Fentanyl Citrate Injection in the UK: A Guide to Brand Names, Uses, and Clinical Overview
Fentanyl citrate is a powerful artificial opioid analgesic, commonly acknowledged in medical medication for its fast onset and short period of action. Within the United Kingdom's healthcare system, fentanyl plays a critical function in perioperative care, extensive care, and the management of intense, serious discomfort. Due to the fact that of its potency-- estimated to be 50 to 100 times that of morphine-- its administration by means of injection is strictly managed and generally reserved for healthcare facility settings.
For healthcare specialists, trainees, or clients looking for to understand the pharmacological landscape in the UK, determining the offered trademark name and producers of fentanyl citrate injection is vital. This post offers an extensive introduction of the trademark name, clinical 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 potent 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 supplies rapid analgesia. In the UK, it is classified as a Class A controlled 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 supply intense pain relief while preserving hemodynamic stability, making it a favored option for cardiac surgical treatments and for clients with vulnerable 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) rather than a brand. However, several makers provide the NHS and personal healthcare facilities with particular formulas. Historically, the most popular brand name connected with fentanyl citrate was Sublimaze, initially established by Janssen Pharmaceutica. While the name Sublimaze is still used internationally and colloquially in some UK theatres, the majority of the supply in the UK is now offered by generic production specialists.
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 trademark name "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 initial top quality product.
Medical Indications for Injection
Fentanyl citrate injection is made use of throughout different departments, from the Emergency Department (ED) to the Operating Theatre. Its usage is usually divided into 3 classifications:
1. Anaesthesia
Fentanyl is a foundation of contemporary anaesthesia. It is utilized as an analgesic supplement throughout the induction and upkeep of general anaesthesia. It helps 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 little, titrated boluses to handle 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 ventilated. Fentanyl Citrate Injection Formulations UK -life enables more foreseeable "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 transferring to theatre. |
| Induction | To work together with induction agents (like Propofol) for a smooth transition to unconsciousness. |
| Maintenance | To handle the surgical discomfort stimulus during the treatment. |
| Analgesic Supplement | Utilized in regional anaesthesia (like epidurals) to enhance pain relief. |
System of Action and Pharmacokinetics
Fentanyl works by binding to mu-opioid receptors. This binding prevents ascending pain paths, altering the understanding of and response to pain. It likewise increases the discomfort threshold.
- Start of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (making it highly titratable).
- Metabolism: Primarily in the liver through the CYP3A4 enzyme.
- Excretion: Mostly via the kidneys.
Due to the fact that fentanyl is extremely lipid-soluble, it crosses the blood-brain barrier nearly instantly, which describes why the analgesic effect is felt a lot faster than with morphine or oxycodone.
Security and Side Effects
Similar to all powerful opioids, fentanyl citrate carries a threat of substantial side impacts, especially connecting to the breathing and cardiovascular systems.
Typical Side Effects:
- Respiratory Depression: The most major risk; it minimizes 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 aerate easily (typically accompanies high-dose rapid IV administration).
- Nausea and Vomiting: Common in the post-operative phase.
- Pruritus: Itching, often around the nose or torso.
Contraindications and Cautions:
- Known hypersensitivity to fentanyl or other opioid agonists.
- Breathing depression 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 regulated to avoid diversion and misuse.
- Storage: It needs to be kept in a locked "Controlled Drugs" (CD) cupboard that fulfills the British Standard for security.
- Record Keeping: Every dosage administered need to be taped in a Controlled Drugs Register, signed by two qualified healthcare experts (generally a medical professional and a nurse, or 2 nurses).
- Disposal: Any wasted or unused portion of an ampoule need to be witnessed and ruined according to regional trust policy (normally using a denaturing package).

3. Can Fentanyl injection be offered in the house?
No. Fentanyl citrate injection is nearly specifically used in health center settings (theatre, ICU, A&E) since of the danger of fast breathing anxiety, which requires instant access to oxygen and resuscitation devices.

Fentanyl is roughly 50 to 100 times more potent than morphine. This indicates 100 micrograms of fentanyl is approximately comparable to 10 milligrams of morphine.
5. What is the antidote for a Fentanyl overdose?
Naloxone (trademark name Prenoxad or generic) is the basic opioid antagonist utilized to reverse the results of fentanyl if breathing depression takes place.
Summary
