Understanding Fentanyl Citrate Injection: Brand Names and Clinical Use in the UK
In the landscape of contemporary discomfort management and anesthesia, few medications are as powerful or as clinically considerable as fentanyl citrate. As an artificial opioid analgesic, it plays an important role in surgical settings and acute pain management throughout the United Kingdom. Offered its high strength-- approximated to be between 50 and 100 times more powerful than morphine-- comprehending its available kinds, brand, and regulatory status is necessary for health care professionals and informed patients alike.
This short article supplies a comprehensive introduction of fentanyl citrate injection within the UK health care system, detailing the trademark name available, its healing indications, and the stringent safety procedures governing its use.
What is Fentanyl Citrate Injection?
Fentanyl citrate is a rapid-acting, short-duration opioid agonist that engages mostly with the μ-opioid receptors in the central nerve system. When administered by Medic Store GB of injection (either intravenously or intramuscularly), it offers profound analgesia and sedation.
Unlike many naturally obtained opiates, fentanyl is extremely lipophilic (fat-soluble), which enables it to cross the blood-brain barrier rapidly. This leads to a fast start of action-- typically within one to two minutes when administered intravenously-- making it an ideal choice for severe surgical treatments and emergency situation interventions.
The Significance of the "Citrate" Form
The "citrate" suffix describes the salt kind of the drug. Fentanyl in its base type is not quickly soluble in water. By reacting 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 available both as a proprietary brand and as generic formulas. While the drug itself remains the same, the branding frequently depends on the particular pharmaceutical business providing the NHS (National Health Service) or private health centers.
1. Sublimaze
Sublimaze is possibly the most historically acknowledged brand for fentanyl citrate injection. Initially established by Janssen Pharmaceutica, it became the gold requirement for injectable fentanyl in clinical settings. While the name "Sublimaze" is still commonly mentioned in medical literature, lots of UK healthcare facilities now mostly stock generic versions due to cost-effectiveness.
2. Generic Fentanyl Citrate
Most of fentanyl used in the UK is labeled generically as "Fentanyl Citrate 50 micrograms/ml solution for injection." Numerous key pharmaceutical business are accredited to distribute these generic versions in the UK.
Table 1: Common Suppliers and Brand Names in the UK

| Sublimaze (Janssen-Cilag) | Solution for Injection | 50 mcg/ml | 2ml, 10ml ampoules |
| Accord Healthcare | Fentanyl Citrate (Generic) | 50 mcg/ml | 2ml, 10ml ampoules |

Scientific Indications for Injection
Fentanyl citrate injection is not a basic ward medication for moderate discomfort; its usage is strictly scheduled for particular clinical environments, such as operating theatres, extensive care units (ICU), and emergency situation departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given soon before surgery to cause sedation and ease anxiety.
- Analgesic Adjunct: Used along with volatile aesthetic appeals (gases) or other intravenous representatives to keep a "well balanced anesthesia" state.
- Induction: Often used as part of the fast series induction to blunt the cardiovascular reaction to intubation.
2. Post-Operative Pain Management
For clients recuperating from major surgical treatment, little, titrated dosages of fentanyl injection might be used in the recovery room (PACU) to handle severe "development" discomfort that has actually not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is regularly administered by means of constant infusion to supply analgesia for clients who are mechanically aerated. Its brief half-life allows clinicians to perform "sedation breaks" to assess the patient's neurological status better than with longer-acting opioids.
4. Palliative Care
In specialized terminal care settings, fentanyl injections may be used to manage serious discomfort crises, although other routes (such as subcutaneous spots or sublingual tablets) are more typical for chronic maintenance.
Dose and Administration Guidelines
The administration of fentanyl citrate injection must just be performed by trained health care experts (usually anesthetists or specialized nurses) who have access to resuscitative devices.
Standard Strengths
The basic concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is readily available in various ampoule sizes, generally 2ml (including 100mcg) and 10ml (consisting of 500mcg).
Routes 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 sometimes injected into the spinal area to offer local anesthesia, typically integrated with a regional anesthetic like bupivacaine.
Safety, Contraindications, and Side Effects
Due to its extreme strength, fentanyl citrate carries a considerable risk profile. The primary concern is breathing depression, where the patient's drive to breathe is lessened.
Typical Side Effects
- Nausea and vomiting.
- Lightheadedness and drowsiness.
- Bradycardia (slow heart rate).
- Hypotension (low blood pressure).
- Urinary retention.
Serious 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 abdominal area end up being stiff, making ventilation difficult without the use of muscle relaxants.
- Dependency and Misuse: Like all opioids, fentanyl has a high capacity for dependence.
- Cross-Reactivity: It must be utilized with extreme care in clients who have actually 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. In addition, under the Misuse of Drugs Regulations 2001, it is classified as a Schedule 2 Controlled Drug.
This classification enforces strict 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.
- Prescribing: Prescriptions need to meet specific legal requirements concerning the overall quantity and formulation.
- Damage: Any unused portions of an ampoule should be seen and ruined according to hospital procedures.
FREQUENTLY ASKED QUESTION: Fentanyl Citrate Injection in the UK
Q1: Is Sublimaze the exact same as Fentanyl?
Yes. Sublimaze is just the trademark name for the generic drug fentanyl citrate. In many UK scientific settings, the terms are used interchangeably, though the generic name is chosen in contemporary recommending to prevent errors.
Q2: How fast does an injection of fentanyl work?
When provided intravenously, its effects can be felt almost right away, peaking within 3 to 5 minutes. Its analgesic period is relatively brief, typically long lasting 30 to 60 minutes.
Q3: Can fentanyl injection be utilized in your home?
No. Fentanyl citrate injection is strictly an "in-hospital" medication. For home use (e.g., in palliative care), fentanyl is normally recommended as transdermal patches (e.g., Duragesic or Matrifen) or as lozenges/nasal sprays for breakthrough pain.
Q4: What takes place if a client is provided excessive fentanyl?
An overdose leads to severe breathing anxiety, identify students, and loss of consciousness. The basic "remedy" utilized in the UK is Naloxone, a competitive opioid villain that reverses the effects of fentanyl.
Q5: Is fentanyl citrate injection stronger than morphine?
Yes, significantly. Fentanyl is roughly 80 to 100 times more potent than morphine by weight. This means 100 micrograms (0.1 mg) of fentanyl is approximately comparable to 10mg of morphine.
Fentanyl citrate remains a foundation of the UK's severe treatment system. Whether branded as Sublimaze or supplied as a generic formulation from business like Accord or Hameln, its role in making it possible for complex surgical treatments and handling severe discomfort is vital. However, its strength demands a high level of alertness, stringent legal controls, and expert administration. By understanding the brand names and the medicinal profile of this effective opioid, healthcare providers can ensure it is used safely and efficiently to improve client results.
