Some statistically significant differences between citalopram and other antidepressants for the acute phase treatment of major depression were found in terms of efficacy , tolerability and acceptability .
Citalopram was more efficacious than paroxetine and reboxetine and more acceptable than tricyclics , reboxetine and venlafaxine , however , it seemed to be less efficacious than escitalopram .
BACKGROUND Recent US and UK clinical practice guidelines recommend that second-generation antidepressants should be considered amongst the best first-line options when drug therapy is indicated for a depressive episode .
Systematic review s have already highlighted some differences in efficacy between second-generation antidepressants .
Citalopram , one of the first selective serotonin reuptake inhibitors ( SSRI ) introduced in the market , is one of these antidepressant drugs that clinicians use for routine depression care .
OBJECTIVES To assess the evidence for the efficacy , acceptability and tolerability of citalopram in comparison with tricyclics , heterocyclics , other SSRIs and other conventional and non-conventional antidepressants in the acute-phase treatment of major depression .
An index of 5-HT synthesis changes during early antidepressant treatment: α-[11C]methyl-l-tryptophan PET study
The antidepressant selective serotonin transporter inhibitors ( SSRIs ) are clinical ly active after a delay of several weeks . Indeed , the rapid increase of serotonin ( 5-HT ) caused by SSRIs , stimulates the 5-HT(1A ) autoreceptors , which exert a negative feedback on the 5-HT neurotransmission . Only when autoreceptors are desensitized , can SSRIs exert their therapeutic activity . The 5-HT(1A ) receptor antagonist pindolol has been used to accelerate the clinical effects of antidepressant by preventing the negative feedback . Using the alpha-[(11)C]methyl-L-tryptophan/positron emission tomography ( PET ) , the goal of the present double-blind , r and omized study was to compare the changes in alpha-[(11)C]methyl-L-tryptophan trapping , an index of serotonin synthesis , in patients suffering from unipolar depression treated with the SSRI citalopram ( 20 mg/day ) plus placebo versus patients treated with citalopram plus pindol ( 7.5 mg/day ) .  PET and Hamilton depression rating scale ( HDRS-17 ) were performed at baseline , and after 10 and 24 days of antidepressant treatment . Results show that the combination citalopram plus pindol , compared to citalopram alone shows a more rapid and greater increase of an index of 5-HT synthesis in prefrontal cortex ( BA 9 ) . This research is the first human PET study demonstrating that , after 24 days , the combination SSRIs plus pindolol produces a greater increase of the metabolism of serotonin in the prefrontal cortex , an area associated to depressive symptoms
