The brain binding kinetics and distribution of the antidepressant venlafaxine, labelled with 11C in the O-methyl position, was studied by PET after intravenous injection in anesthetized pigs. In addition, venlafaxine's action on serotonin (5-HT) uptake was studied in vitro in blood platelets obtain from humans or pigs.

The present study examines the effects of the antidepressant venlafaxine, a dual amine reuptake inhibitor, on (a) in vivo regulation of the densities of high- and low-affinity dihydroalprenolol (DHA) binding sites in the cortex of normal and reserpinized Sprague-Dawley rats and (b) targets beyond the beta adrenoceptor. While venlafaxine (30 mg/kg i.p. b.i.d.) administered for 4 d did not alter ...

Venlafaxine is a novel antidepressant with a rapid onset of action. It is highly efficacious in the treatment of depression and in comparison to the traditional thcyclic antidepressants, it has a favourable side effects profile. Although effective, venlafaxine too carries a risk for manic switch in bipolar affective disorder patients. Give the paucity of literature, we report a case of venlafax...

Venlafaxine, an atypical antidepressant drug, has been used to treat several neurological disorders, presenting excellent efficacy and tolerability. Clinical seizures after venlafaxine treatment have occasionally been reported when the drug was used at very high doses or in combination with other medications. The aim of the present study was to investigate the convulsant effects of venlafaxine ...

OBJECTIVE Patients with major depressive disorder (MDD) experience sleep disturbances that may be worsened by some antidepressant drugs early in treatment.

CONTEXT No large-scale posttraumatic stress disorder drug trials have been conducted to evaluate treatment effects beyond 12 weeks outside of those with selective serotonin reuptake inhibitors. OBJECTIVE To evaluate the efficacy of venlafaxine extended release (ER), a serotonin norepinephrine reuptake inhibitor, in posttraumatic stress disorder. DESIGN 6-month, double-blind, placebo-control...
