Gabapentin, an AED approved for the adjunctive treatment of partial seizures with/without secondary generalization and for the treatment of postherpetic neuralgia, is frequently used off-label for the treatment of both psychiatric and pain disorders. Since gabapentin is cleared solely by renal excretion, dosing requires consideration of the patient's renal function. Myoclonic activity may occur as a complication of gabapentin toxicity, especially with acute kidney injury or end-stage renal disease. We report 2 cases of myoclonic activity associated with gabapentin toxicity in the setting of renal disease which resolved with discontinuation of gabapentin and treatment with hemodialysis and peritoneal dialysis. As gabapentin has multiple indications and off-label uses, an understanding of myoclonus, neurotoxicity, and renal dosing is important to clinicians in multiple specialties.

Gabapentin (GBP), a pharmaceutical widely used for seizures and neuropathic pain, has emerged as a contaminant in global aquatic environments, raising concerns about its ecological impact. This study investigated the effects of environmentally relevant concentrations of GBP (0, 1, 10, 1000 μg/L) on visual development in zebrafish (Danio rerio). Behavioral assays showed that GBP exposure enhanced light sensitivity, as indicated by a significant increase in total travel distance (TTD) in all exposure groups compared to controls.

Peripheral nerve injuries (PNIs) are common, costly, and cause significant pain. Effective management of PNIs involves tailoring medications to the injury type as well as understanding the pharmacokinetics/pharmacodynamics to support nerve regeneration and reduce pain. Opioids act on opioid receptors to significantly reduce pain for many patients, but there are significant addiction risks and side effects.

Background: Gabapentin and pregabalin were originally introduced as anticonvulsant medications but are now also prescribed on- and off-label for multiple medical disorders, especially for pain management. The national opioid crisis has led to increased use of non-opioid pain medications, including gabapentinoids, which has been associated with changing patterns of adverse events associated with these medications. This study investigated the characteristics and trends of gabapentin and pregabalin exposures reported to US poison centers from 2012 to 2022.

Article Synopsis
- The study explores the neuroprotective effects of methanol extracts from two edible medicinal plants, Salix tetrasperma and Plantago asiatica, against rotenone-induced neurotoxicity in SH-SY5Y cells.
- Both plant extracts demonstrated antioxidant properties by reducing oxidative stress and improving survival of neurons affected by rotenone through various assays.
- LC-QTOF-MS analysis identified compounds with neuroprotective potential, suggesting these plants could be valuable sources for developing herbal nutraceuticals aimed at treating neurodegenerative diseases, such as Parkinson's.
