PURPOSE In developing countries, availability and quality of drugs are critical factors for effective management and control of epilepsy. This study investigated the availability and costs of antiepileptic drugs (AEDs), and the quality of phenobarbital in Vientiane Municipality, Lao PDR. METHODS In March 2004, we enrolled all pharmacies (categories I and II) of four central districts of Vient...
Phenobarbital induces liver cytochrome P-450 b,e proteins mainly by increasing the rate of transcription of these genes. The mechanism responsible for the phenobarbital increment in the rate of transcription of cytochrome P-450 b,e genes is unknown. The objective of this study was to assess whether active protein synthesis was needed for phenobarbital to induce the liver cytochrome P-450 b,e ge...
Phenobarbital and other xenobiotics induce drug-metabolizing enzymes, including glutathione S-transferase A1/A2 (rGSTA1/A2). We examined the mechanism of induction of rGSTA1/A2 in rat livers after phenobarbital treatment. The induction of rGSTA1/A2 was not uniform across the hepatic lobule; steady-state transcript levels were threefold higher in perivenous hepatocytes relative to periportal hep...
35 epileptic patients, aged 10 to 58 years (mean 23), who were taking anticonvulsant drugs were studied. The patients exhibited a 34% reduction in serum calcium levels, a 41 % increase in serum alkaline phosphatase activity and a slight but insignificant decrease in serum phosphate, compared to untreated controls. These changes appear to be related to the anticonvulsant drug taken, in the ...
This paper critically reviews the current literature and evidence on diagnosis, classification, clinical approach, management of neonatal seizures. A stepwise approach for treatment seizures is presented. In a recent randomized controlled trial comparing phenobarbital to levetiracetam as first-choice anti-seizure medication with primary outcome seizure free 24 h, former was found superior (80% ...
objective studies on the effect of various antiepileptic drugs on serum lipids show contradictory results. we aimed to find the effect of phenobarbital and sodium valproate monotherapy on serum lipid profile and liver function tests in epileptic children. materials & methods this cohort study was conducted in amirkola children hospital. one hundred and ten children with epilepsy were included i...
objective the aim of this study was to evaluate and compare the effects of na valproate and phenobarbital on changes in the weight of epileptic patients following treatment for their condition using the drugs mentioned. materials and methods sixty epileptics were assigned into two groups of 30 patients each, the case and controls. the diagnosis was made on the basis of the international league...
objective(s): the aim of the present study is to determine the effect of chloramphenicol (cap) on rat liver and small intestine. effect of phenobarbital (pb) on cap toxicity was also investigated. materials and methods: rats were received cap at doses of 0, 200, 400 and 600 mg/kg. another group was pretreated with 80 mg/kg pb 30 min prior to administration of various doses of cap. the exper...
controlled release swellable tablets of phenobarbital were prepared by a simple direct compression process using hydroxypropyl methylcellulose (hpmc) as the matrix former. the effects of the viscosity grades of hpmc and hpmc/lactose ratio and ethylcellulose (ec)/sodium carboxymethylcellulose (nacmc) and their concentrations on the release behavior of phenobarbital from hpmc matrices were invest...
OBJECTIVE To compare efficacy and safety of treatment with phenobarbital or bromide as the first-choice antiepileptic drug (AED) in dogs. DESIGN Double-blinded, randomized, parallel, clinical trial. ANIMALS 46 AED-naïve dogs with naturally occurring epilepsy. PROCEDURES Study inclusion was based on age, history, findings on physical and neurologic examinations, and clinicopathologic test ...
