While it is clear that males and females with eating disorders share more features in common than dissimilarities, males are distinctive in their past histories of obesity, sexual identity concerns, defensive dieting, and dieting in relationship to sports participation. All adolescents with an eating disorder are likely to be guarded in terms of disclosing items affecting their psychological state. Young men may be more so. In light of this fact, diagnosis of these disorders in adolescent male patients still depends on ruling out possible organic etiologies, thoroughly assessing the adolescent's mental status, and looking for underlying psychiatric symptoms. The association between mood disorders, namely depression, and obsessive-compulsive disorder as well as other anxiety disorders is as strong in young males with eating disorders as with females. Assessment of developmental and nutritional status is key to the diagnosis and is helpful in monitoring recovery. Standards of monitoring other than weight are important and have been outlined. Lastly, family psychodynamics must be addressed in order to provide the eating-disordered young man with more control as well as more independence in order that he take more personal responsibility for a healthier lifestyle.

In this paper, the author reviews the dosing strategy for each major class of antidepressant drugs. The long-accepted strategy of moving from low to high dosages may need to be revised when the newer serotonergic agents are used to treat depressed patients. Evidence indicates that these drugs may be both better tolerated and more effective at lower dosages. Several studies in support of this hypothesis are reviewed. Possible dosing strategies of serotonergic agents, such as fluoxetine, in the treatment of obsessive compulsive disorder, obesity, and other nondepressive disorders, are also discussed.

2-(3,4-Dichlorobenzyl)-2-dimethylamino-1-propanol, hydrochloride (JO 1017) is a novel antidepressant drug. Its biochemical and pharmacological properties were investigated in mice, rats, dogs, rabbits and guinea pigs. In vitro, it selectively inhibited serotonin uptake and had a high affinity for the 3H-paroxetine and 3H-imipramine binding sites. Biochemical studies demonstrated the lack of MAO-A and MAO-B inhibition and the absence of marked affinity for muscarinic, histaminic or other conventional brain receptors. Chronic treatment with JO 1017 induced a decrease in the Bmax values for imipramine sites but did not modify the Bmax for beta-adrenergic and 5-HT2 receptors. The neuropsychopharmacological profile of JO 1017 is characterized by a decrease of the immobility times in behavioural despair tests with mice, a decrease of the escape failures in the rat learned helplessness test, a strong potentiation of L-5-HT P-induced head-twitches in mice and an antagonism of reserpine-induced ptosis in rabbits. It weakly antagonized oxotremorine-induced hypothermia and did not influence the hypothermia induced by apomorphine. In contrast to most other antidepressants, a high dose of JO 1017 induced hypermotility in mice placed in an activity meter without producing stereotyped behaviour and group toxicity. Unlike tricyclic antidepressants, JO 1017 was devoid of severe cardiotoxicity in guinea pigs and had no central anticholinergic nor antihistaminic properties. These results suggest that JO 1017 is a selective serotonin uptake inhibitor with a high safety margin. JO 1017 may have a potential clinical utility both in the treatment of depression and for indications where serotonin transmission is involved, e.g., anxiety, panic attack, obsessive compulsive disorder, obesity and alcohol consumption.

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 (0.15%) than placebo-treated patients (0.65%) experienced events suggestive of aggression (hostility, personality disorder, antisocial reaction). A relative risk analysis indicated that aggression events were four times more likely to occur in placebo-treated patients than in fluoxetine-treated patients. Although the possibility that some rare phenomenon was not detected cannot be excluded, this meta-analysis did not show fluoxetine to be associated with an increased risk of emergence of violent or aggressive behaviour.

The introduction of selective serotonin reuptake inhibitors (SSRIs), which are, in general, safer and more easily tolerated than conventional antidepressants, has had a profound effect on the treatment of affective illnesses and obsessive-compulsive disorder (OCD). A number of symptoms associated with eating disorders overlap those of depression and OCD, suggesting a theoretical and practical case for evaluating the SSRIs in the treatment of anorexia nervosa, bulimia nervosa, binge-eating disorder, and obesity. Despite the expectations for SSRIs in the treatment of eating disorders, clinical investigations have yielded mixed results. In this paper, results from clinical studies of SSRIs (with and without concomitant psychotherapy) in the treatment of anorexia and bulimia nervosa, binge eating disorder, and obesity are reviewed, directions for future research are suggested, and practical recommendations for the clinician are provided.

The second and third generation of antidepressants, i.e., the selective serotonin reuptake inhibitors, nefazodone, venlafaxine, and mirtazapine, are proving to be useful in a variety of seemingly diverse disorders, including most anxiety disorders. In addition to receiving approval from the U.S. Food and Drug Administration (FDA) for major depressive disorder, some of the newer antidepressants have received FDA approval for other disorders, e.g., generalized anxiety disorder (venlafaxine), bulimia nervosa (fluoxetine), obsessive-compulsive disorder (fluvoxamine, paroxetine, sertraline, and fluoxetine), social phobia (paroxetine), panic disorder (sertraline, paroxetine), and posttraumatic stress disorder (sertraline). In controlled studies, these agents have also shown usefulness in premenstrual dysphoric disorder, borderline personality disorder, obesity, smoking cessation, and alcoholism. This article describes the new and potential indications for recently developed antidepressants and the studies that suggested these indications.

5-HT(2) family serotonin receptors, principal sites of action of serotonin in the brain, represent major molecular targets for drugs used in treating a variety of diseases including schizophrenia, depression, anxiety, eating disorders, obsessive-compulsive disorder, chronic pain conditions and obesity. The 5-HT(2) family of receptors has three members: 5-HT(2A), 5-HT(2B) and 5-HT(2C). Therefore, it is likely that subtype-selective compounds will be needed to avoid serious side effects and to enhance therapeutic indices. Unfortunately, recent insights into the structure and function of 5-HT(2A) receptors have revealed that structurally-diverse agonists and antagonists have distinct modes of interacting with 5-HT(2A) receptors, complicating efforts at structure-based drug-design. These distinct binding modes would not have been predicted based on conventional structure-activity relationships or static docking models. Fortunately, these complicated binding modes can be predicted and simulated using molecular dynamics, allowing for the possibility of structure-based drug design. Thus, provided appropriately sophisticated drug design strategies are employed, it is likely that uniquely valuable medications will result which could have great potential for treating a variety of mental and physical illnesses.

Biogenic amine transporters (BATs) are integral membrane proteins that translocate biogenic amine neurotransmitters [norepinephrine, dopamine (DA) and 5-hydroxytryptamine (5-HT)] across cell membranes. BATs are the principal sites of action for many psychotropic drugs, including abused stimulants such as cocaine and methamphetamine. Preclinical and human data demonstrate that withdrawal from long-term cocaine administration produces a dual deficit of synaptic DA and 5-HT in the brain, indicating the advantage of developing medications that normalize impairments in both neurotransmitter systems. In this article, we review data supporting the notion that stimulant effects normally produced by increased levels of extracellular DA can be antagonized by concurrent increases in levels of extracellular 5-HT. Accordingly, nonselective BAT substrates that can release both DA and 5-HT, such as the novel compound PAL287, have low abuse potential while maintaining the ability to suppress drug-seeking behavior. The collective findings indicate that such drugs will provide neurochemical normalization therapy for cocaine addiction and might also be useful for treating depression, obsessive-compulsive disorder, attention deficit disorder and obesity.

The 5-HT(2C) receptor subtype has been implicated in a wide variety of conditions including obesity, anxiety, depression, obsessive compulsive disorder, schizophrenia, migraine and erectile dysfunction and as a consequence has received considerable attention as a target for drug discovery. Here we review the pharmacological, pharmacokinetic and toxicological profile of WAY-163909 {(7bR,10aR)-1,2,3,4,8,9,10,10a-octahydro-7bH-cyclopenta-[b][1,4]diazepino[6,7,1hi]indole}, a novel 5-HT(2C) receptor selective agonist. Consistent with a potential therapeutic utility in obesity, schizophrenia and depression WAY-163909 was found to have robust dose-dependent effects in animal models of obesity, psychotic-like behavior or depression.

The aim of this study is to examine relationships of sleep duration with sociodemographic and health-related factors, psychiatric disorders and sleep disturbances in a nationwide sample in Korea. A total of 6510 subjects aged 18-64 years participated in this study. Logistic regression was used to calculate the odd ratios and 95% confidence intervals of the covariates, psychiatric disorders and sleep disturbances across the following sleep duration categories: 5 h or less, 6, 7, 8 and 9 h or more per day. Low levels of education, unemployment and physical illness were associated with sleeping for 5 h or less and 9 h or more. Being older and widowed/divorced/separated, high levels of physical activity, pain/discomfort, obesity and high scores on the General Health Questionnaires were associated with sleeping for 5 h or less. Female, being younger and underweight were associated with sleeping for 9 h or more. Alcohol dependence, anxiety disorder and social phobia were associated significantly with sleeping for 5 h or less and 9 h or more. Other psychiatric disorders were more common in subjects who slept for 5 h or less (e.g. alcohol use disorder, mood disorder, major depressive disorder, dysthymic disorder, obsessive-compulsive disorder and specific phobia) or 9 h or more (e.g. post-traumatic stress disorder). In addition, subjects who slept for 5 h or less reported more sleep disturbances than did subjects who slept for 7 h. Short or long sleep is associated with psychiatric disorders and/or sleep disturbance, therefore attention to the mental health of short or long sleepers is needed.
