in this study, the effect of α-adrenoceptor agents on imipramine-induced antinociception was investigated using formalin test. intraperitoneal (i.p.) administration of imipramine at different doses (10-80 mg/kg) induced antinociception in both phases of formalin test. in addition, intracerebroventricular (i.c.v.) injection of imipramine (1, 5, and 10 µg/rat) did not elicit any effect, although ...

high-performance liquid chromatography (hplc) methods employing ultraviolet (uv) detector are not sufficiently sensitive to measure the low plasma concentrations following single oral dose of imipramine. therefore, in the present study a simple, rapid and yet sensitive hplc method with uv detection was developed and validated for quantitation of imipramine in human plasma samples. an efficient ...

Thirty-seven severely-disabled agoraphobics were randomly assigned to (1) Imipramine-no exposure. (2) Imipramine + exposure or (3) Placebo + exposure groups. To provide a more stringent test of the pharmacological effects of imipramine independent of exposure to phobic stimuli, Ss in the Imipramine-no exposure condition received antiexposure instructions during the first 8 weeks of therapy. Ass...

Recent preclinical and clinical data indicate beneficial role of zinc in the antidepressant treatment. To evaluate the mechanism of interaction between zinc and antidepressants, in the present study we examined the brain zinc, imipramine and desipramine concentrations in mice treated with combinations of zinc and imipramine and subjected to the forced swim test. We have chosen doses of zinc (10...

Plasma membrane vesicles isolated from porcine blood platelets take up approximately 8 to 15 pmol of [3H]imipramine per mg of membrane protein. This apparent binding requires Na+ in the external medium and is reversed by 5-hydroxytryptamine and fluoxetine. The apparent KD for imipramine uptake is 23 nM, which agrees well with the KI for competitive inhibition of 5-hydroxytryptamine transport by...
