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 clinically substantial as fentanyl citrate. As a synthetic opioid analgesic, it plays an important role in surgical settings and severe discomfort management across the United Kingdom. Given its high potency-- approximated to be in between 50 and 100 times more powerful than morphine-- understanding its available kinds, brand name names, and regulative status is vital for health care specialists and notified patients alike.
This article provides a detailed summary of fentanyl citrate injection within the UK healthcare system, detailing the trademark name available, its healing indications, and the rigorous safety protocols governing its use.
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 central nerve system. When administered by means of injection (either intravenously or intramuscularly), it provides extensive analgesia and sedation.
Unlike numerous naturally obtained opiates, fentanyl is extremely lipophilic (fat-soluble), which permits it to cross the blood-brain barrier rapidly. This results in a fast start of action-- often within one to 2 minutes when administered intravenously-- making it an ideal choice for intense surgical treatments and emergency interventions.
The Significance of the "Citrate" Form
The "citrate" suffix refers to the salt kind of the drug. Fentanyl in its base kind is not quickly soluble in water. By responding it with citric acid to form fentanyl citrate, pharmaceutical makers create a steady, water-soluble solution suitable for parenteral (injectable) administration.
Brand Names and Manufacturers in the UK
In the United Kingdom, fentanyl citrate injection is readily available both as an exclusive brand name and as generic solutions. While the drug itself remains the same, the branding frequently depends on the specific pharmaceutical company supplying the NHS (National Health Service) or personal hospitals.
1. Sublimaze
Sublimaze is maybe the most historically recognized trademark name for fentanyl citrate injection. Initially established by Janssen Pharmaceutica, it ended up being the gold standard for injectable fentanyl in medical settings. While the name "Sublimaze" is still commonly mentioned in medical literature, lots of UK health centers now primarily stock generic versions due to cost-effectiveness.
2. Generic Fentanyl Citrate
Most of fentanyl used in the UK is identified generically as "Fentanyl Citrate 50 micrograms/ml option for injection." Several crucial pharmaceutical companies are licensed to distribute these generic variations in the UK.
Table 1: Common Suppliers and Brand Names in the UK
| Maker/ Brand Name | Kind | Common Strengths | Common 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 |

| Wockhardt UK | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml ampoules |
Scientific Indications for Injection
Fentanyl citrate injection is not a standard ward medication for moderate discomfort; its use is strictly reserved for specific scientific environments, such as operating theatres, extensive care systems (ICU), and emergency situation departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given soon before surgery to cause sedation and alleviate stress and anxiety.
- Analgesic Adjunct: Used alongside volatile looks (gases) or other intravenous representatives to keep a "well balanced anesthesia" state.
- Induction: Often utilized as part of the quick sequence induction to blunt the cardiovascular action to intubation.
2. Post-Operative Pain Management
For clients recuperating from significant surgical treatment, little, titrated dosages of fentanyl injection may be utilized in the healing room (PACU) to manage severe "advancement" discomfort that has not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is regularly administered via constant infusion to offer analgesia for clients who are mechanically aerated. Its brief half-life allows clinicians to carry out "sedation breaks" to examine the patient's neurological status more effectively than with longer-acting opioids.
4. Palliative Care
In specialized terminal care settings, fentanyl injections may be utilized to handle severe discomfort crises, although other paths (such as subcutaneous patches or sublingual tablets) are more typical for persistent upkeep.
Dosage and Administration Guidelines
The administration of fentanyl citrate injection need to only be performed by qualified healthcare specialists (usually anesthetists or specialized nurses) who have access to resuscitative equipment.
Standard Strengths
The standard concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is available in various ampoule sizes, usually 2ml (consisting of 100mcg) and 10ml (containing 500mcg).
Routes of Administration
- Intravenous (IV): The most common route for an instant impact.
- Intramuscular (IM): Used when IV gain access to 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, typically combined with a local anesthetic like bupivacaine.
Security, Contraindications, and Side Effects
Due to its severe effectiveness, fentanyl citrate brings a substantial threat profile. The main concern is breathing anxiety, where the client's drive to breathe is decreased.
Common Side Effects
- Nausea and vomiting.
- Lightheadedness and drowsiness.
- Bradycardia (slow heart rate).
- Hypotension (low high blood pressure).
- Urinary retention.
Severe 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 rigid, making ventilation impossible without using muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high capacity for reliance.
- Cross-Reactivity: It needs to be used with extreme caution in patients who have taken Monoamine Oxidase Inhibitors (MAOIs) within the previous 14 days, as this can trigger a hypertensive crisis or serotonin syndrome.
Legal Status and Controls in the UK
In the United Kingdom, fentanyl is categorized 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 classification enforces rigorous requirements on:
- Storage: Must be kept in a double-locked "CD" (Controlled Drug) cupboard.
- Record Keeping: Every milligram needs to be represented in a Controlled Drugs Register.
- Recommending: Prescriptions must fulfill particular legal requirements regarding the total quantity and formulation.
- Damage: Any unused portions of an ampoule must be experienced and damaged according to hospital protocols.
FAQ: Fentanyl Citrate Injection in the UK
Q1: Is Sublimaze the same as Fentanyl?
Yes. visit website is merely the trademark name for the generic drug fentanyl citrate. In the majority of UK scientific settings, the terms are used interchangeably, though the generic name is preferred in modern recommending to avoid errors.
Q2: How quick does an injection of fentanyl work?
When offered intravenously, its impacts can be felt practically instantly, peaking within 3 to 5 minutes. Its analgesic period is relatively brief, typically lasting 30 to 60 minutes.

No. Fentanyl citrate injection is strictly an "in-hospital" medication. For home use (e.g., in palliative care), fentanyl is generally recommended as transdermal patches (e.g., Duragesic or Matrifen) or as lozenges/nasal sprays for advancement discomfort.
Q4: What takes place if a client is offered excessive fentanyl?
An overdose causes severe breathing depression, determine students, and loss of consciousness. The basic "remedy" utilized in the UK is Naloxone, a competitive opioid villain that reverses the results of fentanyl.
Q5: Is fentanyl citrate injection more powerful than morphine?
Yes, substantially. Fentanyl is approximately 80 to 100 times more potent than morphine by weight. This means 100 micrograms (0.1 mg) of fentanyl is approximately equivalent to 10mg of morphine.
