Key result
Serotonergic drugs trigger serotonin syndrome with neuromuscular excitation, autonomic dysfunction, and altered mental status.
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 and treatment of serotonin syndrome, characterized by neuromuscular excitation, autonomic dysfunction, and altered mental status, are crucial to prevent significant morbidity.
Supports early recognition to prevent morbidity in serotonergic drug users; confirms established features without advancing new evidence.
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 the 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 clinical recognition and treatment are crucial to prevent significant morbidity.

Mikkelsen et al. (2023) conducted a review in Serotonin syndrome. Serotonergic drugs was evaluated. Serotonin syndrome, caused by overstimulation of serotonin receptors by serotonergic drugs, presents with neuromuscular excitation, autonomic dysfunction, and altered mental status.
