Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, widely recognized in scientific medicine for its fast start and brief duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial function in perioperative care, intensive care, and the management of severe, extreme pain. Due to the fact that of its potency-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and typically booked for healthcare facility settings.
For healthcare experts, students, or clients looking for to understand the medicinal landscape in the UK, recognizing the offered brand names and producers of fentanyl citrate injection is important. This post offers an extensive introduction of the brand name names, scientific signs, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that serves as a potent agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered through intravenous (IV) or intramuscular (IM) injection, it offers quick 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 main appeal in surgical settings is its capability to offer intense pain relief while preserving hemodynamic stability, making it a preferred choice for cardiac surgeries and for patients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical products are recommended by their generic name (Fentanyl) instead of a brand. Nevertheless, a number of manufacturers provide the NHS and personal hospitals with particular solutions. Historically, the most well-known trademark name related to fentanyl citrate was Sublimaze, originally developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized globally and colloquially in some UK theatres, the majority of the supply in the UK is now supplied by generic production professionals.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | 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 trademark 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 original top quality product.
Scientific Indications for Injection
Fentanyl citrate injection is used across different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is typically divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of modern anaesthesia. It is utilized as an analgesic supplement during the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "tension reaction" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, titrated boluses to handle 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 supply 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 transferring to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To handle the surgical discomfort stimulus throughout the treatment. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to enhance discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents rising discomfort pathways, changing the understanding of and response to pain. It likewise increases the discomfort threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Since fentanyl is highly lipid-soluble, it crosses the blood-brain barrier almost quickly, which describes why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Just like all powerful opioids, fentanyl citrate brings a threat of considerable side impacts, especially relating to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious risk; it minimizes the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to ventilate easily (generally accompanies high-dose fast IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory depression in the lack of resuscitative equipment.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat 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) cabinet that meets the British Standard for security.
- Record Keeping: Every dosage administered need to be tape-recorded in a Controlled Drugs Register, signed by two certified health care professionals (generally a doctor and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule should be witnessed and ruined according to local trust policy (usually using a denaturing package).
