Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful synthetic opioid analgesic, widely recognized in medical medication for its fast onset and brief duration of action. Within the United Kingdom's health care system, fentanyl plays a crucial role in perioperative care, intensive care, and the management of severe, serious pain. Because of its potency-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly controlled and generally scheduled for hospital settings.
For healthcare experts, students, or patients looking for to comprehend the medicinal landscape in the UK, identifying the available brand names and makers of fentanyl citrate injection is important. This article offers a detailed introduction of the brand, scientific indicators, 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 nerve system. When administered by means of intravenous (IV) or intramuscular (IM) injection, it supplies rapid analgesia. In Fentanyl Test Strips 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 primary appeal in surgical settings is its ability to offer intense discomfort relief while preserving hemodynamic stability, making it a preferred option for cardiac surgical treatments and for clients with fragile cardiovascular systems.
Fentanyl Citrate Injection Brand Names and Manufacturers in the UK
In the UK market, numerous pharmaceutical items are prescribed by their generic name (Fentanyl) instead of a brand. Nevertheless, a number of makers supply the NHS and personal medical facilities with specific solutions. Historically, the most well-known brand connected with fentanyl citrate was Sublimaze, originally established by Janssen Pharmaceutica. While the name Sublimaze is still utilized globally and colloquially in some UK theatres, the majority of the supply in the UK is now offered by generic production specialists.

Scientific Indications for Injection
Fentanyl citrate injection is used across various departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is typically divided into 3 categories:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is utilized as an analgesic supplement during the induction and maintenance of basic anaesthesia. Fentanyl Addiction Treatment UK assists blunt the body's physiological "tension action" to intubation and surgical cut.
2. Post-operative Recovery
In the Recovery Room (PACU), fentanyl may 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 offer constant analgesia for clients who are mechanically aerated. Fentanyl Citrate Sublingual UK -life enables more foreseeable "wake-up" tests compared to drugs like morphine.
Table 2: Clinical Application Summary
| Application | Role of Fentanyl |
|---|---|
| Pre-medication | To supply sedation and analgesia before transferring to theatre. |
| Induction | To cooperate with induction representatives (like Propofol) for a smooth transition to unconsciousness. |
| Upkeep | To manage the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Used in local anaesthesia (like epidurals) to enhance pain relief. |
Mechanism of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding hinders ascending pain paths, modifying the perception of and reaction to pain. It also increases the pain threshold.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it extremely titratable).
- Metabolism: Primarily in the liver via 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 effect is felt a lot faster than with morphine or oxycodone.
Safety and Side Effects
Just like all powerful opioids, fentanyl citrate brings a risk of considerable side results, especially associating with the breathing and cardiovascular systems.
Common Side Effects:
- Respiratory Depression: The most serious threat; it minimizes 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 ventilate quickly (normally accompanies high-dose quick IV administration).
- Queasiness and Vomiting: Common in the post-operative stage.
- Pruritus: Itching, frequently around the nose or upper body.
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).
Guideline and Storage in the UK
In the United Kingdom, fentanyl citrate is strictly regulated to avoid diversion and abuse.
- Storage: It should be kept in a locked "Controlled Drugs" (CD) cupboard that satisfies the British Standard for security.
- Record Keeping: Every dose administered should be recorded in a Controlled Drugs Register, signed by two competent healthcare professionals (generally a medical professional and a nurse, or 2 nurses).
- Disposal: Any squandered or unused portion of an ampoule should be witnessed and damaged according to regional trust policy (usually using a denaturing set).
