Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, commonly acknowledged in scientific medicine for its quick beginning and brief period of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial role in perioperative care, extensive care, and the management of acute, serious discomfort. Since of its potency-- estimated to be 50 to 100 times that of morphine-- its administration through injection is strictly controlled and typically reserved for hospital settings.
For healthcare experts, trainees, or clients looking for to comprehend the pharmacological landscape in the UK, identifying the available brand and producers of fentanyl citrate injection is vital. This article provides a thorough 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 functions as a powerful agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered through Fentanyl Pills UK (IV) or intramuscular (IM) injection, it supplies 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 provide intense pain relief while maintaining hemodynamic stability, making it a preferred option for cardiac surgeries and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical items are prescribed by their generic name (Fentanyl) instead of a brand. However, a number of producers supply the NHS and private health centers with specific solutions. Historically, the most popular 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, the bulk of the supply in the UK is now provided by generic manufacturing specialists.
Table 1: Common Manufacturers and Product Details in the UK
| Maker | 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 |

While the brand "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 top quality item.
Medical Indications for Injection
Fentanyl citrate injection is used across different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is used as an analgesic supplement during the induction and upkeep of basic anaesthesia. It helps 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 little, titrated boluses to manage immediate post-surgical pain before shifts 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 constant analgesia for patients who are mechanically aerated. Its short half-life enables more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To supply sedation and analgesia before moving to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus throughout the procedure. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to boost pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. Fentanyl Pills UK rising pain pathways, changing the understanding of and action to pain. It likewise increases the discomfort limit.
- Start 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 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 instantly, which describes why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Similar to all potent opioids, fentanyl citrate carries a danger of substantial negative effects, particularly connecting to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe risk; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to aerate quickly (typically occurs with high-dose fast IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression in the lack of resuscitative equipment.
- Concurrent use 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 avoid diversion and misuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dose administered must be tape-recorded in a Controlled Drugs Register, signed by two qualified health care specialists (typically a physician and a nurse, or more nurses).
- Disposal: Any lost or unused part of an ampoule need to be experienced and ruined according to regional trust policy (usually using a denaturing kit).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still readily available in the UK?
While the brand Sublimaze is the "innovator" item, a lot of UK medical facilities presently use generic variations made by business like Hameln or Martindale. These are pharmacologically similar.
2. What is the basic concentration 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 at home?
No. Fentanyl citrate injection is nearly specifically utilized in hospital settings (theatre, ICU, A&E) because of the risk of fast breathing 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 potent 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 (trademark name Prenoxad or generic) is the basic opioid antagonist utilized to reverse the impacts of fentanyl if respiratory depression happens.
Summary
Fentanyl citrate remains among the most essential medications in the UK's surgical and extensive care environments. While it might be described by the historic brand name Sublimaze, it is mostly used in its generic type provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high strength and rapid start make it an unequaled tool for handling intense discomfort and assisting in anaesthesia, but these same qualities demand the greatest level of clinical tracking and regulative 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.
