Pregabalin UKCPA Handbook of Perioperative Medicines

Pregabalin misusers achieve euphoric effects by taking large quantities, ranging from 200mg lyrica online to 5g as a single dose (maximum licensed dose is 600mg daily in two or three divided doses); its pharmacokinetics make it relatively more dangerous than gabapentin in high doses​12​.

• In England and Wales, the latest data for drug-related poisonings where pregabalin was mentioned on the death certificate show an increase from 187 deaths in 2018 to 441 deaths in 2022.
• Irregular crystal structures were noticed compared to the well-defined structures typically expected for pure PGL.
• Despite these risks, co-prescribing of gabapentinoids with opioids and other dependency-forming drugs appears to be increasing.
• In this context, a limited number of analytical methods were developed for PGL quantification in various sample matrices for clinical and forensic applications.

3 Analysis of capsule samples

However, a recent study suggested there was widespread off-label prescribing of pregabalin for non-neuropathic pain — most commonly musculoskeletal conditions, such as low back pain — between 1997 and 2019 (see Figure 3)​2​. Thus, through utilizing MRM-LC-MS/MS and targeted analyte transitions, seized drug samples were successfully profiled, impurities were detected, and adulteration trends were uncovered – providing valuable data on the illegal market and risks to public health. The LOD and LOQ values based on residual SD of the regression line were 0.23 and 0.69 mg/mL, respectively.
