What this trial studies

This open-label, randomized control trial evaluates the efficacy and tolerability of sublingual dexmedetomidine compared to oral lorazepam for treating agitation in hospitalized patients with schizophrenia or bipolar disorder. A total of 32 participants will be randomized to receive either dexmedetomidine or lorazepam based on their level of agitation, as measured by the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). The study will assess outcomes at multiple time points to determine the effectiveness of the treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-55 who are hospitalized and experiencing moderate to severe agitation due to schizophrenia or bipolar disorder.

Not a fit: Patients who are pregnant, breastfeeding, or have certain medical conditions such as severe hepatic impairment or active pulmonary disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new, effective option for managing agitation in patients with schizophrenia or bipolar disorder.

How similar studies have performed: While the use of dexmedetomidine for agitation is being explored, this specific approach is relatively novel and has not been extensively tested in similar studies.
