What this trial studies

This observational study evaluates the effectiveness and safety of intravenous lacosamide as a rescue treatment for acute pain in patients with trigeminal neuralgia presenting to the emergency department. Conducted at Hospital Universitari de Bellvitge, the study will enroll approximately 20 patients over two years, assessing pain response using a Numerical Pain Rating Scale at various time points. The study aims to provide insights into the potential benefits of lacosamide for patients experiencing severe facial pain that is resistant to conventional therapies.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years diagnosed with classical or idiopathic trigeminal neuralgia experiencing acute pain exacerbations.

Not a fit: Patients with contraindications to lacosamide or those unable to provide informed consent due to mental illness or language barriers may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new option for patients suffering from acute pain exacerbations of trigeminal neuralgia.

How similar studies have performed: While evidence for intravenous treatments in acute trigeminal neuralgia is limited, previous studies have suggested potential benefits of similar approaches, making this investigation both relevant and necessary.
