Top purity Pregabalin148553-50-8 Usage

Pregabalin (Lyrica) was the first drug approved by the Food and Drug Administration for the treatment of postherpetic neuralgia and diabetic neuropathy. Pregabalin has been used in the management of other anxiety disorders and acute anxiety states such as preoperative anxiety. It is widely used as a treatment for multiple neurological disorders. As a capping and reducing agent, the dose of pregabalin (PREG)  must be customised according to patients’ characteristics  and main symptoms.


Side Effects

Weight gain is one of the most common side effects with Lyrica (generic name: pregabalin) in both adults and children. Pregabalin treatment is associated with a high risk for bodyweight gain which in part depends on total anticonvulsant drug load.

Efficacy and safety of pregabalin in eye pain: A systematic review

X Shen, X Chen, Y He, H Xu, J Zhu

Medicine, Volume 102, Number 6, 10 February 2023, pp. e32875-e32875(1)

The pregabalin is approved for the management of persistent pain. Pregabalin reduced acute eye pain but had no significant effect on long-term analgesia after ophthalmological surgery in adults. It had no effect on dry-eye symptoms after ocular surgery. Further studies on the safety of pregabalin in eye pain management 

A meta-epidemiological study on the reported treatment effect of pregabalin in neuropathic pain trials over time

PloS one, January 20, 2023

We included randomized, placebo-controlled trials of pregabalin for treatment of neuropathic pain in adults. The reported treatment effect or analgesic efficacy of pregabalin from clinical trials has diminished over time. Clinical recommendations may need to be re-evaluated to account for recent evidence and to consider whether pregabalin therapy is indicated.
