Bupropion for major depressive disorder: Pharmacokinetic and formulation considerations.

Background: Major depressive disorder (MDD) is a common psychiatric condition, with 6.6% of the adult population in the United States experiencing a major depressive episode during any given year. Depressed patients must receive adequate treatment to maximize the likelihood of clinical success.

15 years of clinical experience with bupropion HCl: from bupropion to bupropion SR to bupropion XL.

Background: Bupropion has been available in the United States since 1989. Initially a thrice-daily immediate-release formulation, a twice-daily sustained-release formulation followed in 1996, and, in August 2003, a once-daily extended-release formulation was introduced. On the 15th anniversary of its introduction, we undertook a review of the background/history, mechanism of action, formulations, and clinical profile of bupropion.

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.

Prevalence of sexual dysfunction among newer antidepressants.

Background: Sexual dysfunction commonly occurs during antidepressant treatment. However, the reported rates of sexual dysfunction vary across antidepressants and are typically underreported in product literature. The objectives of this study were (1) to estimate the prevalence of sexual dysfunction among patients taking newer antidepressants (bupropion immediate release [IR], bupropion sustained release [SR], citalopram, fluoxetine, mirtazapine, nefazodone, paroxetine, sertraline, venlafaxine, and venlafaxine extended release [XR]) and (2) to compare physician-perceived with patient-reported prevalence rates of antidepressant-associated sexual dysfunction.
