Serotonin and suicidality: the
impact of fluoxetine administration. II: Acute neurobiological
effects.

Medicine, New Haven, CT, USA.
Despite the demonstrated
anti-depressant efficacy of the selective serotonin reuptake inhibitors
(SSRIs), increased suicidal ideation and/or agitation have been reported
in a small proportion of individuals receiving fluoxetine or other
SSRIs. Part II of this review examines fluoxetine's acute effects on
serotonergic functioning. Although acute fluoxetine administration
produces a short-term compensatory decrease in the firing of 5-HT
neurons, the neurobiological data reviewed suggests that this decrease
probably does not lead to an over-compensatory net decrease in 5-HT
functioning. The implications of fluoxetine's complex effects on the
5-HT systems are discussed with respect to clinical practices and future
research.
