Understanding Fentanyl Citrate Injection: Brand Names and Clinical Use in the UK
In the landscape of modern-day pain management and anesthesia, couple of medications are as powerful or as scientifically considerable as fentanyl citrate. As an artificial opioid analgesic, it plays a crucial role in surgical settings and severe pain management across the United Kingdom. Given its high effectiveness-- approximated to be between 50 and 100 times more powerful than morphine-- understanding its offered types, brand, and regulatory status is important for healthcare specialists and informed patients alike.
This article offers a comprehensive overview of fentanyl citrate injection within the UK health care system, detailing the trademark name readily available, its restorative signs, and the rigorous security procedures governing its usage.
What is Fentanyl Citrate Injection?
Fentanyl citrate is a rapid-acting, short-duration opioid agonist that connects primarily with the μ-opioid receptors in the main nerve system. When administered by means of injection (either intravenously or intramuscularly), it provides extensive analgesia and sedation.
Unlike many naturally derived opiates, fentanyl is highly lipophilic (fat-soluble), which enables it to cross the blood-brain barrier quickly. This leads to a quick start of action-- typically within one to two minutes when administered intravenously-- making it a perfect choice for severe surgical procedures and emergency situation interventions.
The Significance of the "Citrate" Form
The "citrate" suffix refers to the salt type of the drug. Fentanyl in its base form is not quickly soluble in water. By responding it with citric acid to form fentanyl citrate, pharmaceutical producers create a stable, water-soluble option ideal 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 formulations. While the drug itself stays the exact same, the branding often depends upon the particular pharmaceutical company supplying the NHS (National Health Service) or personal hospitals.
1. Sublimaze
Sublimaze is maybe the most traditionally acknowledged brand for fentanyl citrate injection. Originally developed by Janssen Pharmaceutica, it ended up being the gold standard for injectable fentanyl in clinical settings. While the name "Sublimaze" is still commonly mentioned in medical literature, many UK healthcare facilities now primarily stock generic variations due to cost-effectiveness.
2. Generic Fentanyl Citrate
Most of fentanyl utilized in the UK is labeled generically as "Fentanyl Citrate 50 micrograms/ml option for injection." A number of essential pharmaceutical companies are licensed to distribute these generic versions in the UK.
Table 1: Common Suppliers and Brand Names in the UK
| Producer/ Brand Name | Type | Typical Strengths | Typical Pack Sizes |
|---|---|---|---|
| Sublimaze (Janssen-Cilag) | Solution for Injection | 50 mcg/ml | 2ml, 10ml ampoules |
| Accord Healthcare | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml ampoules |
| Hameln Pharmaceuticals | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml, 20ml ampoules |

Scientific Indications for Injection
Fentanyl citrate injection is not a basic ward medication for mild pain; its usage is strictly scheduled for particular medical environments, such as running theatres, extensive care systems (ICU), and emergency situation departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given shortly before surgical treatment to cause sedation and eliminate stress and anxiety.
- Analgesic Adjunct: Used along with unpredictable aesthetic appeals (gases) or other intravenous agents to maintain a "balanced anesthesia" state.
- Induction: Often used as part of the fast series induction to blunt the cardiovascular action to intubation.
2. Post-Operative Pain Management
For clients recovering from major surgery, small, titrated doses of fentanyl injection may be utilized in the healing space (PACU) to manage acute "breakthrough" discomfort that has actually not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is often administered via continuous infusion to offer analgesia for patients who are mechanically ventilated. Its brief half-life enables clinicians to perform "sedation breaks" to evaluate the patient's neurological status better than with longer-acting opioids.
4. Palliative Care
In customized terminal care settings, fentanyl injections might be used to handle serious discomfort crises, although other routes (such as subcutaneous spots or sublingual tablets) are more common for persistent upkeep.
Dose and Administration Guidelines
The administration of fentanyl citrate injection should only be carried out by qualified health care experts (normally anesthetists or specialized nurses) who have access to resuscitative equipment.
Basic Strengths
The standard concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is readily available in numerous ampoule sizes, generally 2ml (including 100mcg) and 10ml (containing 500mcg).
Routes of Administration
- Intravenous (IV): The most typical path for an instant result.
- Intramuscular (IM): Used when IV access is not readily available, though the start is slower.
- Epidural/Intrathecal: Fentanyl is in some cases injected into the back space to supply local anesthesia, frequently integrated with a local anesthetic like bupivacaine.
Safety, Contraindications, and Side Effects
Due to its severe effectiveness, fentanyl citrate brings a considerable risk profile. The main issue is breathing depression, where the client's drive to breathe is decreased.
Typical Side Effects
- Queasiness and throwing up.
- Dizziness and sleepiness.
- Bradycardia (sluggish heart rate).
- Hypotension (low blood pressure).
- Urinary retention.
Major Risks
- Chest Wall Rigidity: Rapid IV infusion of high-dose fentanyl can cause "Stiff Person Syndrome" or "Woody Chest," where the skeletal muscles of the chest and abdomen end up being stiff, making ventilation impossible without the usage of muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high capacity for dependence.
- Cross-Reactivity: It should be utilized with severe caution in clients who have actually taken Monoamine Oxidase Inhibitors (MAOIs) within the previous 14 days, as this can activate 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. Moreover, under the Misuse of Drugs Regulations 2001, it is categorized as a Schedule 2 Controlled Drug.
This classification enforces rigorous requirements on:
- Storage: Must be kept in a double-locked "CD" (Controlled Drug) cupboard.
- Record Keeping: Every milligram should be represented in a Controlled Drugs Register.
- Recommending: Prescriptions should satisfy particular legal requirements relating to the overall amount and formula.
- Damage: Any unused portions of an ampoule need to be experienced and damaged according to healthcare facility procedures.
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
Q1: Is Sublimaze the same as Fentanyl?
Yes. Sublimaze is simply the trademark name for the generic drug fentanyl citrate. In many UK scientific settings, the terms are utilized interchangeably, though the generic name is chosen in modern-day recommending to avoid errors.
Q2: How quick does an injection of fentanyl work?
When provided intravenously, its impacts can be felt practically immediately, peaking within 3 to 5 minutes. Its analgesic period is fairly short, generally long lasting 30 to 60 minutes.
Q3: Can fentanyl injection be used at home?
No. Fentanyl citrate injection is strictly an "in-hospital" medication. For home usage (e.g., in palliative care), fentanyl is usually prescribed as transdermal patches (e.g., Duragesic or Matrifen) or as lozenges/nasal sprays for advancement pain.
Q4: What takes place if a patient is given excessive fentanyl?
An overdose leads to extreme breathing anxiety, identify students, and loss of consciousness. The standard "antidote" utilized in the UK is Naloxone, a competitive opioid antagonist that reverses the effects of fentanyl.
Q5: Is fentanyl citrate injection stronger than morphine?
Yes, considerably. Fentanyl is roughly 80 to 100 times more powerful than morphine by weight. This indicates 100 micrograms (0.1 mg) of fentanyl is approximately equivalent to 10mg of morphine.
Fentanyl citrate stays a foundation of the UK's severe medical care system.
