Olanzapine is a potential new "atypical" antipsychotic agent. The double-blind acute phase of this study compared three dosage ranges of olanzapine (5 +/- 2.5 mg/day [Olz-L], 10 +/- 2.

The study was designed to evaluate the pharmacokinetics of fluoxetine during repeated administration and to acquire preliminary data regarding the effectiveness of this antidepressant in a population undergoing hemodialysis. Six patients in each group completed the study.

The primary objective of this article is to review information pertinent to and emphasize the seriousness of a potential adverse monoamine oxidase inhibitor (MAOI)-serotonin uptake inhibitor interaction by considering, within the context of preclinical data, clinical cases in which an MAOI and fluoxetine hydrochloride, a specific serotonin uptake inhibitor, were administered in close temporal proximity. Clinical cases were identified by a review of spontaneous adverse event reports submitted voluntarily to Eli Lilly and Company through its drug surveillance program and by a review of reports of MAOI interactions published in the scientific literature. A discussion of eight selected clinical cases of acute adverse reactions (seven with fatal outcomes; one with a favorable response after cyproheptadine therapy) reported to Eli Lilly and Company in which an MAOI was initiated concurrently or shortly after the discontinuation of fluoxetine and a review of preclinical data suggest a possible role of serotonin and/or serotonin-dopamine interactions in the hypermetabolic state that may occur when a serotonin uptake inhibitor and an MAOI are coadministered, although alternative etiologic processes are possible as well.

Fluoxetine and imipramine were compared in a six-week, double-blind, randomized trial in 118 men and women, ages 18 to 70 years, hospitalized for major depressive disorder. Treatment groups were comparable at baseline. Median maintenance doses were: fluoxetine, 80 mg/day; imipramine, 200 mg/day.

A comprehensive meta-analysis was performed to address the possible association of fluoxetine with violence or aggression. Data from the United States Investigational New Drug Clinical Trial Databases for approved and potential indications (depression, obesity, bulimia nervosa, obsessive-compulsive disorder, smoking cessation, alcoholism; n = 3992) were evaluated. Statistically significantly fewer fluoxetine-treated patients (0.

To assess the rates and temporal patterns of activation and sedation as well as dose-effect relationships, adverse event data were evaluated from a fixed-dose study comparing placebo and fluoxetine, 5, 20 and 40 mg/day, in the treatment of major depressive disorder (n = 363) and the pooled data from two fixed-dose studies comparing placebo and fluoxetine, 20, 40 and 60 mg/day, in the treatment of major depressive disorder (n = 746). The adverse events 'nervousness', 'anxiety', 'agitation' and 'insomnia' were considered indicative of activation; 'somnolence' and 'asthenia' were considered indicative of sedation.

This paper reviews the effect of these diseases and their associated physiological derangements on the pharmacokinetics of fluoxetine and norfluoxetine. Metabolic studies of fluoxetine in man show that more than 70% of the radiolabelled compound is excreted in the urine.

Fluoxetine, a serotonin uptake inhibitor, and amitriptyline, a tricyclic antidepressant, were compared in a 5-week, multicenter, double-blind, randomized trial in 136 out-patient men and women, aged 21-70 years, with major depressive disorder. Overall efficacy was comparable with fluoxetine and amitriptyline [Hamilton 21-Item Rating Scale for Depression (HAM-D21), Raskin, Covi, Clinical Global Impressions-Severity and -Improvement, Patient's Global Impressions]. Mean +/- standard deviation decreases in HAM-D21 total score were 12.

Serotonin uptake inhibitors are generally considered activating antidepressants. To assess rates and temporal patterns of activation and sedation as well as dose-effect relationships, adverse event data were evaluated from a fixed-dose study comparing placebo and fluoxetine 5, 20, and 40 mg/day in the treatment of major depressive disorder (N = 363) and two fixed-dose studies pooled together comparing placebo and fluoxetine 20, 40, and 60 mg/day in the treatment of major depressive disorder (N = 746). The adverse events nervousness, anxiety, agitation, and insomnia were considered indicative of activation; somnolence and asthenia were considered indicative of sedation.

Downregulation of serotonin 5-HT1 receptors is the most frequently reported central nervous system neural effect of subchronic exposure to fluoxetine in rodents. However, downregulation of these receptors has not been universally demonstrated. Effects of subchronic exposure on 5-HT2 receptors are mixed.

The incidence and temporal patterns of activation and sedation were also assessed.
Method: Men and women who met DSM-III criteria for nonpsychotic major depressive episode (but with a current episode greater than or equal to 4 weeks) and had a 21-item Hamilton Rating Scale for Depression (HAM-D21) score greater than 20 were selected.
The effects of high-dose fluoxetine (median 80 mg/day), standard-dose imipramine (median 200 mg/day), and placebo were studied in 706 outpatients meeting DSM-III criteria for major depressive disorder. Baseline psychomotor activity of each patient was prospectively categorized as agitated, retarded, or neither. Rates of occurrence of total and significant (leading to discontinuation) activating adverse events (insomnia, agitation, anxiety, nervousness) and sedating events (somnolence, asthenia) were compared between treatments on an overall basis and within categories of baseline psychomotor activity.
