Even though cultural, biological and health service factors influence the tolerance and acceptability of psychotropic drugs in different settings, there is a lack of data on the use of antidepressants in primary care settings from India. The aim of this study was to examine the tolerance of 3 models of antidepressants treatments (fluoxetine 20 mg; imipramine 75 mg; imipramine 150 mg) for common...

Nicotine-induced ATP secretion from chromaffin cells was blocked by imipramine and desipramine. This blocking action took place on both, fast and slow, components of ATP secretion. Exposure of chromaffin cells to nicotine (10 microM) for 4 s induced an inward current of about -155 pA. Imipramine and desipramine blocked, in a concentration-dependent manner, both peak inward current and total cha...

Sir, Long term administration of psychotropic drugs produces significant biochemical changes, that often become manifest only after their withdrawal. Various clinical syndromes described are : rebound insomnia following benzodiazepene withdrawal (Kale et al., 1980), mania after imipramine withdrawal (Gupta et al., 1986) and hypomania following lithium withdrawal (Gupta, 1987). Such a process ma...

1. Uptake studies using radioactive octopamine have revealed that the larval lantern of the Photuris firefly possesses a concentrative, high-affinity uptake system for octopamine. This compound has been shown previously to be the neurotransmitter of the photomotor neurones. 2. Imipramine is a potent inhibitor of the uptake of octopamine in the lantern. At 10~moll~', it reduces specific uptake o...

I N RECENT YEARS more and more drugs have become implicated as causes of thrombocytopenia. In many instances correlations were made from clinical reports, and occasionally in vitro methods have demonstrated the presence of antibodies specific for a certain drug.1’2 In the present paper two cases were studied in which in vitro methods suggested that thrombocytopenia was induced by desipramine (P...

We previously reported that adrenocorticotropic hormone (ACTH)-treated rats serve as a valuable animal model for tricyclic antidepressant-resistant depressive conditions. The present study was undertaken to investigate the changes in neurogenesis in the hippocampus of ACTH-treated rats. Chronic treatment of ACTH decreased the number of bromodeoxyuridine-labeled cells in the dentate gyrus, and t...

We have isolated 145 fertile mutants of C. elegans that are defective in egg laying and have characterized 59 of them genetically, behaviorally and pharmacologically. These 59 mutants define 40 new genes called egl. for egg-laying abnormal. Most of the other mutants are defective in previously identified genes. The egl mutants differ with respect to the severity of their egg-laying defects and ...

The efflux of antimony through multidrug resistance protein (MDR)-1 is the key factor in the failure of metalloid treatment in kala-azar patients infected with antimony-resistant Leishmania donovani (Sb(R)LD). Previously we showed that MDR-1 upregulation in Sb(R)LD infection is IL-10-dependent. Imipramine, a drug in use for the treatment of depression and nocturnal enuresis in children, inhibit...

This study investigated the effect of the serotonin selective reuptake inhibitors (SSRIs) fluoxetine, sertraline, fluvoxamine and the tricyclic antidepressant (TCA) impiramine on oxidative stress in brain and liver induced by lipopolysaccharide administration in mice. Each drug was administered subcutaneously at doses of 10 or 20 mg/kg, for two days prior to intraperitoneal (i.p.) administratio...

OBJECTIVES To assess the efficacy and safety of hypericum extract (STEI 300, Steiner Arzneimittel, Berlin) compared with imipramine and placebo in patients in primary care with a current episode of moderate depression. DESIGN Randomised, double blind, multicentre, parallel group trial for 8 weeks. SETTING Trained panel of 18 general practitioners from four German states: Bavaria, Berlin, Rh...
