Citalopram conditioning

Since the introduction of the first approved SSRI, fluoxetine (1) in 1987 [9], a number of SSRIs have been developed for the treatment of depression [2], Currently, the five most commonly prescribed SSRIs are fluoxetine, escitalopram (2, S-enantiomer of citalopram), sertraline (3), paroxetine (4) and fluvoxamine (5). Recent effort in the clinical development of new SSRIs has focused on the treatment of premature ejaculation (PE) by taking advantage of the ejaculation-delaying side effects of SSRIs [10]. Although SSRIs have been prescribed off-label to treat this condition, an SSRI with rapid onset of action and rapid clearance could be preferred for on-demand treatment of PE [11,12]. Dapoxetine (LY210448, 6), an... 

Treatment of psychiatric complications should generally be along standard lines for the respective conditions. Some syndromes appear to be brief and self-limiting once ecstasy use stops, but a more chronic course may also be seen, with cases in the literature of psychoses which prove resistant to treatment (Vecellio et al. 2003). Whichever psychiatric syndrome occurs, there is possibly a theoretical indication for specific serotonergic re-uptake inhibitors such as fluoxetine, sertraline or citalopram, given the effect of ecstasy in reducing serotonin transmission. This would purely be a pragmatic approach which has not yet been properly tested, and it may be that the transmission abnormalities are not amenable to this kind of enhancement. 

The earliest and unfortunately still one of the commonest treatments of social phobia is self-medication with alcohol. The behaviorally disinhibiting actions of alcohol allow many social phobics to engage in social contacts that would otherwise be impossible. Legitimate therapeutic drugs for social phobia are now being discovered at a fast pace (Fig. 9—7). In fact, one of the SSRIs (paroxetine) already has been formally approved for use in the treatment of social phobia, and several other SSRIs and antidepressants are rapidly accumulating evidence of their efficacies in this condition as well. Specifically, studies of all five SSRIs (paroxetine, fluvoxamine, fluoxetine, sertraline, and citalopram) have indicated their efficacy in social phobia. Currently, SSRIs are considered first-line treatments for social phobia. 

Under basal conditions, 5-HT2C / mice demonstrated immobility levels in the tail suspension test that are comparable to wild-type mice. However, they exhibited enhanced responding to fluoxetine (43). Additional experiments revealed that the SSRI citalopram and the 5-HT2B/2C receptor antagonist SB 206553 given in combination to wild-type mice decreased immobility in...
