Given the distinctive characteristics of both epilepsy and antiepileptic drugs (AEDs), therapeutic drug monitoring (TDM) can make a significant contribution to the field of epilepsy. The measurement and interpretation of serum drug concentrations can be of benefit in the treatment of uncontrollable seizures and in cases of clinical toxicity; it can aid in the individualization of therapy and in adjusting for variable or nonlinear pharmacokinetics; and can be useful in special populations such as pregnancy. This review examines the potential for TDM of newer AEDs such as eslicarbazepine acetate, felbamate, gabapentin, lacosamide, lamotrigine, levetiracetam, perampanel, pregabalin, rufinamide, retigabine, stiripentol, tiagabine, topiramate, vigabatrin, and zonisamide...

BACKGROUND: Essential tremor is one of the most common movement disorders. Treatment primarily consists of pharmacological agents. While primidone and propranolol are well-established treatments in clinical practice, they may be ineffective in 25% to 55% of patients and can produce serious adverse events in a large percentage of them. For these reasons, it is worth evaluating the treatment alternatives for essential tremor. Some specialists have suggested that pregabalin could be a potentially useful agent, but there is uncertainty about its efficacy and safety...

TRP channels have been discovered as a specialized group of somatosensory neurons involved in the detection of noxious stimuli. Desensitization of TRPV1 located on dorsal root and trigeminal ganglia exhibits analgesic effect and makes it potential therapeutic target for treatment of neuropathic pain. With this background, the present study was aimed to investigate the protective effect of niflumic acid, a TRPV1 modulator, on stavudine (STV)-induced neuropathic pain in rats. Stavudine (50 mg/kg) was administered intravenously via tail vein in rats to induce neuropathic pain...

OBJECTIVES: To assess efficacy and safety of once-daily controlled-release (CR) formulation of pregabalin in patients with postherpetic neuralgia (PHN). METHODS: A randomized withdrawal trial, with 6-week single-blind pregabalin treatment phase and 13-week double-blind phase, where patients with ≥50% decrease in mean pain score at single-blind end point from baseline were randomized (1:1) to pregabalin CR (82.5-660 mg d) or placebo. Primary efficacy outcome was time to loss of therapeutic response (LTR; <30% decrease in weekly mean pain score from single-blind baseline or discontinuation due to adverse event [AE] or lack of efficacy)...

Injuries to the adult CNS often result in permanent disabilities because neurons lose the ability to regenerate their axon during development. Here, whole transcriptome sequencing and bioinformatics analysis followed by gain- and loss-of-function experiments identified Cacna2d2, the gene encoding the Alpha2delta2 subunit of voltage-gated calcium channels (VGCCs), as a developmental switch that limits axon growth and regeneration. Cacna2d2 gene deletion or silencing promoted axon growth in vitro. In vivo, Alpha2delta2 pharmacological blockade through Pregabalin (PGB) administration enhanced axon regeneration in adult mice after spinal cord injury (SCI)...

Diagnosing neuropathic pain and distinguishing it from nociceptive pain can be challenging, but is essential because both forms of pain require different treatment strategies. The diagnosis of neuropathic pain is primarily based on clinical findings. Therefore, a careful, focused history and an examination of the signs characteristic of neuropathic pain are crucial. Imaging techniques and electrophysiological examinations, as well as punch skin biopsy can support the clinical diagnosis. Ideally, treatment should be individualized using a mechanism-based approach...

Herpes zoster, also known as shingles, is a distinctive clinical condition caused by the reactivation of latent varicella zoster (chickenpox) virus following an initial infection. Approximately 1 million cases of herpes zoster occur annually in the US, and one in every three people develops herpes zoster during their lifetime. Postherpetic neuralgia is a neuropathic pain syndrome characterized by pain that persists for months to years after resolution of the herpes zoster rash. It stems from damage to peripheral and central neurons that may be a byproduct of the immune/inflammatory response accompanying varicella zoster virus reactivation...
