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 medical medication for its rapid onset and short period of action. Within the United Kingdom's healthcare system, fentanyl plays an important function in perioperative care, extensive care, and the management of acute, serious pain. Because of its strength-- estimated to be 50 to 100 times that of morphine-- its administration through injection is strictly managed and normally scheduled for medical facility settings.
For health care experts, students, or clients looking for to understand the medicinal landscape in the UK, recognizing the offered brand name names and manufacturers of fentanyl citrate injection is necessary. This article supplies a detailed summary of the brand, medical signs, 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 potent agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered via intravenous (IV) or intramuscular (IM) injection, it provides quick analgesia. In Fentanyl Citrate Indications 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 ability to supply extreme discomfort relief while keeping hemodynamic stability, making it a preferred option for heart surgical treatments and for clients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical products are prescribed by their generic name (Fentanyl) rather than a brand name. However, a number of makers supply the NHS and personal healthcare facilities with particular formulations. Historically, the most famous brand name associated with fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide and colloquially in some UK theatres, the majority of the supply in the UK is now offered by generic manufacturing experts.
Table 1: Common Manufacturers and Product Details in the UK
| Maker | Item Description | Common Strengths |
|---|---|---|
| Hameln Pharma | Fentanyl Citrate Injection BP | 50 micrograms/ml (2ml, 10ml ampoules) |

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 original top quality item.
Clinical Indications for Injection
Fentanyl citrate injection is used across numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is used as an analgesic supplement throughout the induction and maintenance of general anaesthesia. It assists blunt the body's physiological "stress response" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, 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 regularly used as an infusion to supply continuous analgesia for patients who are mechanically ventilated. Its short half-life permits for more foreseeable "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 transition to unconsciousness. |
| Maintenance | To handle 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 rising discomfort paths, modifying the understanding of and action to discomfort. It also increases the pain threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly quickly, which describes why the analgesic impact is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all powerful opioids, fentanyl citrate carries a danger of significant negative effects, particularly relating to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major risk; it lowers 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 ventilate easily (normally accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, frequently around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the lack 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 misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that meets the British Standard for security.
- Record Keeping: Every dose administered should be tape-recorded in a Controlled Drugs Register, signed by two qualified healthcare specialists (generally a medical professional and a nurse, or 2 nurses).
- Disposal: Any wasted or unused part of an ampoule need to be witnessed and ruined according to local trust policy (typically utilizing a denaturing kit).
FAQ: Fentanyl Citrate Injection in the UK
