What is Fentanyl Citrate?

Fentanyl citrate is the salt type of fentanyl, created by the response of fentanyl base with citric acid. This conversion is essential for medical usage because fentanyl base itself has bad water solubility, making it hard to create into the aqueous services required for intravenous (IV) or intramuscular (IM) injections.

In the UK, fentanyl citrate is managed under the Misuse of Drugs Act 1971 as a Class A regulated substance and is handled under Schedule 2 of the Misuse of Drugs Regulations 2001. Its primary clinical applications include:

• Management of extreme persistent pain (typically through transdermal spots).
• Analgesia during anaesthesia.

• Advancement cancer pain (through buccal or sublingual paths).

The Chemical Profile of Solubility

Solubility refers to the optimum amount of a compound (the solute) that can dissolve in a particular volume of solvent at an offered temperature and pressure. For fentanyl citrate, solubility is influenced heavily by its salt kind and the pH of the environment.

1. Solubility in Water

Fentanyl citrate is categorized by the British Pharmacopoeia (BP) as being “soluble in water.” Unlike Black Market Fentanyl UK , the citrate salt enables for stable aqueous preparations. At room temperature level (around 20 ° C to 25 ° C), the solubility of fentanyl citrate in water is roughly 25 mg/mL to 33 mg/mL. This high level of solubility is what permits the development of extremely concentrated “sublimaze” solutions used in operating theatres across the UK.

2. Solubility in Organic Solvents

While it performs well in water, fentanyl citrate shows differing degrees of solubility in organic solvents. It is moderately soluble in alcohol (ethanol) and chloroform, and virtually insoluble in ether.
