Comparative Study Clinical Trial
Comparison of the steady-state pharmacokinetics of topiramate and valproate in patients with epilepsy during monotherapy and concomitant therapy.
The steady-state pharmacokinetics of valproate (VPA) and topiramate (TPM) were compared during VPA monotherapy, concomitant VPA and TPM therapy, and TPM monotherapy to evaluate pharmacokinetic interactions. ⋯ Because changes in TPM and VPA pharmacokinetics were small, it is unlikely that their concomitant use will have a significant impact on the clinical condition of the patient.

Because several reports have described the relation between epilepsy and cardiac arrhythmias and suggest that changes in autonomic neural control of the heart could be involved in the pathogenesis of sudden unexplained death in patients with epilepsy, the aim of this study was to evaluate cardiac function in patients with temporal lobe epilepsy. ⋯ These findings suggest that the spectral analysis of RR variability may detect disorders of autonomic cardiac control in patients with epilepsy, even in the absence of abnormal findings during ECG monitoring. This alteration, which is more severe in cases with right EEG focus, could play a role in the pathogenesis of cardiac arrhythmias.

Don't test, do sell: legal implications of inclusion and exclusion of women in clinical drug trials.
This article explores the historic underpinnings of the exclusion of women from clinical drug trials, identifies recent developments, and examines legal implications for women with epilepsy and for others. Distinguishing stakeholders and their interests may lead to policies that better serve all. Past and present statutory, regulatory, and judicial frameworks were reviewed, as well as legal, medical, and historical commentary. ⋯ At this time the most effective shields will involve procurement of informed consent as well as testing of both women and men. In the long run, tort, health care, and regulatory reform will best serve all interested persons. Inclusion of women in clinical drug trials has become a how question, not an if one.

Standard antiepileptic drugs (AEDs) are associated with a wide variety of acute and chronic adverse events and with many interactions with each other and with non-AEDs that complicate patient management. The safety and interaction profiles of the newer AEDs have also been intensively studied. Safety data are available for six of the newer AEDs, lamotrigine (LTG), vigabatrin (VGB), gabapentin (GBP), tiagabine (TGB), felbamate (FBM), and topiramate (TPM). The potential for the most recently developed AEDs for producing rare idiosyncratic reactions cannot be ascertained until additional patient exposures have been reported from careful postmarketing surveillance.
