Citalopram 사용 후 발생한 각성시 이갈이 2예

Two Cases of Citalopram Induced Awake Bruxism

  Bruxism has been defined as an oral parafunctional activity characterized by clenching, bracing, gnashing and grinding of teeth while asleep and or awake. While bruxism has been associated with a number of neurological diseases, it has been mostly highlighted following drug medication. We report 2 female patients of awake bruxism after citalopram medication. The bruxism in these patients was completely or significantly improved after cessation of citalopram. We discuss the pathophyisological mechanism of bruxsm associated with selective serotonin reuptake inhibitors (SSRIs). These cases highlight that bruxism can occur in response to citalopram, as do in other SSRIs. (Korean J Psychopharmacol 2006;17(2):233-237)
