Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, widely recognized in clinical medicine for its rapid start and short period of action. Within the United Kingdom's health care system, fentanyl plays a vital role in perioperative care, extensive care, and the management of acute, severe discomfort. Due to the fact that of its strength-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and generally booked for healthcare facility settings.
For health care professionals, students, or clients looking for to comprehend the pharmacological landscape in the UK, determining the offered trademark name and manufacturers of fentanyl citrate injection is essential. This blog site post provides a detailed overview of the brand names, clinical signs, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that acts as a powerful agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it offers 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 supply intense pain relief while keeping hemodynamic stability, making it a preferred choice for cardiac surgeries and for patients with fragile 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 brand name. However, numerous manufacturers provide the NHS and private medical facilities with particular solutions. Historically, the most well-known brand connected 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 majority of the supply in the UK is now offered by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Product 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) |
| 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 versions, which are bioequivalent to the initial top quality item.
Scientific Indications for Injection
Fentanyl citrate injection is used throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is normally divided into 3 categories:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. Fentanyl Pills UK is utilized as an analgesic supplement throughout the induction and maintenance of basic anaesthesia. It assists 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 small, 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 often used as an infusion to supply constant analgesia for patients who are mechanically ventilated. 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 transferring to theatre. |
| Induction | To comply with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical discomfort 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 prevents rising discomfort pathways, modifying the understanding of and response to pain. It also increases the pain limit.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier almost quickly, which discusses why the analgesic impact is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Just like all powerful opioids, fentanyl citrate carries a threat of substantial side results, especially relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe risk; it lowers the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to aerate easily (normally takes place with high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression 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 controlled to prevent diversion and misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered need to be taped in a Controlled Drugs Register, signed by 2 qualified health care experts (usually a medical professional and a nurse, or 2 nurses).
- Disposal: Any lost or unused portion of an ampoule should be witnessed and destroyed according to regional trust policy (typically using a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still offered in the UK?
While the brand name Sublimaze is the "innovator" item, the majority of UK medical facilities presently utilize generic variations made by companies like Hameln or Martindale. These are pharmacologically similar.
2. What is the standard concentration of Fentanyl injection in the UK?
The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is normally available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in your home?
No. Fentanyl citrate injection is nearly exclusively utilized in hospital settings (theatre, ICU, A&E) because of the danger of fast respiratory anxiety, which requires immediate access to oxygen and resuscitation equipment.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is around 50 to 100 times more powerful than morphine. This implies 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.
5. What is the antidote for a Fentanyl overdose?
Naloxone (trademark name Prenoxad or generic) is the basic opioid villain utilized to reverse the results of fentanyl if respiratory depression takes place.
Summary
Fentanyl citrate remains one of the most essential medications in the UK's surgical and intensive care environments. While it might be referred to by the historic brand name Sublimaze, it is mostly used in its generic type provided by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and rapid start make it an unequaled tool for handling sharp pain and facilitating anaesthesia, however these same qualities demand the greatest level of scientific monitoring and regulatory oversight. Understanding the brands and the medicinal profile of this drug is necessary for safe practice and client safety within the NHS and the broader UK healthcare sector.
