Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent artificial opioid analgesic, commonly acknowledged in clinical medicine for its quick start and brief duration of action. Within the United Kingdom's health care system, fentanyl plays an important role in perioperative care, intensive care, and the management of acute, extreme discomfort. Since of its effectiveness-- approximated to be 50 to 100 times that of morphine-- its administration via injection is strictly managed and normally reserved for health center settings.
For health care experts, trainees, or patients seeking to understand the medicinal landscape in the UK, identifying the readily available brand names and makers of fentanyl citrate injection is necessary. This blog site post supplies a comprehensive introduction of the trademark name, scientific indicators, 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered via 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 capability to supply extreme pain relief while keeping hemodynamic stability, making it a favored choice for heart surgical treatments and for clients with vulnerable cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are recommended by their generic name (Fentanyl) rather than a trademark name. However, a number of producers supply the NHS and private medical facilities with specific formulas. Historically, the most famous trademark name related to fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While visit website is still utilized internationally and colloquially in some UK theatres, the bulk of the supply in the UK is now supplied by generic production 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) |

While the trademark name "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 original top quality product.
Scientific Indications for Injection
Fentanyl citrate injection is utilized across various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into three categories:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It helps blunt the body's physiological "stress reaction" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle immediate post-surgical discomfort before shifts are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is often used as an infusion to supply continuous analgesia for clients who are mechanically aerated. Its short half-life enables 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 comply with induction agents (like Propofol) for a smooth shift to unconsciousness. |
| Upkeep | To manage the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in regional anaesthesia (like epidurals) to improve discomfort relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising discomfort paths, changing the perception of and action to pain. 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).
- 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 practically quickly, which discusses why the analgesic effect is felt so much faster than with morphine or oxycodone.
Safety and Side Effects
Similar to all potent opioids, fentanyl citrate carries a risk of significant adverse effects, particularly connecting to the breathing 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 ends up being too stiff to ventilate quickly (generally accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently 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 usage 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 avoid diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered must be taped in a Controlled Drugs Register, signed by 2 certified health care specialists (usually a doctor and a nurse, or two nurses).
- Disposal: Any lost or unused portion of an ampoule must be witnessed and ruined according to regional trust policy (generally using a denaturing kit).
