In a European, multicenter, double-blind study, 244 adolescents, 13 to 18 years old, with major depression were randomized to treatment with citalopram (n = 124) or placebo (n = 120). One third of the patients in both groups withdrew from the study. No significant differences in improvement of scores from baseline to week 12 between citalopram and placebo were found. The response rate was 59% to 61% in both groups according to the Schedule for Affective Disorders and Schizophrenia for school-aged children-Present episode version (Kiddie-SADS-P) (depression and anhedonia scores < or =2) and Montgomery Asberg Depression Rating Scale (MADRS) (> or =50% reduction). Remission (MADRS score < or =12) was achieved by 51% of patients with citalopram and 53% with placebo. A post hoc analysis revealed that more than two thirds of all patients received psychotherapy during this study. For those patients not receiving psychotherapy, there was a higher percentage of Kiddie-SADS-P responders with citalopram (41%) versus placebo (25%) and a significantly higher percentage of MADRS responders and remitters with citalopram (52% and 45%, respectively) versus placebo (22% and 19%, respectively). Mild to moderate treatment-emergent adverse events were reported in 75% citalopram and 71% of placebo patients, most commonly headache, nausea, and insomnia. Serious adverse events occurred in 14% to 15% in both groups. Suicide attempts, including suicidal thoughts and tendencies, were reported by 5 patients in the placebo group and by 14 patients in the citalopram group (not significant) with no pattern with respect to duration of treatment, time of onset, or dosage. In contrast, the suicidal ideation (Kiddie-SADS-P) single item showed worsening more frequently in the placebo (18%) than in the citalopram group (8%).

Negative symptoms are considered the most debilitating and refractory aspect of schizophrenia, being associated with poor social, occupational and global outcomes. Conventional antipsychotics have limited efficacy against these symptoms and poor tolerability profiles. Atypical antipsychotics are an alternative treatment, and this 12-week, randomised, flexibly dosed study compared the efficacy, safety and tolerability of quetiapine and olanzapine in this regard. Of the 40 patients who entered the study (32 male; 8 female), 19 were randomised to quetiapine (mean dose 637 mg/day, mean treatment duration 80 days) and 21 to olanzapine (mean dose 16 mg/day, mean treatment duration 78 days). Quetiapine and olanzapine were similarly effective: in each treatment group significant improvements at Week 12 were observed for negative symptom scores on the SANS and the PANSS, and for subscale scores of affective flattening and alogia on the SANS. Both treatments were well tolerated in this patient population, with no worsening of extrapyramidal symptoms in either case. Anxiety and insomnia were the most common adverse events (> or =7% of patients in each group), but were not drug-related. Although this is a small study with limited power, the results support the effectiveness of quetiapine and olanzapine in treating the negative symptoms of schizophrenia.

Sleep is an active state that is critical for our physical, mental, and emotional well-being. Sleep is also important for optimal cognitive functioning, and sleep disruption results in functional impairment. Insomnia is the most common sleep disorder in psychiatry. At any given time, 50% of adults are affected with 1 or more sleep problems such as difficulty in falling or staying asleep, in staying awake, or in adhering to a consistent sleep/wake schedule. Narcolepsy affects as many individuals as does multiple sclerosis or Parkinson disease. Sleep problems are especially prevalent in schizophrenia, depression, and other mental illnesses, and every year, sleep disorders, sleep deprivation, and sleepiness add billions to the national health care bill in industrialized countries. Although psychiatrists often treat patients with insomnia secondary to depression, most patients discuss their insomnia with general care physicians, making it important to provide this group with clear guidelines for the diagnosis and management of insomnia. Once the specific medical, behavioral, or psychiatric causes of the sleep problem have been identified, appropriate treatment can be undertaken. Chronic insomnia has multiple causes arising from medical disorders, psychiatric disorders, primary sleep disorders, circadian rhythm disorders, social or therapeutic use of drugs, or maladaptive behaviors. The emerging concepts of sleep neurophysiology are consistent with the cholinergic-aminergic imbalance hypothesis of mood disorders, which proposes that depression is associated with an increased ratio of central cholinergic to aminergic neurotransmission. The characteristic sleep abnormalities of depression may reflect a relative predominance of cholinergic activity. Antidepressant medications presumably reduce rapid eye movement (REM) sleep either by their anticholinergic properties or by enhancing aminergic neurotransmission. Intense and prolonged dreams often accompany abrupt withdrawal from antidepressant drugs, a reflection of an REM rebound after drug-induced REM deprivation. The postulated link between sleep and psychiatric disorders has been reinforced by the findings of modern neurobiology.

Antipsychotic medications, specifically the atypical agents, serve as first-line treatment options for patients with psychotic disorders, including individuals with schizophrenia or schizoaffective disorder. Atypical antipsychotics are also often prescribed off-label as either the primary treatment or as an adjunctive treatment for individuals with other disorders, including mood disorders without psychosis, behavioral disorders, and insomnia. Despite the generally superior side-effect profiles of atypical antipsychotics compared with typical antipsychotic agents, the atypicals have been associated with a number of serious side effects, including metabolic disorders, cardiovascular disorders, seizures, hyperprolactinemia, and movement disorders. This article offers a stepwise approach to the management of antipsychotic side effects: Abstinence, Anticipation, Reduction, and Treatment (AART). The steps in AART are hierarchical, but often overlap in the areas of risk prevention and minimization. The authors discuss issues relevant to each level of intervention and provide suggestions for integrating the AART approach into a comprehensive treatment plan. By incorporating this stepwise approach into their clinical decision-making process, prescribers may be able to optimize the risk:benefit ratio associated with the prescription of atypical antipsychotics.

Subjects were patients with schizophrenia or schizoaffective disorder enrolled in extension studies (Study A and Study B) after participating in 12-week studies of long-acting injectable risperidone [Kane, J.M., Eerdekens, M., Lindenmayer, J.-P., Keith, S.J., Lesem, M., Karcher, K., 2003. Long-acting injectable risperidone: efficacy and safety of the first long-acting atypical antipsychotic. Am. J. Psychiatry 160, 1125-1132; Lindenmayer, J.-P., Eerdekens, L., Berry, S., Eerdekens, M., 2004. Safety and efficacy of long-acting risperidone in schizophrenia: a 12-week, multicenter, open-label study in stable patients switched from typical and atypical oral antipsychotics. J. Clin. Psychiatry 65, 1084-1089]. Twelve months of treatment were completed by 55% of Study A patients and 52% of Study B patients. The median modal dose of long-acting injectable risperidone was 50 mg/14 days in both studies. Most frequent adverse events were psychosis, headache, insomnia, agitation, and rhinitis. EPS-related adverse events were reported in 33% of patients in Study A and 22% in Study B. Patients with Clinical Global Impressions ratings of "not ill" and "mild" increased from 14% at baseline to 54% at endpoint in Study A and from 42% to 65% in Study B. It is concluded that treatment with long-acting injectable risperidone for 1 year or longer appeared to be safe and well tolerated in patients with schizophrenia or schizoaffective disorder.

Guidelines on the prescription of benzodiazepines recommend their use be limited to the short-term relief of severe anxiety or insomnia. However, clinical experience suggests that in psychiatry these drugs may be being prescribed more widely. The aim of this survey was to investigate benzodiazepine prescribing in a specialist UK psychiatric hospital using a structured interview with consultant psychiatrists. Prescribers were also asked their views on the UK CSM guidance on benzodiazepines (1988). Of 412 inpatients, 77 (18.7%) were receiving 90 benzodiazepine prescriptions for psychiatric indications. Most prescriptions were for anxiety (45/90; 50.0%), aggression (23/90; 25.6%) and agitation (13/90; 14.4%). Use was commonest for acquired brain injury, schizophrenia and personality disorders. Much usage was chronic (only 4/90 (4.4%) prescriptions had been initiated within the previous 4 weeks) and off-label (85/90; 94.4%). Prescribers were concerned about the addictive nature of benzodiazepines for these patients and to a lesser extent about their abuse potential. Most consultants believed the UK CSM guidance was too restrictive in relation to their clinical practice and needed modification to encompass new indications, for example rapid tranquillization, and specialist prescribing. In psychiatry benzodiazepines are quite frequently used in the management of a number of groups of difficult-to-treat patients. Although largely not evidence based, some psychiatrists report a favourable risk-benefit ratio for benzodiazepines in the treatment of certain patients.

In untreated schizophrenia, psychotic decompensation is associated with profound insomnia, one of the prodromal symptoms associated with psychotic relapse. First- and second-generation antipsychotic medication can ameliorate this insomnia, but side effects may include sedation or residual insomnia. Patients who are clinically stable and medicated may continue to experience disturbed sleep, including long sleep-onset latencies, poor sleep efficiency, slow wave sleep deficits, and short rapid eye movement latencies. Schizophrenia also can be associated with comorbid sleep disorders, which may be enhanced or induced by antipsychotic medication. Sleep disorders in schizophrenia should be treated vigorously because normalized sleep and its restorative processes may be essential for a positive clinical outcome.

Brain function is based on an exquisite balance between excitatory and inhibitory neurotransmission. GABAergic neurons provide the major inhibitory control. By controlling spike timing and sculpting neuronal rhythms they play a key role in regulating behavior. GABAergic neurons are highly diverse and operate with a corresponding diversity of GABAA receptor subtypes. In this article, the contribution of GABAA receptor deficits to central nervous system disorders, in particular anxiety disorders, epilepsy, schizophrenia and insomnia, is reviewed.

Bupropion was initially developed and licensed for the treatment of major depressive disorder in the United States in 1989. It was licensed as a pharmacotherapy for smoking cessation in the United States in 1997 and in the United Kingdom in 2000, and for the prevention of seasonal major depressive episodes in patients with seasonal affective disorder in the United States in 2006. Its main mechanism of action is believed to be via dopamine and noradrenalin reuptake inhibition. In addition to proven clinical efficacy for the treatment of major depression, the prevention of depressive episodes in patients with seasonal affective disorder, and as an aid to smoking cessation treatment, bupropion has demonstrated efficacy for attenuation of symptoms of attention deficit hyperactivity disorder, and more recently it has shown anti-inflammatory action against proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha), which may be implicated in a number of inflammatory diseases such as Crohn's disease. The twice-daily sustained-release formulation has been extensively evaluated for smoking cessation and has shown continuous smoking abstinence rates at one year of the order of 20% across many clinical groups including healthy smokers, and smokers with cardiovascular disease, chronic obstructive airways disease, depression and schizophrenia. Bupropion is well tolerated with side effects including insomnia, headache, dry mouth, dizziness and nausea. Bupropion is a cytochrome p450 2D6 inhibitor and care must be taken when coprescribing with drugs cleared by this enzyme and when coprescribing with drugs that lower seizure threshold. Despite the clinical effectiveness and cost-effectiveness of bupropion as an aid to smoking cessation, its uptake for this indication remains low when compared with nicotine replacement therapy.

This multicenter, uncontrolled, naturalistic study evaluated the effectiveness and tolerability of 6 months of treatment with ziprasidone in 1266 patients with a diagnosis of schizophrenia. The percentage of responders (at least 30% reduction in PANSS total score) in the primary analysis sample (n=1022) was 47.3% (95% CI 44.2-50.4) at the end of the study. Patients showed a significant and clinically relevant reduction in the PANSS total, positive, negative and general psychopathology subscales scores (effect size of 1.60, 1.83, 0.62 and 1.40 respectively). Overall, 453 (35.8%) patients withdrew from the study; 9.3% withdrew owing to adverse events. Ziprasidone doses greater than 120 mg/day were associated with a lower risk of discontinuation for any cause (OR 0.46, 95% CI 0.33-0.65) Ziprasidone was well tolerated. Most common side effects were: insomnia, somnolence and nervousness. The effectiveness and tolerability of ziprasidone in clinical practice are consistent to those previously shown in the more restricted and homogeneous populations of clinical trials.
