Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, commonly recognized in scientific medication for its quick beginning and brief duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial function in perioperative care, extensive care, and the management of acute, extreme pain. Since of its strength-- approximated to be 50 to 100 times that of morphine-- its administration via injection is strictly controlled and typically reserved for healthcare facility settings.
For healthcare professionals, students, or patients looking for to comprehend the medicinal landscape in the UK, identifying the offered trademark name and producers of fentanyl citrate injection is essential. This blog site post offers a thorough overview of the brand, clinical 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 worried system. When administered via Fentanyl Citrate Indications UK (IV) or intramuscular (IM) injection, it provides fast 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 provide intense pain relief while maintaining hemodynamic stability, making it a favored choice for heart 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 prescribed by their generic name (Fentanyl) instead of a brand. However, a number of producers provide the NHS and personal hospitals with specific formulations. Historically, the most well-known brand name related to fentanyl citrate was Sublimaze, initially established 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 supplied by generic manufacturing specialists.
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 |

While the brand "Sublimaze" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic variations, which are bioequivalent to the initial top quality product.
Medical Indications for Injection
Fentanyl citrate injection is made use of across numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into 3 classifications:
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 assists blunt the body's physiological "stress action" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in little, titrated boluses to manage instant post-surgical pain before shifts 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 constant analgesia for patients who are mechanically aerated. Its brief half-life enables for more predictable "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 agents (like Propofol) for a smooth shift to unconsciousness. |
| Maintenance | To handle the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending pain paths, altering the perception of and reaction to discomfort. It also increases the pain threshold.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Due to the fact that fentanyl is highly lipid-soluble, it crosses the blood-brain barrier nearly quickly, which discusses why the analgesic impact is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Just like all potent opioids, fentanyl citrate brings a threat of substantial side impacts, especially relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious risk; it decreases the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to aerate easily (usually accompanies high-dose quick 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 absence of resuscitative devices.
- Concurrent usage 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 should be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dosage administered should be taped in a Controlled Drugs Register, signed by two qualified health care experts (typically a medical professional and a nurse, or more nurses).
- Disposal: Any wasted or unused part of an ampoule need to be seen and ruined according to local trust policy (normally utilizing a denaturing package).
