This post provides a thorough introduction of the brand name names, scientific signs, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that acts as a powerful agonist at the μ-opioid (mu-opioid) receptors in the central nervous system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it offers quick analgesia. In the UK, it is categorized 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 ability to supply extreme discomfort relief while maintaining hemodynamic stability, making it a preferred option for cardiac surgeries and for clients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical products are prescribed by their generic name (Fentanyl) instead of a brand. However, Medic Store GB of makers supply the NHS and private healthcare facilities with specific formulas. Historically, the most famous brand connected with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized internationally and informally in some UK theatres, most of the supply in the UK is now provided by generic production specialists.
Table 1: Common Manufacturers and Product Details in the UK
| Maker | 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) |
| Martindale Pharma | Fentanyl Citrate | 50 micrograms/ml (2ml, 10ml, 20ml ampoules) |

While the brand "Sublimaze" may still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic versions, which are bioequivalent to the initial branded item.
Scientific Indications for Injection
Fentanyl citrate injection is used throughout numerous departments, from the Emergency Department (ED) to the Operating Theatre. Its use is typically divided into 3 classifications:
1. Anaesthesia
Fentanyl is a cornerstone of modern anaesthesia. It is utilized as an analgesic supplement during the induction and maintenance of general anaesthesia. It helps blunt the body's physiological "tension action" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to manage immediate post-surgical discomfort before transitions are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is regularly utilized as an infusion to provide continuous analgesia for patients who are mechanically aerated. Its short half-life allows for 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 transferring to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus during the treatment. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to enhance pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending discomfort pathways, changing the understanding of and reaction to discomfort. It likewise increases the pain threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly by means of the kidneys.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier practically immediately, which explains why the analgesic result is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate brings a risk of substantial adverse effects, especially associating with the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most major danger; it reduces 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 easily (generally occurs with high-dose rapid IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or upper body.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the lack of resuscitative devices.
- Concurrent usage of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to avoid diversion and misuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cabinet that satisfies the British Standard for security.
- Record Keeping: Every dose administered should be taped in a Controlled Drugs Register, signed by two competent health care professionals (usually a physician and a nurse, or two nurses).
- Disposal: Any wasted or unused part of an ampoule should be witnessed and damaged according to regional trust policy (normally using a denaturing set).
