Serotonin syndrome-A focused review

Area of Science:

• Pharmacology
• Toxicology
• Clinical Medicine

Background:

• Serotonin syndrome is a potentially life-threatening condition resulting from overstimulation of serotonin receptors by serotonergic drugs.
• The increasing use of serotonergic medications, particularly selective serotonin reuptake inhibitors, likely contributes to a rise in serotonin syndrome cases.
• The exact incidence of serotonin syndrome is difficult to determine due to its varied clinical presentation.

Purpose of the Study:

• To offer a clinically oriented review of serotonin syndrome.
• To cover pathophysiology, epidemiology, clinical signs, diagnosis, differential diagnosis, and treatment.
• To classify serotonergic drugs and their mechanisms, emphasizing the pharmacological context for detection and management.

Main Methods:

• A focused literature review was conducted.
• The PubMed database was utilized for the literature search.

Main Results:

• Serotonin syndrome can arise from therapeutic use, overdose of a single drug, or interactions between multiple serotonergic agents.
• Key clinical features include neuromuscular excitation, autonomic dysfunction, and altered mental status.
• These symptoms typically appear in patients with recent changes in serotonergic drug therapy.

Conclusions:

• Early recognition and prompt treatment of serotonin syndrome are essential to minimize patient morbidity.
• Understanding the pharmacological basis is critical for managing this condition effectively.
