Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, extensively recognized in medical medication for its fast onset and brief duration of action. Within the United Kingdom's healthcare system, fentanyl plays a vital role in perioperative care, extensive care, and the management of acute, extreme discomfort. Since of its effectiveness-- approximated to be 50 to 100 times that of morphine-- its administration via injection is strictly managed and typically scheduled for hospital settings.
For health care professionals, students, or patients looking for to understand the pharmacological landscape in the UK, identifying the available brand and manufacturers of fentanyl citrate injection is vital. This blog post offers a thorough introduction of the brand names, scientific indicators, 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 worried system. When administered through 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 main appeal in surgical settings is its capability to supply extreme pain relief while preserving hemodynamic stability, making it a preferred choice for heart surgical treatments and for clients with delicate cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, lots of pharmaceutical items are prescribed by their generic name (Fentanyl) rather than a brand. Nevertheless, a number of producers provide the NHS and personal hospitals with specific solutions. Historically, the most popular brand name connected with fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still utilized globally and informally in some UK theatres, most of the supply in the UK is now offered by generic production experts.
Table 1: Common Manufacturers and Product Details in the UK
| Producer | Item Description | Common 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 dominated by Hameln and Martindale generic variations, which are bioequivalent to the initial top quality product.
Medical Indications for Injection
Fentanyl citrate injection is made use of across various departments, from the Emergency Department (ED) to the Operating Theatre. Its use is generally divided into three classifications:
1. Anaesthesia
Fentanyl is a cornerstone of modern-day anaesthesia. It is used as an analgesic supplement during the induction and maintenance of basic anaesthesia. It assists blunt the body's physiological "stress action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to manage immediate 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 regularly utilized as an infusion to supply constant analgesia for clients who are mechanically ventilated. Its brief half-life permits for more predictable "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 transition to unconsciousness. |
| Upkeep | To manage the surgical pain stimulus during the procedure. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to boost pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders rising discomfort pathways, changing the perception of and action to discomfort. It likewise increases the discomfort limit.
- Onset 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.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly immediately, which explains why the analgesic effect is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Just like all powerful opioids, fentanyl citrate carries a danger of substantial side results, particularly associating with the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious danger; it lowers the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wood chest syndrome," where the chest wall becomes too stiff to ventilate easily (usually takes place with high-dose fast IV administration).
- Queasiness and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the absence of resuscitative devices.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (risk of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to avoid diversion and abuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered must be recorded in a Controlled Drugs Register, signed by 2 competent health care experts (typically a doctor and a nurse, or more nurses).
- Disposal: Any squandered or unused part of an ampoule must be experienced and damaged according to regional trust policy (typically utilizing a denaturing set).
