What is Fentanyl Citrate Injection?
Fentanyl citrate is a rapid-acting, short-duration opioid agonist that interacts primarily with the μ-opioid receptors in the main nerve system. When administered through injection (either intravenously or intramuscularly), it offers extensive analgesia and sedation.
Unlike numerous naturally derived opiates, fentanyl is highly lipophilic (fat-soluble), which allows it to cross the blood-brain barrier quickly. This results in a quick onset of action-- typically within one to 2 minutes when administered intravenously-- making it a perfect option for intense surgeries and emergency interventions.
The Significance of the "Citrate" Form
The "citrate" suffix describes the salt type of the drug. Fentanyl in its base type is not quickly soluble in water. By responding it with citric acid to form fentanyl citrate, pharmaceutical producers produce a steady, water-soluble solution ideal 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 name and as generic formulas. While the drug itself remains the very same, the branding typically depends upon the particular pharmaceutical company supplying the NHS (National Health Service) or personal medical facilities.
1. Sublimaze
Sublimaze is possibly the most traditionally acknowledged brand 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 widely pointed out in medical literature, numerous UK health centers now mainly 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 option for injection." Numerous essential pharmaceutical companies are certified to distribute these generic variations in the UK.

1. Anesthesia and Surgical Support
- Pre-medication: Given quickly before surgery to cause sedation and ease anxiety.
- Analgesic Adjunct: Used along with unstable visual appeals (gases) or other intravenous representatives to keep a "well balanced anesthesia" state.
- Induction: Often used as part of the quick series induction to blunt the cardiovascular response to intubation.
2. Post-Operative Pain Management
For patients recuperating from significant surgery, small, titrated dosages of fentanyl injection may be used in the recovery room (PACU) to manage intense "development" pain that has actually not reacted to other medications.
3. Intensive Care Sedation
In the ICU, fentanyl is often administered by means of continuous infusion to supply analgesia for clients who are mechanically aerated. Its short half-life allows clinicians to perform "sedation breaks" to examine the client's neurological status more efficiently than with longer-acting opioids.
4. Palliative Care
In customized terminal care settings, fentanyl injections may be utilized to handle extreme discomfort crises, although other routes (such as subcutaneous spots or sublingual tablets) are more typical for chronic maintenance.
Dosage and Administration Guidelines
The administration of fentanyl citrate injection must just be performed by trained healthcare specialists (normally 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 offered in various ampoule sizes, normally 2ml (including 100mcg) and 10ml (including 500mcg).
Paths of Administration
- Intravenous (IV): The most common path for an immediate effect.
- Intramuscular (IM): Used when IV access is not readily available, though the start is slower.
- Epidural/Intrathecal: Fentanyl is sometimes injected into the back area to offer regional anesthesia, typically combined with a regional anesthetic like bupivacaine.
Safety, Contraindications, and Side Effects
Due to its severe effectiveness, fentanyl citrate brings a substantial risk profile. The primary issue is breathing anxiety, where the client's drive to breathe is reduced.
Common Side Effects
- Nausea and vomiting.
- Dizziness and drowsiness.
- Bradycardia (slow heart rate).
- Hypotension (low blood pressure).
- Urinary retention.
Severe Risks
- Chest Wall Rigidity: Rapid IV infusion of high-dose fentanyl can trigger "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 usage of muscle relaxants.
- Addiction and Misuse: Like all opioids, fentanyl has a high potential for reliance.
- Cross-Reactivity: It must be utilized with severe care in patients who have 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

- Storage: Must be kept in a double-locked "CD" (Controlled Drug) cabinet.
- Record Keeping: Every milligram must be accounted for in a Controlled Drugs Register.
- Prescribing: Prescriptions must fulfill particular legal requirements regarding the total quantity and formulation.
- Destruction: Any unused portions of an ampoule should be seen and damaged according to hospital procedures.
