Abstract
Whereas monoamine oxidase (MAO) type B inhibitors are used as adjunct to L-3,4-dihydroxyphenylalanine (L-DOPA) in the treatment of Parkinson's disease (PD), the enzyme MAO type A (MAO-A) also participates in the metabolism of dopamine in the human and primate striatum. Here, we sought to assess the effect of the selective reversible MAO-A inhibitor moclobemide on L-DOPA anti-parkinsonian in the gold standard animal model of PD, the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-lesioned primate. We also assessed the effect of moclobemide on L-DOPA-induced dyskinesia and psychosis-like behaviours (PLBs). Experiments were performed in six MPTP-lesioned marmosets chronically treated with L-DOPA and exhibiting stable dyskinesia and PLBs upon each administration. In a randomised within-subject design, animals were administered a therapeutic dose of L-DOPA in combination with moclobemide (0.1, 1 and 10 mg/kg) or its vehicle, after which the severity of parkinsonism, dyskinesia, and PLBs was rated by an experienced blinded rater. Moclobemide significantly reduced the global parkinsonian disability (- 36% with 0.1 mg/kg, P < 0.05; - 38% with 1 mg/kg, P < 0.01; - 47% with 10 mg/kg, P < 0.01), when compared with its vehicle. This reduction of parkinsonism was not accompanied by an exacerbation of dyskinesia or PLBs. Reversible MAO-A inhibition with moclobemide appears as an effective way to increase the anti-parkinsonian action of L-DOPA, without negatively affecting dyskinesia or dopaminergic psychosis.

Abstract
Zusammenfassung. Diese Empfehlungen sollen dazu dienen, Fachpersonen das Wissen über die aktuelle Evidenz von Diagnostik und Therapie der Depression im Alter zur Verfügung zu stellen und damit zur frühzeitigen Erkennung und evidenzbasierten Behandlung beizutragen. Da für einige Behandlungsansätze nur rudimentär kontrollierte Studien vorliegen, wird auch das klinische Expertenwissen in die Beurteilung einbezogen. Im diagnostischen Vorgehen wird die besondere Symptomatik der Depression im Alter beleuchtet, auf die Suizidalität eingegangen und werden die häufig vorkommenden somatischen Komorbiditäten hervorgehoben. Auch Hypothesen zur Pathogenese, wie Neuroendokrinologie, Neurodegeneration und vaskuläre Faktoren, werden erläutert. In der Behandlung gilt heute ein integrierter biopsychosozialer Ansatz mit gezielten psychosozialen Interventionen, spezifischer Psychotherapie und einer antidepressiven Pharmakotherapie bei schweren Depressionen als sinnvoll. Daneben kommen auch chronobiologische oder Neurostimulationsverfahren zum Einsatz.

General and comparative efficacy and effectiveness of antidepressants in the acute treatment of depressive disorders: a report by the WPA section of pharmacopsychiatry.

Abstract
Current gold standard approaches to the treatment of depression include pharmacotherapeutic and psychotherapeutic interventions with social support. Due to current controversies concerning the efficacy of antidepressants in randomized controlled trials, the generalizability of study findings to wider clinical practice and the increasing importance of socioeconomic considerations, it seems timely to address the uncertainty of concerned patients and relatives, and their treating psychiatrists and general practitioners. We therefore discuss both the efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders. We explain and clarify useful measures for assessing clinically meaningful antidepressant treatment effects and the types of studies that are useful for addressing uncertainties. This includes considerations of methodological issues in randomized controlled studies, meta-analyses, and effectiveness studies. Furthermore, we summarize the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties, and differences between studies using antidepressants and/or psychotherapy. We also address the differential effectiveness of antidepressant drugs with differing modes of action and in varying subtypes of depressive disorder. After highlighting the clinical usefulness of treatment algorithms and the divergent biological, psychological, and clinical efforts to predict the effectiveness of antidepressant treatments, we conclude that the spectrum of different antidepressant treatments has broadened over the last few decades. The efficacy and clinical effectiveness of antidepressants is statistically significant, clinically relevant, and proven repeatedly. Further optimization of treatment can be helped by clearly structured treatment algorithms and the implementation of psychotherapeutic interventions. Modern individualized antidepressant treatment is in most cases a well-tolerated and efficacious approach to minimize the negative impact of otherwise potentially devastating and life-threatening outcomes in depressive disorders.

Abstract
Late-life depression is a rather difficult and complicated issue. Although there have been significant advances in our knowledge in this area, a large number of questions still remain unanswered. The aim of this review is a critical presentation of the current evidence for treatment of depression in the elderly. We summarize the evidence for the effectiveness and safety of a range of proposed treatments, including pharmacological, psychological and alternative therapies and lifestyle changes. The treatments with best evidence of effectiveness are antidepressant pharmacotherapy, electroconvulsive therapy, cognitive–behavioral therapy, psychodynamic psychotherapy, reminiscence therapy, problem-solving therapy and exercise. Implications for future research are discussed.

Abstract
Major Depressive Disorder is particularly frequent among physically ill inpatients. Despite the considerable human burden and financial costs, Major Depressive Disorder remains under-detected and under-treated. To improve this situation, clinical practice guidelines for the management of Major Depressive Disorder were developed for patients in the general hospital. They were adapted from existing good quality guidelines. A literature search has been conducted to identify guidelines and systematic reviews about the management of Major Depressive Disorder. The quality of the existing guidelines was evaluated by means of the AGREE instrument (Appraisal of Guidelines for Research and Evaluation). Complementary literature searches were necessary to answer questions such as "depression and physical illness" or "antidepressants and somatic medication". The guidelines were discussed by a multidisciplinary internal panel. The final version was reviewed by an external panel. This paper presents the development process and a summary of these guidelines for the management of Major Depressive Disorder. The adaptation of good quality guidelines to local needs requires much time, effort and skills. Easier ways for the adaptation and use of high quality guidelines at the local level may result from better coordination, organization and updating of guidelines at a national or supranational level.

Abstract
Moclobemide is a reversible inhibitor of monoamine-oxidase-A (RIMA) and has been extensively evaluated in the treatment of a wide spectrum of depressive disorders and less extensively studied in anxiety disorders. Nearly all meta-analyses and most comparative studies indicated that in the acute management of depression this drug is more efficacious than placebo and as efficacious as tricyclic (or some heterocyclic) antidepressants or selective serotonin reuptake inhibitors (SSRIs). There is a growing evidence that moclobemide is not inferior to other antidepressants in the treatment of subtypes of depression, such as dysthymia, endogenous (unipolar and bipolar), reactive, atypical, agitated, and retarded depression as with other antidepressants limited evidence suggests that moclobemide has consistent long-term efficacy. However, more controlled studies addressing this issue are needed. For patients with bipolar depression the risk of developing mania seems to be not higher with moclobemide than with other antidepressants. The effective therapeutic dose range for moclobemide in most acute phase trials was 300 to 600 mg, divided in 2 to 3 doses. While one controlled trial and one long-term open-label study found moclobemide to be efficacious in social phobia, three controlled trials subsequently revealed either no effect or less robust effects with the tendency of higher doses (600 - 900 mg/d) to be more efficacious. Two comparative trials demonstrated moclobemide to be as efficacious as fluoxetine or clomipramine in patients suffering from panic disorder. Placebo-controlled trials in this indication are, however, still lacking. A relationship between the plasma concentration of moclobemide and its therapeutic efficacy is not apparent but a positive correlation with adverse events has been found. Dizziness, nausea and insomnia occurred more frequently on moclobemide than on placebo. Due to negligible anticholinergic and antihistaminic actions, moclobemide has been better tolerated than tri- or heterocyclic antidepressants. Gastrointestinal side effects and, especially, sexual dysfunction were much less frequent with moclobemide than with SSRIs. Unlike irreversible MAO-inhibitors, moclobemide has a negligible propensity to induce hypertensive crisis after ingestion of tyramine-rich food ("cheese-reaction"). Therefore, dietary restrictions are not as strict. However, with moclobemide doses above 900 mg/d the risk of interaction with ingested tyramine might become clinically relevant. After multiple dosing the oral bioavailability of moclobemide reaches almost 100%. At therapeutic doses, moclobemide lacks significant negative effects on psychomotor performance, cognitive function or cardiovascular system. Due to the relative freedom from these side effects, moclobemide is particularly attractive in the treatment of elderly patients. Moclobemide is a substrate of CYP2C19. Although it acts as an inhibitor of CYP1A2, CYP2C19, and CYP2D6, relatively few clinically important drug interactions involving moclobemide have been reported. It is relatively safe even in overdose. The drug has a short plasma elimination half-life that allows switching to an alternative agent within 24 h. Since it is well tolerated, therapeutic doses can often be reached rapidly upon onset of treatment. Steady-state plasma levels are reached approximately at one week following dose adjustment. Patients with renal dysfunction require no dose reduction in contrast to patients with severe hepatic impairment. Cases of refractory depression might improve with a combination of moclobemide with other antidepressants, such as clomipramine or a SSRI. Since this combination has rarely been associated with a potentially lethal serotonin syndrome, it requires lower entry doses, a slower dose titration and a more careful monitoring of patients. Combination therapy with moclobemide and other serotonergic agents, or opioids, should be undertaken with caution, although no serious adverse events have been published with therapeutic doses of moclobemide to date. On the basis of animal data the combined use of moclobemide with pethidine or dextropropoxyphene should be avoided. There is no evidence that moclobemide would increase body weight or produce seizures. Some preclinical data suggest that moclobemide may have anticonvulsant property.

Abstract
A computer-based literature search of all antidepressant and electroconvulsive therapy (ECT) treatment studies published between 1995 and September 2001 was conducted. In addition, a review of published chapters, review articles, and metaanalyses was also conducted. Articles were categorized into those reporting comparative studies, those in which the therapeutic agent was not compared with another, articles about ECT, and review articles. These recent publications support the conclusions from prior reviews that antidepressants and ECT are effective and safe treatments for depressed elderly patients. Differences in efficacy and side effects appear to be slight among the various types of antidepressants. Research studies of depressed elderly increased markedly since 1995 compared with all previous years although more studies are still necessary.

Abstract
Antidepressivos são eficazes no tratamento da depressão em idosos. O sucesso do tratamento depende do tipo e da gravidade da depressão; das comorbidades com outras doenças psiquiátricas ou clínicas; da escolha adequada de antidepressivos, de sua eficácia e perfil de efeitos adversos; da orientação do paciente e de sua aderência ao tratamento. O manejo dos efeitos adversos em pacientes idosos, que usam muito mais medicações e apresentam mais doenças, é o ponto forte na escolha de antidepressivos. Em geral, os inibidores seletivos da recaptação de serotonina têm sido preferidos por apresentar menos riscos de complicações por efeitos adversos. Porém, diferentes antidepressivos podem ser preferíveis para diferentes pacientes. É indispensável que o médico conheça o paciente que irá tratar e o perfil de efeitos adversos e de possíveis interações medicamentosas dos antidepressivos para poder escolher o mais adequado para cada paciente. Neste artigo, são abordados os diferentes grupos de antidepressivos no tratamento agudo da depressão em idosos e o tratamento em populações especiais de idosos (idosos debilitados e idosos com demência).

Abstract
The newer antidepressants are as efficacious as the older agents in the treatment of depression. They have a side effect profile that is different from the older drugs and are generally better tolerated. Drug-drug interactions do exist with some of these agents and can usually be predicted from knowledge of their metabolism. When taken in overdose as the sole agents they are rarely fatal; seizures, nausea, vomiting, decreased level of consciousness, and tachycardia are common. In combination with other drugs, toxicity can be more severe. The serotonin syndrome can occur with many of these drugs, and the emergency physician must be vigilant in the evaluation of the overdose patient. CAs and older MAOIs are still in use and remain dangerous when taken in overdose. Patients asymptomatic after a period of observation in the ED usually can be discharged after psychiatric evaluation, when it is required.
