for Injection
Fentanyl citrate injection is made use of throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is generally divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. Buy Fentanyl From UK is used as an analgesic supplement during the induction and upkeep of basic anaesthesia. It assists blunt the body's physiological "tension response" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in little, titrated boluses to manage instant 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 regularly utilized as an infusion to supply constant analgesia for clients who are mechanically aerated. Its short half-life enables more predictable "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 moving to theatre. |
| Induction | To comply with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus during the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to boost pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending discomfort paths, modifying the perception of and response to pain. It likewise increases the discomfort threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly by means of 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.
Security and Side Effects
Similar to all potent opioids, fentanyl citrate carries a threat of substantial adverse effects, especially relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe danger; it decreases the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to ventilate easily (typically takes place with 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.
- Respiratory depression in the absence of resuscitative equipment.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Policy and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to prevent diversion and misuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dosage administered should be tape-recorded in a Controlled Drugs Register, signed by 2 competent healthcare experts (typically a physician and a nurse, or 2 nurses).
- Disposal: Any squandered or unused portion of an ampoule should be seen and destroyed according to regional trust policy (generally using a denaturing kit).
FAQ: Fentanyl Citrate Injection in the UK

The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is generally offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in the house?
No. Fentanyl citrate injection is nearly exclusively utilized in healthcare facility settings (theatre, ICU, A&E) because of the threat of rapid respiratory anxiety, which requires immediate access to oxygen and resuscitation devices.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is roughly 50 to 100 times more potent than morphine. This means 100 micrograms of fentanyl is roughly equivalent to 10 milligrams of morphine.

Summary
