Generalized action myoclonus associated with escitalopram in a patient with mixed dementia.

摘要

Escitalopram is the S-stereoisomer of citalopram and a selective serotonin reuptake inhibitor (SSRI). Studies have shown that escitalopram and citalopram produce different effects, possibly because of a lack of contrasting action for R-citalopram. However, side effects are quite similar for the 2 drugs and certainly include serotonin toxicity and other effects.-We report the case of 78-year-old woman presenting with generalized action myoclonus possibly related to escitalopram intake. Her medical history was significant for coronary disease treated with percutaneous coronary intervention with stenting, previous cholecystectomy, previous isteroannessiectomy for endo-metrial cancer, insulin-dependent diabetes, hypertension, nonalcoholic hepatic steatosis, and previous left hemispheric transient ischemic attack.
