HART, LARRY G., ANTHONY M. GUARINO, AND RICHARD H, ADAMSON. Effects of phenobarbital on biliary excretion of organic acids 2*lz male and female rats. Am. J. Physiol. 2 17( 1) : 46-52. 1969.-The effects of phenobarbital pretreatment on the biliary excretion of four organic anions, indocyanine green (ICG), chlorothiazide (CTZ), phenol red, and probenecid, were investigated. Indocyanine green and ...
Phenobarbital produces its anti-epileptic actions by increasing the inhibitory drive of γ-aminobutyric acid. However, following recurrent seizures, γ-aminobutyric acid excites neurons because of a persistent increase of chloride raising the important issue of whether phenobarbital could aggravate persistent seizures. Here we compared the actions of phenobarbital on initial and established ictal...
The inhibition of gap junctional intercellular communication (GJIC) is a common effect of nongenotoxic carcinogens and might be a biomarker for these agents. To further test this relationship, we hypothesized that phenobarbital would inhibit mouse hepatocyte GJIC and this would correlate with strain-specific hepatocarcinogenicity. Phenobarbital is a strong nongenotoxic hepatocarcinogen in B6C3F...
discussion early recognition of dress syndrome is of a particular importance. although rare, in newborn infants with the presence of skin rash, liver involvement, hyper-eosinophilia and lymphadenopathy, dress diagnosis should be highly suspected and prompt intervention including withdrawal of causative drug is required to prevent potentially fatal outcomes. introduction drug rash with eosinophi...
OBJECTIVE Phenobarbital increases electroclinical uncoupling and our preliminary observations suggest it may also affect electrographic seizure morphology. This may alter the performance of a novel seizure detection algorithm (SDA) developed by our group. The objectives of this study were to compare the morphology of seizures before and after phenobarbital administration in neonates and to dete...
Single enteral loading dose of phenobarbital for achieving its therapeutic serum levels in neonates.
AIM To investigate whether therapeutic serum drug levels may be achieved with a single enteral loading dose of phenobarbital. METHODS The study was performed at the Mersin University Hospital in Turkey between April 2004 and August 2006, and included 29 newborn babies with seizure. After the acute treatment of the seizure with midazolam at a dose of 0.1 mg/kg, phenobarbital was administered b...
Despite the development of successive generations of antiepileptic drugs, phenobarbital has retained a unique position in the therapeutic armamentarium and is still the most widely prescribed treatment for epilepsy worldwide. Although serious systemic side effects of phenobarbital are uncommon, its potential neurotoxicity remains a major concern. This is particularly so in the developed world. ...
The suprachiasmatic nucleus (SCN) controls the timing of the preovulatory luteinizing hormone (LH) surge in laboratory rodents. Barbiturate administration during a critical period on proestrus delays the surge and prolongs the estrous cycle 1 day. Because a nonphotic timing signal (zeitgeber) during the critical period that phase advances activity rhythms can also induce the latter effect, we h...
Orodispersible tablets, usually prepared using freeze-drying method, are becoming a popular drug formulation for patients who have difficulties swallowing solid dosage forms. The influence of drug solubility and concentration on the physical characteristics of lyophilized tablets composed of mannitol and gelatin was investigated. Phenobarbital and phenobarbital sodium were studied as model drug...
Adult cycling female rats were hemispayed and administered with 7.5 mg phenobarbital/100 gm body weight for 15 days. 5IU FSH or FSH+LH per 100 gm body weight was administered from day 13 to 15 to the hemispayed phenobarbital treated rats. Phenobarbital inhibits the ovarian compensatory hypertrophy significantly and increases the cholesterol and lipid levels in the ovary. Administration of FSH a...
