Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a potent synthetic opioid analgesic, extensively acknowledged in clinical medicine for its rapid start and short period of action. Within the United Kingdom's healthcare system, fentanyl plays a crucial function in perioperative care, extensive care, and the management of acute, serious pain. Since of its strength-- approximated to be 50 to 100 times that of morphine-- its administration via injection is strictly controlled and generally reserved for healthcare facility settings.
For healthcare experts, trainees, or clients looking for to understand the pharmacological landscape in the UK, identifying the readily available brand names and makers of fentanyl citrate injection is necessary. This article offers an extensive summary of the brand name names, scientific signs, 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 powerful agonist at the μ-opioid (mu-opioid) receptors in the main 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 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 intense pain relief while maintaining hemodynamic stability, making it a favored choice for cardiac surgeries and for clients with vulnerable 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. Nevertheless, several manufacturers provide the NHS and personal hospitals with particular formulas. Historically, the most popular brand related to fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still utilized worldwide and informally in some UK theatres, most of the supply in the UK is now offered by generic manufacturing experts.
Table 1: Common Manufacturers and Product Details in the UK
| Manufacturer | 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) |

While the brand "Sublimaze" might 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 item.
Clinical Indications for Injection
Fentanyl citrate injection is made use of throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its use is usually divided into three classifications:
1. Anaesthesia
Fentanyl is a foundation of modern anaesthesia. It is utilized 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 cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl might be administered in small, titrated boluses to manage instant 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 frequently used as an infusion to offer continuous analgesia for patients who are mechanically aerated. website -life permits more predictable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Function of Fentanyl |
|---|---|
| Pre-medication | To offer sedation and analgesia before moving to theatre. |
| Induction | To work together with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To manage the surgical pain stimulus throughout the treatment. |
| Analgesic Supplement | Utilized 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 paths, changing the understanding of and action to discomfort. It likewise increases the discomfort threshold.
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolic process: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Because fentanyl is highly lipid-soluble, it crosses the blood-brain barrier practically immediately, which explains why the analgesic impact is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Just like all potent opioids, fentanyl citrate carries a danger of substantial negative effects, especially associating with the breathing and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major threat; it decreases the drive to breathe.
- Bradycardia: A slow heart rate.
- Hypotension: Low high blood pressure.
- Muscle Rigidity: Specifically "wooden chest syndrome," where the chest wall ends up being too stiff to aerate easily (typically accompanies high-dose rapid 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.
- Breathing anxiety in the absence 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).
Policy and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly controlled to prevent diversion and misuse.
- Storage: It must be kept in a locked "Controlled Drugs" (CD) cabinet that satisfies the British Standard for security.
- Record Keeping: Every dosage administered need to be recorded in a Controlled Drugs Register, signed by two qualified health care professionals (usually a physician and a nurse, or 2 nurses).
- Disposal: Any lost or unused portion of an ampoule must be experienced and destroyed according to local trust policy (usually utilizing a denaturing package).

Naloxone (brand Prenoxad or generic) is the basic opioid villain used to reverse the results of fentanyl if respiratory anxiety occurs.
Summary
Fentanyl citrate stays one of the most important medications in the UK's surgical and intensive care environments. While it may be referred to by the historical brand name Sublimaze, it is primarily used in its generic form provided by makers such as Hameln, Wockhardt, and Martindale Pharma.
