Fluoxetine hydrochloride is the first agent of the class of antidepressants known as selective serotonin-reuptake inhibitors (SSRIs). Fluoxetine is a racemic mixture of the R- and S- enantiomers and are of equivalent pharmacologic activity. Despite distinct structural differences between compounds in this class, SSRIs possess similar pharmacological activity. As with other antidepressant agents, several weeks of therapy may be required before a clinical effect is seen. SSRIs are potent inhibitors of neuronal serotonin reuptake. They have little to no effect on norepinephrine or dopamine reuptake and do not antagonize α- or β-adrenergic, dopamine D2 or histamine H1 receptors. During acute use, SSRIs block serotonin reuptake and increase serotonin stimulation of somatodendritic 5-HT1A and terminal autoreceptors. Fluoxetine is marketed under the trade names Prozac and Sarafem among others. It is also marketed for
the treatment of premenstrual dysphoric disorder (Sarafem®, fluoxetine hydrochloride). PROZAC is a selective serotonin reuptake inhibitor indicated for:
• Acute and maintenance treatment of Major Depressive Disorder (MDD)
in adult and pediatric patients aged 8 to 18 years
• Acute and maintenance treatment of Obsessive Compulsive
Disorder (OCD) in adult and pediatric patients aged 7 to 17 years
• Acute and maintenance treatment of Bulimia Nervosa in adult patients
• Acute treatment of Panic Disorder, with or without agoraphobia, in adult
patients.
Studies at clinically relevant doses in man have demonstrated that fluoxetine blocks the uptake of serotonin into human
platelets. Studies in animals also suggest that fluoxetine is a much more potent uptake inhibitor of serotonin than of norepinephrine.
Antagonism of muscarinic, histaminergic, and α1-adrenergic receptors has been hypothesized to be associated with various
anticholinergic, sedative, and cardiovascular effects of classical tricyclic antidepressant (TCA) drugs. Fluoxetine binds to these and
other membrane receptors from brain tissue much less potently in vitro than do the tricyclic drugs.
