3H-imipramine binding in 39 drug-free patients with major depression and 44 healthy controls did not differ significantly between the two groups, in male or female subjects or in subgroups of depressed patients divided by endogenicity or dexamethasone suppression test result. 3H-imipramine binding in depressed patients drug-free for less than three weeks did not differ from those drug-free for ...

A binary mixture of imipramine HCl and chlordiazepoxide was determined by three different spectrophotometric methods. The first method involved determination of imipramine HCl and chlordiazepoxide using the simultaneous equations and the second method involved absorbance ratio method. Imipramine has absorbance maxima at 251 nm, chlordiazepoxide has absorbance maxima at 264.5 nm and isoabsorptiv...

The antiulcer effects of different tricyclic antidepressants (trimipramine, doxepin, imipramine, and amitriptyline) in comparison with those of cimetidine, pirenzepine and omeprazole were investigated in male rats with acute gastric ulcer. Acute gastric ulcer was induced by oral administration of O. 6N HCl solution, 1 mL/rat. Pretreatment of animals with doxepin, trimipramine, amitriptylin...

Caffeine is a marker drug for testing the activity of CYP1A2 (3-N-demethylation) in humans and rats. Moreover, it is also a relatively specific substrate of CYP3A (8-hydroxylation). In the case of 1-N- and in particular 7-N-demethylation of caffeine, apart from CYP1A2, other cytochrome P-450 isoenzymes play a considerable role. The aim of the present study was to investigate the influence of im...

AIMS In order to anticipate drug-interactions of potential clinical significance the ability of the novel antidepressant, venlafaxine, to inhibit CYP2D6 dependent imipramine and desipramine 2-hydroxylation was investigated in human liver microsomes. The data obtained were compared with the selective serotonin re-uptake inhibitors, fluoxetine, sertraline, fluvoxamine and paroxetine. Venlafaxine'...

Major circulating drug metabolites can be as important as the drugs themselves in efficacy and safety, so establishing methods whereby exposure to major metabolites following administration of parent drug can be predicted is important. In this study, imipramine, a tricyclic antidepressant, and its major metabolite desipramine were selected as a model system to develop metabolite prediction meth...

Alterations in brain activity patterns were assessed in response to swim stress by immunocytochemical detection of Fos-like immunoreactivity (Fos-LI) and high-resolution autoradiographic imaging of 14C-2-deoxyglucose (2-DG) uptake. The stress paradigm investigated was a classic behavioral screen for antidepressant drug activity, the forced swim test. One of the most pronounced effects produced ...

Background: Primary nocturnal enuresis is a common disorder that often leads to considerable distress in affected children and their family. In many countries pharmacologic therapy is preferred to non-pharmacologic behavioral and conditional alarm therapy. Imipramine, oxybutynin, and desmopressin have been used for enuresis with various efficacies. The aim of the present study was to compare th...

A total of 90 patients including 30 patients of generalized anxiety disorder and 30 of dysthymic disorder according to DSM III criteria plus 30 patients of mixed anxiety-depressive disorder were given a detailed psychiatric evaluation and four rating scales were made for measuring the level of anxiety and depression at intake and to record their improvement with treatment. Half the subjects in ...

Drug-induced immune thrombocytopenia (DITP), excluding heparin-induced thrombocytopenia, is relatively uncommon. It is characterized by drug-dependent antibodies that bind to the platelets and cause their destruction when the responsible drug is ingested or injected. Imipramine is a tricyclic antidepressant drug that is one of those used widely for primary enuresis nocturna, attention deficit h...
