Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, commonly recognized in scientific medication for its quick beginning and brief period of action. Within the United Kingdom's healthcare system, fentanyl plays an important function in perioperative care, intensive care, and the management of intense, extreme pain. Because of its strength-- approximated to be 50 to 100 times that of morphine-- its administration through injection is strictly managed and generally scheduled for health center settings.
For health care experts, trainees, or clients seeking to comprehend the medicinal landscape in the UK, determining the available brand and manufacturers of fentanyl citrate injection is important. This blog post offers a detailed introduction of the brand name names, clinical indicators, and regulatory status of fentanyl citrate injections in the United Kingdom.
What is Fentanyl Citrate?
Fentanyl citrate is a phenylpiperidine derivative that serves as a potent agonist at the μ-opioid (mu-opioid) receptors in the main anxious system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it supplies rapid analgesia. In the UK, it is classified as a Class A managed drug under the Misuse of Drugs Act 1971 and falls under Schedule 2 of the Misuse of Drugs Regulations 2001.
Its primary appeal in surgical settings is its capability to provide intense discomfort relief while maintaining hemodynamic stability, making it a favored choice for cardiac surgical treatments and for patients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, many pharmaceutical items are recommended by their generic name (Fentanyl) instead of a trademark name. Nevertheless, a number of manufacturers supply the NHS and personal hospitals with particular formulas. Historically, the most popular brand name associated with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still used internationally and informally in some UK theatres, the bulk of the supply in the UK is now supplied by generic production experts.
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) |
| Martindale Pharma | Fentanyl Citrate | 50 micrograms/ml (2ml, 10ml, 20ml ampoules) |
| Janssen-Cilag | Sublimaze (Historical Brand) | 50 micrograms/ml |

While the brand name "Sublimaze" may still appear on some procurement lists, the UK medical landscape is controlled by Hameln and Martindale generic variations, which are bioequivalent to the original branded product.
Medical Indications for Injection
Fentanyl citrate injection is utilized across different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into 3 categories:
1. Anaesthesia
Fentanyl is a cornerstone of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and maintenance of general anaesthesia. It assists blunt the body's physiological "stress reaction" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle instant post-surgical discomfort before shifts are made to longer-acting opioids or oral medications.
3. Intensive Care (ICU)
In the Intensive Care Unit, fentanyl is frequently utilized as an infusion to offer constant analgesia for patients who are mechanically aerated. Its short half-life enables more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To provide sedation and analgesia before moving to theatre. |
| Induction | To cooperate with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To handle the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding inhibits ascending discomfort pathways, changing the understanding of and response to pain. It likewise increases the pain threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier nearly quickly, which explains why the analgesic result is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Just like all potent opioids, fentanyl citrate carries a threat of considerable adverse effects, especially relating to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most major risk; it minimizes the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to aerate quickly (normally accompanies high-dose rapid IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing anxiety in the lack 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).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to avoid diversion and misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that meets the British Standard for security.
- Record Keeping: Every dose administered need to be tape-recorded in a Controlled Drugs Register, signed by 2 qualified health care experts (normally a doctor and a nurse, or 2 nurses).
- Disposal: Any squandered or unused part of an ampoule need to be witnessed and damaged according to local trust policy (generally using a denaturing kit).
