Abstract
Behavioural and psychological symptoms of dementia (BPSD) are a clinical challenge for the lack of a sound taxonomy, frequent presentation with comorbid BPSD, lack of specific pharmacologic interventions, poor base of methodologically sound evidence with randomized clinical trials, contamination from the treatment of behavioural disturbances of young and adult psychiatric conditions, and small efficacy window of psychotropic drugs. We present here a treatment workflow based on a concept-driven literature review based on the notions that (i) the aetiology of BPSD can be mainly neurobiological (so-called 'primary' symptoms) or mainly environmental and functional ('secondary' symptoms) and that this drives treatment; (ii) the clinical efficacy of psychotropic drugs is driven by their specific profile of receptor affinity; (iii) drug treatment should follow the rules of 'start low-go slow, prescribe and revise'. This article argues in support of the distinction between primary and secondary BPSD, as well as their characteristics, which until now have been just sketchily described in the literature. It also offers comprehensive and pragmatic clinician-oriented recommendations for the treatment of BPSD.

Abstract
QUESTION Tricyclic antidepressants are used to treat depression worldwide, but the adverse effects have not been systematically assessed. Our objective was to assess the beneficial and harmful effects of all tricyclic antidepressants for adults with major depressive disorder. STUDY SELECTION AND ANALYSIS We conducted a systematic review with meta-analysis and trial sequential analysis. We searched CENTRAL, MEDLINE, Embase, LILACS and other sources from inception to January 2023 for randomised clinical trials comparing tricyclic antidepressants versus placebo or 'active placebo' for adults with major depressive disorder. The primary outcomes were depressive symptoms measured on the 17-item Hamilton Depression Rating Scale (HDRS-17), serious adverse events and quality of life. The minimal important difference was defined as three points on the HDRS-17. FINDINGS We included 103 trials randomising 10 590 participants. All results were at high risk of bias, and the certainty of the evidence was very low or low. All trials only assessed outcomes at the end of the treatment period at a maximum of 12 weeks after randomisation. Meta-analysis and trial sequential analysis showed evidence of a beneficial effect of tricyclic antidepressants compared with placebo (mean difference -3.77 HDRS-17 points; 95% CI -5.91 to -1.63; 17 trials). Meta-analysis showed evidence of a harmful effect of tricyclic antidepressants compared with placebo on serious adverse events (OR 2.78; 95% CI 2.18 to 3.55; 35 trials), but the required information size was not reached. Only 2 out of 103 trials reported on quality of life and t-tests showed no evidence of a difference. CONCLUSIONS The long-term effects of tricyclic antidepressants and the effects on quality of life are unknown. Short-term results suggest that tricyclic antidepressants may reduce depressive symptoms while also increasing the risks of serious adverse events, but these results were based on low and very low certainty evidence. PROSPERO REGISTRATION NUMBER CRD42021226161.

Abstract
Depression is common in older adults and those with cardiovascular disease. Although selective serotonin reuptake inhibitors generally have been shown to be safe to treat depression in these patients, it is important to identify additional antidepressants when selective serotonin reuptake inhibitors are not effective. This qualitative narrative review summarizes what is known about the cardiovascular side effects of some of the newer antidepressants. Twelve novel non-selective serotonin reuptake inhibitor antidepressants were identified from the literature: venlafaxine, desvenlafaxine, duloxetine, milnacipran, levomilnacipran, mirtazapine, bupropion, vilazodone, vortioxetine, agomelatine, moclobemide, and ketamine-esketamine. A search restricted to publications written in English was conducted in PubMed and Google Scholar with the following search criteria: the specific antidepressant AND (QT OR QTc OR "heart rate" OR "heart rate variability" OR "hypertension" OR "orthostatic hypotension" OR "cardiovascular outcomes" OR "arrhythmia" OR "myocardial infarction" OR "cardiovascular mortality") AND (geriatric OR "older adults" OR "late life depression" OR "cardiovascular disease" OR "hospitalized" OR "hospitalized"). The recommended use, dosing ranges, cardiovascular effects, and general advantages and disadvantages of each of the drugs are discussed. Levomilnacipran and vilazodone have not received enough study to judge their safety in older patients or in those with, or at high risk for, cardiovascular disease. There is at least some evidence for possible adverse events with each of the other newer antidepressants that could be of concern in these patients. Nevertheless, with careful administration and attention to the potential adverse reactions for each drug, these may provide safe effective alternatives for older adults and patients with cardiovascular disease who do not respond to selective serotonin reuptake inhibitor antidepressants. However, more research on the safety and efficacy of these drugs in these specific patient populations is urgently needed.

Predictors of treatment outcome in depression in later life: A systematic review and meta-analysis. J Affect Disord 2018; 227:164-182. [PMID: 29100149 DOI: 10.1016/j.jad.2017.10.008] [Citation(s) in RCA: 64] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2017] [Revised: 09/13/2017] [Accepted: 10/01/2017] [Indexed: 02/04/2023]
Abstract
BACKGROUND Predictor analyses of late-life depression can be used to identify variables associated with outcomes of treatments, and hence ways of tailoring specific treatments to patients. The aim of this review was to systematically identify, review and meta-analyse predictors of outcomes of any type of treatment for late-life depression. METHODS Pubmed, Embase, CINAHL, Web of Science and PsycINFO were searched for studies published up to December 2016. Primary and secondary studies reported treatment predictors from randomised controlled trials of any treatment for patients with major depressive disorder aged over 60 were included. Treatment outcomes included response, remission and change in depression score. RESULTS Sixty-seven studies met the inclusion criteria. Of 65 identified statistically significant predictors, only 7 were reported in at least 3 studies. Of these, 5 were included in meta-analyses, and only 3 were statistically significant. Most studies were rated as being of moderate to strong quality and satisfied key quality criteria for predictor analyses. LIMITATIONS The searches were limited to randomised controlled trials and most of the included studies were secondary analyses. CONCLUSIONS Baseline depression severity, co-morbid anxiety, executive dysfunction, current episode duration, early improvement, physical illnesses and age were reported as statistically significant predictors of treatment outcomes. Only the first three were significant in meta-analyses. Subgroup analyses showed differences in predictor effect between biological and psychosocial treatment. However, high heterogeneity and small study numbers suggest a cautious interpretation of results. These predictors were associated with various mechanisms including brain pathophysiology, perceived social support and proposed distinct types of depressive disorder. Further investigation of the clinical utility of these predictors is suggested.

Abstract
OBJECTIVE The generalizability of antidepressant efficacy trials (AETs) has been questioned. No studies have examined the inclusion/exclusion criteria used in placebo-controlled studies of late life depression and compared them to the criteria used in non-late life AETs. METHOD We conducted a comprehensive literature review of placebo-controlled AETs published from January, 1995 through December, 2014. We compared the inclusion/exclusion criteria used in the 18 studies of late life depression to those used in non-late life depression. RESULTS There were nine inclusion/exclusion criteria that were used in more than half of the late life depression AETs: minimum severity on a symptom severity scale (100.0%), significant suicidal ideation (77.8%), psychotic features during the current episode of depression or history of a psychotic disorder (94.4%), history of bipolar disorder (77.8%), diagnosis of alcohol or drug abuse or dependence (83.3%), presence of a comorbid nondepressive, nonsubstance use Axis I disorder (55.6%), episode duration too short (66.7%), and an insufficient score on a cognitive screen (88.3%) or the presence of a cognitive disorder (55.6%). There were some differences between the late life and non-late life depression studies-use of a screening measure of cognitive functioning, presence of a cognitive disorder such as dementia, and the minimum depression severity cutoff score required at baseline. CONCLUSIONS The inclusion/exclusion criteria in AETs of late life depression were generally similar to the criteria used in non-late life depression AETs. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Antidepressants have been shown to reduce the risk of depression recurrence in adults, justifying prolonged antidepressant maintenance therapy for most if not all patients. However, older depressed adults may be at increased risk for antidepressant adverse effects. This article discusses the benefits and hazards of continued treatment in elderly depressed patients, and indicates which patients should and should not receive maintenance phase antidepressants. Most clinical trials conducted so far suggest that prolonged antidepressant use in older adults is efficacious to reduce recurrence rates. The benefits of prolonged antidepressant use may not be restricted to preventing recurrence but also include preservation of overall well-being, social functioning, reduced mortality risk from medical disorders, and reduced risk of dementia. Although generally safe, the prolonged use of antidepressants has been associated with higher risk of osteopenia/osteoporosis (in particular the selective serotonin reuptake inhibitors) and cardiovascular toxicity (tricyclic antidepressants). Fewer data are available for special populations, like those with multiple medical comorbidities or those with dementia; thus, the benefits of prolonged antidepressant use are not clear in these individuals.

Abstract
This paper reviews the discovery and history of the use of irreversible monoamine oxidase (MAO) inhibitors (MAOIs) such as phenelzine, tranylcypromine and isocarboxazid, as well as the second generation selective and reversible MAOIs such as the MAO-A inhibitor, moclobemide and the MAO-B inhibitor, selegiline. Data for review were identified from a literature search of OvidSP Medline and PsycInfo performed in July 2012, using the subject terms and keywords of 'monoamine oxidase inhibitors', 'major depression', 'depressive disorder' and 'depression (emotion)'. The search was limited to papers published in the English language and from 2007 onward only. Irreversible MAOIs have the potential to treat the most challenging mood disorder patients including those with treatment-resistant depression, atypical depression and bipolar depression. Unfortunately, the use of irreversible MAOIs has been declining sharply due to lack of marketing and the excessive fears of clinicians. Moreover, few clinicians now have any experience, let alone comfort, in prescribing this class of antidepressants. The newer MAOIs are available as another option for the treatment of major depression but have not replaced the irreversible MAOIs for the specific sub-types of depression for which they are now recommended in most consensus guidelines and treatment algorithms. The pharmacology, drug interactions and dietary recommendations associated with the use of MAOIs are reviewed. With the appropriate dietary restrictions and attention to potential drug interactions with serotonin and noradrenaline agents this class of drugs can be used effectively and safely. The MAOIs still represent an important element in our therapeutic armamentarium. Despite recommendations by opinion leaders and consensus guidelines for the use of MAOIs in specific sub-types of depression, the prescription rate of MAOIs is far less than expected and is decreasing. The "bad reputation" and the lack of industry support for this class of agents (especially the irreversible MAOIs) must be overcome in order to continue to provide a potentially useful treatment for a very vulnerable yet substantial sub-population of mood disorder patients.

Abstract
BACKGROUND This systematic review evaluated all published double-blind, randomized controlled antidepressant trials (RCTs) of acute phase treatment of older depressed patients. METHODS Meta-analyses were conducted in 51 double-blind RCTs of antidepressants in older patients. The results were also compared with 29 double-blind RCTs that did not produce extractable data to enter the meta-analysis. RESULTS All classes of antidepressant (TCA's, SSRIs and other antidepressants) were more effective than placebo in achieving response. In achieving remission however, only pooling all 3 classes of antidepressants together showed a statistically significant difference from placebo. No differences were found in remission or response rates between classes of antidepressants. TCAs were also equally effective compared with SSRIs in achieving response in more severely depressed patients. The numbers needed to treat (NNT) were 14.4 (95% CI 8.3-50) for one additional remission to antidepressants compared with placebo and 6.7 (95% CI 4.8-10) for response. The results of the double-blind RCTs that did not produce extractable data to enter the meta-analysis were in concordance with the RCTs that were included in the meta-analysis. LIMITATIONS Only 4 RCTs were found that have not been published. Few studies have focused on severely depressed older people. CONCLUSIONS Antidepressant treatment in older depressed patients is efficacious. We could not demonstrate differences in effectiveness between different classes of antidepressants; this was also the case in more severely depressed patients.

Abstract
Alzheimer's disease is one of the most devastating brain disorders of elderly humans. It is an undertreated and under-recognized disease that is becoming a major public health problem. The last decade has witnessed a steadily increasing effort directed at discovering the etiology of the disease and developing pharmacological treatment. Recent developments include improved clinical diagnostic guidelines and improved treatment of both cognitive disturbance and behavioral problems. Symptomatic treatment mainly focusing on cholinergic therapy has been clinically evaluated by randomized, double-blind, placebo-controlled, parallel-group studies measuring performance-based tests of cognitive function, activities of daily living, and behavior. Cholinesterase inhibitors, including donepezil, tacrine, rivastigmine, and galantamine are the recommended treatment of cognitive disturbance in patients with Alzheimer's disease. The role of estrogen replacement, anti-inflammatory agents, and antioxidants is controversial and needs further study. Antidepressants, antipsychotics, mood stabilizers, anxiolytics, and hypnotics are used for the treatment of behavioral disturbance. Future directions in the research and treatment of patients with Alzheimer's disease include: applying functional brain imaging techniques in early diagnosis and evaluation of treatment efficacy; development of new classes of medications working on different neurotransmitter systems (cholinergic, glutamatergic, etc), both for the treatment of the cognitive deficit and the treatment of the behavioral disturbances; and developing preventive methods (amyloid p-peptide immunizations and inhibitors of β-secretase and γ-secretase).

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT A single nucleotide polymorphism in ABCB1, which encodes P-glycoprotein, has retrospectively been associated with symptoms of nortriptyline-induced postural hypotension in depressed patients. This finding needs to be replicated in independent studies before recommendations regarding pharmacogenetic testing can be made. WHAT THIS STUDY ADDS In a prospective study of healthy volunteers homozygous for ABCB1 (1236-2677-3435, TTT/TTT or CGC/CGC), a single dose of nortriptyline was administered, plasma exposure was determined and blood pressure and heart rate were monitored during posture change. No differences between ABCB1 haplotype groups were found in plasma exposure of nortriptyline and its active metabolites, E- and Z-10-hydroxynortriptyline. The heart rate response to posture change was increased with nortriptyline, whereas there was no difference in blood pressure response. However, no differences between haplotype groups were observed except that the pre dose heart rate response to standing was greater in the TTT than CGC homozygotes. The association between ABCB1 polymorphisms and nortriptyline-induced postural hypotension found in a previous study could not be confirmed. The results raise the possibility of a predisposition in heart rate response in the TTT homozygotes rather than an effect of nortriptyline. AIMS To investigate the influence of ABCB1 (1236-2677-3435) polymorphisms on nortriptyline pharmacokinetics and nortriptyline-induced postural hypotension in healthy volunteers. METHODS Genetic screening of 67 healthy volunteers identified eight CGC homozygotes and nine TTT homozygotes of ABCB1 (1236-2677-3435), who were administered a single dose of nortriptyline 25 mg. Plasma exposure of nortriptyline and its active metabolites, E- and Z-10-hydroxynortriptyline, was determined over 72 h. Heart rate and blood pressure responses to posture change (active standing and passive head-up tilt) were measured continuously using finger plethysmography. RESULTS There were no differences in plasma exposure between ABCB1 haplotype groups, as the geometric mean (95% CI) AUC(0,72 h) ratios were 0.98 (0.94, 1.03), 1.02 (0.96, 1.09) and 0.95 (0.80, 1.10) for nortriptyline, E- and Z-10-hydroxynortriptyline, respectively. The pre dose heart rate response to standing was greater in the TTT than CGC homozygotes (mean (95% CI) difference 7.4 (1.5, 13.4) beats min(-1) , P = 0.02). At t(max) at 8 h post dose, nortriptyline increased the heart rate response to posture change in all subjects with mean (95% CI) Δ heart rate values of 7.4 (3.6, 11.3) beats min(-1) on active standing (P = 0.0009) and 4.8 (2.0, 7.6) beats min(-1) on head-up tilt (P = 0.002), but no difference was observed between haplotype groups. There was no difference in blood pressure response to posture change in either group. CONCLUSION The association between ABCB1 polymorphisms and nortriptyline-induced postural hypotension found in the previous study could not be confirmed. The results raise the possibility of a predisposition in heart rate response in the TTT homozygotes rather than an effect of nortriptyline.

Abstract
BACKGROUND The limited use of nortriptyline for smoking cessation is likely due to concerns about its serious adverse effects. OBJECTIVE To examine the safety of nortriptyline at doses equivalent to those used in aiding smoking cessation. DATA SOURCES A systematic search of relevant articles in MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, CINAHL, PsychINFO, WHO publications and the Clinical Trials database (through November 2008). STUDY SELECTION All studies of nortriptyline at doses between 75 and 100 mg in any indication were reviewed. DATA EXTRACTION The quality of included studies was assessed based on the Jadad score. Data were extracted using a data extraction form. DATA SYNTHESIS From 442 potentially relevant articles identified, 17 studies met our selection criteria and were included for data analysis. Indications for nortriptyline in these studies were smoking cessation (eight studies), depression (five studies), neuropathic pain (three studies) and schizophrenia (one study). 2885 individuals participated in these studies, with exposure time ranging between 4 and 12 weeks. The major comparator used in these trials was placebo. Overall, no life-threatening events occurred in these studies. Orthostatic hypotension was significantly higher in nortriptyline users than in comparator groups (relative risk 2.8; 95% CI 1.4, 5.3). Other adverse events significantly associated with nortriptyline were anticholinergic-related effects including drowsiness, dizziness, gastrointestinal disturbance and dysgeusia. CONCLUSIONS Current evidence suggests that nortriptyline, at doses between 75 and 100 mg, is not significantly associated with serious adverse events when administered in patients without underlying cardiovascular disease.

Abstract
Major depressive disorder is a prevalent recurrent medical syndrome associated with inter-episodic dysfunction. The metabolic syndrome is comprised of several established risk factors for cardiovascular disease (i.e. abdominal obesity, dyslipidaemia, dysglycaemia and hypertension). The criterion items of the metabolic syndrome collectively represent a multi-dimensional risk factor for cardiovascular disease and type 2 diabetes mellitus. Extant evidence indicates that both major depressive disorder and the metabolic syndrome, albeit distinct, often co-occur and are possibly subserved by overlapping pathophysiology and causative mechanisms. Conventional antidepressants exert variable effects on constituent elements of the metabolic syndrome, inviting the need for careful consideration prior to treatment selection and sequencing. Initiating and maintaining antidepressant therapy should include routine surveillance for clinical and/or biochemical evidence suggestive of the metabolic syndrome.

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
BACKGROUND Depression is a relatively common experience in older adults. The syndrome is associated with considerable distress, morbidity and service commitment. Approximately two thirds of patients presenting with severe forms will respond to antidepressant treatment and the last twenty years has witnessed a great increase in the number of these drugs. Older, frail people are particularly vulnerable to side effects. OBJECTIVES The aims of this review were to examine the efficacy of antidepressant classes, to compare the withdrawal rates associated with each class and describe the side effect profile of antidepressant drugs for treating depression in patients described as elderly, geriatric, senile or older adults, aged 55 or over. SEARCH STRATEGY The Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register (CCDANCTR-Studies) was searched (2003-08-13). Reference lists of relevant papers and previous systematic reviews were hand searched for published reports and citations of unpublished studies. SELECTION CRITERIA Only randomised controlled trials were included. Trials had to compare at least two active antidepressant drugs in the treatment of depression. DATA COLLECTION AND ANALYSIS Reviewers extracted data independently. In examining efficacy, the reviewers assumed that people who died or dropped out had no improvement. Withdrawal rates irrespective of cause and specifically due to side effects were compared between drug classes. Relative risk (RR) for dichotomous data and weighted mean difference for continuous data were calculated with 95% confidence intervals (CI). Qualitative side effect data were reported in terms of ratios of side effects and percentage of patients experiencing specific side effects. MAIN RESULTS A total of 29 trials provided data for inclusion in the review. We were unable to find any differences in efficacy when comparing classes of antidepressants. However, as the trials contained relatively small numbers of patients, these findings may be explained by a type two error. Tricyclic antidepressants (TCAs) compared less favourably with selective serotonin reuptake inhibitors (SSRIs) in terms of numbers of patients withdrawn irrespective of reason (RR: 1.24, CI 1.04, 1.47) and number withdrawn due to side effects (RR: 1.30, CI 1.02, 1.64). Subgroup analyses demonstrated that TCA related antidepressants had similar withdrawal rates to SSRIs irrespective of reason of withdrawal (RR: 1.49, CI 0.74, 2.98) or withdrawal due to side effects (RR: 1.07, CI 0.43, 2.70). The qualitative analysis of side effects showed a small increased profile of gastro-intestinal and neuropsychiatric side effects associated with classical TCAs. AUTHORS' CONCLUSIONS Our findings suggest that SSRIs and TCAs are of the same efficacy. However, we have found some evidence suggesting that TCA related antidepressants and classical TCAs may have different side effect profiles and are associated with differing withdrawal rates when compared with SSRIs. The review suggests that classical TCAs are associated with a higher withdrawal rate due to side effect experience, although these results must be interpreted with caution due to the relatively small size of the review and the heterogeneity of the drugs and patient populations.

Abstract
BACKGROUND Ethical concerns have been raised regarding the continued use of placebo control groups in randomized controlled trials of antidepressant medications for major depressive disorder. These concerns may be especially relevant for geriatric patients who may experience significant morbidity related to major depressive disorder. METHODS Sixty-eight randomized placebo-controlled trials of antidepressant medication for major depressive disorder were examined, 6 of which measured response to medication and placebo in elderly patients. RESULTS Although this review is limited by the small number of studies focusing on older individuals, there are a number of similarities and some differences in geriatric studies in comparison to other studies of adults with major depressive disorder. In comparison to studies of younger adults, the proportion of patients responding to placebo in studies of older individuals was slightly higher, and the proportion of patients responding to active medication was lower, leading to a significantly reduced effect size. CONCLUSIONS The scientific importance of using control groups in studies of major depression poses ethical challenges. However, the substantial and variable response to placebo and the inability to predict accurately the response to placebo or medication raise serious doubts about the scientific value of trials of new medications in which there is no placebo group.

Abstract
This review addresses the pharmacotherapy of antidepressants in the elderly. We performed a search based on Medline and the Cochrane Library. In addition to a meta-analysis of 17 randomised controlled studies, 36 randomised controlled trials of patients over the age of 60 published between 1980 and 2005 in English met the selection criteria and were included. Existing evidence suggests that no one class of antidepressant drugs has been found to be more effective than another in the treatment of depression in the elderly. Although newer antidepressants are not more effective than older ones, they are better tolerated and are safe especially in overdose. The adverse effect data suggest modest superiority of selective serotonin reuptake inhibitors over tricyclic antidepressants. The evidence available indicates that antidepressant treatment of four weeks has a beneficial effect compared to placebo. As to prevention of relapse and recurrence, antidepressants should be continued for at least six months after good initial response. In patients with high risk of relapse, treatment should be continued for at least two years. Long-term efficacy has been shown for dosulepin, nortriptyline and citalopram. In patients with dementia with persistent and significant symptoms antidepressant treatment may be indicated. At present, clomipramine, citalopram and sertraline have been reported as being superior to placebo. There is a paucity of data on the use of antidepressants in very elderly individuals, patients with significant comorbidity and patients with dementia. More data on the effect of antidepressants in the elderly, especially in the over 80-age group are needed.

Abstract
Depression in the elderly is a major public health problem as untreated depression adversely impacts comorbid illnesses. It is important to develop safe and effective antidepressant therapies for older individuals. We performed a systematic review of all published randomized, placebo-controlled antidepressant medication trials in populations over age 55 years. Papers were obtained via MEDLINE (1966-August 2003) and PSYCINFO (1872-August 2003). Unpublished trials, trials examining nonpharmacologic interventions, and papers reporting post hoc analyses were not included in this review unless they provided new insights. A total of 18 placebo-controlled trials examining acute efficacy met our criteria. The combined sample size in these studies was 2252. The mean sample size was 51 (range 20-728) and mean trial duration was 7 weeks. A total of 12 trials examined tricyclic antidepressants (TCAs), five trials examined selective serotonin reuptake inhibitors (SSRIs), two trials examined bupropion, and one trial examined mirtazapine. There were no published trials of venlafaxine or nefazodone. In all, 71.5% of trials reported significantly greater efficacy with drug than placebo. In conclusions, there is a paucity of published controlled antidepressant trials in the elderly. Most published studies examine small sample sizes and do not include common comorbid conditions. Efficacy studies examining relapse prevention are lacking. Large placebo response rates, lack of controlled head to head comparisons, and other methodological design differences make crosstrial comparisons difficult. Large simple studies are urgently needed to address the unmet needs for data on safety and efficacy of antidepressants in this population.

Abstract
BACKGROUND Placebo effects in major depressive disorder (MDD) have received much interest in the medical literature. However, few quantitative analyses have been done in homogeneous populations. OBJECTIVE To determine efficacy rates for placebo in patients with MDD; to quantify the correlation between efficacy and publication year, as well as between placebo and drug response rates. DESIGN Searching MEDLINE (1966-December 2000), EMBASE (1998-February 2001), HealthSTAR (1975-December 2000), and Cochrane (1980-December 2000) databases, randomized, placebo-controlled trials were retrieved including patients with MDD as defined by Diagnostic and Statistical Manual of Mental Disorders, 3rd and 4th editions criteria, Hamilton Rating Scale for Depression score >/=18 or Montgomery-Asberg Depression Rating Scale score >/=16, reporting successes as 50% decreases in scores after 6-8 weeks of treatment. Response rates were summarized using a random effects meta-analysis for per protocol (PP) and intent-to-treat (ITT) results. RESULTS We included 24 of 134 potential studies examining 4459 patients, 1786 on placebo and 2673 on an antidepressant. Placebo response rates were 45.5% (PP) and 26.9% (ITT). Correlations were significant between year and rates (PP rho 0.448, p = 0.042; ITT rho 0.557; p = 0.006), but not for active drugs. Placebo and drug rates were correlated (PP r 0.397, p = 0.020; ITT r 0.539; p = 0.002). CONCLUSIONS These placebo rates confirm those reported previously, but were from a homogeneous population. Although statistically significant, the correlation between drug and placebo rates was lower than others reported. During the study period, placebo rates increased linearly; active drugs did not. Correlations between placebo and drug response rates reflected moderate to strong effect sizes. We suggest that current methodology has been unsuccessful in achieving unbiased double-blind conditions not influenced by extra-trial factors, including time.

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
BACKGROUND Depressive symptoms in late life are a major concern as they increase disability and aggravate existing medical conditions. Depression is underrecognised and undertreated in the elderly, be it due to somatic symptoms, comorbid physical illness or anxiety, or because it is accepted as a normal feature of ageing. There is little doubt that effective and well-tolerated antidepressant therapy is required. OBJECTIVE This paper reviews the antidepressant treatment options for late-life depression (selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, mixed noradrenergic and serotonergic agents), in terms of their efficacy, safety and pharmacokinetics in elderly patients. RESULTS In addition to proven efficacy, selection of an antidepressant agent for late-life depression must be based on an understanding of safety and pharmacokinetic issues associated with each agent. Comorbid conditions and lifestyle characteristics of the elderly that are different to those encountered in the younger adult population should also be considered. CONCLUSIONS To date, published clinical evidence in the elderly suggests that the first-choice agents for treating late-life depression are the SSRIs.

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
OBJECTIVES To make direct comparisons between studies of antidepressant treatment of older people using Number Needed to Treat (NNT) analysis. METHODS Medline and Embase Search 1966-1999 and contact with manufacturers of antidepressant drugs asking for any relevant data on file; NNT analyses of outcome in terms of efficacy and adverse effects. RESULTS Most antidepressant trials show efficacy; this is less clear for moclobemide and fluoxetine. Head-to-head comparisons between antidepressants showed significant superiority for paroxetine over fluoxetine and a trend in favour of SSRIs and venlafaxine over tricyclics. CONCLUSIONS NNT analysis is one way of providing intelligible information on antidepressant efficacy and adverse effects which can inform clinical decisions. LIMITATIONS Many studies do not present data in a form amenable to NNT analysis. Most head-to-head comparisons between antidepressants are underpowered.

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
OBJECTIVE The aim of this study was to determine whether age itself is a significant factor in predicting adverse drug reactions in depressed inpatients treated with clomipramine. METHOD The study involved 150 hospitalized, depressed patients treated with 150 mg clomipramine per day. Changes in orthostatic blood pressure during treatment as well as the patients' complaint about side-effects was examined with regard to age. The sample was divided into younger (<56) and older (56-70) groups. RESULTS No significant differences between younger and older subjects were found on any of the 44 side-effects recorded. However, older depressed patients suffer from more pronounced orthostatic hypotension than younger patients. CONCLUSION Older depressed patients who have been treated with clomipramine suffer from more severe orthostatic hypotension than younger patients. However, with the right precautions it is safe to treat older patient up to the age of 70 years with a tricyclic antidepressant.

Abstract
BACKGROUND Depression is the most prevalent psychiatric disorder in the elderly and several studies indicate that 10-15% of persons over 65 years suffer from significant depressive symptoms. Despite the high prevalence, most cases of depression in the elderly remain unrecognized and untreated, maybe because of a different pattern of symptoms across age groups. The objective of the study was to compare symptomatology and diagnostic profile between younger and elderly DSM-III and DSM-III-R major depressed inpatients and to advise an appropriate depression scale for the elderly. METHODS The study covers 461 depressed inpatients evaluated with the Hamilton Depression Scale and the Newcastle 1965 Scale. To find differences between younger and elderly patients, the symptomatology was analyzed stepwise by principal component analyses, latent structure analyses and single item analyses. RESULTS No clinically significant differences in symptomatology between younger and elderly depressed patients were found. The DSM-IV concept of Major Depression and the ICD-10 criteria for depression was not influenced by patients' age. LIMITATIONS All patients were hospitalized and mainly endogenously depressed and generalization of the results to other populations should be made with caution. Only pretreatment data was analyzed. CONCLUSIONS The DSM-IV concept of Major Depression and the ICD-10 criteria for depression can be used without modification for age.

Abstract
BACKGROUND Depression warranting intervention is found in ten percent of people over the age of 60. Older depressed people are more likely to die than non-depressed. Relatively few receive therapeutic interventions, and those that do, tend to receive low dose antidepressant therapy. Depression in older people is thought to differ in terms of aetiology, presentation, treatment and outcome than in younger people. Concomitant physical illness and increasing social, physical and neurophysiological diversity are associated with the ageing process. Consequently drug treatment of older patients is often carried out in institutions and on patients suffering from multiple physical problems. OBJECTIVES To determine the efficacy of antidepressant medication compared with placebo in the treatment of depression in older patients. SEARCH STRATEGY The search strategy incorporated: electronic literature searches of databases held by the Cochrane Collaboration Depression, Anxiety and Neurosis Review Group (CCDAN) (see Collaborative Review Group Search Strategy). Reference lists of related reviews and references of located studies. Contact was made with authors working in the field. SELECTION CRITERIA All randomised, placebo controlled trials using antidepressants in the treatment of the presenting episode of depression in patients described as elderly, geriatric senile or older adult. DATA COLLECTION AND ANALYSIS Two types of data were extracted (if available) from each study. The first type of data was dichotomous data, this consisted of recovered/not recovered. The second, continuous data,included: Hamilton Depression Rating Scale (HAM-D), Montgomery-Asberg Rating Scale (MADRS) and other depression rating scale scores. An analysis using Peto Odds ratios for the dichotomous data and weighted mean difference for continuous data was performed using RevMan 3.1. The presence of heterogeneity of treatment effect was assessed. MAIN RESULTS Seventeen trials contributed data to the analyses comparing the efficacy of antidepressant treatment and placebo. Analyses of efficacy was based on 245 patients treated with TCAs (223 with placebo), 365 patients treated with SSRIs (372 with placebo) and 58 patients treated with MAOIs (63 with placebo). The standardised effect size for the three groups respectively were: TCAs; OR: 0.32 (0.21,0.47), SSRIs; OR; 0.51 (0.36,0.72), MAOIs: 0.17 (0.07,0.39). REVIEWER'S CONCLUSIONS TCAs, SSRIs and MAOIs are effective in the treatment of older community patients and inpatients likely to have severe physical illness. At least six weeks of antidepressant treatment is recommended to achieve optimal therapeutic effect. There is little evidence concerning the efficacy of low dose TCA treatment. Further trials are required before low dose TCA treatment is routinely recommended.

Abstract
Monoamine oxidase inhibitors (MAOIs) are mainly used in psychiatry for the treatment of depressive disorders and in neurology for the treatment of Parkinson's disease. While the classical, nonselective and nonreversible MAOIs, such as phenelzine and tranylcypromine, are characterised by the risk of inducing a hypertensive crisis when dietary tyramine is ingested, the selective monoamine oxidase-B (MAO-B) inhibitor selegiline (deprenyl) and, even more so, the selective and reversible monoamine oxidase-A (MAO-A) inhibitor moclobemide, are free from this potential interaction. Drug tolerability data for the elderly show that moclobemide is one of the most well tolerated compounds. Selegiline, especially when used in combination with levodopa, can cause anorexia, dry mouth, dyskinesia and, most problematic, orthostatic hypotension. For the traditional MAOIs, phenelzine and tranylcypromine, published data are insufficient to be able to give a conclusive tolerability statement regarding the use of these compounds in elderly people. Although orthostatic hypotension occurs in most patients treated with traditional MAOIs, the incidence in elderly patients with depression does not appear to be greater than that reported with tricyclic antidepressants.

Abstract
OBJECTIVE To review the efficacy and safety of moclobemide in comparison with TCAs (for our purposes, "TCAs" will represent tricyclic and tetracyclic antidepressants, including maprotilin and mianserin) and selective serotonin reuptake inhibitors (SSRIs) in elderly depressed patients. METHODS The efficacy data reviewed were obtained from the following sources: 1) results of published studies in the elderly; 2) data on patients aged > or = 60 years extracted from all available controlled trials in adults (> or = 18 years) in which moclobemide was compared with TCAs or SSRIs; and 3) the adverse events were extracted for patients aged > or = 60 years from the safety data base of all available comparative short-term studies with moclobemide versus TCAs, SSRIs, or placebo and of long-term studies with moclobemide. RESULTS The data show that moclobemide is an effective antidepressant in depressed patients aged > or = 60 years. The response rate to moclobemide was 50% to 55% in this population. Moclobemide was more effective than placebo and was of similar efficacy to the TCAs and the more recently introduced SSRIs. The tolerability of moclobemide was rated as "very good" or "good" in almost 90% of these patients, which was better than the tolerability of TCAs and similar to that of SSRIs. Patients without any adverse events were more frequently found in the moclobemide group than in those treated with TCAs (P < 0.01) or SSRIs (P < 0.01). Adverse events of the anticholinergic type were more frequent with TCAs than with moclobemide (P < 0.001), and nausea was found 3 times more frequently with SSRIs than with moclobemide (P < 0.01). CONCLUSIONS Moclobemide is an effective and well-tolerated antidepressant for the treatment of elderly depressed patients.

Abstract
BACKGROUND To determine the efficacy, safety and tolerability of antidepressants in depressed elderly patients. METHODS Search for randomized controlled double-blind studies evaluating atypical antidepressants (ATYPs), reversible inhibitors of monoamine oxidase-A, selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants in moderate/severe depressed patients > or = 60 years for > or = four weeks. The random effects model (single-arm; comparative) was used to aggregate efficacy, safety and dropout. RESULTS No difference in single-arm aggregation of outcomes for four antidepressant classes. Comparative analyses showed no statistical difference between outcomes, except SSRIs had a higher response rate than ATYPs. CONCLUSION Elderly show no differences in antidepressant class outcomes. LIMITATIONS Heterogeneity and lack of power. CLINICAL RELEVANCE There is little advantage for antidepressant classes over another in the aged.

Abstract
The dexamethasone suppression test (DST) was conducted in 95 elderly DSM-III-R depressed patients randomized for treatment with moclobemide (MOC; 400 mg daily), nortriptyline (NT; 75 mg daily), or placebo (PBO) in a 7-week double-blind multicenter study. Patients were assessed weekly using various clinical scales, including the 17-item Hamilton Depression Rating Scale. The DST was administered at baseline and at the end of treatment. At baseline, no relationship was found between DST status and the various clinical scales used. At the end of treatment, suppressors (DST-) had significantly improved clinical ratings compared to nonsuppressors (DST+), and were mostly found among those treated with NT (71%) as compared to MOC (41%) or PBO (33%) (p < .03). On the other hand, baseline DST measures influenced treatment outcome; DST+ patients had a greater number of treatment responders to NT (48%) than MOC (19%) or PBO (20%) (p < .07). For DST- patients, the situation was reversed: NT, 7%; MOC, 31%. Postdexamethasone cortisol levels were lower in MOC responders (p < .07). An interaction was found between DST and drug-specific response. The DST may be a useful adjunct for predicting and evaluating the outcome of antidepressant therapy.

Abstract
Brofaromine is a selective and reversible inhibitor of monoamine oxidase A. The efficacy and safety of this compound as compared with tricyclic antidepressants, classical monoamine oxidase inhibitors and placebo has been demonstrated in several clinical trials. The present 6-week, double-blind, randomized trial compared brofaromine with imipramine in in-patients with major depression. Brofaromine was as effective as imipramine in the treatment of major depression, but exhibited a different side-effect profile, in particular lacking the anticholinergic and certain cardiovascular side-effects of the tricyclic imipramine, but more likely to induce sleep disturbances. In this study, in-patients were examined, since the majority of controlled clinical trials on depressed patients conducted so far have focused on the evaluation of out-patients. If one assumes that a different degree of severity of depression exists between these two patient groups, then the results of those trials conducted on out-patients cannot readily be transferred to in-patients.

Abstract
The Major Depression Rating Scale (MDS) has been derived from the Hamilton Depression Scale and the Melancholia Scale. The MDS contains the nine DSM-IV items for major depression which all have anchoring scores from 0 to 4; hence, the theoretical score range is up to 36. The Major Depression Rating Scale has in this study been psychometrically analysed in randomized moclobemide trials. The results showed that the MDS had higher internal validity than the Hamilton Depression Scale. Thus, the homogeneity of the items was higher; factor analysis identified only one general depression factor (after 4 weeks of treatment explaining more than 50% of the variance). The inter-rater reliability of the two scales was of the same high level. The ability to measure changes (external validity) was tested in randomized clinical trials with moclobemide versus tricyclics (clomipramine and notriptyline) performed in Denmark in the psychiatric setting as well as in the general practice. The results showed that in the psychiatric setting tricyclics were superior to moclobemide with effect sizes ranging between 0.43 and 0.53. The highest effect size was obtained with the Melancholia Scale and the Major Depression Rating Scale, while the Hamilton Depression Scale was below 0.50. In the general practice setting no difference was found between moclobemide and clomipramine. In conclusion, the Major Depression Rating Scale has been found to have a more homogeneous factor structure than the Hamilton Depression Scale, but still with the same level of reliability and external validity. However, studies are needed to standardize the scale, especially in the general practice setting.

Abstract
Psychopharmacotherapy of the elderly must take into account the effects of age-related changes in the structure and function of the brain and various organs. In general, older people are more sensitive than young people to both the therapeutic and toxic effects of psychotropic medications, necessitating lower doses and longer dosage intervals. This holds true for the treatment of 5 major types of psychiatric illness (depression, bipolar disorder, anxiety, psychotic disorders and dementia). The tricyclic antidepressants, although efficacious, inexpensive, and backed by 30 years of experience, are less well tolerated by the elderly than are newer antidepressants such as the selective serotonin uptake inhibitors. Problems with monoamine oxidase (MAO) inhibitors, including orthostatic hypotension and restrictions in diet and other medication use, have been overcome by the advent of reversible selective inhibitors of MAO-A, but the efficacy of these in the elderly has yet to be proven in clinical trials. Lithium remains the mainstay for the treatment of bipolar disorder. However, careful dosing and monitoring of plasma lithium concentrations are required in the elderly due to changes in pharmacokinetics and pharmacodynamics which make older patients very sensitive to the toxic effects of this medication. Similarly, age-related changes in the pharmacokinetics and pharmacodynamics of the benzodiazepines, the most frequently prescribed medications for anxiety in the elderly, result in recommendations for lower doses and preferential use of those agents metabolised by conjugation (e.g. oxazepam). Buspirone, a partial serotonin 5-HT1A-agonist which is better tolerated than benzodiazepines in the elderly, may be used as an alternative. The elderly are extremely sensitive to extrapyramidal adverse effects which the typical antipsychotics (neuroleptics) exhibit to varying extents. The selection of a suitable agent for the treatment of a psychotic disorder should be based upon the adverse effect profile of the drug and the specific symptoms and situation of the patient. The newer atypical antipsychotics, clozapine and risperidone, have yet to be well-studied in the elderly. Dementia, exemplified by Alzheimer's disease, is almost exclusively an illness of the elderly. Only one medication, tacrine, has been approved for its treatment, based on extensive basic research and positive results of several clinical trials. Its long-term benefits have yet to be determined and it has several adverse effects, including a tendency to increase liver enzymes to the extent that the medication has to be discontinued.(ABSTRACT TRUNCATED AT 400 WORDS)
