Fentanyl Citrate Injection: A Comprehensive Guide to Brands and Clinical Use in the UK
Fentanyl citrate is a powerful artificial opioid analgesic that has actually remained a foundation of anesthesia and extensive care medication 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 managed as a Schedule 2 Controlled Drug (CD). Primarily utilized for its quick start and short duration of action, fentanyl citrate injection is an important tool for clinicians handling severe discomfort, surgical analgesia, and sedation.
This post provides a thorough expedition of the fentanyl citrate injection brands readily available in the UK, their clinical signs, regulatory structure, and security profiles.
Understanding Fentanyl Citrate
Fentanyl citrate is approximately 50 to 100 times more potent than morphine. Fentanyl Transdermal System UK enables it to cross the blood-brain barrier quickly, providing practically instant analgesic impacts when administered intravenously. In the UK healthcare system, it is mainly used in medical facility settings-- specifically in operating theatres, emergency departments, and Intensive Care Units (ICUs).
Medical Indications
The scientific applications of fentanyl citrate injection in the UK are broad however particular to controlled environments:
- Analgesic Supplement: Used during operative procedures to supply profound analgesia.
- Induction of Anesthesia: Often utilized alongside induction agents to blunt the cardiovascular reaction to intubation.
- Post-operative Pain Management: Administered in recovery spaces for instant relief of serious discomfort.
- Sedation: Used in ICUs for patients needing mechanical ventilation.
Fentanyl Citrate Injection Brands in the UK
In the United Kingdom, while the initial brand name established by Janssen-Cilag was Sublimaze, the market is now controlled by top quality generic versions made by various pharmaceutical companies. These products should be licensed by the Medicines and Healthcare items Regulatory Agency (MHRA) to ensure they fulfill rigid safety and efficacy standards.

- Martindale Pharma (Ethypharm): A significant UK-based maker focusing on important care and sterilized injectables.
- Mawdsleys Specialty Services: Often associated with the distribution and supply of specialized formulations.
- Wockhardt UK: Provides generic options for medical facility use.
Summary of Available Presentations
The following table details the typical brand names and discussions of fentanyl citrate injection presently used within the UK healthcare facilities.
| Brand/Manufacturer | Common Concentration | Readily Available Volume (Fill Size) | Total Content |
|---|---|---|---|
| Sublimaze (Janssen) | 50 micrograms/ml | 2ml, 10ml | 100mcg, 500mcg |

Pharmacology and Mechanism of Action
Fentanyl acts mostly as an agonist at the mu-opioid receptors in the main nerve system (CNS). By binding to these receptors, it hinders ascending discomfort paths, alters the understanding of and action to discomfort, and produces generalized CNS depression.
Key Pharmacokinetic Properties:
- Onset of Action: 1-- 2 minutes (Intravenous).
- Peak Effect: 3-- 5 minutes.
- Period: 30-- 60 minutes (shorter than morphine due to redistribution into fat and muscle).
- Metabolism: Hepatic by means of the CYP3A4 enzyme system.
- Excretion: Primarily renal.
Regulatory and Safety Requirements in the UK
Due to the fact that fentanyl citrate is a Schedule 2 Controlled Drug, its handling in the UK undergoes the Misuse of Drugs Regulations 2001. These guidelines mandate rigorous protocols to avoid diversion and guarantee patient safety.
Legal Requirements for Healthcare Facilities:
- Storage: Must be saved in a locked, double-bolted cabinet (CD cabinet) that fulfills British Standards.
- Record Keeping: Every dose administered, received, or discarded should be tape-recorded in a Controlled Drugs Register (CDR).
- Prescribing: All prescriptions must satisfy specific legal requirements, consisting of the overall quantity written 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 carries a risk of substantial negative effects, especially if not titrated carefully.
Breathing System:The most vital adverse effects is respiratory anxiety. click here is dose-dependent and can result in apnea if the client is not kept an eye on or ventilated.
Cardiovascular System:Fentanyl can cause bradycardia (sluggish heart rate) and hypotension, though it is usually thought about more cardiovascularly stable than morphine.
Musculoskeletal System:A special side effect of fast, high-dose fentanyl administration is "wood chest syndrome" (skeletal muscle rigidness), which can make mechanical ventilation hard.
Other Common Side Effects:
- Nausea and throwing up.
- Dizziness or bliss.
- Pruritus (itching).
- Biliary system convulsion.
Administration Guidelines
In the UK, fentanyl citrate injections are generally administered by anesthesiologists, specially trained nurses, or emergency medication clinicians.
- Intravenous (IV) Bolus: Used for rapid pain relief or induction of anesthesia.
- Continuous Infusion: Common in the ICU for long-term sedation. Fentanyl Lollipop UK are frequently 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 made use of for clients with morphine allergic reactions or renal impairment.
Contrast of Fentanyl vs. Other Injectable Opioids
| Feature | Fentanyl | Morphine | Remifentanil |
|---|---|---|---|
| Effectiveness (Approx) | 100x Morphine | 1x (Baseline) | 100x Morphine |
| Beginning | Extremely Rapid (1-2 minutes) | Moderate (15-30 minutes) | Immediate (30-60 sec) |
| Duration | Short (30-60 min) | Long (4 hours) | Ultra-short (3-10 min) |
| Histamine Release | Very Low | High | Low |
| UK Legal Status | Arrange 2 CD | Schedule 2 CD | Set up 2 CD |
