Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, commonly recognized in scientific medication for its quick onset and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays an important role in perioperative care, intensive care, and the management of acute, serious discomfort. Since of its effectiveness-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and normally booked for hospital settings.
For health care specialists, students, or clients looking for to comprehend the medicinal landscape in the UK, determining the readily available trademark name and producers of fentanyl citrate injection is essential. This article provides a thorough introduction of the brand names, medical 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 central anxious system. When administered through intravenous (IV) or intramuscular (IM) injection, it provides quick 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 favored option for heart surgeries and for patients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, numerous pharmaceutical products are prescribed by their generic name (Fentanyl) rather than a trademark name. Nevertheless, numerous manufacturers provide the NHS and personal healthcare facilities with particular formulas. Historically, the most popular trademark name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide and colloquially in some UK theatres, most of the supply in the UK is now supplied by generic manufacturing 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 name "Sublimaze" might still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic versions, which are bioequivalent to the initial top quality product.
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 3 categories:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. Online Fentanyl Pharmacy UK is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "tension 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 transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently utilized as an infusion to supply continuous analgesia for patients who are mechanically aerated. Its short half-life permits more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To offer sedation and analgesia before moving to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Maintenance | To handle the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to boost discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents rising pain pathways, altering the perception of and action to pain. It also increases the discomfort limit.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier practically 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 brings a danger of considerable negative effects, particularly relating to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major threat; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to aerate easily (normally accompanies high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the lack 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).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to prevent 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 taped in a Controlled Drugs Register, signed by two competent healthcare experts (usually a medical professional and a nurse, or 2 nurses).
- Disposal: Any lost or unused part of an ampoule must be witnessed and destroyed according to regional trust policy (normally utilizing a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK

3. Can Fentanyl injection be given in the house?
No. Fentanyl citrate injection is nearly specifically used in medical facility settings (theatre, ICU, A&E) because of the threat of quick 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 powerful than morphine. This indicates 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.
