UNLABELLED Improvements in placebo groups of antidepressant trials account for a major part of the expected drug effects. We aimed to determine overall effect sizes of placebo and drug effects in antidepressant trials, and to analyze whether the placebo effect in antidepressant trials also occurs for patient self-perception, general psychopathology, and quality of life. METHODS Search terms c...

INTRODUCTION Celastrus paniculatus seed oil, commonly known as Malkangni or Jyotishmati, was in use from time immemorial to treat brain related disorders. Celastrus paniculatus seed oil has significant antidepressant-like activity in chronic unpredictable stressed mice. The present study was undertaken to evaluate the antidepressant-like effect of Celastrus paniculatus seed oil in unstressed mi...

Alprazolam differs from other benzodiazepines by the incorporation of a triazolo ring in the basic chemical structure. Several lines of evidence have supported that alprazolam and standard antidepressants have some similar actions, such as beta-adrenergic receptor down-regulation, antipanic effect. Because of the difference in opinions pertaining to the antidepressant effect of alprazolam, this...

Purpose. Depression and antidepressant use may independently increase the risk of acute myocardial infarction and mortality in adults. However, no studies have looked at the effect of depression on a broader thrombotic event outcome, assessed antidepressant use, or evaluated elderly adults. Methods. A cohort of 7,051 community-dwelling elderly beneficiaries who experienced a thrombotic cardiova...

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...

The antidepressant-like activity of magnesium, the non-specific N-methyl-D-aspartate glutamate receptor antagonist, in the mice forced swim test was demonstrated previously. In the present study, the effects of this biometal were studied in the rat forced swim test. Magnesium (MgCl2) at doses ranging from 15 to 50 mg Mg/kg reduced the immobility time in the forced swim test, thus exerting antid...

Antidepressant-like effects of metabotropic glutamate (mGlu)5 receptor antagonists have been reported previously. We now provide definitive identification of mGlu5 receptors as a target for these effects through the combined use of selective antagonists and mice with targeted deletion of the mGlu5 protein. In these experiments, the mGlu5 receptor antagonists 2-methyl-6-(phenylethynyl)-pyridine ...
