The fluorescence polarization immunoassay (FPIA) developed by Abbott to diagnose intoxication with tricyclic antidepressants was adapted for therapeutic drug monitoring and validated with chromatograpic methods to investigate its potential for this use. We compared serum concentrations of tricyclic antidepressants in vivo and in vitro obtained by FPIA with those by gas chromatography and HPLC. ...

The goals of this study were to determine whether the nonselective adenosine receptor antagonist caffeine exerts an analgesic effect and to investigate the time-dependent influence of the selective serotonin reuptake inhibitor clomipramine on the action of caffeine. Results suggest a possible interaction between serotonin and adenosine systems, which may contribute to the analgesic action of dr...

Quantitative review of the controlled treatment outcome literature for obsessive-compulsive disorder (OCD) showed that exposure with response prevention was highly effective in reducing OCD symptoms. Cognitive approaches were also found to be at least as effective as exposure procedures. It appears that both cognitive and exposure interventions involve some overlapping procedures and capitalize...

Tryptophan hydroxylase activity has been measured in synaptosomal preparations from rat brain. A significant circadian variation in enzyme activity was apparent in corpus striatum, (p < 0.001), brainstem and cortex (p < 0.01). A single dose of clomipramine or mianserin (20 mg/kg) had no effect on brainstem enzyme activity measured at mid-light or mid-dark. Chronic administration (7.5 mg/kg i.p....

vitamin b6 is a cofactor of various enzymes influencing numerous neurotransmitters in the brain such as norepinephrin, and serotonin . since these neurotransmitters influence mood , the aim the present work to evaluate the effect of vitamin b6 on depression and obsessive compulsive behavior when coadministred with clomipramine, fluoxetine, or venlafaxine. male mice weighing 25-30 g were used. t...

BACKGROUND Central serotonergic mechanisms appear to participate in the pathogenesis of recurrent neurally mediated syncope. The aim of the study was to investigate the responsiveness of the central serotonergic system by measuring the prolactin and cortisol responses to intravenous administration of the serotonin reuptake inhibitor clomipramine. METHODS AND RESULTS Twenty subjects free of an...

The mechanisms of involvement of the opioidergic system in the antinociceptive effect of antidepressants remain to be elucidated. The present study was designed to determine what type of opioid receptors may be involved at the spinal and supraspinal levels in the antihyperalgesic effect of clomipramine, a tricyclic antidepressant commonly prescribed in the treatment of neuropathic pain. Its ant...
