Understanding Fentanyl Citrate Injection: Brand Names and Clinical Use in the UK
In the landscape of modern-day discomfort management and anesthesia, couple of medications are as potent or as scientifically substantial as fentanyl citrate. As a synthetic opioid analgesic, it plays an essential role in surgical settings and acute pain management throughout the United Kingdom. Given learn more -- estimated to be in between 50 and 100 times more effective than morphine-- understanding its readily available types, brand name names, and regulatory status is necessary for healthcare professionals and informed patients alike.
This short article offers a thorough introduction of fentanyl citrate injection within the UK healthcare system, detailing the trademark name available, its healing indications, and the stringent security procedures governing its usage.
What is Fentanyl Citrate Injection?
Fentanyl citrate is a rapid-acting, short-duration opioid agonist that communicates primarily with the μ-opioid receptors in the central nerve system. When administered through injection (either intravenously or intramuscularly), it offers extensive analgesia and sedation.
Unlike lots of naturally obtained opiates, fentanyl is extremely lipophilic (fat-soluble), which allows it to cross the blood-brain barrier quickly. This leads to a rapid onset of action-- frequently within one to two minutes when administered intravenously-- making it a perfect option 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 form is not quickly soluble in water. By responding it with citric acid to form fentanyl citrate, pharmaceutical producers produce a stable, water-soluble option suitable for parenteral (injectable) administration.
Trademark Name and Manufacturers in the UK
In the United Kingdom, fentanyl citrate injection is available both as an exclusive brand and as generic formulations. While the drug itself stays the same, the branding often depends upon the particular pharmaceutical business providing the NHS (National Health Service) or private healthcare facilities.
1. Sublimaze
Sublimaze is perhaps the most historically acknowledged brand for fentanyl citrate injection. Originally established by Janssen Pharmaceutica, it became the gold standard for injectable fentanyl in clinical settings. While the name "Sublimaze" is still widely cited in medical literature, numerous UK hospitals now mostly stock generic versions due to cost-effectiveness.
2. Generic Fentanyl Citrate
Most of fentanyl utilized in the UK is identified generically as "Fentanyl Citrate 50 micrograms/ml option for injection." Several essential pharmaceutical companies are licensed to disperse these generic versions in the UK.
Table 1: Common Suppliers and Brand Names in the UK
| Manufacturer/ Brand Name | Kind | 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 |

Clinical Indications for Injection
Fentanyl citrate injection is not a basic ward medication for mild discomfort; its use is strictly reserved for particular clinical environments, such as operating theatres, intensive care units (ICU), and emergency departments.
1. Anesthesia and Surgical Support
- Pre-medication: Given quickly before surgical treatment to cause sedation and relieve stress and anxiety.
- Analgesic Adjunct: Used along with volatile visual appeals (gases) or other intravenous representatives to maintain a "well balanced anesthesia" state.
- Induction: Often utilized as part of the fast series induction to blunt the cardiovascular action to intubation.
2. Post-Operative Pain Management
For patients recuperating from significant surgical treatment, little, titrated dosages of fentanyl injection might be utilized in the recovery room (PACU) to handle severe "development" discomfort that has actually not responded to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is often administered by means of constant infusion to provide analgesia for clients who are mechanically ventilated. Its brief half-life enables clinicians to perform "sedation breaks" to examine the client's neurological status more effectively than with longer-acting opioids.
4. Palliative Care
In specific terminal care settings, fentanyl injections may be utilized to handle severe pain crises, although other routes (such as subcutaneous patches or sublingual tablets) are more common for persistent maintenance.
Dosage and Administration Guidelines
The administration of fentanyl citrate injection need to just be performed by trained health care professionals (generally anesthetists or specialized nurses) who have access to resuscitative devices.
Basic Strengths
The standard concentration in the UK is 50 micrograms per milliliter (50mcg/ml). It is offered in different ampoule sizes, normally 2ml (including 100mcg) and 10ml (including 500mcg).
Paths of Administration
- Intravenous (IV): The most typical route for an immediate impact.
- Intramuscular (IM): Used when IV access is not available, though the onset is slower.
- Epidural/Intrathecal: Fentanyl is in some cases injected into the spinal area to provide regional anesthesia, typically combined with an anesthetic like bupivacaine.
Safety, Contraindications, and Side Effects
Due to its extreme strength, fentanyl citrate carries a significant risk profile. The primary issue is breathing depression, where the patient's drive to breathe is decreased.
Typical Side Effects
- Queasiness and throwing up.
- Dizziness 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 become rigid, making ventilation difficult without making use of muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high capacity for reliance.
- Cross-Reactivity: It should be used with severe care in patients who have actually 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 classified under the Misuse of Drugs Act 1971 as a Class A drug. Additionally, under the Misuse of Drugs Regulations 2001, it is classified as a Schedule 2 Controlled Drug.
This category enforces strict requirements on:
- Storage: Must be kept in a double-locked "CD" (Controlled Drug) cabinet.
- Record Keeping: Every milligram should be accounted for in a Controlled Drugs Register.
- Prescribing: Prescriptions need to satisfy particular legal requirements regarding the overall amount and formula.
- Damage: Any unused parts of an ampoule should be seen and ruined according to medical facility protocols.
