Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, commonly acknowledged in medical medicine for its rapid start and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays an important role in perioperative care, extensive care, and the management of intense, serious discomfort. Since of its potency-- estimated to be 50 to 100 times that of morphine-- its administration through injection is strictly managed and generally booked for health center settings.
For healthcare specialists, students, or patients seeking to comprehend the pharmacological landscape in the UK, determining the readily available brand and manufacturers of fentanyl citrate injection is vital. This post provides a comprehensive overview 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 serves as a powerful agonist at the μ-opioid (mu-opioid) receptors in the main worried system. When administered through intravenous (IV) or intramuscular (IM) injection, it provides fast 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 primary appeal in surgical settings is its capability to offer extreme pain relief while maintaining hemodynamic stability, making it a preferred option for heart surgical treatments 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 prescribed by their generic name (Fentanyl) instead of a brand. However, medicstoregb.uk of producers supply the NHS and personal health centers with specific formulations. Historically, the most popular trademark name related to fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still used worldwide and colloquially in some UK theatres, most of the supply in the UK is now provided by generic manufacturing professionals.
Table 1: Common Manufacturers and Product Details in the UK
| Producer | 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 brand 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 product.
Medical Indications for Injection
Fentanyl citrate injection is used across different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is usually divided into 3 categories:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep of basic anaesthesia. It helps blunt the body's physiological "tension 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 instant 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 regularly utilized as an infusion to supply continuous analgesia for patients who are mechanically aerated. Its short half-life allows for more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To offer 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 pain stimulus during the treatment. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to enhance pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending discomfort pathways, modifying the perception of and reaction to pain. It likewise increases the discomfort limit.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it highly titratable).
- Metabolic process: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which describes why the analgesic effect is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate brings a threat of considerable negative effects, especially connecting to the respiratory and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major threat; it decreases the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to ventilate easily (typically accompanies high-dose fast IV administration).
- Nausea and Vomiting: Common in the post-operative stage.
- 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 devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to prevent diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cupboard that fulfills the British Standard for security.
- Record Keeping: Every dosage administered should be taped in a Controlled Drugs Register, signed by two competent healthcare professionals (normally a medical professional and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule need to be seen and damaged according to local trust policy (usually using a denaturing set).
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
1. Is Sublimaze still readily available in the UK?

3. Can Fentanyl injection be provided at home?
No. Fentanyl citrate injection is almost exclusively utilized in healthcare facility settings (theatre, ICU, A&E) due to the fact that of the risk of fast respiratory anxiety, which requires immediate 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 indicates 100 micrograms of fentanyl is roughly comparable to 10 milligrams of morphine.
