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 clinical medicine for its quick beginning and short period of action. Within the United Kingdom's health care system, fentanyl plays a crucial function in perioperative care, extensive care, and the management of severe, severe discomfort. Since of its potency-- estimated to be 50 to 100 times that of morphine-- its administration via injection is strictly managed and generally reserved for healthcare facility settings.
For health care professionals, students, or clients looking for to understand the pharmacological landscape in the UK, determining the available brand and producers of fentanyl citrate injection is vital. This blog site post provides an extensive overview of the trademark name, clinical indicators, and regulative 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 central nerve system. When administered via intravenous (IV) or intramuscular (IM) injection, it offers fast analgesia. In the UK, it is categorized 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 offer extreme pain relief while preserving hemodynamic stability, making it a favored option for cardiac surgical treatments and for patients with vulnerable 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) rather than a trademark name. However, a number of manufacturers supply the NHS and private healthcare facilities with specific solutions. Historically, the most popular brand connected with fentanyl citrate was Sublimaze, initially developed by Janssen Pharmaceutica. While the name Sublimaze is still utilized globally and informally in some UK theatres, the bulk of the supply in the UK is now offered by generic production professionals.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | Product 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 |
| Pirimal Critical Care | Fentanyl Citrate Injection | 50 micrograms/ml |
While the brand name "Sublimaze" might still appear on some procurement lists, the UK medical landscape is dominated by Hameln and Martindale generic variations, which are bioequivalent to the original branded item.
Clinical Indications for Injection
Fentanyl citrate injection is utilized across various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is generally divided into three categories:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is used as an analgesic supplement throughout the induction and upkeep of basic anaesthesia. It helps blunt the body's physiological "stress response" to intubation and surgical incision.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to handle immediate 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 often utilized as an infusion to provide constant analgesia for clients who are mechanically ventilated. Its brief half-life permits more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To supply 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 discomfort stimulus throughout the procedure. |
| Analgesic Supplement | Utilized in local anaesthesia (like epidurals) to boost discomfort relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain pathways, modifying the perception of and response to pain. It likewise increases the discomfort limit.
- 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 by means of the CYP3A4 enzyme.
- Excretion: Mostly through the kidneys.
Because fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier almost instantly, which discusses why the analgesic impact is felt so much faster than with morphine or oxycodone.
Security and Side Effects
Similar to all potent opioids, fentanyl citrate carries a danger of substantial side impacts, particularly connecting to the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious threat; it reduces the drive to breathe.
- Bradycardia: A sluggish heart rate.
- Hypotension: Low blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to aerate quickly (typically accompanies high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, typically around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Respiratory anxiety in the lack of resuscitative equipment.
- Concurrent use of Monoamine Oxidase Inhibitors (MAOIs) within the last 14 days (danger of serotonin syndrome).
- Myasthenia gravis (due to muscle-relaxing interactions).
Regulation and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly managed to prevent diversion and abuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that meets the British Standard for security.
- Record Keeping: Every dosage administered should be tape-recorded in a Controlled Drugs Register, signed by two certified healthcare professionals (typically a medical professional and a nurse, or more nurses).
- Disposal: Any lost or unused part of an ampoule need to be witnessed and ruined according to regional trust policy (generally using a denaturing kit).
