Measuring lorazepam blood levels in adults treated for catatonia
Blood Concentration in Lorazepam and Treatment in Adult Catatonia
This research will measure lorazepam blood levels in adults with catatonia to see if those levels relate to how well the medication works.

What this trial studies
This is an observational study enrolling adults diagnosed with catatonia per DSM-5 who are treated with lorazepam. Blood samples will be taken to measure lorazepam concentrations while clinical dosing and symptom response are recorded. No experimental interventions are given; treatment follows usual clinical care and researchers correlate blood levels with remission and side effects. The goal is to describe relationships between dose, blood concentration, and clinical outcome.
Who should consider this trial
Good fit: Adults (18+) diagnosed with catatonia according to DSM-5 who are receiving lorazepam and willing to provide blood samples are ideal candidates.
Not a fit: People under 18, pregnant patients, those not treated with lorazepam, or individuals unwilling to participate are unlikely to receive benefit from this project.
Why it matters
Potential benefit: If successful, findings could help clinicians personalize lorazepam dosing to improve remission rates and reduce side effects in catatonia.
How similar studies have performed: While lorazepam is a well-established effective treatment for catatonia, using measured blood concentrations to guide dosing is relatively untested and mostly unexplored.
