Sexual dysfunctions as side effects of antidepressant treatments are being reported more and more frequently: they are one of the main reasons of dropout from therapy. These side effects are reported in between 20% and 40% of cases. The aim of this study is to highlight, following the actual evidence from the field of psychopharmacology, how these side effects may not be directly related to the...

Antidepressant augmentation strategies are commonly employed to treat depressed patients who do not respond to antidepressant monotherapy. Neuroinflammatory mechanisms have been implicated in depression, and nonsteroidal anti-inflammatory drugs (NSAIDs) have been found effective in animal models of depression both in monotherapy and when used to augment antidepressant drugs. However, results wi...

In this research at the first 2-amino-3-(3,4-dihydroxyphenyl)-2-methyl-propanoic acid  drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η)...

The objective of present research work was to design and characterize the venlafaxine HCl-loaded sodium alginate-based mucoadhesive microcapsules by ionic gelation technique using HPMC K100M as mucoadhesive polymer. The Placket-Burman Design was applied for preliminary screening of the formulations and systematic optimization by using Box-Behnken Design. The prepared microcapsules were characte...

Human models of emotional processing suggest that the direct effect of successful antidepressant drug treatment may be to modify biases in the processing of emotional information. Negative biases in emotional processing are documented in depression, and single or short-term dosing with conventional antidepressant drugs reverses these biases in depressed patients prior to any subjective change i...

OBJECTIVE To evaluate antidepressant like effect of tramadol in mice. MATERIALS AND METHODS Tramadol was administered at three different doses (10,20 and 40 mg/kg, i.p) once daily for 7 days to Swiss albino mice of either sex. The immobility period of control and drug treated mice were recorded in tail suspension test (TST).The antidepressant effect of tramadol was compared to that of fluoxet...

Antidepressant discontinuation syndrome occurs in approximately 20 percent of patients after abrupt discontinuation of an antidepressant medication that was taken for at least six weeks. Typical symptoms of antidepressant discontinuation syndrome include flu-like symptoms, insomnia, nausea, imbalance, sensory disturbances, and hyperarousal. These symptoms usually are mild, last one to two weeks...

The expression of brain-derived neurotrophic factor (BDNF) mRNA and protein and its primary receptor, TrkB mRNA shows circadian oscillations in adult rats; however it has been unclear if juvenile rats also display a similar pattern in circadian oscillations. We determined the levels of BDNF and TrkB mRNA and of BDNF protein at four separate time points during a 24 hperiod in the hippocampus and...

A number of antidepressants have emerged in the U.S. market in the past two decades. Selective serotonin reuptake inhibitors have become the drugs of choice in the treatment of depression, and they are also effective in the treatment of obsessive-compulsive disorder, panic disorder, and social phobia. New indications for selective serotonin reuptake inhibitors include post-traumatic stress diso...

Antidepressant drugs activate the cAMP signal transduction pathway through a variety of monoamine neurotransmitter receptors. Recently, molecular studies have identified a role for cAMP response element-binding protein (CREB) in the mechanism of action of chronically administered antidepressant drugs. However, the function of CREB in the behavioral and endocrine responses to these drugs has not...
