Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, extensively acknowledged in medical medicine for its rapid onset and brief period of action. Within the United Kingdom's health care system, fentanyl plays a vital role in perioperative care, intensive care, and the management of intense, severe pain. Because of its strength-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and usually reserved for medical facility settings.
For healthcare specialists, students, or clients looking for to understand the pharmacological landscape in the UK, determining the available brand name names and producers of fentanyl citrate injection is important. This post supplies an extensive overview of the brand names, clinical indicators, 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 main nervous system. When administered through intravenous (IV) or intramuscular (IM) injection, it provides quick analgesia. In the UK, it is categorized 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 ability to provide extreme discomfort relief while maintaining hemodynamic stability, making it a preferred option for heart surgeries and for clients with delicate 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) instead of a brand name. Nevertheless, Buy Fentanyl UK Bitcoin of producers provide the NHS and personal health centers with specific formulas. Historically, the most well-known trademark name associated with fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized internationally and colloquially in some UK theatres, the majority of the supply in the UK is now offered by generic production professionals.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | 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 dominated by Hameln and Martindale generic variations, which are bioequivalent to the initial branded product.
Scientific Indications for Injection
Fentanyl citrate injection is made use of throughout numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is normally divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It helps blunt the body's physiological "stress action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle immediate 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 frequently used as an infusion to supply constant analgesia for clients 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 | Role of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before relocating to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to boost discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain pathways, changing the understanding of and response to discomfort. It also increases the pain 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 via the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Since fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which describes why the analgesic impact is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate carries a threat of considerable side impacts, especially relating to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major risk; it lowers the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to ventilate quickly (generally occurs with high-dose rapid IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, typically 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).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to avoid diversion and abuse.
- Storage: It needs to 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 2 certified healthcare experts (generally a medical professional and a nurse, or more nurses).
- Disposal: Any lost or unused portion of an ampoule should be experienced and ruined according to local trust policy (usually utilizing a denaturing set).
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 health centers presently utilize generic variations produced by business 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 typically available in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be given in your home?
No. Fentanyl citrate injection is nearly exclusively used in hospital settings (theatre, ICU, A&E) since of the danger of fast 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. Fentanyl Liquid UK suggests 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 utilized to reverse the results of fentanyl if respiratory depression takes place.
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 historical trademark name Sublimaze, it is primarily utilized in its generic kind supplied by manufacturers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and fast beginning make it an exceptional tool for handling severe pain and facilitating anaesthesia, however these same qualities require the highest level of clinical monitoring and regulatory oversight. Understanding the brand names and the medicinal profile of this drug is essential for safe practice and client safety within the NHS and the wider UK healthcare sector.
