Fentanyl citrate is a potent artificial opioid analgesic, extensively recognized in medical medication for its fast beginning and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays a critical function in perioperative care, extensive care, and the management of severe, severe pain. Because of its effectiveness-- approximated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and usually reserved for hospital settings.
For health care specialists, trainees, or clients seeking to understand the pharmacological landscape in the UK, identifying the offered brand name names and producers of fentanyl citrate injection is vital. This blog post offers an extensive summary of the brand, medical indications, and regulative status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that functions as a potent agonist at the μ-opioid (mu-opioid) receptors in the central nerve system. When administered via intravenous (IV) or intramuscular (IM) injection, it supplies fast analgesia. In Fentanyl Citrate UK , it is classified as a Class A controlled drug under the Misuse of Drugs Act 1971 and falls under Schedule 2 of the Misuse of Drugs Regulations 2001.
Its main appeal in surgical settings is its capability to supply extreme pain relief while maintaining hemodynamic stability, making it a favored option for cardiac surgeries and for patients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are recommended by their generic name (Fentanyl) instead of a brand. However, numerous manufacturers supply the NHS and private hospitals with particular formulas. Historically, the most famous brand associated with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still utilized globally and colloquially in some UK theatres, most of the supply in the UK is now supplied by generic manufacturing specialists.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Item Description | Typical Strengths |
|---|---|---|
| Hameln Pharma | Fentanyl Citrate Injection BP | 50 micrograms/ml (2ml, 10ml ampoules) |
| Wockhardt UK | Fentanyl Citrate Injection | 50 micrograms/ml (2ml, 10ml ampoules) |

Clinical Indications for Injection
Fentanyl citrate injection is made use of across various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is normally divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is used as an analgesic supplement during the induction and upkeep of general anaesthesia. It assists blunt the body's physiological "tension action" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may be administered in small, titrated boluses to manage instant post-surgical pain before transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently used as an infusion to provide constant analgesia for clients who are mechanically ventilated. Its brief half-life permits more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before moving to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth shift to unconsciousness. |
| Maintenance | To handle the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to improve discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. Fentanyl Liquid UK ascending pain pathways, altering the perception of and action to pain. It also increases the pain limit.
- Beginning of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which discusses why the analgesic impact is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate brings a danger of significant side impacts, particularly connecting to the respiratory and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall ends up being too stiff to ventilate quickly (typically occurs with high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, frequently around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the absence of resuscitative equipment.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (threat of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Policy and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to avoid diversion and abuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that satisfies the British Standard for security.
- Record Keeping: Every dosage administered need to be taped in a Controlled Drugs Register, signed by two certified healthcare experts (normally a medical professional and a nurse, or 2 nurses).
- Disposal: Any wasted or unused part of an ampoule should be seen and destroyed according to local trust policy (normally utilizing a denaturing set).
