Pregabalin is recommended by the National Institute for Health and Care Excellence (NICE) as one of the first-line options for neuropathic pain (except for trigeminal neuralgia) in adults, along with gabapentin, amitriptyline price of pregabalin 75mg and duloxetine​5​. Amira Guirguis, MPharm programme director at Swansea University and an expert in novel psychoactive substances, adds that the potency of pregabalin might explain prescribers’ preference for it over gabapentin. “Across various studies, pregabalin consistently demonstrates a greater potency than gabapentin​3​. This discrepancy in potency is likely attributed to differences in their respective pharmacokinetic profiles,” she says, with pregabalin being absorbed more rapidly and achieving a higher bioavailability. But a marked increase in the number of deaths linked to the drugs triggered their reclassification as a Class C controlled drug in April 2019, which introduced greater restrictions on prescribing. This observational drug utilisation study (DUS) analysed pregabalin prescription data from the UK Health Improvement Network primary care database between September 2004 and July 2009.

• When sample extracts were injected into the LC column and eluted into the mass spectrometer, the transitions of PGL and monitored adulterants were automatically detected and peaks were produced in the chromatograms.
• Various capsule samples contained mixtures of PGL and codeine, a derivative of morphine that can cause serious respiratory failure.
• “Now that we have more pharmacists working within general practices, should they be reviewing patients taking pregabalin and gabapentin to ensure it is being prescribed appropriately?
• In Scotland, gabapentin and/or pregabalin was implicated in 367 drug misuse deaths in 2022, down from a peak of 502 deaths in 2020 (see Figure 6).
• It is well-known that pharmaceutical analysis relies heavily on liquid chromatography (LC).
• Furthermore, five samples (1C, 3C, 5C, 10C, and 13C) exceeded the upper BP limit (105%).

UPLC-PDA analysis of three independent preparations of each seized pregabalin powder sample. Pregabalin (PGL) is a medication that is prescribed for controlling specific neurological-related symptoms. Due to its abuse in multiple countries, PGL has been classified as a controlled substance by authorities, including the Saudi Food and Drug Authority (SFDA).
