Background: Agitation is a frequent and challenging symptom in schizophrenia and bipolar disorder, characterized by heightened motor activity, emotional distress, and potential aggression. This symptom is most observed during acute episodes, representing a significant burden on patients, caregivers, and healthcare systems. Agitation is a leading cause of emergency department visits and psychiatric hospitalizations, necessitating prompt and effective interventions to ensure safety and mitigate its far-reaching impact. Traditional treatments, including high-potency antipsychotics and benzodiazepines, remain first-line options but are associated with significant drawbacks such as sedation, extrapyramidal symptoms, tolerance, and limited applicability in certain patient populations, especially those with respiratory or cardiac depression and the elderly. Non-pharmacologic strategies like de-escalation techniques and environmental modifications are invaluable but may be impractical in acute care settings, as speed and efficiency are critical in emergent settings. These limitations, including the onset of extrapyramidal symptoms with high-dose antipsychotics and the development of tolerance with benzodiazepines, highlight gaps in care, including the need for faster-acting, safer, and more patient-friendly alternatives that reduce reliance on physical restraints and invasive interventions.
Methods: This review explores the evolution of treatments for agitation, focusing on alternative and innovative approaches. To highlight these treatments, an extensive review of the literature was conducted utilizing PubMed, Google Scholar, Embase.com, and other search engines.
Results: Key developments include sublingual dexmedetomidine, recently FDA-approved, which offers sedation without respiratory depression and a non-invasive administration route. Similarly, subcutaneous olanzapine provides a more convenient alternative to intramuscular injections, reducing injection-related complications. Other emerging treatments such as gabapentin, pregabalin, and ketamine show promise in addressing agitation in specific contexts, including comorbid conditions and treatment-resistant cases. A comparative analysis of these therapies highlights their mechanisms of action, clinical evidence, and practical challenges.
Conclusions: Future directions emphasize intranasal delivery systems, novel pharmacologic agents, and potential roles for cannabinoids in managing agitation. These innovations aim to balance rapid symptom control with improved patient safety and experience. The set back with these emerging techniques is a lack of standardized dosing and protocols. They also face ethical concerns, including the chance of misuse or abuse, as well as regulatory barriers, as they lack FDA approval and their legality changes between states. This review underscores the clinical, practical, and ethical considerations in advancing care for agitated patients, paving the way for more effective and compassionate management strategies in psychiatric settings.
