What this trial studies

This study evaluates the effects of ibuprofen and nifedipine on post-seizure symptoms in patients with epilepsy. Following seizures, blood flow to the brain is significantly reduced, which may lead to neurological deficits. The study will involve 90 subjects who will be randomly assigned to receive either ibuprofen, nifedipine, or a placebo. The goal is to determine if these medications can prevent the negative consequences of reduced blood flow after seizures.

Who should consider this trial

Good fit: Ideal candidates are individuals over 16 years old with frequent seizures occurring more than once a week.

Not a fit: Patients with multiple seizure onset zones or contraindications to the study medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this could lead to improved management of postictal symptoms in epilepsy patients.

How similar studies have performed: Animal studies have shown promising results with similar approaches, but this is a novel application in humans.
