We studied 21 patients with complex partial seizures during phenobarbital (PB) or primidone withdrawal. Blood levels were measured daily, and seizure frequency was monitored by nursing staff and EEG-video telemetry. Patients were monitored for one week of baseline and for five weeks after PB tapering was initiated (withdrawal). Most were observed for at least one week after levels were undetectable. When ranked seizure counts were averaged, there was a tendency for seizure rates to be highest as PB levels passed through the range 15 to 20 mg/l, compared with rates at higher or lower PB levels. There was little or no relation between the rate of PB withdrawal, other drug therapy, or initial PB level and the ratio of highest seizure frequency to mean seizure frequency. Patients withdrawing from PB may be most likely to experience an increase in seizure frequency when their PB blood level falls below 20 mg/l.

We reported a child with refractory partial seizures successfully managed by clinical desensitization to phenytoin. The patient had ischemic brain lesions due to cardiopulmonary arrest at 39 weeks of corrected age. He had complex partial seizures refractory to several antiepileptic drugs since 4 years of age. At 8 years 1 month of age, phenytoin was first administered. Fever and maculopapular rashes appeared at 10 days after phenytoin initiation, and then the drug was discontinued. At 8 years 8 months of age, desensitization was attempted because of refractoriness of seizures to drugs other than phenytoin. Desensitization was started at 1mg daily, and then the dose was doubled every week. His seizures were controlled by 150mg/day of phenytoin in combination with primidone. No problems have been observed during desensitization.

We compared a gas-chromatographic method for determination of phenytoin with a high-pressure liquid chromatographic technique and with enzyme immunoassay by three instrumental procedures. More than 100 sera from patients being treated with this drug were assayed by all these techniques. The coefficient of variation was the lowest (4.0%) with liquid chromatography, but all methods gave a CV of less than 10%. The correlation coefficients for all methods exceeded 0.97 when compared to gas chromatography. Operation costs varied with the number of tests per batch, reagent costs, and operator labor costs. All assays gave comparable values for the therapeutic range, so it would be plausible to use more than one method in a situation where (e.g.) satellite laboratories handle different quantities of assays. In any of these techniques, interferences from carbamazepine, mephenytoin, phenobarbital, and primidone were negligible.

Relationship between steady-state plasma concentrations of phenobarbitone (PB), phenytoin (PHT), primidone (PRM), carbamazepine (CBZ) and sodium valproate (VPA) and their efficacy and toxicity, were studied in 392 pediatric outpatients, long-term treated in monotherapy for epileptic seizures or febrile convulsions, in order to establish "target" values which may be used, as reference, in clinical practice. The concentration-efficacy and toxicity curves suggest target values of 20, 15, 9, 10, 6 and 70 mg/l for PB, PB derived from PRM, PRM, PHT, CBZ and VPA respectively. Above 25 mg/l of PB, 20 of PHT and 100 of VPA, markedly decreased the probability of response in refractory patients, and a clear increase in toxicity was shown. Above 7 mg/l of CBZ a decrease in the percentage of seizure-free patients was observed, without an increase of toxicity. For PRM no efficacy "ceiling" was found but side effects increased. The target values proposed may be helpful as a reference for the initial dosage of antiepileptic drugs in children, during monotherapy. Nevertheless, final doses should be adjusted according to clinical response of each patient.

Simultaneous nitrification/denitrification and trace organic contaminant (TrOC) removal during wastewater treatment by an integrated anoxic-aerobic MBR was examined. A set of 30 compounds was selected to represent TrOCs that occur ubiquitously in domestic wastewater. The system achieved over 95% total organic carbon (TOC) and over 80% total nitrogen (TN) removal. In addition, 21 of the 30 TrOCs investigated here were removed by over 90%. Low oxidation reduction potential (i.e., anoxic/anaerobic) regimes were conducive to moderate to high (50% to 90%) removal of nine TrOCs. These included four pharmaceuticals and personal care products (primidone, metronidazole, triclosan, and amitriptyline), one steroid hormone (17β-estradiol-17-acetate), one industrial chemical (4-tert-octylphenol) and all three selected UV filters (benzophenone, oxybenzone, and octocrylene). Internal recirculation between the anoxic and aerobic bioreactors was essential for anoxic removal of remaining TrOCs. A major role of the aerobic MBR for TOC, TN, and TrOC removal was observed.

Only one study met the inclusion criteria for the review. In this open study, 180 patients with newly-diagnosed, untreated epilepsy were randomised to treatment with the antiepileptic drug selected by their physician either with or without therapeutic drug serum level monitoring as an aid to dosage adjustments. The antiepileptic drugs used were carbamazepine, valproate, phenytoin, phenobarbital and primidone. A 12-month remission from seizures was achieved by 60% of the patients randomised to therapeutic drug monitoring (intervention group) and by 61% in the control group. A total of 56% in the intervention group and 58% in the control group were seizure free during the last 12 months of follow up. Adverse effects were reported by 48% in the intervention group and 47% of the control group patients. Of those randomised to therapeutic drug monitoring, 62% completed the two-year follow up compared with 67% of the control group.

Nicotinamide is a ligand of the benzodiazepine receptor and has been reported to have anticonvulsant activity. In addition, our previous clinical experience has raised the possibility that it may also potentiate the action of barbiturates. Therefore, we have examined the anticonvulsant activity and neurotoxicity of nicotinamide alone and in combination with phenobarbital in mice. Nicotinamide had its maximal anticonvulsant effect 15 min and its maximal sedative effect 45 min after intraperitoneal injection. At 15 min, the median effective dose was 586.5 mg/kg against bicuculline and 2,019 mg/kg against pentylenetetrazol. Nicotinamide was ineffective against maximal electroshock. It had a sedative effect, with a median toxic dose of 874.8 mg/kg by the Rotorod Toxicity Test at 45 min. At doses that were ineffective by themselves (0.01 effective dose) nicotinamide potentiated the anticonvulsant activity of phenobarbital against bicuculline and pentylenetetrazol, but the toxicity was not potentiated and therefore the therapeutic index of phenobarbital was improved by nicotinamide. These results suggest that nicotinamide may be useful as a therapeutic adjunct for the treatment of epilepsy with phenobarbital or primidone.

gamma-Aminobutyric acid (GABA) levels were determined in cisternal cerebrospinal fluid (CSF) of 19 epileptic dogs with generalized tonic-clonic (grand mal) seizures using a radioreceptor assay. Thirty-four healthy age-matched dogs served as controls. The average CSF GABA level in epileptic dogs (40 pmol/ml) was significantly lower than that determined in controls (66 pmol/ml). Treatment with phenobarbital or primidone seemed not to affect CSF GABA levels.

1. The pharmacokinetics and metabolism of primidone at steady-state were studied in 10 elderly patients aged 70-81 years and eight control subjects aged 18-26 years. 2. Primidone half-lives and clearance values (mean +/- s.d.) were similar in the elderly and in the young (12.1 +/- 4.6 vs 14.7 +/- 3.5 h and 34.8 +/- 9.0 vs 33.2 +/- 7.2 ml h-1 kg-1 respectively. 3. The serum concentrations of the metabolites phenylethylmalonamide (PEMA) and phenobarbitone relative to those of parent drug were higher in the elderly than in the young, the difference being significant (P less than 0.01) in the case of PEMA. 4. The renal clearances of primidone, phenobarbitone and PEMA were moderately decreased in the elderly but this reduction was statistically significant only for PEMA. Elderly patients excreted a reduced proportion of unchanged primidone and an increased proportion of PEMA in urine. 5. Ageing is associated with a greater accumulation of PEMA, which is unlikely to have a major clinical significance.

The antiepileptic activity of oral frusemide (120 mg daily) was compared with that of an identical placebo in a double-blind crossover trial in fourteen patients with severe focal epilepsy who were receiving long-term therapy with established antiepileptic drugs. A statistically significant reduction in the frequency of focal fits was seen with the active drug. Marked drowsiness occurred in three patients during frusemide therapy, causing their withdrawal from the trial. A slight, but significant, rise in serum phenobarbitone concentrations was observed during frusemide therapy, but no change was seen in serum primidone or phenytoin concentrations. Frusemide significantly lowered plasma sodium and potassium concentrations, and increased plasma bicarbonate.

25 microliters plasma, 25 microliters internal standard and 5 microliters sodium dihydrogenphosphate solution are extracted with 100 microliters ethyl acetate. 40 microliters of the extract are mixed with 10 microliters trimethyl-phenyl-ammoniumhydroxide (0.1 mol/l methanol). 3 microliters of this solution are injected for gas chromatography using a nitrogen-specific detector. Trimethyl-phenyl-ammoniumacetate appears to be a satisfactory methylating agent for these drugs in the injection port of the gas chromatograph.

The story began on 11th May 1857 when Charles Locock commented in the Lancet on his use of potassium bromide in 15 cases of "hysterical" epilepsy in young women. The next development was the serendipitous discovery of the anticonvulsant properties of phenobarbital by Alfred Hauptmann in 1912. This predated by more than 20 years the screening of potential therapeutic agents against "electrical seizures" in cats by Houston Merritt and Tracy Putnam. The result was the launching of phenytoin in 1938. Next came primidone, ethosuximide, carbamazepine and valproic acid, all of which can be regarded as first generation antiepileptic drugs (AEDs). Shortly after their synthesis, the benzodiazepines were rapidly recognised as having anticonvulsant activity. The modern era focused on the systematic screening of many thousands of compounds against rodent seizure models under the Anticonvulsant Drug Development Program in the US. This resulted in the global licensing, in chronological order, of vigabatrin, zonisamide, oxcarbazepine, lamotrigine, felbamate, gabapentin, topiramate, tiagabine, levetiracetam, pregabalin and lacosamide. Rufinamide is available in the US and Europe for Lennox-Gastaut syndrome and stiripentol has been made available for Dravet syndrome under the European orphan drug scheme. Eslicarbazepine can be prescribed in Europe for partial seizures, but not in the US. Has all this activity improved the lives of people with epilepsy? The short answer is-probably yes, but not by very much! This paper will conclude with a précis of the views of a selected group of paediatric and adult epileptologists on the advances in pharmacological management achieved over the last 20 years.

4 cases from the authors' experiences are added to the list of women who became pregnant during oral contraception while taking other drugs. 2 were 24- and 28-year-old epileptics taking Stediril and Mysoline, or primidone, a deoxybarbiturate. The 3rd was a 32-year-old woman who had forgotten 1 Stediril pill and taken 2 the next day, while taking 75 mg phenobarbital for a homeopathic regime. The 4th had been using Stediril for 5 years and had stopped for 2 months, and conceived during her 1st cycle after resuming the pill. She was taking drugs for migraine headaches, Nivaprine to prevent malaria, tetracyclines and trisulfazine for diarrhea. It is emphasized that when the usual pill side effects or regular withdrawal bleeding are absent in women on other medications, physicians should be alerted that the contraceptive action of the pill may be compromised.

A multi-residue method was developed that allows for the simultaneous determination of psychoactive compounds such as opioids, tranquilizers, antiepileptics (primidone, carbamazepine plus two metabolites),the cocaine metabolite benzoylecgonine, the antidepressant doxepin, as well as the calcium channel blocker verapamil in raw and treated wastewater, surface water, groundwater, and drinking water. After solid-phase extraction with Oasis HLB at neutral pH, the analytes were detected by LC electrospray tandem MS in the positive ion mode. With a few exceptions relative recoveries of the analytes exceeded 70%. The limits of quantification were in the low ng/L range. Matrix effects were compensated by using appropriate deuterated or 13C-15N-labeled surrogate standards. For raw and treated wastewater, concentration factors were lowered to reduce matrix effects. Most analytes (15 of 20) were found in raw and treated wastewater as well as in surface water, and hence, are presumably ubiquitously present in the environment. Antiepileptics, the opium alkaloids morphine and codeine, dihydrocodeine, the two tranquilizers oxazepam and temazepam, the opioid tramadol, doxepin, and verapamil were detected in STP discharges and German rivers at concentrations up to the microg/L range. In drinking water, only carbamazepine, its metabolite 10,11-dihydroxy-10,11-dihydrocarbamazepine, and primidone were present at concentrations up to 0.020 microg/L.

A rapid method for simultaneously determining the anticonvulsant drugs carbamazepine, ethosuximide, phenobarbitone, phenytoin, primidone, and valproic acid is described. Blank plus single-point calibration gives reliable quantitation from therapeutic to high fatal concentrations, except for ethosuximide, for which it gives semiquantitative results. Whole blood and liver tissue samples containing deuterated internal standards were extracted using Bond Elut Certify columns. Butyl derivatives were formed using n-iodobutane and TMAH under mild conditions and were extracted into ethyl acetate as a cleanup step. Recoveries were greater than 50%, except for valproic acid (42%). Sample preparation time was less than 2 h, and the GC run time was less than 20 min per injection. At least two ion pairs formed by electron impact ionization were monitored for each drug. Intraday CVs were less than 6.28% (4.20%) and interday CVs less than 14.1% (for midtherapeutic concentrations in blood [liver], except for ethosuximide). Linearity was observed from subtherapeutic to high fatal levels for all drugs. This method has been applied to forensic cases and has significantly reduced analytical time while improving case-work quality. Results of a case study involving anticonvulsant drugs are given.

The effectiveness and toxicity of phenobarbital (PB), primidone (PRM), and sodium valproate (VPA), used exclusively in monotherapy, were compared in 95 children affected with febrile convulsions. Treatment was restricted to either complicated or simple febrile convulsions with risk factors. The effectiveness and toxicity of each drug were related to the daily dose and the steady-state plasma levels. PB (4.8 +/- 0.7 mg/kg/day) achieved plasma levels of 16.4 +/- 2.8 micrograms/ml and prevented febrile convulsions in 80% of the patients. Side effects were observed in 76.7% of the patients, a change in dose being required only in 13.3%. PRM (17.8 mg/kg/day) yielded PB plasma levels of 14.1 +/- 3.7 micrograms/ml and was effective in 88.2% of the patients. The incidence of side effects was 53%, but no change in treatment was required. VPA (35.2 +/- 5.9 mg/kg/day) achieved plasma levels of 57.2 +/- 15.3 micrograms/ml (measured before the first dose in the morning) and was effective in 91.7% of the patients. Side effects were detected in 45% (significantly lower than after PB, p less than 0.01), and required a change in treatment in 14.3%. No differences in doses and plasma levels were found between patients with or without recurrence of febrile convulsions and with or without side effects; an exception was the higher doses of VPA administered to patients who showed side effects. It is concluded that PRM and VPA were at least as effective and well tolerated as PB. Because the plasma levels of the three drugs were near the lower limit of the therapeutic range, it remains to be elucidated whether higher doses may increase the benefit without adding unacceptable toxicity.

A 40-year-old woman with a history of substance abuse complicated by essential tremor and neuropathic pain was admitted to our addictions unit with altered mental state due to escalating use of alprazolam. Alprazolam had been prescribed several months prior to admission for treatment of anxiety. The doses had risen to 5-10 mg/day during that period. Apparently, her essential tremor had responded inadequately to propranolol, but had responded well to alprazolam. She was started on a sedative/hypnotic withdrawal protocol, but did not require treatment with phenobarbital. She subsequently rated her tremor as "moderately severe." On discontinuation of the withdrawal protocol, oxcarbazepine 450 mg twice daily was initiated to treat her neuropathic pain, and the tremor improved, with a clinically significant reduction in tremor and a decreased pain score.

Serum of normal volunteers and serum of epileptic patients receiving either a single drug or combined antiepileptic therapy with Phenytoin (Phen); Carbamazepine (Cbz); Primidone (Prim); Phenobarbital (Phb) were examined and showed: No differences with regard to total proteins, albumins and A/G ratio. The alpha 1-globulin fraction increased to 4.4% with Phen/Cbz (P less than 0.001) and decreased to 1.7% with Phen/Prim = (P less than 0.001). The alpha 2-globulins corresponded to 7.2% (P less than 0.001) with Phen/Prim and 15.5% (P less than 0.001) with Phen/Phb treatments. beta-Globulins decreased to 7.1% (P less than 0.05) when received Phen/Phb treatment. Low concentrations of serum gamma-Globulins were found in Phb (P less than 0.001), Prim (P less than 0.001, Phen (P less than 0.001) treated patients. However, with Cbz, Phen/Phb, Phen/Prim this electrophoretic fraction remained within the upper mysoline buy range of normal. IgA of patients treated with Phen showed a mean of 60 mg/dl.

A simple, sensitive and precise gas-chromatographic method for simultaneous extraction, derivatization and determination of methsuximide, ethosuximide, diphenylhydantoin, carbamazepine, phenobarbital and primidone in the presence of other drugs has been described. The method is especially useful for drug monitoring in patients on multiple anticonvulsant therapy while also on combination therapy with psychotropic drugs. It overcomes the analytical interferences between mephenytoin and phenobarbital; methsuximide and primidone; kemadrin and primidone; cholesterol and primidone; prolixin, haldol and other drugs; encountered in other methods using underivatized, trimethylsilylated or methylated drugs. As little as 0.5 microgram/ml of a drug can be determined and if needed the method can be scaled down to 0.3 ml plasma. The method yielded Triphala Churna Reviews recoveries of 97-103% with standard deviations of 0.7-1.8. For a constant check of the precision, an internal quality control using daily analysis of a sample from a frozen plasma pool supplemented with known concentrations of the anticonvulsants was used. The method is suitable for use in routine clinical laboratory.

Primidone is a minor first-generation antiepileptic drug, little currently prescribed for this indication, but except marketing authorization, remains a first-line treatment of essential tremor. Although it is metabolized in phenyl-ethyl-malondamide and phenobarbital, active metabolites that contribute also to its action, primidone is not a prodrug and is active by itself. The rate of conversion of primidone to phenobarbital is highly variable according to the subject. Generally accepted therapeutic range for primidone is between 5 and 10 mg/L (23-46 mmol/L). The therapeutic drug monitoring (TDM) of primidone must be accompanied by the determination of phenobarbital concentrations. The level of proof of the interest of the TDM primidone was estimated to be "probably useless". Phenobarbital, a very ancient anticonvulsant, is much less used Motilium 10mg Tablets today, for the benefit of other more recent compounds. It remains prescribed in neonatology and is one of the compounds used in status epilepticus. It is a molecule with a long half-life, metabolized in p-hydroxy-phenobarbital. It is a potent inducer of CYP3A4. Several side effects, especially drowsiness, are concentration-dependent. Generally accepted therapeutic range for phenobarbital is between 10 and 40 mg/L (43 - 172 mmol/L), without considering the type of crise. The level of proof of the interest of TDM of phenobarbital was evaluated as "recommended".

Until the early 1990s six major compounds (carbamazepine, ethosuximide, phenobarbital, phenytoin, primidone, and valproic acid) were available for the treatment of epilepsy. However, these drugs have pharmacokinetic limitations, teratogenic potential, and a negative effect on cognitive functions that impairs the quality of patients' lives and limits the use of these drugs in some patients. In addition, 20-30% of patients are refractory to these drugs.

The problem of phenytoin-induced gingival hyperplasia is dicussed within the context of consultative planning between oral care practitioners and the physician managing the epilepsy. The reluctance of the neurologist or of the patient to change an ongoing anti-convulsant program is often a response to a long history of tedious steps in medication adjustments to establish a level of seizure control without sacrificing alertness and mood control. Realistic indicators for discontinuing phenytoin are enumerated and therapeutic alternatives in treating phenytoin hyperplasia are discussed. A complicated case of seziure control is offered as an example of requirements in the medical control of epilepsy and the context in which periodontal therapy can be planned in conjunction with these medication adjustments. The mechanism of phenytoin induction of gingival hyperplasia is briefly discussed. Phenytoin (Dilantin) and a newer agent, valproic acid (Depakene), are compared as alternatives in seizure control.

We present a new high pressure liquid chromatography (HPLC) method for the simultaneous analysis of primidone, phenobarbital, phenytoin, and carbamazepine in serum. The chromatographic separation is carried out using an Altex model 110-A pump, a 250 times 4.6 mm column containing 5 mum Spherisorb ODS particles and a variable wavelength ultraviolet detector set at 197 nm. The mobile phase is a mixture of acetonitrile, distilled water, and 1.75 M phosphoric acid (27:72.8:0.2). The flow rate is 1.5 ml/min, and the analysis time is 17 min. A 200 mul aliquot of serum is buffered at pH 5 and extracted with dichloromethane. The extract is evaporated to dryness and dissolved in methanol for chromatographic analysis. Cyclopal is used as the internal standard and quantification is achieved using peak height ratios. This HPLC method is evaluated for precision and accuracy with reference to the EMIT system. The least-squares regression analysis of comparison data for the drugs shows a favorable correlation. Also, a paired t-test indicates no significant difference for the HPLC and EMIT values for primidone, phenobarbital, phenytoin, and carbamazepine. From this study we conclude that this HPLC method could be successfully used for the simultaneous therapeutic monitoring of the four anticonvulsants.

Serum samples from 335 epileptic patients receiving one or more anticonvulsant drugs, phenobarbitone, primidone and phenytoin, have been analysed for biochemical liver profile (BLP) and serum drug concentration. The results show that the induction of serum gamma glutamyltransferase (GGT) is affected by the sex and age of the patient, type of anti-convulsant drug prescribed and duration of treatment. It is less affected by serum drug concentration. It is suggested that these factors must be considered when interpreting results involving serum GGT activity as the index of microsomal enzyme induction.

Two men, aged 57 and 77 years old, reported increasing unsteadiness on standing upright for the past 2 and 5 years, respectively. It had become impossible for them to remain standing for more than 10 seconds, as otherwise they might fall down. Walking, sitting and lying were possible without difficulty. Both patients were found to have a fine tremor in both legs on standing only. There were no other neurological signs or symptoms. Electromyography of the leg muscles demonstrated tremor activity at 14-16 Hz. Propranolol, 40 mg three times daily, in the 57-year-old patient brought no improvement. However, on taking primidone, in slowly increasing doses up to 250 and 500 mg daily, respectively, the condition lastingly improved in both patients.

Odd ratio for CBZ induced SJS/TEN and HLA-B*15:02 was 609.0 (95% CI: 23-15873; p=0.0002). Molecular modeling studies showed that acetazolamide, ethosuxiamide, lamotrigine, oxcarbazepine, phenobarbital, phenytoin, primidone and sodium-valproate may induce ADR in HLA-B*15:02 carriers alike CBZ. Conclusion. We confirmed HLA-B*15:02 as a predictor of SJS/TEN and recommend pre-screening. Computational prediction of DIHR is useful in personalized medicine.

The antiepileptic activity of oral frusemide (120 mg daily) was compared with that of an identical placebo in a double-blind crossover trial in fourteen patients with severe focal epilepsy who were receiving long-term therapy with established antiepileptic drugs. A statistically significant reduction in the frequency of focal fits was seen with the active drug. Marked drowsiness occurred in three patients during frusemide therapy, causing their withdrawal from the trial. A slight, but significant, rise in serum phenobarbitone concentrations was observed during frusemide therapy, but no change was seen in serum primidone or phenytoin concentrations. Frusemide significantly lowered plasma sodium and potassium concentrations, and increased plasma bicarbonate.

Packed-column supercritical fluid chromatography (pSFC) coupled to an atmospheric pressure chemical ionization (APCI) source and a tandem mass spectrometer (MS/MS) for rapid and simultaneous determination of clozapine, ondansetron, tolbutamide and primidone in in vitro samples was developed in support of metabolic stability experiments. The effects of the eluent flow-rate and composition as well as the nebulizer temperatures on the ionization efficiency of the analytes in positive ion mode under normal phase pSFC conditions were studied. The metabolic stability of the test drug components through microsomal incubation by the proposed pSFC-APCI/MS/MS approaches requiring approximately 1 min per samples were evaluated with respect to specificity, durability and accuracy. These metabolic stability results obtained by pSFC-MS/MS methods are in a good agreement with those obtained by fast high-performance liquid chromatography/tandem mass spectrometry (HPLC-MS/MS) method.

The antiepileptic drug primidone is to be withdrawn from sale by January 2004. After this date, the drug will still be available for a time, but only on a limited basis. Most primidone users are elderly patients who have been prescribed this drug for many years. Changing to a new drug constitutes a health risk for them. If primidone treatment is discontinued too quickly, withdrawal seizures may appear, some of which may be severe. In patients who have not suffered an epileptic seizure for many years, discontinuing medication may be considered. Whenever continuation of anticonvulsive treatment is desirable, it may probably be a good idea to switch over to some newer antiepileptic drug. If a simple and quick substitution is essential, primidone may be replaced by its main metabolite: phenobarbital. General practitioners and neurologists are strongly advised to alter patients' medication in good time.

The frequency of epileptic seizures was observed in a controlled therapeutic trial on 23 epileptic inpatients before and after treatment with vitamin D(2) or placebo in addition to anticonvulsant drugs. The number of seizures was reduced during treatment with vitamin D(2) but not with placebo. The effect was unrelated to changes in serum calcium or magnesium. The results may support the concept that epileptics should be treated prophylactically with vitamin D.

Levels of alpha 1-acid glycoprotein (alpha 1-AGP) were determined in 40 epileptic patients who had been also treated with carbamazepine (CBZ) and, in some patients, phenobarbital (PB) for at least 3 months. alpha 1-AGP levels were also determined in 28 controls. CBZ dit not alter blood levels of alpha 1-AGP while CBZ-PB decreased them. Such results are at variance with recent studies which suggested an increase of alpha 1-AGP in epileptic patients treated either with phenytoin or phenytoin + PB, or + CBZ, or + primidone.

Despite the trend towards single drug therapy of epilepsy, patients resistant to monotherapy are commonly treated with more than one antiepileptic drug. As part of an investigation on the experimental background for antiepileptic drug combinations, the effect of the pharmacodynamic interactions between carbamazepine and phenobarbital on the toxicity/efficacy ratio was studied in mice. All results were expressed in terms of drug concentrations in the brain to exclude possible pharmacokinetic interactions from the analysis. A purely additive interaction was found for the anticonvulsant as well as for the neurotoxic effect of the drugs. The combination of carbamazepine and phenobarbital has therefore no advantage over each drug alone in this model. Based on these and previous results, there is no experimental evidence in favor of any combination between the four main drugs against partial seizures, i.e., carbamazepine, phenytoin, phenobarbital, and primidone.

A rapid gas-liquid chromatographic method has been developed for the analysis of phenobarbitone, primidone and phenytoin in small (50 microliter) volumes of either blood plasma or serum. Neither solvent transfer nor evaporation are required in the extraction, which takes less than 3 min to complete, and a quantitative analysis may be performed, in duplicate, within 20 min. Sources of interference in the assay are minimal, and prior treatment of the column with gamma-glycidoxypropyltrimethoxysilane facilitates the measurement of as little as 10 ng of underivatized drug "on-column" using a flame-ionisation detector. The method has proved valuable when used for detection and measurement of these three compounds at concentrations of 2 mg/1 or greater.

We reported a child with refractory partial seizures successfully managed by clinical desensitization to phenytoin. The patient had ischemic brain lesions due to cardiopulmonary arrest at 39 weeks of corrected age. He had complex partial seizures refractory to several antiepileptic drugs since 4 years of age. At 8 years 1 month of age, phenytoin was first administered. Fever and maculopapular rashes appeared at 10 days after phenytoin initiation, and then the drug was discontinued. At 8 years 8 months of age, desensitization was attempted because of refractoriness of seizures to drugs other than phenytoin. Desensitization was started at 1mg daily, and then the dose was doubled every week. His seizures were controlled by 150mg/day of phenytoin in combination with primidone. No problems have been observed during desensitization.

The prevalence of peripheral neuropathy in 186 epileptic patients was 16.7%. The neuropathy was characterized by stocking hypesthesia and reduced Achilles reflexes, and it occurred with all anticonvulsant agents. Electrophysiologic tests indicated slowing of peroneal and sural nerve conduction velocity and prolongation or absence of H reflexes and F responses. The prevalence of neuropathy was not greater in patients receiving phenytoin, and there was no relationship between clinical or electrical abnormalities and blood levels or duration of treatment for either phenytoin or phenobarbital. We did not find a specific relationship between phenytoin usage and peripheral neuropathy in epileptic patients.
