A randomized trial of a specific adherence enhancement program in sertraline-treated adults with major depressive disorder in a primary care setting.

Adherence to drug therapy is a limitation in treatment success for major depressive disorder (MDD). The influence of RHYTHMS, an information and ongoing interactive program designed by Pfizer Pharmaceuticals, to address patient adherence to sertraline therapy was evaluated in a primary care setting using a randomized, double-blind, parallel group controlled trial over 29 weeks. Remission was the primary outcome evaluated.

Sertraline and fluoxetine treatment of obsessive-compulsive disorder: results of a double-blind, 6-month treatment study.

The purpose of this study was to evaluate the comparative efficacy and tolerability of sertraline and fluoxetine in the treatment of obsessive-compulsive disorder (OCD). Outpatients meeting DSM-IV criteria for OCD, with a Yale-Brown Obsessive-Compulsive (Y-BOCS) total score >or= 17, an NIMH Global Obsessive-Compulsive (NIMH-OC) scale score >or= 7, and a CGI-Severity score >or= 4 were randomized to 24 weeks of double-blind treatment with sertraline (N = 77) or fluoxetine (N = 73). Primary efficacy measures consisted of the Y-BOCS, the NIMH-OC scale, and the CGI-Severity (CGI-S) and Improvement (CGI-I) scales.

Sertraline treatment of generalized social phobia: a 20-week, double-blind, placebo-controlled study.

Objective: The authors evaluated the efficacy, safety, and tolerability of sertraline, a selective serotonin reuptake inhibitor, in the treatment of generalized social phobia.

Method: Adult outpatients with generalized social phobia (N=204) from 10 Canadian centers were randomly assigned to receive sertraline or placebo in a 2:1 ratio for a 20-week double-blind study following a 1-week, single-blind, placebo run-in. The initial dose of sertraline was 50 mg/day with increases of 50 mg/day every 3 weeks permitted after the fourth week of treatment (dosing was flexible up to a maximum of 200 mg/day).

Prevention of relapse in generalized social phobia: results of a 24-week study in responders to 20 weeks of sertraline treatment.

The aim of this study was to evaluate the efficacy, tolerability, and effects on quality of life of sertraline, a selective serotonin reuptake inhibitor, in the prevention of relapse of generalized social phobia. Fifty adult outpatients with generalized social phobia who were rated much or very much improved on the Clinical Global Impression Scale of Improvement (CGI-I) after 20 weeks of sertraline treatment (50-200 mg/day) were randomly assigned in a one-to-one ratio to either continue double-blind treatment with sertraline or immediately switch to placebo for another 24 weeks. The initial 20-week study was placebo-controlled, and 15 responders to placebo also continued to receive double-blind placebo treatment in the continuation study.

Partial agonistic activity of R- and S-enantiomers of 8-OH-DPAT at 5-HT1A receptors.

In this study, the 5-HT1A agonistic activity of R- and S-enantiomers of the prototypical 5-HT1A agonist 8-OH-DPAT was investigated using in vivo microiontophoresis and the hypothermic response in rats. Both the R- and S-enantiomers suppressed current-dependently the firing activity of dorsal hippocampus CA3 pyramidal neurons. The number of spikes suppressed/nA of R-(+)-OH-DPAT was about 2-fold greater than that of S-(-)-OH-DPAT, which indicates greater agonistic activity of the R-enantiomer.
