5 Fentanyl Citrate Injection Brands UK Lessons From Professionals
Fentanyl Citrate Injection: A Comprehensive Guide to Brands and Clinical Use in the UK
Fentanyl citrate is a powerful synthetic opioid analgesic that has actually remained a cornerstone of anesthesia and extensive care medicine because its development in the 1960s. In the United Kingdom, it is categorized as a Class A drug under the Misuse of Drugs Act 1971 and is strictly controlled as a Schedule 2 Controlled Drug (CD). Mostly utilized for its quick start and brief period of action, fentanyl citrate injection is a necessary tool for clinicians managing sharp pain, surgical analgesia, and sedation.
This short article supplies a thorough exploration of the fentanyl citrate injection brands available in the UK, their clinical indicators, regulatory framework, and security profiles.
Comprehending Fentanyl Citrate
Fentanyl citrate is approximately 50 to 100 times more powerful than morphine. Its high lipid solubility permits it to cross the blood-brain barrier rapidly, offering nearly instant analgesic effects when administered intravenously. In the UK health care system, it is mostly made use of in hospital settings-- particularly in operating theatres, emergency situation departments, and Intensive Care Units (ICUs).
Scientific Indications
The scientific applications of fentanyl citrate injection in the UK are broad but particular to regulated environments:
- Analgesic Supplement: Used throughout personnel treatments to offer profound analgesia.
- Induction of Anesthesia: Often utilized along with induction representatives to blunt the cardiovascular response to intubation.
- Post-operative Pain Management: Administered in healing spaces for instant relief of severe discomfort.
- Sedation: Used in ICUs for patients requiring mechanical ventilation.
Fentanyl Citrate Injection Brands in the UK
In the United Kingdom, while the initial brand established by Janssen-Cilag was Sublimaze, the marketplace is now controlled by top quality generic versions produced by different pharmaceutical companies. These products must be authorized by the Medicines and Healthcare items Regulatory Agency (MHRA) to ensure they fulfill strict safety and effectiveness standards.
Leading Manufacturers and Suppliers
The UK supply chain for fentanyl citrate injection depends on a number of crucial players:
- Hameln Pharma: One of the most typical suppliers in NHS health centers. They offer fentanyl in numerous sizes of ampoules.
- Martindale Pharma (Ethypharm): A major UK-based manufacturer focusing on critical care and sterile injectables.
- Mawdsleys Specialty Services: Often involved in the distribution and supply of specialized formulations.
- Wockhardt UK: Provides generic alternatives for healthcare facility use.
Summary of Available Presentations
The following table lays out the typical brands and discussions of fentanyl citrate injection currently used within the UK healthcare facilities.
| Brand/Manufacturer | Typical Concentration | Offered Volume (Fill Size) | Total Content |
|---|---|---|---|
| Sublimaze (Janssen) | 50 micrograms/ml | 2ml, 10ml | 100mcg, 500mcg |
| Hameln Pharma | 50 micrograms/ml | 2ml, 10ml, 20ml | 100mcg, 500mcg, 1mg |

| Wockhardt UK | 50 micrograms/ml | 2ml, 10ml | 100mcg, 500mcg |
Pharmacology and Mechanism of Action
Fentanyl acts primarily as an agonist at the mu-opioid receptors in the main nervous system (CNS). By binding to these receptors, it prevents rising discomfort pathways, modifies the understanding of and response to pain, and produces generalized CNS anxiety.
Key Pharmacokinetic Properties:
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Duration: 30-- 60 minutes (much shorter than morphine due to redistribution into fat and muscle).
- Metabolism: Hepatic via the CYP3A4 enzyme system.
- Excretion: Primarily renal.
Regulatory and Safety Requirements in the UK
Because fentanyl citrate is a Schedule 2 Controlled Drug, its handling in the UK undergoes the Misuse of Drugs Regulations 2001. These regulations mandate rigorous procedures to avoid diversion and ensure client security.
Legal Requirements for Healthcare Facilities:
- Storage: Must be stored in a locked, double-bolted cupboard (CD cabinet) that fulfills British Standards.
- Record Keeping: Every dosage administered, gotten, or discarded should be tape-recorded in a Controlled Drugs Register (CDR).
- Recommending: All prescriptions should fulfill specific legal requirements, including the total quantity composed in both words and figures.
- Destruction: Expired or polluted vials should be "rendered irretrievable" in the presence of an authorized witness.
Common Side Effects and Adverse Reactions
While extremely efficient, fentanyl citrate brings a risk of significant side effects, especially if not titrated thoroughly.
Breathing System:The most critical negative effects is respiratory depression. This is dose-dependent and can lead to apnea if the patient is not kept an eye on or aerated.
Cardiovascular System:Fentanyl can cause bradycardia (slow heart rate) and hypotension, though it is usually thought about more cardiovascularly stable than morphine.
Musculoskeletal System:An unique adverse effects of fast, high-dose fentanyl administration is "wooden chest syndrome" (skeletal muscle rigidity), which can make mechanical ventilation hard.
Other Common Side Effects:
- Nausea and vomiting.
- Lightheadedness or bliss.
- Pruritus (itching).
- Biliary system spasm.
Administration Guidelines
In the UK, fentanyl citrate injections are typically administered by anesthesiologists, specifically trained nurses, or emergency situation medicine clinicians.
- Intravenous (IV) Bolus: Used for fast pain relief or induction of anesthesia.
- Constant Infusion: Common in the ICU for long-lasting sedation. Concentrations are often standardized by regional hospital trusts (e.g., 1mg in 50ml or 2.5 mg in 50ml).
- Patient-Controlled Analgesia (PCA): Less typical than morphine PCAs, however used for clients with morphine allergic reactions or renal disability.
Comparison of Fentanyl vs. Other Injectable Opioids
| Function | Fentanyl | Morphine | Remifentanil |
|---|---|---|---|
| Potency (Approx) | 100x Morphine | 1x (Baseline) | 100x Morphine |
| Beginning | Really Rapid (1-2 minutes) | Moderate (15-30 minutes) | Immediate (30-60 sec) |
| Duration | Brief (30-60 minutes) | Long (4 hours) | Ultra-short (3-10 minutes) |
| Histamine Release | Very Low | High | Low |
| UK Legal Status | Schedule 2 CD | Arrange 2 CD | Set up 2 CD |
Fentanyl citrate injection stays an indispensable part of the UK's pharmacological arsenal for discomfort management and anesthesia. While trademark name like Sublimaze are well-known, generic variations from Hameln and Martindale supply the backbone of hospital supplies, ensuring economical and reliable access to this life-saving medication. read more to its extreme potency and potential for breathing depression, its use is strictly confined to medical environments where resuscitation equipment and trained personnel are right away available.
