Efficacy and Safety of Naloxegol in Patients with Chronic Non-Cancer Pain Who Experience Opioid-Induced Constipation: A Pooled Analysis of Two Global, Randomized Controlled Studies.

Objective: This study evaluates the onset, magnitude, and consistency of improvement of opioid-induced constipation (OIC) symptoms with naloxegol treatment.

Methods: This was a pooled analysis of two Phase 3, double-blind, randomized, placebo-controlled studies (KODIAC-04/05, NCT01309841/NCT01323790) in patients with chronic non-cancer pain and OIC treated with naloxegol 25mg or 12.5mg daily.

A method to assess the dissipation of the [corrected] residual effects of [corrected] hypnotics: eszopiclone versus zopiclone.

Next-day residual effects of single evening doses of 3 mg of eszopiclone, 7.5 mg of zopiclone, and placebo were assessed in a randomized, double-blind, placebo-controlled, 3-way crossover study that used a mild sleep restriction protocol (sleep duration, 7 hours). During each period, 91 healthy volunteers spent 2 consecutive nights in the laboratory with time in bed restricted to 7 hours.

Seasonal affective disorder and its prevention by anticipatory treatment with bupropion XL.

Background: Seasonal affective disorder (SAD) can cause significant distress and impairment. No antidepressant studies have previously attempted to prevent the onset of autumn-winter depression.

Methods: Three prospective, randomized, placebo-controlled prevention trials were conducted on 1042 SAD patients, enrolled in autumn and treated while still well, across the northern US and Canada.

Use of bupropion in combination with serotonin reuptake inhibitors.

Incomplete symptom remission and sexual side effects are common problems for which bupropion often is added to treatment with selective serotonin and serotonin-norepinephrine reuptake inhibitors (SSRIs and SNRIs) for patients with major depressive disorder (MDD). This article reviews the literature on combining bupropion with SSRIs or SNRIs. We used MEDLINE to select studies that included patients diagnosed with MDD treated with any combination of bupropion and an SSRI or SNRI, either to enhance antidepressant response or to ameliorate antidepressant-associated sexual dysfunction.

Remission rates following antidepressant therapy with bupropion or selective serotonin reuptake inhibitors: a meta-analysis of original data from 7 randomized controlled trials.

Background: Although it is widely believed that the various classes of antidepressants are equally effective, clinically meaningful differences may be obscured in individual studies because of a lack of statistical power. The present report describes a meta-analysis of original data from a complete set of studies comparing the norepinephrine/dopamine reuptake inhibitor (NDRI) bupropion with selective serotonin reuptake inhibitors (SSRIs; sertraline, fluoxetine, or paroxetine).

Method: Individual patient data were pooled from a complete set of 7 randomized, double-blind studies comparing bupropion (N = 732) with SSRIs (fluoxetine, N = 339; sertraline, N = 343; paroxetine, N = 49) in outpatients with major depressive disorder (DSM-III-R or DSM-IV); 4 studies included placebo (N = 512).

Does pretreatment insomnia or anxiety predict acute response to bupropion SR?

Background: This retrospective analysis was conducted to determine whether pretreatment levels of insomnia or anxiety were associated with likelihood of or time to antidepressant response with bupropion sustained release (SR).

Methods: Data from an open-label, 8-week, acute phase multicenter study of 797 adult outpatients with recurrent, nonpsychotic major depressive disorder who received bupropion SR (300 mg/day) were used. Depressive symptom severity was measured by the 17-item Hamilton Rating Scale for Depression (HAM-D17), insomnia by totaling the three HAM-D17 insomnia items (early, middle, late), and anxiety by the 14-item Hamilton Rating Scale forAnxiety.

A Review of the Neuropharmacology of Bupropion, a Dual Norepinephrine and Dopamine Reuptake Inhibitor.

BACKGROUND: The neurochemical and biological effects of antidepressant medications have become better defined over the last decade. When the anti-depressant bupropion was introduced in the United States in 1989, the specific pharmacologic basis of its clinical effects was uncertain. Research conducted over the past decade has significantly advanced the understanding of the neuropharmacology of bupropion and has demonstrated a novel mechanism of antidepressant activity.
