  • Meta-Analysis of the Dose-Response Relationship of SSRI in Obsessive
    Molecular Psychiatry (2010) 15, 850–855 & 2010 Macmillan Publishers Limited All rights reserved 1359-4184/10 www.nature.com/mp ORIGINAL ARTICLE Meta-analysis of the dose-response relationship of SSRI in obsessive-compulsive disorder MH Bloch1, J McGuire1, A Landeros-Weisenberger1, JF Leckman1 and C Pittenger2 1Yale Child Study Center, Yale University School of Medicine, New Haven, CT, USA and 2Department of Psychiatry, Yale University School of Medicine, New Haven, CT, USA We sought to determine differences in efficacy and tolerability between different doses of selective serotonin reuptake inhibitors in the treatment of obsessive-compulsive disorder (OCD) using meta-analysis. We identified 9 studies involving 2268 subjects that were randomized, double-blind placebo-controlled clinical trials that compared multiple, fixed- doses of selective serotonin reuptake inhibitors (SSRIs) to each other and to placebo in the treatment of adults with OCD. Change in Y-BOCS score, proportion of treatment responders, and dropouts (all-cause and due to side-effects) were determined for each included study. Weighted mean difference was used to examine mean change in Y-BOCS score. Pooled absolute risk difference was used to examine dichotomous outcomes. Meta-analysis was performed using a fixed effects model in RevMan 4.2.8. We found that compared with either low or medium doses, higher doses of SSRIs were associated with improved treatment efficacy, using either Y-BOCS score or proportion of treatment responders as an outcome. Dose of SSRIs was not associated with the number of all-cause dropouts. Higher doses of SSRIs were associated with significantly higher proportion of dropouts due to side-effects.

  • A Synbiotic Mixture Augmented the Efficacy of Doxepin, Venlafaxine
    A synbiotic mixture augmented the efficacy of doxepin, venlafaxine, and fluvoxamine in mice model of depression Azadeh Mesripour1, Andiya Meshkati1, Valiolah Hajhashemi2 1Department of Pharmacology and Toxicology, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. 2‐ Isfahan Pharmaceutical Sciences Research Center, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. ABSTRACT Objective: Currently available antidepressant drugs have notable downsides; in addition to their side effects and slow onset of action their moderate efficacy in some individuals, may influence compliance. Previous literature has shown that probiotics may have antidepressant effects. Introducing complementary medicineproof in order to augment the efficacy of therapeutic doses of antidepressant drugs seems to be very important. Therefore the effect of adding a synbiotic cocktail in drinking water was assessed in mice model of despair following administrating three antidepressant drugs belonging to different classes. Methods: The marble burring test (MBT), and forced swimming test (FST) were used as animal model of obsessive behavior and despair. The synbiotic cocktail was administered in mice drinking water (6.25×106 CFU) for 14 days and the tests were performed on the days 7 and 14 thirty minutes after injecting the lowest dose of doxepin (1 mg/kg), venlafaxine (15 mg/kg), and fluvoxamine (15 mg/kg). Results: After 7 days of the synbiotic ingestion immobility time decreased in FST for doxepin (92 sec ± 5.5) and venlafaxine (17.3 sec ± 2.5) compared to their control group (drinking water) but fluvoxamine could decrease immobility time after 14 days of ingesting the synbiotic (70 sec ± 7.5).

Previous literature has shown that probiotics may have antidepressant effects. Introducing complementary medicine in order to augment the efficacy of therapeutic doses of antidepressant drugs appears to be very important. Therefore, the effect of adding a synbiotic mixture to drinking water was assessed in a mouse model of depression following the administration of three antidepressant drugs belonging to different classes. Materials and Methods: The marble burying test (MBT) and forced swimming test (FST) were used as animal models of obsessive behavior and despair. The synbiotic mixture was administered to the mice’s drinking water (6.25x106 CFU) for 14 days and the tests were performed 30 min after the injection of the lowest dose of doxepin (1 mg/kg), venlafaxine (15 mg/kg), and fluvoxamine (15 mg/kg) on days 7 and 14. Results: After 7 days of ingestion of the synbiotic mixture, immobility time decreased in the FST for doxepin (92±5.5 s) and venlafaxine (17.3±2.5 s) compared to the control group (drinking water), but fluvoxamine decreased immobility time after 14 days of ingestion of the synbiotic mixture (70±7.5 s).

  • Impact of Citalopram and Fluvoxamine on Platelet Response To
    S24_5 Impact of Citalopram and Fluvoxamine on Platelet Response to Clopidogrel, a Randomized, Double-blind, Crossover Trial Bruria Hirsh Racch1, Galia Spectre2, Ella Shai2, Amit Ritter3, David Varon2, Ronny Alcalai3 1School of Pharmacy, Hadassah Hebrew University Medical Center, Israel 2Coagulation Unit, Hematology, Hadassah Hebrew University Medical Center, Israel 3Heart Institute, Hadassah Hebrew University Medical Center, Israel Background: Selective serotonin reuptake inhibitors (SSRI) are widely used antidepressant agents. Studies have shown that use of SSRI in combination with aspirin or warfarin is associated with an increased risk bleeding, while little information is known about the interaction of SSRIs and clopidogrel. Fluvoxamine and citalopram are both SSRIs and while fluvoxamine is an inhibitor of CYP2C19 and thus might reduce the efficacy of clopidogrel, the effect of citalopram on liver metabolism is unknown. Aim: The aim was to assess the effect these two different SSRIs on platelet aggregation and on the laboratory response to clopidogrel. Methods: A randomized, double-blind, crossover study in 15 healthy volunteers comparing the antiplatelet effect of clopidogrel with and without fluvoxamine or citalopram .The response to clopidogrel was assessed by Light Transmittance Aggregometry with10µmol/L ADP and by vasodilator-stimulated phosphoprotein (VASP) phosphorylation, a measure of P2Y12 receptor reactivity. Results: Mean baseline platelet aggregation was 80.1%±3.4 and reduced to 23.5% after treatment with clopidogrel. Both fluvoxamine and citalopram had modest effect on platelet reactivity (65.8%±6.4, p=0.06 vs. baseline and 67.3%±6.3, p=0.07 vs. baseline respectively). Laboratory response to clopidogrel was significantly better in the presence of citalopram as compared to fluvoxamine both in aggregometry (23.4%±3 vs.

  • Luvox and Luvox CR (Fluvoxamine)
    23 Luvox and Luvox CR (fluvoxamine) Generic name: Fluvoxamine Available strengths: 25 mg, 50 mg, 100 mg tablets; 100 mg, 150 mg sustained-release capsules (Luvox CR) Available in generic: Yes Drug class: Selective serotonin reuptake inhibitor antidepressant General Information Luvox (fluvoxamine) was approved by the U.S. Food and Drug Administration (FDA) for the treatment of obsessive-compulsive disorder (OCD) and social aniety disorder, but not depression. The use of a medication for its approved indications is called its labeled use. In clinical practice, however, physicians often prescribe medications for unlabeled (“off-label”) uses when published clinical studies, case reports, or their own clinical experiences support the efficacy and safety of those treatments. Physicians may use Luvox for treatment of major depression, panic disorder, posttraumatic stress disorder, premenstrual dysphoric disorder, nocturnal enuresis (incontinence of urine) in children, and bulimia nervosa. Luvox is a serotonin-specific medication that works by blocking the reuptake of the neurotransmitter se- rotonin back into brain cells, thereby increasing its levels in the brain. OCD, depression, and other mental disorders may be caused by abnormally low levels of serotonin. This abnormality may in turn produce changes in affected areas of the brain, resulting in psychiatric symptoms such as depression or anxiety. The presumed action of Luvox and other selective serotonin reuptake inhibitors (SSRIs) is to increase serotonin levels, which may help to restore those areas of the brain to normal functioning. OCD may also be successfully treated with other SSRIs as well as the tricyclic antidepressant (TCA) Anafranil (clomipramine). Dosing Information The recommended starting dose of Luvox is 50 mg as a single bedtime dose.
