Understanding Fentanyl Citrate Injection: Brand Names and Clinical Use in the UK
In the landscape of modern-day pain management and anesthesia, few medications are as potent or as medically significant as fentanyl citrate. As a synthetic opioid analgesic, it plays an essential function in surgical settings and severe pain management across the United Kingdom. Given its high potency-- estimated to be between 50 and 100 times more effective than morphine-- comprehending its available forms, brand names, and regulative status is essential for health care experts and notified patients alike.
This article provides a comprehensive introduction of fentanyl citrate injection within the UK health care system, detailing the trademark name offered, its therapeutic signs, and the stringent security protocols governing its use.
What is Fentanyl Citrate Injection?
Fentanyl citrate is a rapid-acting, short-duration opioid agonist that interacts primarily with the μ-opioid receptors in the central nerve system. When administered through injection (either intravenously or intramuscularly), it supplies extensive analgesia and sedation.
Unlike numerous naturally obtained opiates, fentanyl is highly lipophilic (fat-soluble), which allows it to cross the blood-brain barrier rapidly. This results in a rapid beginning of action-- often within one to 2 minutes when administered intravenously-- making it an ideal option for acute surgeries and emergency situation interventions.
The Significance of the "Citrate" Form
The "citrate" suffix refers to the salt form of the drug. Fentanyl in its base kind is not easily soluble in water. By responding Fentanyl Citrate UK with citric acid to form fentanyl citrate, pharmaceutical makers create a steady, water-soluble option suitable for parenteral (injectable) administration.
Trademark Name and Manufacturers in the UK
In the United Kingdom, fentanyl citrate injection is offered both as a proprietary brand and as generic formulas. While the drug itself stays the very same, the branding typically depends on the specific pharmaceutical company supplying the NHS (National Health Service) or private healthcare facilities.
1. Sublimaze
Sublimaze is possibly the most traditionally recognized brand name for fentanyl citrate injection. Initially developed by Janssen Pharmaceutica, it ended up being the gold requirement for injectable fentanyl in medical settings. While the name "Sublimaze" is still commonly pointed out in medical literature, lots of UK medical facilities now primarily stock generic versions due to cost-effectiveness.
2. Generic Fentanyl Citrate
Most of fentanyl utilized in the UK is labeled generically as "Fentanyl Citrate 50 micrograms/ml service for injection." Several crucial pharmaceutical companies are licensed to disperse these generic variations in the UK.
Table 1: Common Suppliers and Brand Names in the UK

| Wockhardt UK | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml ampoules |
Clinical Indications for Injection
Fentanyl citrate injection is not a basic ward medication for mild discomfort; its use is strictly scheduled for specific scientific environments, such as running theatres, extensive care systems (ICU), and emergency situation departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given quickly before surgical treatment to induce sedation and alleviate stress and anxiety.
- Analgesic Adjunct: Used along with unstable looks (gases) or other intravenous representatives to keep a "well balanced anesthesia" state.
- Induction: Often utilized as part of the rapid sequence induction to blunt the cardiovascular action to intubation.
2. Post-Operative Pain Management
For clients recuperating from major surgical treatment, small, titrated dosages of fentanyl injection might be utilized in the recovery room (PACU) to manage intense "breakthrough" discomfort that has not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is frequently administered by means of continuous infusion to supply analgesia for patients who are mechanically aerated. Its brief half-life permits clinicians to perform "sedation breaks" to evaluate the client's neurological status more efficiently than with longer-acting opioids.
4. Palliative Care
In specific terminal care settings, fentanyl injections may be used to manage severe pain crises, although other routes (such as subcutaneous spots or sublingual tablets) are more typical for chronic maintenance.
Dosage and Administration Guidelines
The administration of fentanyl citrate injection must just be performed by skilled health care specialists (generally anesthetists or specialized nurses) who have access to resuscitative devices.
Basic Strengths
The basic concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is available in different ampoule sizes, normally 2ml (including 100mcg) and 10ml (including 500mcg).
Paths of Administration
- Intravenous (IV): The most typical route for an instant impact.
- Intramuscular (IM): Used when IV access is not available, though the start is slower.
- Epidural/Intrathecal: Fentanyl is often injected into the back space to offer local anesthesia, frequently integrated with an anesthetic like bupivacaine.
Security, Contraindications, and Side Effects
Due to its extreme strength, fentanyl citrate carries a substantial danger profile. The main concern is respiratory anxiety, where the client's drive to breathe is reduced.
Typical Side Effects
- Nausea and throwing up.
- Lightheadedness and drowsiness.
- Bradycardia (sluggish heart rate).
- Hypotension (low high blood pressure).
- Urinary retention.
Severe Risks
- Chest Wall Rigidity: Rapid IV infusion of high-dose fentanyl can trigger "Stiff Person Syndrome" or "Woody Chest," where the skeletal muscles of the chest and abdomen end up being rigid, making ventilation difficult without using muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high capacity for reliance.
- Cross-Reactivity: It must be used with severe care in patients who have taken Monoamine Oxidase Inhibitors (MAOIs) within the previous 14 days, as this can set off a hypertensive crisis or serotonin syndrome.
Legal Status and Controls in the UK
In the United Kingdom, fentanyl is classified under the Misuse of Drugs Act 1971 as a Class A drug. Additionally, under the Misuse of Drugs Regulations 2001, it is categorized as a Schedule 2 Controlled Drug.
This category imposes stringent requirements on:
- Storage: Must be kept in a double-locked "CD" (Controlled Drug) cupboard.
- Record Keeping: Every milligram should be accounted for in a Controlled Drugs Register.
- Prescribing: Prescriptions must fulfill particular legal requirements regarding the total quantity and formulation.
- Destruction: Any unused parts of an ampoule should be witnessed and destroyed according to hospital procedures.
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
Q1: Is Sublimaze the like Fentanyl?
Yes. Sublimaze is simply the trademark name for the generic drug fentanyl citrate. In most UK clinical settings, the terms are utilized interchangeably, though the generic name is preferred in modern-day recommending to avoid mistakes.
Q2: How quick does an injection of fentanyl work?
When provided intravenously, its effects can be felt almost immediately, peaking within 3 to 5 minutes. Its analgesic duration is fairly short, generally lasting 30 to 60 minutes.
Q3: Can fentanyl injection be used in the house?
No. Fentanyl citrate injection is strictly an "in-hospital" medication. For home usage (e.g., in palliative care), fentanyl is typically recommended as transdermal spots (e.g., Duragesic or Matrifen) or as lozenges/nasal sprays for breakthrough pain.
Q4: What happens if a patient is offered too much fentanyl?
An overdose leads to serious breathing depression, identify students, and loss of awareness. The standard "remedy" utilized in the UK is Naloxone, a competitive opioid antagonist that reverses the results of fentanyl.
Q5: Is fentanyl citrate injection more powerful than morphine?
Yes, significantly. Fentanyl is roughly 80 to 100 times more potent than morphine by weight. This implies 100 micrograms (0.1 mg) of fentanyl is roughly comparable to 10mg of morphine.
Fentanyl citrate stays a foundation of the UK's intense treatment system. Whether branded as Sublimaze or provided as a generic formulation from business like Accord or Hameln, its role in allowing intricate surgeries and handling severe discomfort is indispensable. However, its potency requires a high level of caution, stringent legal controls, and specialist administration.
