Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, widely acknowledged in medical medication for its rapid start and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial function in perioperative care, extensive care, and the management of severe, severe pain. Because of its effectiveness-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and normally booked for hospital settings.
For health care experts, students, or clients looking for to understand the pharmacological landscape in the UK, identifying the readily available trademark name and manufacturers of fentanyl citrate injection is essential. This article provides a detailed overview of the trademark name, medical 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 potent agonist at the μ-opioid (mu-opioid) receptors in the main worried system. When administered through 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 supply intense discomfort relief while keeping hemodynamic stability, making it a favored option for heart surgeries and for patients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are prescribed by their generic name (Fentanyl) instead of a brand name. Nevertheless, several producers supply the NHS and personal health centers with particular formulas. Historically, the most famous trademark name associated with fentanyl citrate was Sublimaze, initially developed 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 provided by generic production specialists.
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) |

While the brand name "Sublimaze" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic variations, which are bioequivalent to the original top quality product.
Clinical Indications for Injection
Fentanyl citrate injection is used across various departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern-day anaesthesia. Get Fentanyl In UK is used as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "tension reaction" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, 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 regularly utilized as an infusion to provide constant 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 | Role of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before relocating to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To handle the surgical discomfort stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending pain paths, altering the understanding of and action to discomfort. It also increases the discomfort limit.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier almost quickly, which describes why the analgesic result is felt so much faster than with morphine or oxycodone.
Security and Side Effects
As with all potent opioids, fentanyl citrate brings a threat of significant side impacts, especially associating with the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious risk; it reduces the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to aerate easily (typically accompanies high-dose fast IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression in the absence 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 regulated to prevent diversion and misuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cupboard that meets the British Standard for security.
- Record Keeping: Every dose administered should be tape-recorded in a Controlled Drugs Register, signed by 2 certified healthcare specialists (typically a physician and a nurse, or two nurses).
- Disposal: Any squandered or unused part of an ampoule must be experienced and destroyed according to local trust policy (usually 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" product, the majority of UK hospitals currently use generic variations made 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 available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be offered in your home?
No. click here is practically solely used in healthcare facility settings (theatre, ICU, A&E) because of the threat of rapid respiratory depression, which needs immediate 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 means 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.
5. What is the remedy for a Fentanyl overdose?
Naloxone (trademark name Prenoxad or generic) is the basic opioid antagonist used to reverse the results of fentanyl if respiratory anxiety occurs.
Summary
Fentanyl citrate stays one of the most important medications in the UK's surgical and intensive care environments. While it might be described by the historic brand name Sublimaze, it is primarily used in its generic form provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high strength and rapid beginning make it an exceptional tool for managing sharp pain and assisting in anaesthesia, but these same qualities require the highest level of scientific tracking and regulatory oversight. Understanding the brands and the pharmacological profile of this drug is necessary for safe practice and patient safety within the NHS and the larger UK health care sector.
