OBJECTIVE The purpose of this study was to compare the effectiveness and tolerability of tranylcypromine and combination treatment with extended-release venlafaxine and mirtazapine in patients with treatment-resistant major depression whose current depressive episode had not responded adequately to treatment in three prior prospective medication trials. METHOD Adult outpatients with nonpsycho...

We conducted a cost-effectiveness analysis of acute major depressive disorder (MDD) using serotonin-norepinephrine reuptake inhibitors (SNRIs; venlafaxine), selective serotonin reuptake inhibitors (SSRIs; fluoxetine, fluvoxamine, sertraline, paroxetine), or tricyclic antidepressants (TCAs; amitriptyline, imipramine, desipramine, nortriptyline). A decision-tree model over 6 months was constructe...

The objective of the study was to compare the efficacy and safety ofmilnacipran and Venlafaxine in major depressive disorder. The study was conducted in 120 patients suffering from major depressive disorder as per DSM-IV criteria. Patients were randomized to two groups and were given milnacipran (25, 50mg BD) and venlafaxine(75, 150mg OD) for 8 weeks. The primary efficacy parameter was the Hami...

BACKGROUND Chronic abuse of opiates induces dependency, but the neurobiological mechanisms of this event remain unclear. The aim of this study was to evaluate the effects of intracerebroventricular of venlafaxine on the morphine dependence and pain perception. METHODS A total of 80 adult male rats were divided into two major groups: (1) 40 of them was divided into groups of positive control (...

BACKGROUND Generalised anxiety disorder (GAD) is one of the commonest anxiety disorders and is treated almost entirely in primary care. Most recent studies performed in GAD have excluded depression for regulatory reasons. As GAD is usually a co-morbid disease, often co-existing with depression, the results from recent studies have only limited relevance to the naturalistic population. This stud...

The stereoselectivity of R,S-venlafaxine and its metabolites R,S-O-desmethylvenlafaxine, N-desmethylvenlafaxine, O,N-didesmethylvenlafaxine, N,N-didesmethylvenlafaxine and tridesmethylvenlafaxine was studied in three processes: (i) anaerobic and aerobic laboratory scale tests; (ii) six wastewater treatment plants (WWTPs) operating under different conditions; and (iii) a variety of wastewater tr...

Antidepressant therapy is considered as one of the factors leading to male infertility. In this study, the effects of long-term treatment with fluoxetine or venlafaxine were investigated on electrical field stimulation (EFS, 1-64 Hz), noradrenaline (10(-8) to 10(-4) M), serotonin (10(-8) to 10(-4) M), adenosine 5'-triphosphate [ATP (10(-8) to 10(-4) M)] and 80 mM KCl-induced contractile respons...

Neuropathic pain constitutes a serious therapeutic problem. In most cases polytherapy is necessary. Tramadol and antidepressants have common mechanisms of action and are frequently used together in clinical practice, thus interaction between them is very important. In the present study isobolographic analysis for equivalent doses of drugs was applied to examine the nature of interaction between...

Accessible online at: www.karger.com/journals/nef Venlafaxine, a 2-phenyl-2 (1-hydroxycycloalkyl) ethylamine derivate, is an inhibitor of both serotonin and norepinephrine re-uptake and was termed a ‘dual uptake inhibitor’ [1]. We report on a venlafaxine-treated patient who developed Fanconi’s syndrome (FS) and hyponatremia secondary to inappropriate antidiuretic hormone secretion syndrome (SIA...

Venlafaxine is a newly introduced antidepressant that is clinically different from other antidepressants, possesses a slightly different mechanism of action and may have unique efficacy properties and a faster onset of action. A case of venlafaxine induced severe hypertension is reported to highlight the need for caution while using this drug.
