What this trial studies

This clinical study aims to evaluate the safety of combining Pentoxifylline and Celecoxib in patients suffering from Grand-Mal Epilepsy who are currently treated with Phenytoin monotherapy. The study focuses on understanding the effects of these medications on neuroinflammation, which is a significant factor in the development of epilepsy. Participants will be monitored for any adverse effects and overall safety during the treatment period. The study is designed for adults aged 18 and older who meet specific inclusion criteria.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with Grand-Mal Epilepsy currently treated with Phenytoin monotherapy.

Not a fit: Patients with significant liver or kidney function abnormalities, those with a history of substance abuse, or those currently using other antiepileptic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective treatment option for patients with Grand-Mal Epilepsy.

How similar studies have performed: While the specific combination of Pentoxifylline and Celecoxib in this context is novel, previous studies have explored the role of neuroinflammation in epilepsy treatment with varying degrees of success.
