Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, extensively recognized in clinical medicine for its rapid onset and short period of action. Within the United Kingdom's health care system, fentanyl plays a critical function in perioperative care, intensive care, and the management of severe, extreme pain. Since of Fentanyl Sticks UK -- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and typically scheduled for healthcare facility settings.
For healthcare specialists, trainees, or patients seeking to comprehend the medicinal landscape in the UK, recognizing the offered brand and producers of fentanyl citrate injection is essential. This blog site post offers an extensive summary of the brand, scientific indications, 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the central nervous system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it supplies quick analgesia. In the UK, it is categorized 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 maintaining hemodynamic stability, making it a favored option for heart surgical treatments 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 recommended by their generic name (Fentanyl) rather than a trademark name. However, numerous manufacturers provide the NHS and private medical facilities with particular formulas. Historically, the most well-known brand related to fentanyl citrate was Sublimaze, originally established 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 professionals.
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) |
| 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" might still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic versions, which are bioequivalent to the original top quality product.
Scientific Indications for Injection
Fentanyl citrate injection is made use of across different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is usually divided into three classifications:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and maintenance of general anaesthesia. It assists blunt the body's physiological "stress action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, titrated boluses to handle 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 regularly used as an infusion to supply continuous analgesia for patients who are mechanically aerated. Its short half-life permits for 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 transferring to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to enhance pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising discomfort pathways, changing the understanding of and action to discomfort. It also increases the pain threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly quickly, which discusses why the analgesic effect is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
As with all powerful opioids, fentanyl citrate carries a danger of substantial side impacts, especially relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most major risk; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to aerate easily (typically accompanies high-dose fast IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, typically around the nose or upper body.
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 (danger 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 must be kept in a locked "Controlled Drugs" (CD) cabinet that satisfies the British Standard for security.
- Record Keeping: Every dosage administered must be tape-recorded in a Controlled Drugs Register, signed by two competent healthcare specialists (usually a medical professional and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule must be seen and destroyed according to regional trust policy (typically using a denaturing package).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still readily available in the UK?
While the brand name Sublimaze is the "innovator" item, the majority of UK healthcare facilities currently use generic variations manufactured by business like Hameln or Martindale. These are pharmacologically identical.
2. What is the basic concentration of Fentanyl injection in the UK?
The basic 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 at home?
No. Fentanyl citrate injection is nearly solely utilized in health center settings (theatre, ICU, A&E) because of the threat of rapid respiratory depression, which requires instant access to oxygen and resuscitation devices.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is approximately 50 to 100 times more powerful than morphine. This means 100 micrograms of fentanyl is roughly comparable to 10 milligrams of morphine.
5. What is the antidote for a Fentanyl overdose?
Naloxone (brand Prenoxad or generic) is the standard opioid antagonist used to reverse the results of fentanyl if respiratory depression happens.
Summary
Fentanyl citrate remains among the most crucial medications in the UK's surgical and extensive care environments. While it might be described by the historic trademark name Sublimaze, it is mainly used in its generic type supplied by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high strength and quick onset make it an unparalleled tool for handling sharp pain and facilitating anaesthesia, but these very same qualities require the greatest level of medical monitoring and regulatory oversight. Understanding the brand names and the medicinal profile of this drug is important for safe practice and patient safety within the NHS and the wider UK healthcare sector.
