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 medical medication for its quick onset and short duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial function in perioperative care, intensive care, and the management of acute, serious discomfort. Due to the fact that of its effectiveness-- 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 experts, students, or patients looking for to understand the pharmacological landscape in the UK, determining the offered trademark name and producers of fentanyl citrate injection is necessary. This blog site post supplies a detailed introduction of the brand, clinical indications, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that functions as a potent agonist at the μ-opioid (mu-opioid) receptors in the main worried system. When administered via intravenous (IV) or intramuscular (IM) injection, it supplies rapid analgesia. In Fentanyl Sticks 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 intense discomfort relief while preserving hemodynamic stability, making it a preferred choice for heart surgical treatments and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are recommended by their generic name (Fentanyl) rather than a trademark name. Nevertheless, several producers supply the NHS and private medical facilities with particular formulations. Historically, the most well-known trademark name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and informally 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 | 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" 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 branded item.
Scientific Indications for Injection
Fentanyl citrate injection is used throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into three categories:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep of general anaesthesia. It helps blunt the body's physiological "tension response" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, titrated boluses to manage immediate 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 constant analgesia for patients who are mechanically aerated. Its short half-life enables 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 cooperate with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to enhance pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits ascending discomfort pathways, modifying the understanding of and reaction to discomfort. It also increases the pain limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically quickly, which discusses why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
As with all potent opioids, fentanyl citrate carries a threat of significant negative effects, particularly relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious risk; it lowers 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 quickly (usually takes place with high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the lack of resuscitative equipment.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Policy 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) cabinet that meets the British Standard for security.
- Record Keeping: Every dosage administered should be recorded in a Controlled Drugs Register, signed by two qualified healthcare experts (generally a doctor and a nurse, or 2 nurses).
- Disposal: Any squandered or unused portion of an ampoule should be seen and destroyed according to regional trust policy (usually utilizing a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still offered in the UK?
While the brand Sublimaze is the "innovator" product, most UK healthcare facilities presently utilize generic variations manufactured by business like Hameln or Martindale. These are pharmacologically similar.
2. What is Fentanyl Citrate With Morphine UK of Fentanyl injection in the UK?
The standard concentration is 50 micrograms per millilitre (50 mcg/ml). It is normally readily available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be given in the house?
No. Fentanyl citrate injection is almost solely utilized in hospital settings (theatre, ICU, A&E) due to the fact that of the danger of quick 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 equivalent to 10 milligrams of morphine.
5. What is the remedy for a Fentanyl overdose?
Naloxone (brand name Prenoxad or generic) is the standard opioid villain used to reverse the results of fentanyl if breathing depression happens.
Summary
Fentanyl citrate stays among the most vital medications in the UK's surgical and extensive care environments. While it might be referred to by the historic brand Sublimaze, it is mainly utilized in its generic type supplied by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high potency and quick beginning make it an unparalleled tool for handling intense discomfort and assisting in anaesthesia, however these exact same qualities demand the highest level of scientific tracking and regulative oversight. Understanding the brands and the pharmacological profile of this drug is important for safe practice and client safety within the NHS and the wider UK health care sector.
