Substantial evidence has accumulated that spinally projecting serotonergic neurons modulate nociception. However, the exact receptor subtypes that mediate the antinociceptive response of serotonin within the spinal cord continue to be a subject of debate. Therefore, we explored the effect of serotonergic system on imipramine induced antinociception by using 5-Hydroxytryptamine-3 (5HT3) receptor...

A simple and rapid reversed phase-high performance liquid chromatographic method was developed for simultaneous determination of imipramine hydrochloride and diazepam in pharmaceutical formulations. The elution was done in isocratic mode utilizing a mobile phase consisting of methanol:water:0.1M sodium acetate (30:50:20 v/v/v) on Chromosil C18 column with a flow rate of 1.0 ml/min and with dete...

Alprazolam is an anti-anxiety drug shown to be effective in the treatment of depression. In this study, the effect of sympathetic receptor antagonists on alprazolam-induced antidepressant action was studied using a mouse model of forced swimming behavioral despair. The interaction of three sympathetic receptor antagonists with benzodiazepines, which may impact the clinical use of alprazolam, wa...

CONTEXT Panic disorder (PD) may be treated with drugs, psychosocial intervention, or both, but the relative and combined efficacies have not been evaluated in an unbiased fashion. OBJECTIVE To evaluate whether drug and psychosocial therapies for PD are each more effective than placebo, whether one treatment is more effective than the other, and whether combined therapy is more effective than ...

Depression, a bewildering and burdensome illness, is one of the commonest psychiatric diseases. It is expected to be the second leading contributor to Global Disease Burden by 2020. The objective of the study was to determine the effect of nifedipine on the responses of imipramine, sertraline and furosemide in the forced swim test (FST) and tail suspension test (TST) in mice. Groups of mice wer...

OBJECTIVE This study was designed to compare the efficacy of two two-phase pharmacological treatment strategies for inpatients with DSM-IV major depressive disorder. METHOD During phase I, patients participated in a double-blind study of the effects of imipramine versus fluvoxamine, with final evaluation of response 4 weeks after patients attained the target plasma level. In phase II, for pat...

Converging lines of evidence indicate the involvement of nicotinic acetylcholine receptors in depressive illness and antidepressant drug action. We investigated the effects of sub-chronic and chronic treatment with imipramine, nicotine and their combination on: (a) the ability of a dopamine-mimetic challenge to produce locomotor stimulation and (b) cortical density of beta-adrenoceptors. One we...

Imipramine hydrochloride was administered to five male horses (400-500 kg b.wt.): one experienced young stallion, two mature normal breeding stallions, one 5-year-old stallion with erection and ejaculatory dysfunction, and one long-term castrated male horse. Oral imipramine treatment (100 to 600 mg, twice daily) led to frequent erection and masturbation while at rest in the stall in a nonsexual...

An 11 year old girl who was being treated for enuresis with imipramine developed acrocyanosis of the hands and feet. All biochemical and haematological investigations gave normal results. When imipramine was stopped the girl recovered within three days.

We examined the influence of chronic adrenocorticotropic hormone (ACTH) treatment on the number of Ki-67-positive cells in the dentate gyrus of the hippocampus in rats. ACTH treatment for 14 days decreased the number of such cells. The administration of imipramine or lithium alone for 14 days had no effect in saline-treated rats. The effect of ACTH was blocked by the administration of imipramin...
