Combination of Olanzapine and Samidorphan Has No Clinically Significant Effect on the Pharmacokinetics of Lithium or Valproate
ConclusionsConsistent with previously reported findings on olanzapine, administration of multiple doses of OLZ/SAM did not have a clinically significant effect on the pharmacokinetics of lithium or valproate. Co-administration of OLZ/SAM and lithium or valproate was generally well tolerated; the safety profile of OLZ/SAM was consistent with that observed in previous clinical studies.

Divalproex sodium regulates ataxin-3 translocation likely by an importin α1-dependent pathway
Nuclear localization of ataxin-3 plays a fundamental role in seeding aggregation and the pathology of spinocerebellar ataxia type 3 (SCA3). However, very few compounds that are able to modulate the nuclear transport of ataxin-3 have been identified. In our previous study, we found that divalproex sodium (DVS) reduced heat shock-induced nuclear localization of ataxin-3. However, the mechanism of DVS in the translocation of ataxin-3 still remains unknown. There is accumulating evidence that importins are regulated by acetylation, and histone deacetylase inhibitors can interrupt this process. With this in mind, we used cells ...

Pharmacologic Prevention of Migraine: A Narrative Review of the State of the Art in 2018.
Abstract This paper describes current non-antibody pharmacologic approaches to the prevention of migraine in adults. Preventive therapy should be considered for patients with migraine who routinely have more than 6 headache days per month or in other special circumstances. Choices for preventive therapy are based on patient preferences about side effects and evidence of efficacy. The evidence level and commonly used doses for selected categories of migraine preventive medication are reviewed, including antiepileptic drugs, antihypertensive drugs, and antidepressants. Propranolol, timolol, topiramate, and divalproe...

Determinants of free serum valproate concentration: A prospective study in patients on divalproex sodium monotherapy
ConclusionsAn increase in the total VPA concentration results in corresponding linear and non-linear rise in the VPA free fraction and free VPA concentration, respectively. The total daily dose of VPA should be increased in smaller increments whenever a total VPA concentration of 60 μg/mL is reached. When drug monitoring is needed, we recommend measuring the free VPA concentration. If this test is unavailable, and for patients with normal albumin levels, it can be predicted from the total VPA concentration using the generated equation. (Source: Seizure)

Time Course of Reversal of Valproate-Mediated Inhibition of Lamotrigine
Conclusions These observations demonstrate that the pharmacokinetic interaction between LTG and VPA is reversible, and that de-inhibition appears to follow a predictable time course. Complete offset, or reversal of this interaction takes place 10–14 days after VPA discontinuation. Our data also confirms the observation that LTG oral clearance may be inhibited by very low concentrations of VPA. These data support the conversion algorithm suggested by the manufacturer, and provide guidance to the clinician. These data provide clinically useful information in developing a dosing algorithm for converting patients to LT...

Remission of Psychosis in Treatment-resistant Schizophrenia Following a Seizure: A Case Report
Discussion Improvement in our patient’s mental state was very drastic and very closely temporally associated with the occurrence of the seizure. Clozapine-induced seizures are known to occur, as clozapine decreases the seizure threshold, and the cumulative one-year risk of seizure is about five percent. In our patient, the dose of clozapine was high and there was no other comorbid medical or neurological condition that could explain the seizure, leading us to the conclusion that the seizure was caused by clozapine. ECT has been effective in improving patients on clozapine, and as ECT is based on the mechanism of s...

WITHDRAWN: Anticonvulsant drugs for migraine prophylaxis.
CONCLUSIONS: Anticonvulsants appear to be both effective in reducing migraine frequency and reasonably well tolerated. There is noticeable variation among individual agents, but there are insufficient data to know whether this is due to chance or variation in true efficacy. Acetazolamide, clonazepam, lamotrigine and vigabatrin were not superior to placebo (one trial each). Relatively few robust trials are available for agents other than sodium valproate/divalproex sodium and topiramate; gabapentin in particular needs further evaluation. Trials designed with sufficient power to compare different drugs are also necessary. ...

DISCUSSION: Since the blind has not been broken on either of these clinical trials, conclusions about the maintenance effectiveness of either VPA or Li+ in youths with bipolar disorder type 1 or 2 cannot be made yet. Similarly, it is unclear whether VPA is superior to placebo in genetically high-risk youths with cyclotaxia.

Cross section comparative study for comorbid migraine and major depression in epileptic patients: demographic, clinical, electroencahpalograhy and therapeutic implications
Conclusion: It is important to address comorbidity in treating patients with epilepsy. The diagnosis of atypical migraine symptoms can be quite difficult, in such cases EEG may be useful. Some antiepileptic drugs (AEDs) like divalproex sodium (valproate) and topiramate are effective in preventing migraine attacks, while others including phenytoin, oxcarbazepine, vigabatrin and clonazepam, are not effective in migraine prophylaxis. The antiepileptic drugs most closely associated with depression on initiation of treatment are vigabatrin, phenobarbitone, and topiramate.Further research on the nature and causes of the co-morbi...

The effect of antidepressants and antipsychotics on weight gain in children and adolescents
In conclusion, prescribing of SSRIs and SNRIs may be associated with improvements in weight status in children and adolescents but trials assessing their use in obesity, outside of established psychiatric illness, are limited and still experimental. Youth prescribed antipsychotic medication should be monitored for exaggerated weight gain and in those where obesity is a pre‐existing concern agents other than olanzapine, clozapine and risperidone may be advantageous.

Divalproex sodium enhances the anti-leukemic effects of imatinib in chronic myeloid leukemia cells partly through SIRT1
Imatinib (IM) represents a breakthrough in the treatment of chronic myeloid leukemia (CML) by inhibiting the activity of Bcr-Abl tyrosine kinase. However, many patients exhibit resistance to IM in the clinic. Recent studies have indicated that sirtuin 1 (SIRT1), a class III histone deacetylase (HDAC), plays an important role in leukemogenesis. In addition, some HDAC inhibitors are being tested to determine their anti-cancer activities in clinical trials. Divalproex sodium (DVPX), a first-line treatment for epilepsy, is also a HDAC inhibitor. (Source: Cancer Letters)
