Key result
Serotonin syndrome, caused by serotonergic drugs, presents with neuromuscular excitation, autonomic dysfunction, and altered mental status, requiring early clinical recognition to prevent morbidity.
Why the study?
With the increasing use of serotonergic drugs, cases of serotonin syndrome have likely increased, yet its true incidence remains unknown due to diffuse clinical presentation.
Early clinical recognition of serotonin syndrome, characterized by neuromuscular excitation, autonomic dysfunction, and altered mental status, is crucial to prevent significant morbidity.
Background: Serotonin syndrome is a potentially life-threatening syndrome with manifestations spanning from mild adverse effects to life-threatening toxicity. The syndrome is caused by overstimulation of serotonin receptors by serotonergic drugs. Since the use of serotonergic drugs is increasing, primarily due to the widespread use of selective serotonin reuptake inhibitors, cases of serotonin syndrome have likely seen a parallel increase. The true incidence of serotonin syndrome remains unknown due to its diffuse clinical presentation. Objectives: This review aims to provide a clinically focused overview of serotonin syndrome, covering its pathophysiology, epidemiology, clinical manifestations, diagnostic criteria, differential diagnosis, and treatment as well as classifying serotonergic drugs and their mechanism of action. The pharmacological context is emphasized, as it is crucial for detection and management of serotonin syndrome. Methods: Focused review based on a literature search using the PubMed database. Findings and conclusion: Serotonin syndrome can occur through therapeutic use or overdose of a single serotonergic drug, or as a drug interaction between two or more serotonergic drugs. Central clinical features consist of neuromuscular excitation, autonomic dysfunction and altered mental status, occurring in a patient undergoing new or altered serotonergic therapy. Early clinically recognition and treatment are crucial to prevent significant morbidity.
