Understanding Fentanyl Citrate Injection: Brand Names and Clinical Use in the UK
In the landscape of modern pain management and anesthesia, couple of medications are as powerful or as scientifically significant as fentanyl citrate. As a synthetic opioid analgesic, it plays an essential role in surgical settings and sharp pain management throughout the United Kingdom. Provided its high effectiveness-- estimated to be in between 50 and 100 times more effective than morphine-- comprehending its readily available types, brand, and regulatory status is essential for health care professionals and notified patients alike.
This article supplies a thorough introduction of fentanyl citrate injection within the UK healthcare system, detailing the brand names offered, its therapeutic indications, and the strict security procedures 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 main nerve system. When administered through injection (either intravenously or intramuscularly), it supplies extensive analgesia and sedation.
Unlike numerous naturally obtained opiates, fentanyl is extremely lipophilic (fat-soluble), which allows it to cross the blood-brain barrier quickly. This results in a rapid onset of action-- often within one to two minutes when administered intravenously-- making it a perfect option for intense surgical procedures and emergency 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 quickly soluble in water. By reacting learn more with citric acid to form fentanyl citrate, pharmaceutical manufacturers produce a stable, water-soluble service suitable for parenteral (injectable) administration.
Brand Name Names and Manufacturers in the UK
In the United Kingdom, fentanyl citrate injection is available both as a proprietary brand and as generic solutions. While the drug itself stays the exact same, the branding often depends on the particular pharmaceutical company providing the NHS (National Health Service) or personal medical facilities.
1. Sublimaze
Sublimaze is possibly the most traditionally recognized brand for fentanyl citrate injection. Initially established by Janssen Pharmaceutica, it ended up being the gold requirement for injectable fentanyl in clinical settings. While the name "Sublimaze" is still widely cited in medical literature, numerous UK medical facilities now primarily stock generic variations due to cost-effectiveness.
2. Generic Fentanyl Citrate
The bulk of fentanyl utilized in the UK is identified generically as "Fentanyl Citrate 50 micrograms/ml option for injection." Fentanyl Citrate Injection Brands UK of essential pharmaceutical business are accredited to disperse these generic variations in the UK.
Table 1: Common Suppliers and Brand Names in the UK
| Maker/ Brand Name | Type | Common 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 |
| Pfizer (Hospira) | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml ampoules |
| 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 pain; its usage is strictly reserved for specific scientific environments, such as operating theatres, intensive care systems (ICU), and emergency situation departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given quickly before surgery to cause sedation and relieve stress and anxiety.
- Analgesic Adjunct: Used along with unstable aesthetics (gases) or other intravenous agents to keep a "balanced anesthesia" state.
- Induction: Often utilized as part of the quick sequence induction to blunt the cardiovascular response to intubation.
2. Post-Operative Pain Management
For clients recovering from significant surgical treatment, little, titrated doses of fentanyl injection may be utilized in the healing room (PACU) to manage intense "development" discomfort that has not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is often administered by means of constant infusion to supply analgesia for patients who are mechanically ventilated. Its brief half-life allows clinicians to perform "sedation breaks" to assess the client's neurological status more successfully than with longer-acting opioids.
4. Palliative Care
In specialized terminal care settings, fentanyl injections might be utilized to manage extreme discomfort crises, although other routes (such as subcutaneous patches or sublingual tablets) are more common for chronic upkeep.
Dose and Administration Guidelines
The administration of fentanyl citrate injection should only be performed by qualified healthcare professionals (typically anesthetists or specialized nurses) who have access to resuscitative equipment.
Basic Strengths
The basic concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is available in different ampoule sizes, typically 2ml (containing 100mcg) and 10ml (including 500mcg).
Routes of Administration
- Intravenous (IV): The most typical route for an instant effect.
- Intramuscular (IM): Used when IV access is not offered, though the start is slower.
- Epidural/Intrathecal: Fentanyl is in some cases injected into the spine space to supply local anesthesia, often combined with a local anesthetic like bupivacaine.
Security, Contraindications, and Side Effects
Due to its severe strength, fentanyl citrate brings a considerable risk profile. The main concern is breathing depression, where the patient's drive to breathe is reduced.
Common Side Effects
- Queasiness and vomiting.
- Dizziness and sleepiness.
- Bradycardia (slow heart rate).
- Hypotension (low 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 become rigid, making ventilation difficult without making use of muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high potential 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 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. Moreover, under the Misuse of Drugs Regulations 2001, it is categorized as a Schedule 2 Controlled Drug.
This classification imposes stringent 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.
- Prescribing: Prescriptions should meet particular legal requirements regarding the total quantity and formula.
- Destruction: Any unused parts of an ampoule should be witnessed and destroyed according to health center protocols.
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
Q1: Is Sublimaze the like Fentanyl?
Yes. Sublimaze is merely the brand for the generic drug fentanyl citrate. In a lot of UK medical settings, the terms are utilized interchangeably, though the generic name is preferred in modern prescribing to avoid mistakes.
Q2: How fast does an injection of fentanyl work?
When provided intravenously, its impacts can be felt nearly instantly, peaking within 3 to 5 minutes. Its analgesic period is fairly brief, normally enduring 30 to 60 minutes.
Q3: Can fentanyl injection be used in your home?

Q4: What takes place if a patient is offered excessive fentanyl?
An overdose leads to extreme breathing depression, identify pupils, and loss of awareness. The standard "remedy" used 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 potent than morphine by weight. Fentanyl Citrate Injection UK means 100 micrograms (0.1 mg) of fentanyl is roughly comparable to 10mg of morphine.
Fentanyl citrate remains a foundation of the UK's acute treatment system. Whether branded as Sublimaze or offered as a generic formula from business like Accord or Hameln, its role in enabling complicated surgeries and managing extreme discomfort is vital.
