BACKGROUND P2X4 receptor (P2X4R), a purinoceptor expressed in activated spinal microglia, plays a key role in the pathogenesis of neuropathic pain. Spinal nerve injury induces up-regulation of P2X4R on activated microglia in the spinal cord, and blockade of this receptor can reduce neuropathic pain. The present study was undertaken to determine whether paroxetine, an inhibitor of P2X4R, could a...

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) that is currently available on the market and is suspected of causing congenital malformations in babies born to mothers who take the drug during the first trimester of pregnancy. We utilized organismal performance assays (OPAs), a novel toxicity assessment method, to assess the safety of paroxetine during pregnancy in a rodent model...

3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") is increasingly used by young people for its euphoric and empathic effects. MDMA can be used in combination with other drugs such as selective serotonin reuptake inhibitors. A clinical trial was designed where subjects pretreated with paroxetine, one of the most potent inhibitors of both 5-hydroxytryptamine reuptake and CYP2D6 activity, were c...

BACKGROUND The present maintenance study investigated whether the reduction in hypochondriacal complaints after initial treatment with CBT or paroxetine sustained during a follow-up period and whether psychiatric severity at pretest predicted the course of hypochondriacal symptoms. METHOD A naturalistic follow-up period of 18 months after a 16-week RCT consisting of 33 patients initially allo...

INTRODUCTION An investigation of the proportion of patients who have experienced mania with antidepressant treatment and their characteristics would seem to be of clinical use. AIMS The purpose of this clinical study was to examine the predictors of induction of mania in depression patients as a result of paroxetine treatment. METHOD A retrospective cohort analysis was carried out among dep...

Paroxetine is commonly used as a selective serotonin reuptake inhibitor for the treatment of depression and other psychiatric disorders. However, the molecular mechanisms of the paroxetine effects have not yet been sufficiently clarified. Using Xenopus oocyte expression assays, we investigated the effects of paroxetine on G protein-activated inwardly rectifying K+ (GIRK) channels, which play an...

BACKGROUND Some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. Furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. Therefore, human Adipose-Derived Stem Cells (hAD-SCs) may be a suitable source for regenerative medical applications....

OBJECTIVE To assess the effects of a selective serotonin reuptake inhibitor on semen parameters. DESIGN Prospective study. SETTING Academic medical center. PATIENT(S) Thirty-five healthy male volunteers, 18-65 years old. INTERVENTION(S) Paroxetine administration for 5 weeks. MAIN OUTCOME MEASURE(S) Serum hormone levels, semen analyses, percent sperm DNA fragmentation, and questionnair...

BACKGROUND It is uncertain whether higher doses of selective serotonin reuptake inhibitors have greater efficacy in generalised anxiety disorder. AIMS To assess the efficacy of different doses of escitalopram in generalised anxiety disorder. METHOD Randomised, double-blind, placebo-controlled, fixed-dose, parallel-group, 12-week study, with 681 patients: placebo (n=139); escitalopram, 5 mg/...
