Here's An Interesting Fact About Fentanyl Citrate Injection Brand Names UK. Fentanyl Citrate Injection Brand Names UK
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 medicine for its rapid start and brief period of action. Within the United Kingdom's health care system, fentanyl plays a critical role in perioperative care, intensive care, and the management of intense, serious discomfort. Since of its potency-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and generally booked for medical facility settings.
For healthcare experts, trainees, or clients looking for to understand the pharmacological landscape in the UK, determining the offered brand and producers of fentanyl citrate injection is vital. This post provides an extensive summary of the brand name names, medical signs, 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 main nervous system. When administered through intravenous (IV) or intramuscular (IM) injection, it offers rapid 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 primary appeal in surgical settings is its ability to provide intense pain relief while preserving hemodynamic stability, making it a preferred option for cardiac surgeries and for patients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, numerous pharmaceutical items are prescribed by their generic name (Fentanyl) rather than a trademark name. Nevertheless, a number of manufacturers provide the NHS and private health centers with specific solutions. Historically, the most popular brand associated with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide 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
| Maker | 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 trademark name "Sublimaze" may still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic variations, which are bioequivalent to the original top quality item.
Medical Indications for Injection
Fentanyl citrate injection is used across different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is normally divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "tension response" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle instant 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 offer continuous analgesia for clients who are mechanically aerated. Its brief half-life permits for more predictable "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 work together with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus throughout 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 hinders ascending discomfort paths, altering the understanding of and action to discomfort. 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).
- Metabolism: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically quickly, which describes why the analgesic result is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all potent opioids, fentanyl citrate carries a risk of substantial negative effects, especially connecting to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most serious threat; it reduces 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 aerate quickly (normally occurs with high-dose fast 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 depression in the lack 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).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to prevent diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered should be taped in a Controlled Drugs Register, signed by 2 competent health care professionals (normally a doctor and a nurse, or 2 nurses).
- Disposal: Any squandered or unused portion of an ampoule need to be witnessed and destroyed according to regional trust policy (typically using a denaturing package).
FAQ: Fentanyl Citrate Injection in the UK

2. What is Fentanyl Citrate Injection Formulations UK of Fentanyl injection in the UK?
The basic concentration is 50 micrograms per millilitre (50 mcg/ml). It is generally available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be offered at home?
No. Fentanyl citrate injection is almost solely used in hospital settings (theatre, ICU, A&E) due to the fact that of the risk of rapid respiratory anxiety, which requires immediate access to oxygen and resuscitation equipment.

Fentanyl is roughly 50 to 100 times more potent than morphine. This means 100 micrograms of fentanyl is approximately equivalent to 10 milligrams of morphine.

Naloxone (brand Prenoxad or generic) is the basic opioid antagonist used to reverse the impacts of fentanyl if breathing depression takes place.
Summary
Fentanyl citrate remains one of the most essential medications in the UK's surgical and extensive care environments. While it may be referred to by the historic brand Sublimaze, it is mainly utilized in its generic form supplied by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and quick onset make it an unrivaled tool for handling sharp pain and assisting in anaesthesia, but these exact same qualities demand the greatest level of clinical tracking and regulative oversight. Understanding learn more and the pharmacological profile of this drug is vital for safe practice and patient security within the NHS and the broader UK health care sector.
