Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, commonly acknowledged in clinical medicine for its quick start and short duration of action. Within the United Kingdom's healthcare system, fentanyl plays a critical role in perioperative care, intensive care, and the management of acute, extreme discomfort. Due to the fact that of its potency-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and generally scheduled for hospital settings.
For healthcare specialists, students, or clients seeking to understand the medicinal landscape in the UK, determining the available brand name names and makers of fentanyl citrate injection is vital. This article offers a detailed introduction of the brand, scientific signs, 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 potent agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered through intravenous (IV) or intramuscular (IM) injection, it provides rapid 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 primary appeal in surgical settings is its capability to offer extreme pain relief while preserving hemodynamic stability, making it a favored option for heart surgeries and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are recommended by their generic name (Fentanyl) instead of a trademark name. However, a number of manufacturers provide the NHS and private healthcare facilities with specific formulas. Historically, the most well-known brand associated with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and informally in some UK theatres, the bulk 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) |

| Janssen-Cilag | Sublimaze (Historical Brand) | 50 micrograms/ml |
| Pirimal Critical Care | Fentanyl Citrate Injection | 50 micrograms/ml |
While the brand "Sublimaze" may 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.
Clinical Indications for Injection
Fentanyl citrate injection is used throughout numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is generally divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general 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 may be administered in little, titrated boluses to manage 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 offer constant analgesia for clients who are mechanically aerated. learn more -life permits for 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 transferring to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus during the procedure. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to improve discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending pain pathways, modifying the understanding of and response to discomfort. It likewise increases the discomfort threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolic process: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Because fentanyl is highly 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.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate carries a threat of significant side impacts, especially relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most major threat; it decreases the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to aerate quickly (typically accompanies high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression in the absence of resuscitative devices.
- Concurrent usage 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 controlled to avoid diversion and abuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that fulfills the British Standard for security.
- Record Keeping: Every dose administered must be taped in a Controlled Drugs Register, signed by 2 qualified health care experts (generally a medical professional and a nurse, or more nurses).
- Disposal: Any lost or unused portion of an ampoule should be witnessed and ruined according to local trust policy (typically utilizing a denaturing package).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still available in the UK?
While the trademark name Sublimaze is the "innovator" item, the majority of UK healthcare facilities currently use generic versions manufactured by business like Hameln or Martindale. These are pharmacologically similar.
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 generally offered in 2ml (100mcg) and 10ml (500mcg) ampoules.
3. Can Fentanyl injection be provided in the house?
No. Fentanyl citrate injection is nearly exclusively used in health center settings (theatre, ICU, A&E) because of the threat of quick breathing depression, which needs 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 implies 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 basic opioid antagonist utilized to reverse the impacts of fentanyl if respiratory depression occurs.
Summary
Fentanyl citrate stays among the most crucial medications in the UK's surgical and extensive care environments. While it may be described by the historic brand Sublimaze, it is mainly utilized in its generic form provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
Its high effectiveness and rapid onset make it an unparalleled tool for managing sharp pain and facilitating anaesthesia, but these exact same qualities demand the greatest level of medical tracking and regulative oversight. Understanding the brand names and the pharmacological profile of this drug is vital for safe practice and client security within the NHS and the broader UK health care sector.
