BACKGROUND: Elevated nitric oxide (NO) levels in the brain have been apparently associated with depression in kindled animals. Owing to the major role of neuronal nitric oxide synthase (nNOS) in brain and ineffectiveness of antiepileptic drugs (AEDs) in restoring nitrosative stress, the present study was envisaged to evaluate the adjuvant nNOS inhibitor, 7-nitroindazole (7-NI) with valproic acid for combined treatment of epilepsy and associated depression. METHODS: Pentylenetetrazole kindled animals associated with depression were treated with vehicle, valproate (300mg/kg/day ip), valproate with 7-NI (10mg/kg; 20mg/kg; 40mg/kg)/day ip and 7-NI (40mg/kg/day ip) for 15days...

: Migraine with aura is a subtype of migraine consisting of neurological disturbances that usually precede headache. Cortical spreading depression (CSD) is the likely pathophysiological correlate of the aura phase of migraine, found in common and rare forms of migraine, such as familial hemiplegic migraine (FHM). CSD is a depolarization wave that propagates across the cerebral gray matter transiently suppressing neuronal activity. Prophylactic treatments for migraine, such as topiramate (TPM) or valproate (VPA), reduce the number of CSD events...

OBJECTIVE: Whether new antiepileptic drugs (AEDs) may result in neuropathy is unknown but possible given their effects on vitamin metabolism. This analysis aimed to determine frequency and correlates of neuropathy in subjects treated with new AEDs in relation to drug used, length of exposure and serum vitamin B12 and folate levels. METHODS: We performed a cross-sectional study of 52 consecutive epileptic subjects. Presence of neuropathy was determined using the Utah Early Neuropathy Score (UENS)...

Two novel series of 3,4-dihydroisoquinolin with heterocycle derivatives (4a-t and 9a-e) were synthesized and evaluated for their anticonvulsant activity using maximal electroshock (MES) test and pentylenetetrazole (PTZ)-induced seizure test. All compounds were characterized by IR, ¹H-NMR, (13)C-NMR, and mass spectral data. Among them, 9-(exyloxy)-5,6-dihydro-[1,2,4]triazolo[3,4-a]isoquinolin-3(2H)-one (9a) showed significant anticonvulsant activity in MES tests with an ED50 value of 63.31 mg/kg and it showed wide margins of safety with protective index (PI > 7...

Predictive in vitro test methods addressing the parameters relevant to drug release in the pediatric gastrointestinal tract could be an appropriate means for reducing the number of in vivo studies in children. However, dissolution models addressing the particular features of pediatric gastrointestinal physiology and typical pediatric dosing scenarios have not yet been described. The objective of the present study was to combine the knowledge on common vehicle types and properties and current information on pediatric gastrointestinal physiology to design a dissolution model that enables a biorelevant simulation of the gastrointestinal conditions in young children...

Aim The physical health of people with mental health conditions is often suboptimal, and in many cases this may be related to their prescription medicines. One issue is that patients are monitored inconsistently for adverse drug reactions (ADRs). The aim of this study was to explore whether the nurse-led West Wales Adverse Drug Reaction (WWADR) Profile for Mental Health Medicines could improve recognition and management of ADRs in a crisis resolution home treatment service. Method The WWADR Profile was implemented in addition to usual care, in a one-group 'before and after' comparison study (n=20)...

Paradoxical sleep deprivation in rats is considered as an experimental animal model of mania endowed with face, construct, and pharmacological validity. We induced paradoxical sleep deprivation by placing rats onto a small platform surrounded by water. This procedure caused the animal to fall in the water at the onset of REM phase of sleep. Control rats were either placed onto a larger platform (which allowed them to sleep) or maintained in their home cage. Sleep deprived rats showed a substantial reduction in type-2 metabotropic glutamate (mGlu2) receptors mRNA and protein levels in the hippocampus, but not in the prefrontal cortex or corpus striatum, as compared to both groups of control rats...

BACKGROUND: Recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) has a poor prognosis and the combination of cisplatin and cetuximab, with or without 5-fluorouracil, is the gold standard treatment in this stage. Thus, the concomitant use of novel compounds represents a critical strategy to improve treatment results. Histone deacetylase inhibitors (HDACi) enhance the activity of several anticancer drugs including cisplatin and anti-Epidermal Growth Factor Receptor (anti-EGFR) compounds...

BACKGROUND: Many people with schizophrenia do not achieve a satisfactory treatment response with ordinary antipsychotic drug treatment. In these cases, various add-on medications are used, and valproate is one of these. OBJECTIVES: To examine whether:1. valproate alone is an effective treatment for schizophrenia and schizoaffective psychoses; and2. valproate augmentation of antipsychotic medication is an effective treatment for the same illnesses. SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials (July 2002; February 2007; July 2012; March 04, 2016)...

G Munch, N Godart
INTRODUCTION: Adolescence is a unique phase of the human developmental process. In adolescents, psychotropic medications may have different efficacy and tolerance profiles compared to those at other stages of the lifespan. Mood stabilizers are a complex pharmacological category including lithium, some anticonvulsants, and some second generation antipsychotics. Focusing on this class of pharmacological agents, we aim to answer the following questions: in which indications and according to which modalities should mood stabilizers be prescribed during adolescence? METHODS: Information was sought from the websites of the French Haute Autorité de santé (HAS) and Agence nationale de sécurité du médicament et des produits de santé (ANSM), the American Food and Drug Administration (FDA) and the British National Institute for Health and Clinical Excellence (NICE)...

BACKGROUND: Valproic acid (VPA) is prescribed therapeutically for multiple conditions, including epilepsy. When taken during pregnancy, VPA is teratogenic, increasing the risk of several birth and developmental defects including neural tube defects (NTDs). The mechanism by which VPA causes NTDs remains controversial and how VPA interacts with folic acid (FA), a vitamin commonly recommended for the prevention of NTDs, remains uncertain. We sought to address both questions by applying untargeted metabolite profiling analysis to neural tube closure (NTC) stage mouse embryos...

BACKGROUND: Mood stabilizers like lithium and anticonvulsants are used in bipolar and related psychotic disorders. There is a lack of knowledge of the relationship of these medications and cognition in the psychosis spectrum. We studied the association between serum concentration of mood stabilizers and cognitive performance in a well-characterized sample of bipolar and schizophrenia spectrum disorders. METHODS: Serum concentrations of valproate, lamotrigine, and lithium were analyzed for associations to performance on neuropsychological tests in six cognitive domains in individuals with bipolar disorder (n = 167) and in a combined sample of individuals with bipolar or schizophrenia spectrum disorders (n = 217)...

Epilepsy is the most common neurological disorder affecting approximately 50 million people worldwide. In India, overall prevalence of epilepsy is reported to be 5.59/1000 population. Antiepileptic drugs (AEDs) constitute the main-stay of treatment with a large number of AEDs available in the market. High incidence of adverse effects is a major limitation with AEDs. One of the major concerns is significant metabolic effects on the bone. However, little attention has been paid to this issue because most of the bone effects remain subclinical for a long time and may take years to manifest clinically...
