Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, extensively recognized in clinical medicine for its fast beginning and brief period of action. Within the United Kingdom's health care system, fentanyl plays a vital function in perioperative care, extensive care, and the management of severe, serious pain. Since of its potency-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and generally reserved for health center settings.
For health care professionals, students, or clients looking for to understand the medicinal landscape in the UK, recognizing the available brand and makers of fentanyl citrate injection is vital. This post provides a detailed overview of the brand name names, scientific indicators, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that serves as a potent agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it provides quick analgesia. In the UK, it is classified 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 capability to offer extreme pain 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 items are recommended by their generic name (Fentanyl) instead of a brand. However, several makers provide the NHS and personal health centers with specific formulations. Historically, the most popular trademark name associated with fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still used internationally and colloquially in some UK theatres, the majority of the supply in the UK is now provided 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 trademark name "Sublimaze" might still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic versions, which are bioequivalent to the original branded item.
Scientific Indications for Injection
Fentanyl citrate injection is utilized throughout various departments, from the Emergency Department (ED) to the Operating Theatre. Its use is generally divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. It is used as an analgesic supplement throughout the induction and upkeep 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 might 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 utilized as an infusion to supply continuous analgesia for patients who are mechanically aerated. Its short half-life permits 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 relocating to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To manage the surgical pain stimulus during the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to improve discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits ascending pain paths, changing the perception of and response to discomfort. It also increases the discomfort limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly instantly, which discusses why the analgesic result is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate brings a danger of significant side impacts, especially associating with the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most major danger; it lowers the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall becomes too stiff to aerate quickly (generally happens with high-dose rapid 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 absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation 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 taped in a Controlled Drugs Register, signed by two qualified healthcare experts (generally a medical professional and a nurse, or 2 nurses).
- Disposal: Any lost or unused portion of an ampoule need to be seen and destroyed according to local trust policy (normally utilizing a denaturing package).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the brand name Sublimaze is the "innovator" product, most UK health centers 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 basic concentration is 50 micrograms per millilitre (50 mcg/ml). It is generally readily available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in the house?
No. Fentanyl citrate injection is almost exclusively used in medical facility settings (theatre, ICU, A&E) because of the risk of quick breathing depression, which requires instant access to oxygen and resuscitation equipment.
4. How does Fentanyl compare to Morphine in strength?
Fentanyl is approximately 50 to 100 times more potent than morphine. This suggests 100 micrograms of fentanyl is approximately equivalent to 10 milligrams of morphine.
5. What is the antidote for a Fentanyl overdose?
Naloxone (brand Prenoxad or generic) is the standard opioid villain used to reverse the results of fentanyl if breathing anxiety occurs.
Summary
Fentanyl citrate stays among the most important medications in the UK's surgical and extensive care environments. While it might be described by the historic trademark name Sublimaze, it is mainly utilized in its generic form provided by producers such as Hameln, Wockhardt, and Martindale Pharma.
