Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, extensively acknowledged in scientific medication for its quick beginning and short duration of action. Within the United Kingdom's health care system, fentanyl plays a vital function in perioperative care, intensive care, and the management of severe, serious discomfort. Due to the fact that of its potency-- estimated 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, trainees, or patients seeking to understand the pharmacological landscape in the UK, recognizing the readily available trademark name and producers of fentanyl citrate injection is important. This post provides a comprehensive introduction of the brand names, clinical 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the main anxious system. When administered via intravenous (IV) or intramuscular (IM) injection, it supplies fast analgesia. In click here , 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 primary appeal in surgical settings is its ability to offer extreme pain relief while maintaining hemodynamic stability, making it a preferred option for cardiac surgeries and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are recommended by their generic name (Fentanyl) rather than a brand name. Nevertheless, several makers provide the NHS and personal hospitals with particular formulations. Historically, the most popular trademark name connected with fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still used globally and colloquially in some UK theatres, the bulk of the supply in the UK is now provided by generic manufacturing professionals.
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 |
| Pirimal Critical Care | Fentanyl Citrate Injection | 50 micrograms/ml |
While the brand name "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 initial branded item.
Clinical Indications for Injection
Fentanyl citrate injection is used across different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep 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 might be administered in little, titrated boluses to handle instant 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 often used as an infusion to offer continuous analgesia for clients who are mechanically aerated. Its brief half-life permits 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 moving to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus throughout the procedure. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to enhance discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising discomfort pathways, altering the perception of and action to discomfort. It likewise increases the pain threshold.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier nearly immediately, which describes why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
As with all powerful opioids, fentanyl citrate carries a threat of considerable adverse effects, especially connecting to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it lowers 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 (usually accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the lack of resuscitative equipment.
- Concurrent usage 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 misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that fulfills the British Standard for security.
- Record Keeping: Every dosage administered should be tape-recorded in a Controlled Drugs Register, signed by 2 certified health care specialists (generally a medical professional and a nurse, or 2 nurses).
- Disposal: Any wasted or unused part of an ampoule need to be experienced and ruined according to local trust policy (typically utilizing a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the trademark name Sublimaze is the "innovator" item, many UK hospitals currently use generic versions made by business like Hameln or Martindale. These are pharmacologically similar.
2. What is the basic concentration of Fentanyl injection in the UK?
The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is normally offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in the house?
No. Fentanyl citrate injection is practically solely utilized in hospital settings (theatre, ICU, A&E) because of the risk of rapid respiratory anxiety, which needs instant access to oxygen and resuscitation devices.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is roughly 50 to 100 times more powerful than morphine. This means 100 micrograms of fentanyl is roughly equivalent to 10 milligrams of morphine.
5. What is the remedy for a Fentanyl overdose?
Naloxone (trademark name Prenoxad or generic) is the basic opioid villain utilized to reverse the impacts of fentanyl if respiratory anxiety takes place.
Summary
Fentanyl citrate remains one of the most crucial medications in the UK's surgical and intensive care environments. While it may be referred to by the historical trademark name Sublimaze, it is mostly utilized in its generic kind provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and fast start make it an exceptional tool for managing severe pain and helping with anaesthesia, but these same qualities demand the greatest level of medical tracking and regulative oversight. Understanding the brand names and the pharmacological profile of this drug is necessary for safe practice and client security within the NHS and the wider UK healthcare sector.
