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 medical medicine for its fast beginning and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial role in perioperative care, extensive care, and the management of severe, severe pain. Due to the fact that of its strength-- estimated to be 50 to 100 times that of morphine-- its administration via injection is strictly controlled and typically scheduled for health center settings.
For health care professionals, students, or patients seeking to understand the medicinal landscape in the UK, identifying the readily available trademark name and manufacturers of fentanyl citrate injection is important. This post offers a comprehensive summary of the brand name names, 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the main nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it provides fast 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 ability to provide intense pain relief while preserving hemodynamic stability, making it a favored choice 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, lots of pharmaceutical items are prescribed by their generic name (Fentanyl) instead of a brand. However, numerous manufacturers provide the NHS and personal hospitals with specific solutions. Historically, the most well-known brand name associated with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still used globally and informally in some UK theatres, the majority of the supply in the UK is now supplied by generic manufacturing specialists.
Table 1: Common Manufacturers and Product Details in the UK
| Producer | Item 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" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic versions, which are bioequivalent to the initial top quality product.
Medical Indications for Injection
Fentanyl citrate injection is utilized throughout various 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 used as an analgesic supplement throughout 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 may be administered in small, titrated boluses to manage 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 offer continuous analgesia for patients who are mechanically aerated. Its brief half-life permits more predictable "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 relocating to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To handle the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to boost discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising pain paths, altering the understanding of and response to discomfort. Fentanyl Citrate With Morphine UK increases the pain threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver by means of the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which discusses why the analgesic impact is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all potent opioids, fentanyl citrate brings a risk of significant side impacts, especially relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most severe threat; it decreases 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 ventilate quickly (generally accompanies high-dose rapid 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.
- Breathing anxiety in the lack 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).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to prevent 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 dose administered must be tape-recorded in a Controlled Drugs Register, signed by 2 certified healthcare professionals (usually a medical professional and a nurse, or 2 nurses).
- Disposal: Any wasted or unused portion of an ampoule must be experienced and damaged according to regional trust policy (generally utilizing a denaturing package).
FAQ: Fentanyl Citrate Injection in the UK
