Abstract
BACKGROUND Escitalopram is selective serotonin reuptake inhibitors (SSRIs) and one of the most commonly prescribed newer antidepressants (ADs) worldwide. We aimed to explore the efficacy, acceptability and tolerability of escitalopram in comparison with other ADs in the acute-phase treatment of major depressive disorder (MDD). METHODS Medline/PubMed, EMBASE, the Cochrane Library, CINAHL, and Clinical Trials.gov were searched from inception to July 10, 2023. Trial databases of drug-approving agencies were hand-searched for published, unpublished and ongoing controlled trials. All randomized controlled trials comparing escitalopram against any other antidepressant for patients with MDD. Responders and remitters to treatment were calculated on an intention-to-treat basis. For dichotomous data, risk ratios (RRs) were calculated with 95% confidence intervals (CI). Continuous data were analyzed using standardized mean differences (with 95% CI) using the random effects model. RESULTS A total of 30 studies were included in this meta‑analysis, among which sixteen trials compared escitalopram with another SSRI and 14 compared escitalopram with a newer AD. Escitalopram was shown to be significantly more effective than citalopram in achieving acute response (RR 0.67, 95% CI 0.50-0.87). Escitalopram was also more effective than citalopram in terms of remission (RR 0.53, 95% CI 0.30-0.93). CONCLUSIONS Escitalopram was superior to other ADs for the acute phase treatment of MDD in terms of efficacy, acceptability and tolerability. However, no significant difference was found between escitalopram and other ADs in early response or follow-up response to treatment of MDD.

Abstract
Purpose Selective serotonin reuptake inhibitors (SSRIs) are the preferred treatments for depression. The most common adverse drug reactions are symptoms involving the digestive system, leading to low compliance in patients with depression. Therefore, it is important to assess the safety of SSRIs with respect to the digestive system. Several meta-analyses have compared the risks of digestive side effects of SSRIs and other antidepressants. We aimed to compare the risks of various SSRIs (fluoxetine, escitalopram, citalopram, paroxetine, and sertraline) for adverse reactions of the digestive system. Methods Systematic searches returned 30 randomized controlled trials (n = 5004) of five antidepressants and placebos. Results Fluoxetine had the lowest probability of digestive side effects, ranking fifth at 0.548. Sertraline had the highest probability of digestive side effects, with a probability of 0.611. For gastrointestinal tolerability, escitalopram was better than paroxetine (odds ratio [OR] =0.62, 95% confidence interval [CI] 0.43–0.87) and sertraline (OR=0.56, 95% CI 0.32–0.99). Conclusion Fluoxetine exhibited distinct advantages compared to other SSRIs, while sertraline had the greatest likelihood of digestive system side effects. These findings will help doctors understand the relative advantages of various antidepressants.

Abstract
Abstract
Background
Antidepressant response is a complex trait influenced by clinical, demographic and genetic factors.
Objectives
To explore the influences of baseline depression severity, gender and type of depressive episode on efficacy and safety of escitalopram (10–20 mg/day) in South Indian patients with major depressive disorder (MDD).
Methods
The study was conducted on 18–65-year-old patients (n = 151) suffering from a first or recurrent episode of MDD with a 17-item Hamilton Depression Rating Scale (HDRS-17) score of ≥ 18 at baseline. Efficacy assessments were done using HDRS-17, Montgomery-Asberg Depression Rating Scale (MADRS), and Clinical Global Impression (CGI) at baseline and weeks 4, 8 and 12. Patients were monitored for adverse drug reactions (ADRs). Clinical outcomes were compared among various groups based on gender, type of depressive episode (first or recurrent episode) and baseline HDRS-17 scores (moderate depression—score between 17 and 23; severe depression—score ≥ 24).
Results
Among the 148 subjects who completed the 12-week study, 43.9% and 42.6% achieved response and remission, respectively. The decline in HDRS-17 and MADRS scores from baseline was significant (p value < 0.05) at all follow-up visits and a similar pattern was seen with CGI. Efficacy outcomes were better in the moderate baseline depression group compared with severe depression. There were no associations of efficacy with gender and type of depressive episode. A total of 247 adverse drug reactions (ADR) were reported and 119 (80.41%) subjects experienced at least one ADR during the study period. No serious ADR was reported. Male patients experienced more ADRs compared with females. The safety profile of escitalopram was similar across various groups based on baseline depression severity and type of depressive episode.
Conclusion
The study revealed that escitalopram is efficacious in south Indian MDD patients with a favourable safety profile. The efficacy was influenced by baseline depression severity whereas more ADRs were reported by male patients.

Abstract
The intestinal microbiota plays an important role in the pathophysiology of depression. As determined, the microbiota influences the shaping and modulation of the functioning of the gut-brain axis. The intestinal microbiota has a significant impact on processes related to neurotransmitter synthesis, the myelination of neurons in the prefrontal cortex, and is also involved in the development of the amygdala and hippocampus. Intestinal bacteria are also a source of vitamins, the deficiency of which is believed to be related to the response to antidepressant therapy and may lead to exacerbation of depressive symptoms. Additionally, it is known that, in periods of excessive activation of stress reactions, the immune system also plays an important role, negatively affecting the tightness of the intestinal barrier and intestinal microflora. In this review, we have summarized the role of the gut microbiota, its metabolites, and diet in susceptibility to depression. We also describe abnormalities in the functioning of the intestinal barrier caused by increased activity of the immune system in response to stressors. Moreover, the presented study discusses the role of psychobiotics in the prevention and treatment of depression through their influence on the intestinal barrier, immune processes, and functioning of the nervous system.

Abstract
BACKGROUND Antidepressant efficacy is influenced by patient expectations and, in randomized controlled trials (RCTs), the probability of receiving a placebo. It is unclear whether tolerability demonstrates a similar pattern. This study aimed to determine whether study design influences adverse event (AE) rates in antidepressant trials for subjects receiving active treatment or placebo. METHODS RCTs comparing one antidepressant to another antidepressant, placebo, or both in major depressive disorder (MDD) (1996-2018) were retrieved from Medline and PsycINFO. Clinicaltrials.gov was searched for unpublished trials. Of 1,997 studies screened, 77 trials were included. Studies were classified as drug-drug, drug-drug-placebo, or drug-placebo based on design and overall number of subjects experiencing any AE was recorded. Subgroup meta-analysis of proportions and meta-regression techniques were used to compare AE rates across study designs in patients receiving active antidepressant treatment and placebo. RESULTS Among the actively treated, AE rates were lower in drug-drug trials (58.5%) compared to drug-drug-placebo (75.7%) and drug-placebo (76.4%) (the model reported coefficients for percent differences between AE rates of different study designs were B=17.0, p<0.001 and B=17.8, p<0.001, respectively). AE rates in patients receiving placebo were not different between study designs. LIMITATIONS The present study is limited by the diverse range of study populations, variability in reporting of AEs, and specific antidepressants employed in the included trials. CONCLUSIONS The inclusion of a placebo arm in the study design was unexpectedly associated with higher rates of AEs among patients receiving active medication in antidepressant trials. This observation has important implications for interpretation of trial tolerability findings.

Hamilton scale and MADRS are interchangeable in meta-analyses but can disagree at trial level. J Clin Epidemiol 2020; 124:106-117. [PMID: 32387423 DOI: 10.1016/j.jclinepi.2020.04.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 04/13/2020] [Accepted: 04/29/2020] [Indexed: 11/24/2022]
Abstract
BACKGROUND AND OBJECTIVE Major depressive disorder is a multidimensional disease, in which demonstrating the efficacy of treatments is difficult. The Hamilton Rating Scale for Depression (HRSD) and the Montgomery-Asberg Depression Rating Scale (MADRS) cover different domains but are used interchangeably as primary measures of the outcome in trials and-with standardized measures-in meta-analyses. We aimed at understanding (i) whether the choice of the outcome measurement tool can influence the outcome of a trial, and if so, (ii) whether one systematically outperforms the other, and (iii) whether using standardized measures of the effect in meta-analysis is justified. METHODS Short-term randomized trials in patients with major depressive disorder that used both the scales were systematically searched and the results were collected. To quantify the differences in the results-both in terms of the standardized mean difference (SMD) and odds ratio (OR) for response-and their range, data were analyzed and plotted with the Bland-Altman method. RESULTS 161 comparisons from 80 studies were included, involving a total of 18,189 patients. Neither of the two scales appears systematically more sensitive to the treatment effect than the other in terms of SMDs (P-value = 0.06, 95% CI -0.044 to 0.001) or ORs (P-value = 0.15, 95% CI -0.25 to 0.04). However, the variability of differences between the HRSD and MADRS largely depends on the number of patients included in the comparison. CONCLUSION No systematic differences between the two scales were found supporting the use of standardized measures in meta-analyses. However, the same trial may give very different results with either scale, especially in small trials. Further research is needed to understand the causes of this variability.

Abstract
BACKGROUND This study evaluated the non-inferiority of bupropion extended-release (XL) compared to escitalopram for acute-phase treatment of Chinese patients with major depressive disorder (MDD). METHODS This randomized (1:1), double-blind, active-control study conducted between February 2015 and October 2016 included patients with MDD (DSM-IV) (N = 538). The treatment phase had three dose levels (level 1 [Week 1], level 2 [Week 2-4], and level 3 [Week 5-8]), which included either bupropion XL 150 mg, 300 mg, 300 mg or escitalopram 10 mg, 10 mg, 10-20 mg (once-daily), respectively. Primary outcome was mean change from baseline in Hamilton Depression Rating Scale-17 (HAMD-17) total score at Week 8. RESULTS Overall, 534 patients (bupropion XL, n = 266; escitalopram, n = 268) received at least one dose of study medication. The least square mean (standard error) change from baseline in HAMD-17 total score at Week 8 was -14.5 (0.41) in bupropion XL group and -15.4 (0.39) in escitalopram group (mean difference: 0.8 [-0.27, 1.94]). The response rate was 69.6% versus 72.9%, remission rate was 39.7% versus 47.2%, sustained response rate was 51.6% versus 56.3%, and sustained remission rate was 25.5% versus 28.6%, respectively, for bupropion XL versus escitalopram group. Adverse events were reported by 313 patients (bupropion XL, n = 157; escitalopram, n = 156); the most common on-treatment adverse event in both groups was nausea (10.5% versus 18.7%, respectively). LIMITATIONS A non-inferiority short-term (8 weeks) study without a placebo arm. CONCLUSION Results from this study demonstrated that the efficacy of bupropion XL was non-inferior to that of escitalopram in Chinese patients with MDD.

Abstract
Severe depression accounts for one-third of depressed patients. Increasing severity of depression usually hinders patients from achieving remission. This study evaluated the efficacy and safety of escitalopram in acute-phase treatment of severe major depressive disorder (MDD). A total of 225 participants with severe MDD (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria), with a current depressive episode and Montgomery-Asberg Depression Rating Scale (MADRS) score of ≥30 were enrolled. Participants received flexible dose escitalopram (10-20 mg/d) treatment for 8 weeks. Symptoms status was assessed by MADRS, Hamilton Depression Rating Scale (HAM-D-17), and Hamilton Anxiety Rating Scale (HAM-A). Quality of life was assessed by Short Form-12 (SF-12) and safety by adverse events, laboratory investigations, vital signs and physical findings. The remission (MADRS total score ≤ 10) rate in the intent-to-treat set (n = 207) was 72.9% at week 8. Significant improvement in symptoms compared to baseline, as evaluated by MADRS, HAMD-17 and HAMA scores at baseline, week 1, week 2, week 4, and week 8 (p < 0.0001 for all), was noted. Mean (SD) reduction from baseline in MADRS total score was 26.6 (11.38). Improvements in SF-12 score were significant (p = 0.000) and positively related to symptom improvement and negatively related to treatment-emergent adverse events (TEAEs). TEAEs were reported in 28.38% of participants. Most common TEAEs (>4%) were somnolence (9.0%), nausea (7.7%), hyperhidrosis (4.5%), dry mouth and dizziness (4.1% each). No serious TEAEs were reported. Escitalopram was effective and well-tolerated for acute-phase treatment of severe depression in Chinese population.

Abstract
BACKGROUND Significant anxiety symptoms are associated with poor clinical course and outcome in major depressive disorder (MDD). This single-arm, open-label study aimed to evaluate the efficacy and tolerability of escitalopram treatment in patients with MDD and anxiety symptoms. METHODS Adult patients with MDD and anxiety symptoms (Montgomery-Asberg Depression Rating Scale [MADRS] ≥22 and Hamilton Anxiety Rating Scale [HAM-A] ≥14) were enrolled and received escitalopram (10-20 mg/day) treatment for 24 weeks. Symptom status was assessed by MADRS, 17-item-Hamilton Depression Rating Scale, HAM-A, and Clinical Global Impression Scale at baseline and the following visits. Quality of life was assessed by Short Form-12, and safety was evaluated by adverse events, laboratory investigations, vital signs, and physical findings. RESULTS Overall, 200 of 318 (66.2%) enrolled patients completed the 24-week treatment. The remission (MADRS ≤10 and HAM-A ≤7) rate in the full analysis set (N=285) was 73.3% (95% confidence interval: 67.80, 78.38) at week 24. Mean (± standard deviation) MADRS total score was 33.4 (±7.13) and HAM-A score was 27.6 (±7.26) at baseline, which reduced to 6.6 (±10.18) and 6.0 (±8.39), respectively, at week 24. Patients with higher baseline depression and anxiety level took longer to achieve similar remission rates. Overall, 80 of the 302 (26.5%) patients included in the safety set reported at least 1 treatment-emergent adverse event (TEAE). Most frequently reported TEAEs (>2%) were headache (4.0%), nasopharyngitis (3.6%), nausea (3.0%), and dizziness (2.6%). Serious TEAEs were reported by 1.3% patients; no deaths were reported. CONCLUSION Escitalopram 10-20 mg/day was effective and well-tolerated in the long-term treatment of MDD with anxiety symptoms in adult Chinese population.

Abstract
BACKGROUND Although psychomotor retardation (PR) and cognitive disfunctioning are essential symptoms of elderly depressed patients, the differential effect of treatment with an SSRI in the elderly on these symptoms has hardly got any attention in studies with objective experimental measures. Since effects appear relatively slower in elderly, this study evaluates the effect on cognitive and psychomotor functioning as compared to mood, on four points during a twelve week follow up of monotreatment with escitalopram. METHOD 28 non-demented elderly unipolar depressive patients on 5-20mg escitalopram were compared to 20 matched healthy elderly. All participants underwent a test battery containing clinical depression measures, cognitive measures of processing speed, executive function and memory, clinical ratings of PR, and objective computerized fine motor skill-tests at the start and after 2, 6 and 12 weeks. Statistical analysis consisted of a General Linear Model (GLM) repeated measures multivariate analysis of variance of completers to compare the psychomotor and cognitive outcomes of the two groups. RESULTS Although, apart from the significant mood effect, no interaction effects were found for the psychomotor and cognitive tasks, the means in general show a trend of differential effects in cognitive and psychomotor functions, with smaller effects and delayed timeframes and with presence of subgroups compared to mood effects. LIMITATION Longer follow up studies are necessary to evaluate differential long term effects. CONCLUSION In elderly, moderate effects of SSRI treatment on mood precede slow or limited effects on cognition and psychomotor retardation.

Abstract
BACKGROUND Major depressive disorder (MDD) impacts health, quality of life and workplace productivity. Antidepressant treatment is the primary therapeutic intervention. This study assessed the efficacy and tolerability of new generation antidepressants and their cost-effectiveness in the Singapore healthcare system. METHODS We conducted a systematic search for head-to-head randomised controlled trials on ten antidepressants (agomelatine, duloxetine, escitalopram, fluvoxamine, fluoxetine, mirtazapine, paroxetine, sertraline, trazodone and venlafaxine) employed as monotherapy in acute MDD management. We performed a network meta-analysis to compare their relative efficacy. The outcome measures for efficacy were response and remission rate, and mean change in Hamilton Depression Rating Scale (HDRS) score; and for tolerability, study withdrawal rates due to adverse events. To evaluate their relative cost effectiveness, a decision tree simulating a cohort of MDD patients using antidepressant as monotherapy was constructed from a societal perspective over 6 months. We used effectiveness data from our network meta-analysis and local data on resource use for depression in Singapore. The incremental cost expected for each additional quality-adjusted life-year (QALY) gained was calculated and presented as the incremental cost-effectiveness ratio (ICER). RESULTS We identified 76 relevant articles for the network meta-analysis. Of the ten agents included in the analysis, mirtazapine and agomelatine were most efficacious in achieving response and remission, respectively. Mirtazapine and duloxetine resulted in the greatest magnitude of change in the HDRS score. Agomelatine, escitalopram and sertraline were the best tolerated of the drugs analysed, while duloxetine was the least well tolerated drug. Using a composite outcome of efficacy (response and remission rates) and tolerability, agomelatine, escitalopram and mirtazapine were the favoured treatments. In the cost-effectiveness analysis, apart from agomelatine, all the treatments were dominated by mirtazapine. Against mirtazapine, agomelatine was not cost effective given that its ICER exceeded the threshold value. CONCLUSION Agomelatine, escitalopram and mirtazapine had favourable balance between efficacy and tolerability. In addition, mirtazapine was a cost-effective option in the Singapore healthcare system.

Abstract
BACKGROUND Major depressive disorder (MDD) has detrimental effects on an individual's personal life, leads to increased risk of comorbidities, and places an enormous economic burden on society. Several 'second-generation' antidepressants are available as both immediate-release (IR) and extended-release formulations. The advantage of extended-release formulations may be the potentially improved adherence and a lower risk of adverse events. OBJECTIVE We conducted a systematic review to assess the comparative efficacy, risk of harms, and patients' adherence of IR and extended-release antidepressants for the treatment of MDD. DATA SOURCE English-language abstracts were retrieved from PubMed, EMBASE, the Cochrane Library, PsycINFO, and International Pharmaceutical Abstracts from 1980 to October 2012, as well as from reference lists of pertinent review articles and grey literature searches. ELIGIBILITY CRITERIA We included head-to-head randomized controlled trials (RCTs) of at least 6 weeks' duration that compared an IR formulation with an extended-release formulation of the same antidepressant in adult patients with MDD. We also included placebo-controlled trials to conduct a network meta-analysis. To assess harms and adherence, in addition to RCTs, we searched for observational studies with ≥1,000 participants and a follow-up of ≥12 weeks. STUDY APPRAISAL AND SYNTHESIS METHODS We dually reviewed abstracts and full texts and assessed quality ratings. Lacking head-to-head evidence for many comparisons of interest, we conducted network meta-analyses using Bayesian methods. Our outcome measure of choice was response on the Hamilton Depression Rating Scale. RESULTS We located seven head-to-head trials and 94 placebo- and active-controlled trials for network meta-analysis. Overall, our analyses indicate that IR and extended-release formulations do not differ substantially with respect to efficacy and risk of harms. The evidence is mixed with respect to differences in adherence, indicating lower adherence for IR formulations. LIMITATIONS The lack of head-to-head comparisons for many drugs compromises our conclusions. Network meta-analyses have methodological limitations that need to be taken into consideration when interpreting findings. CONCLUSION Available evidence currently shows no clear differences between the two formulations and therefore we cannot recommend a first choice. However, if adherence or compliance with one medication is an issue, then clinicians and patients should consider the alternative medication. If adherence or costs are a problem with one formulation, consideration of the other formulation to provide an adequate treatment trial is reasonable.

Comparable efficacy and safety of 8 weeks treatment with agomelatine 25-50mg or fluoxetine 20-40mg in Asian out-patients with major depressive disorder. Asian J Psychiatr 2014; 8:26-32. [PMID: 24655622 DOI: 10.1016/j.ajp.2013.09.009] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2013] [Revised: 09/13/2013] [Accepted: 09/22/2013] [Indexed: 11/24/2022]
Abstract
OBJECTIVE This randomized, double-blind study evaluates the efficacy and tolerability of agomelatine, using fluoxetine as an active comparator, in Asian patients suffering from moderate to severe major depressive disorder (MDD). METHOD Patients were randomly assigned to receive either agomelatine (25-50mg/day, n=314) or fluoxetine (20-40mg/day, n=314) during an 8-week treatment period. The main outcome measure was the change in Hamilton Depression Rating Scale 17 items (HAM-D17) scores. Secondary efficacy criteria included scores on Clinical Global Impression Severity of illness (CGI-S) and Improvement of illness (CGI-I), patient sleeping improvement using the self-rating Leeds Sleep Evaluation Questionnaire (LSEQ) and anxiety using the Hamilton Anxiety Rating Scale (HAM-A) scores. Tolerability and safety evaluations were based on emergent adverse events. RESULTS Agomelatine and fluoxetine exert a comparable antidepressant efficacy in the Asian population. Mean changes over 8 weeks were clinically relevant and similar in both groups (-14.8±7.3 and -15.0±8.1 on HAM-D17 scale in agomelatine and fluoxetine groups, respectively). The between-group difference reached statistical significance on non-inferiority test (p=0.015). Clinically relevant decreases in CGI-S and CGI-I scores were observed over the treatment period in both groups. The two treatments were equally effective on the symptoms of both anxiety and sleep. The good tolerability profile and safety of both doses of agomelatine was confirmed in the Asian population. CONCLUSIONS Agomelatine and fluoxetine are equally effective in the treatment of MDD-associated symptoms in Asian depressed patients.

Abstract
BACKGROUND Depression is common in primary care and is associated with marked personal, social and economic morbidity, thus creating significant demands on service providers. The antidepressant fluoxetine has been studied in many randomised controlled trials (RCTs) in comparison with other conventional and unconventional antidepressants. However, these studies have produced conflicting findings.Other systematic reviews have considered selective serotonin reuptake inhibitor (SSRIs) as a group which limits the applicability of the indings for fluoxetine alone. Therefore, this review intends to provide specific and clinically useful information regarding the effects of fluoxetine for depression compared with tricyclics (TCAs), SSRIs, serotonin-noradrenaline reuptake inhibitors (SNRIs), monoamineoxidase inhibitors (MAOIs) and newer agents, and other conventional and unconventional agents. OBJECTIVES To assess the effects of fluoxetine in comparison with all other antidepressive agents for depression in adult individuals with unipolar major depressive disorder. SEARCH METHODS We searched the Cochrane Collaboration Depression, Anxiety and Neurosis Review Group Controlled Trials Register (CCDANCTR)to 11May 2012. This register includes relevant RCTs from the Cochrane Central Register of Controlled Trials (CENTRAL) (all years),MEDLINE (1950 to date), EMBASE (1974 to date) and PsycINFO (1967 to date). No language restriction was applied. Reference lists of relevant papers and previous systematic reviews were handsearched. The pharmaceutical company marketing fluoxetine and experts in this field were contacted for supplemental data. SELECTION CRITERIA All RCTs comparing fluoxetine with any other AD (including non-conventional agents such as hypericum) for patients with unipolar major depressive disorder (regardless of the diagnostic criteria used) were included. For trials that had a cross-over design only results from the first randomisation period were considered. DATA COLLECTION AND ANALYSIS Data were independently extracted by two review authors using a standard form. Responders to treatment were calculated on an intention-to-treat basis: dropouts were always included in this analysis. When data on dropouts were carried forward and included in the efficacy evaluation, they were analysed according to the primary studies; when dropouts were excluded from any assessment in the primary studies, they were considered as treatment failures. Scores from continuous outcomes were analysed by including patients with a final assessment or with the last observation carried forward. Tolerability data were analysed by calculating the proportion of patients who failed to complete the study due to any causes and due to side effects or inefficacy. For dichotomous data, odds ratios (ORs) were calculated with 95% confidence intervals (CI) using the random-effects model. Continuous data were analysed using standardised mean differences (SMD) with 95% CI. MAIN RESULTS A total of 171 studies were included in the analysis (24,868 participants). The included studies were undertaken between 1984 and 2012. Studies had homogenous characteristics in terms of design, intervention and outcome measures. The assessment of quality with the risk of bias tool revealed that the great majority of them failed to report methodological details, like the method of random sequence generation, the allocation concealment and blinding. Moreover, most of the included studies were sponsored by drug companies, so the potential for overestimation of treatment effect due to sponsorship bias should be considered in interpreting the results. Fluoxetine was as effective as the TCAs when considered as a group both on a dichotomous outcome (reduction of at least 50% on the Hamilton Depression Scale) (OR 0.97, 95% CI 0.77 to 1.22, 24 RCTs, 2124 participants) and a continuous outcome (mean scores at the end of the trial or change score on depression measures) (SMD 0.03, 95% CI -0.07 to 0.14, 50 RCTs, 3393 participants). On a dichotomousoutcome, fluoxetine was less effective than dothiepin or dosulepin (OR 2.13, 95% CI 1.08 to 4.20; number needed to treat (NNT) =6, 95% CI 3 to 50, 2 RCTs, 144 participants), sertraline (OR 1.37, 95% CI 1.08 to 1.74; NNT = 13, 95% CI 7 to 58, 6 RCTs, 1188 participants), mirtazapine (OR 1.46, 95% CI 1.04 to 2.04; NNT = 12, 95% CI 6 to 134, 4 RCTs, 600 participants) and venlafaxine(OR 1.29, 95% CI 1.10 to 1.51; NNT = 11, 95% CI 8 to 16, 12 RCTs, 3387 participants). On a continuous outcome, fluoxetine was more effective than ABT-200 (SMD -1.85, 95% CI -2.25 to -1.45, 1 RCT, 141 participants) and milnacipran (SMD -0.36, 95% CI-0.63 to -0.08, 2 RCTs, 213 participants); conversely, it was less effective than venlafaxine (SMD 0.10, 95% CI 0 to 0.19, 13 RCTs,3097 participants). Fluoxetine was better tolerated than TCAs considered as a group (total dropout OR 0.79, 95% CI 0.65 to 0.96;NNT = 20, 95% CI 13 to 48, 49 RCTs, 4194 participants) and was better tolerated in comparison with individual ADs, in particular amitriptyline (total dropout OR 0.62, 95% CI 0.46 to 0.85; NNT = 13, 95% CI 8 to 39, 18 RCTs, 1089 participants), and among the newer ADs ABT-200 (total dropout OR 0.18, 95% CI 0.08 to 0.39; NNT = 3, 95% CI 2 to 5, 1 RCT, 144 participants), pramipexole(total dropout OR 0.12, 95% CI 0.03 to 0.42, NNT = 3, 95% CI 2 to 5, 1 RCT, 105 participants), and reboxetine (total dropout OR0.60, 95% CI 0.44 to 0.82, NNT = 9, 95% CI 6 to 24, 4 RCTs, 764 participants). AUTHORS' CONCLUSIONS The present study detected differences in terms of efficacy and tolerability between fluoxetine and certain ADs, but the clinical meaning of these differences is uncertain.Moreover, the assessment of quality with the risk of bias tool showed that the great majority of included studies failed to report details on methodological procedures. Of consequence, no definitive implications can be drawn from the studies' results. The better efficacy profile of sertraline and venlafaxine (and possibly other ADs) over fluoxetine may be clinically meaningful,as already suggested by other systematic reviews. In addition to efficacy data, treatment decisions should also be based on considerations of drug toxicity, patient acceptability and cost.

Abstract
BACKGROUND Patients with major depressive disorder (MDD) often suffer from accompanying symptoms that influence the choice of pharmacotherapy with second-generation antidepressants (SGAs). We conducted a systematic review to determine the comparative effectiveness of citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, desvenlafaxine, duloxetine, venlafaxine, bupropion, mirtazapine, nefazodone, and trazodone, for accompanying anxiety, insomnia, and pain in patients with MDD. METHODS We conducted searches in multiple databases including MEDLINE®, Embase, the Cochrane Library, International Pharmaceutical Abstracts, and PsycINFO, from 1980 through August 2011 and reviewed reference lists of pertinent articles. We dually reviewed abstracts, full-text articles, and abstracted data. We included randomized, head-to-head trials of SGAs of at least 6 weeks' duration. We grouped SGAs into three classes for the analysis: selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors, and others. We graded the strength of the evidence as high, moderate, low, or very low based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group (GRADE) approach. RESULTS We located 19 head-to-head trials in total: 11 on anxiety, six on insomnia, and four on pain. For the majority of comparisons, the strength of the evidence was moderate or low: evidence is weakened by inconsistency and imprecision. For treating anxiety, insomnia, and pain moderate evidence suggests that the SSRIs do not differ. CONCLUSIONS Evidence guiding the selection of an SGA based on accompanying symptoms of depression is limited. Very few trials were designed and adequately powered to answer questions about accompanying symptoms; analyses were generally of subgroups in larger MDD trials.

Abstract
Escitalopram (escitalopram oxalate; Cipralex(®), Lexapro(®)) is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of major depressive disorder (MDD) and anxiety disorder. This drug exerts a highly selective, potent, and dose-dependent inhibitory effect on the human serotonin transport. By inhibiting the reuptake of serotonin into presynaptic nerve endings, this drug enhances the activity of serotonin in the central nervous system. Escitalopram also has allosteric activity. Moreover, the possibility of interacting with other drugs is considered low. This review covers randomized, controlled studies that enrolled adult patients with MDD to evaluate the efficacy of escitalopram based on the Montgomery-Asberg Depression Rating Scale and the Hamilton Depression Rating Scale. The results showed that escitalopram was superior to placebo, and nearly equal or superior to other SSRIs (eg, citalopram, paroxetine, fluoxetine, sertraline) and serotonin-noradrenaline reuptake inhibitors (eg, duloxetine, sustained-release venlafaxine). In addition, with long-term administration, escitalopram has shown a preventive effect on MDD relapse and recurrence. Escitalopram also showed favorable tolerability, and associated adverse events were generally mild and temporary. Discontinuation symptoms were milder with escitalopram than with paroxetine. In view of the patient acceptability of escitalopram, based on both a meta-analysis and a pooled analysis, this drug was more favorable than other new antidepressants. The findings indicate that escitalopram achieved high continuity in antidepressant drug therapy.

Abstract
INTRODUCTION Disturbed sleep is a key symptom in major depressive disorder (MDD) and generalized anxiety disorder (GAD). First-line antidepressants, including the selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs), may have different effects on sleep. METHODS Data from 22 randomized, controlled trials comparing escitalopram with SSRIs, SNRIs, or placebo in the treatment of adult MDD or GAD were included. Both last observation carried forward (LOCF) and repeated measurements (MMRM) were used to analyze the sleep item of the Montgomery Åsberg Depression Rating Scale (MADRS) or Hamilton Anxiety Rating Scale (HAM-A) after 8 weeks of treatment. Sleep-related treatment-emergent adverse events were also compared across groups. RESULTS For patients with MDD (n = 5133), the treatment difference on MADRS item 4 ("reduced sleep") was significantly in favor of escitalopram versus placebo (LOCF [P = 0.0017] and MMRM [P = 0.0002]), versus SSRIs (LOCF [P = 0.0020] and MMRM [P < 0.0031]), and versus SNRIs (LOCF [P = 0.0002] and MMRM [P = 0.0352]). For the 53% of patients with MDD who suffered from sleep problems at baseline (baseline MADRS item 4 score ≥ 4), the improvement in sleep symptoms was significantly in favor of escitalopram versus placebo (LOCF [P = 0.0022] and MMRM [P < 0.0005]), versus SSRIs (LOCF [P = 0.0001] and MMRM [P = 0.0002]), and versus SNRIs (LOCF [P < 0.0067] but not MMRM [P > 0.0787]). For patients with GAD (n = 2052) the treatment difference in sleep symptoms measured by HAM-A item 4 ("insomnia") was significantly in favor of escitalopram versus placebo (LOCF [P = 0.0005] and MMRM [P < 0.0001]), but not different to paroxetine or venlafaxine. The same pattern was seen for the large proportion (67%-82%) of GAD patients reporting sleep problems at baseline (baseline HAM-A item 4 score ≥ 2). In MDD, the rate of insomnia as an adverse event after escitalopram was higher than placebo, similar to SSRIs, and lower than SNRIs. CONCLUSIONS Additional research assessing the comparative effects of antidepressants with polysomnography is needed. In the interim, from a clinical perspective, escitalopram appears to be beneficial for the treatment of sleep problems in MDD and GAD.

Abstract
Escitalopram (escitalopram oxalate; Cipralex, Lexapro), a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of major depressive disorder (MDD), demonstrates a highly selective and potent, dose-dependent inhibition of the human serotonin transporter, inhibiting serotonin reuptake into presynaptic nerve terminals and thus increasing serotonergic activity in the CNS. With regard to primary endpoints (such as improved scores on the Montgomery-Asberg Depression Rating Scale [MADRS] and the Hamilton Depression Rating Scale [HAM-D]), escitalopram was generally more effective than placebo, at least as effective as citalopram, and generally at least as effective as other comparator drugs, including the SSRIs fluoxetine, paroxetine and sertraline, the serotonin-noradrenaline (norepinephrine) reuptake inhibitors (SNRIs) venlafaxine extended release and duloxetine, and the aminoketone bupropion in adult patients with MDD in short-term, well designed trials. Moreover, it demonstrated a rapid onset of antidepressant action. Escitalopram was also found to be cost effective in several studies, dominating other SSRIs and venlafaxine extended release. Maintenance therapy is commonly required to prevent recurrence of depression. Long-term trials corroborated short-term results, with escitalopram demonstrating greater efficacy than placebo in relapse prevention. Additionally, escitalopram was at least as effective as citalopram, paroxetine and duloxetine in long-term comparative trials. Escitalopram has a predictable tolerability profile with generally mild to moderate and transient adverse events, and a low propensity for drug interactions. Sexual dysfunction with escitalopram treatment appeared to occur to a similar or lower extent to that with paroxetine (another SSRI), to a similar or greater extent to that with the SNRI duloxetine, and to a greater extent than that with the aminoketone bupropion. Thus, escitalopram is an effective and generally well tolerated treatment for moderate to severe MDD. Escitalopram, like other SSRIs, is an effective first-line option in the management of patients with MDD.

Abstract
The majority of currently marketed drugs contain a mixture of enantiomers; however, recent evidence suggests that individual enantiomers can have pharmacological properties that differ importantly from enantiomer mixtures. Escitalopram, the S-enantiomer of citalopram, displays markedly different pharmacological activity to the R-enantiomer. This review aims to evaluate whether these differences confer any significant clinical advantage for escitalopram over either citalopram or other frequently used antidepressants. Searches were conducted using PubMed and EMBASE (up to January 2009). Abstracts of the retrieved studies were reviewed independently by both authors for inclusion. Only those studies relating to depression or major depressive disorder were included. The search identified over 250 citations, of which 21 studies and 18 pooled or meta-analyses studies were deemed suitable for inclusion. These studies reveal that escitalopram has some efficacy advantage over citalopram and paroxetine, but no consistent advantage over other selective serotonin reuptake inhibitors. Escitalopram has at least comparable efficacy to available serotonin-norepinephrine reuptake inhibitors, venlafaxine XR and duloxetine, and may offer some tolerability advantages over these agents. This review suggests that the mechanistic advantages of escitalopram over citalopram translate into clinical efficacy advantages. Escitalopram may have a favourable benefit-risk ratio compared with citalopram and possibly with several other antidepressant agents.

Abstract
Interest in techniques of noninvasive brain stimulation (NIBS) has been growing exponentially in the last decade. Recent studies have shown that some of these techniques induce significant neurophysiological and clinical effects. Although recent results are promising, there are several techniques that have been abandoned despite positive initial results. In this study, we performed a systematic review to identify NIBS methods with promising preliminary clinical results that were not fully developed and adopted into clinical practice, and discuss its clinical, research and device characteristics. We identified five devices (transmeatal cochlear laser stimulation, transcranial micropolarization, transcranial electrostimulation, cranial electric stimulation and stimulation with weak electromagnetic fields) and compared them with two established NIBS devices (transcranial magnetic stimulation and transcranial direct current stimulation) and with well-known drugs used in neuropsychiatry (pramipexole and escitalopram) in order to understand the reasons why they failed to reach clinical practice and further steps of research development. Finally, we also discuss novel NIBS devices that have recently showed promising results: brain ultrasound and transcranial high-frequency random noise stimulation. Our results show that some of the reasons for the failure of NIBS devices with promising clinical findings are the difficulty to disseminate results, lack of controlled studies, duration of research development, mixed results and lack of standardization.

Abstract
OBJECTIVE To extend the knowledge of course of improvement in patients with major depressive disorder (MDD), social anxiety disorder (SAD) or generalised anxiety disorder (GAD) participating in randomised placebo-controlled trials (RCTs) and to infer the optimal duration of initial escitalopram treatment in clinical practice, after which intervention might be reasonable in case of non-response. METHODS Post hoc analysis of pooled clinical trial database for escitalopram in MDD (14 studies), GAD (4 studies) and SAD (2 studies). 'Onset' of action was defined as a 20% or more decrease from baseline score in disorder-specific psychopathological rating scales: 'response' as a 50% or more decrease from baseline score. RESULTS In MDD, the probability of responding at week 8 if no onset was apparent at week 2 was 43%; in patients with an onset of effect the probability was nearly 80%. Similar patterns were observed in GAD and SAD. The chance of responding beyond week 4 in MDD, GAD and SAD was 20% or less if no effect had occurred by week 2. CONCLUSIONS The pattern of response in these RCTs suggests that in patients with MDD, GAD or SAD in wider clinical practice, a period of at least 4 weeks is worthwhile before considering further intervention.

Abstract
BACKGROUND Although pharmacological and psychological interventions are both effective for major depression, antidepressant drugs remain the mainstay of treatment in primary and secondary care settings. During the last 20 years, antidepressant prescribing has risen dramatically in western countries, mainly because of the increasing consumption of selective serotonin reuptake inhibitors (SSRIs) and newer antidepressants, which have progressively become the most commonly prescribed antidepressants. Escitalopram is the pure S-enantiomer of the racemic citalopram. OBJECTIVES To assess the evidence for the efficacy, acceptability and tolerability of escitalopram in comparison with tricyclics, other SSRIs, heterocyclics and newer agents in the acute-phase treatment of major depression. SEARCH STRATEGY Electronic databases were searched up to July 2008. Trial databases of drug-approving agencies were hand-searched for published, unpublished and ongoing controlled trials. SELECTION CRITERIA All randomised controlled trials comparing escitalopram against any other antidepressant (including non-conventional agents such as hypericum) for patients with major depressive disorder (regardless of the diagnostic criteria used). DATA COLLECTION AND ANALYSIS Data were entered by two review authors (double data entry). Responders and remitters to treatment were calculated on an intention-to-treat basis. For dichotomous data, odds ratios (ORs) were calculated with 95% confidence intervals (CI). Continuous data were analysed using standardised mean differences (with 95% CI) using the random effects model. MAIN RESULTS Fourteen trials compared escitalopram with another SSRI and eight compared escitalopram with a newer antidepressive agent (venlafaxine, bupropion and duloxetine). Escitalopram was shown to be significantly more effective than citalopram in achieving acute response (OR 0.67, 95% CI 0.50 to 0.87). Escitalopram was also more effective than citalopram in terms of remission (OR 0.53, 95% CI 0.30 to 0.93). Significantly fewer patients allocated to escitalopram withdrew from trials compared with patients allocated to duloxetine, for discontinuation due to any cause (OR 0.62, 95% CI 0.38 to 0.99). AUTHORS' CONCLUSIONS Some statistically significant differences favouring escitalopram over other antidepressive agents for the acute phase treatment of major depression were found, in terms of efficacy (citalopram and fluoxetine) and acceptability (duloxetine). There is insufficient evidence to detect a difference between escitalopram and other antidepressants in early response to treatment (after two weeks of treatment). Cost-effectiveness information is also needed in the field of antidepressant trials. Furthermore, as with most standard systematic reviews, the findings rely on evidence from direct comparisons. The potential for overestimation of treatment effect due to sponsorship bias should also be borne in mind.

Abstract
OBJECTIVE To assess the relative antidepressant efficacy of escitalopram and comparator antidepressants. RESEARCH DESIGN AND METHODS A meta-analysis was performed using studies in major depressive disorder (MDD) comparing escitalopram with active controls, including selective serotonin reuptake inhibitors [SSRIs] (citalopram, fluoxetine, paroxetine, sertraline) and serotonin/noradrenaline reuptake inhibitors [SNRIs] (venlafaxine, duloxetine). Adult patients had to meet DSM-IV criteria for MDD. MAIN OUTCOME MEASURES The primary outcome measure was the treatment difference in Montgomery-Asberg Depression Rating Scale (MADRS) total score at week 8. Secondary outcome measures were response and remission (MADRS total score < or = 12) rates. RESULTS Individual patient data (N = 4549) from 16 randomized controlled trials were included in the analyses (escitalopram n = 2272, SSRIs n = 1750, SNRIs n = 527). Escitalopram was significantly more effective than comparators in overall treatment effect, with an estimated mean treatment difference of 1.1 points on the MADRS (p < 0.0001), and in responder (63.7 vs. 58.3%, p < 0.0001) and remitter (53.1 vs. 49.4%, p < 0.0059) analyses. Escitalopram was significantly superior to SSRIs, with an estimated difference in response of 62.1 vs. 58.4% and remission of 51.6 vs. 49.0%. In comparison to SNRIs, the estimated difference in response was 68.3 vs. 59.0% (p = 0.0007) and for remission the difference was 57.8 vs. 50.5% (p = 0.0088). These results were similar for severely depressed patients (baseline MADRS > or = 30). Sensitivity analyses were performed with data from articles reporting Hamilton Rating Scale for Depression (HAMD) scores. The 8-week withdrawal rate due to adverse events was 5.4% for escitalopram and 7.9% for the comparators (p < 0.01). This difference was accounted for by statistically significant higher attrition rates in the SNRI comparisons. This work may be limited by the clinical methodology underlying meta-analytic studies, in particular, the exclusion of trials that fail to meet predetermined criteria for inclusion. CONCLUSIONS In this meta-analysis, superior efficacy of escitalopram compared to SSRIs and SNRIs was confirmed, although the superiority over SSRIs was largely explained by differences between escitalopram and citalopram.
