This compendium represents what we believe to be the most current and reliable pharmacological data on anticonvulsant drugs. The information presented is derived from determinations of the drugs in plasma or serum by gas--liquid chromatography in studies of the efficacy of anti-epileptic agents. We present information on the limitations of therapeutic concentration ranges, half-lives, active an...

A comparison of the anticonvulsant and neurotoxic effects of cannabidiol (CBD), delta 9tetrahydrocannabinol, cannabinol and antiepileptic drugs (phenytoin, phenobarbital, carbamazepine, chlordiazepoxide, clonazepam, ethosuximide and trimethadione) was made in rats. Median effective potencies (ED 50 values) for maximal electroshock, audiogenic seizures and TD50 values for a rotor rod neurotoxici...

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 follo...

Height and stage of puberty of 67 children with epilepsy were measured before beginning treatment with anticonvulsant drugs and annually to a maximum five years' treatment. Blood concentrations of the drugs used (phenytoin, sodium valproate, carbamazepine, ethosuximide, and phenobarbitone) were monitored throughout. No significant deviation in growth patterns was detected.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome associated with anticonvulsant drugs is a rare but potentially life-threatening disease that occurs in response to arene oxide producing anticonvulsant such as phenytoin and carbamazepine. There have been many reports of cross reactivity among the anticonvulsants upon first exposure to the offending drugs. However, there has bee...

WHAT IS KNOWN AND OBJECTIVE Antiepileptic drugs often produce serious adverse effects, and many patients do not respond to them properly. Phytocannabinoids produce anticonvulsant effects in preclinical and preliminary human studies, and appear to produce fewer adverse effects than available antiepileptic drugs. The present review summarizes studies on the anticonvulsant properties of phytocanna...

BACKGROUND Anticonvulsant properties have been attributed to extracts of the herbal medicine Valeriana officinalis. Our aims were to examine the anticonvulsant properties of valerenic acid and valerian extracts and to determine whether valerian preparations interact with the activity of other anti-epileptic drugs (phenytoin or clonazepam). To achieve these goals, we validated the adult zebrafis...
