Almost 50 years after its discovery, valproic acid remains a mainstay in the treatment of epilepsy, both alone and in combination with other anticonvulsants. It is also associated with a hyperammonemic encephalopathy, when used in combination with other drugs. We present a case of valproate-induced hyperammonemic encephalopathy in a patient on multiple anticonvulsant and psychotropic medication...

Sodium valproate and tomato extract have been studied in different experimental models of epilepsy individually. The aim of the present study was to evaluate the effect of lycopene on the antiepileptic effects of sodium valproate against pentylenetetrazol-induced kindling in mice. Swiss albino mice of either sex were randomly divided into 5 groups, with each group containing 8 mice. These group...

Prenatal exposure to sodium valproate (VPA), a widely used anti-epileptic drug, is related to a series of dysfunctions, such as deficits in language and communication. Clinical and animal studies have indicated that the effects of VPA are related to the concentration and to the exposure window, while the neurobehavioral effects of VPA have received limited research attention. In the current stu...

OBJECTIVE Pituitary tumours occurring in patients bilaterally adrenalectomized because of Cushing's disease (Nelson's syndrome) are frequently invasive and a complete their resection is not possible in most of them. Administration of the drugs decreasing ACTH secretion could be helpful in such unresectable tumours. We tried to evaluate the influence of somatostatin and valproic acid, compared t...

Introduction Valproic acid (VPA, Valproate) is an eight-branch fatty acid and varies from other antiepileptic drugs. VPA use might lead to mild to severe hepatotoxicity. The aim of this study was to investigate valproic acid impact on liver transaminases at the beginning of VPA treatment and after three and six months of it. Materials and Methods This study was designed as a cross sectional pro...

An 11-year-old girl with juvenile neuronal ceroid lipofuscinosis developed acute pancreatitis secondary to valproic acid treatment, which resolved after discontinuation of the medication and conservative treatment. To my knowledge, this is the first reported case of neuronal ceroid lipofuscinosis with valproate-associated pancreatitis. Children with neuronal ceroid lipofuscinosis may be suscept...

Migraine is a common and incapacitating neurologic disorder manifesting with episodic moderate to a severe headache and other symptoms such as photophobia, phonophobia, nausea, and vomiting. Triptans and ergot compounds have been used as treatment options for an acute migraine headache for many years. Triptans are considered the first line of treatment in patients with moderate to a severe migr...

The impact of replacing divalproex sodium with valproic acid on patient outcomes and direct drug costs was studied. Before-and-after medical chart review was performed in a state-supported facility for mentally retarded adults in which a pharmacy and therapeutics (P&T) committee recommended replacement of divalproex with valproic acid. Patients were studied if they had received divalproex for a...

Absolute pitch, the ability to identify or produce the pitch of a sound without a reference point, has a critical period, i.e., it can only be acquired early in life. However, research has shown that histone-deacetylase inhibitors (HDAC inhibitors) enable adult mice to establish perceptual preferences that are otherwise impossible to acquire after youth. In humans, we found that adult men who t...

RATIONALE Valproic Acid is a commonly used psychiatric drug primarily used as a mood stabilizer. Mild hyperammonemia is a Valproic Acid common adverse effect. This report presents an example of treated hyperammonemia on Valproic acid therapy managed with L-carnitine administration in BD patients characterized by sudden vulnerability. PATIENT CONCERNS We report the case of a 29-year-old man su...
