Abstract
BACKGROUND Primary care patients and clinicians may prefer alternative options to second-generation antidepressants for major depressive disorder (MDD). PURPOSE To compare the benefits and harms of nonpharmacologic treatments with second-generation antidepressants as first-step interventions for acute MDD, and to compare second-step treatment strategies for patients who did not achieve remission after an initial attempt with antidepressants. DATA SOURCES English-language studies from several electronic databases from 1 January 1990 to 8 August 2022, trial registries, gray literature databases, and reference lists to identify unpublished research. STUDY SELECTION 2 investigators independently selected randomized trials of at least 6 weeks' duration. DATA EXTRACTION Reviewers abstracted data about study design and conduct, participants, interventions, and outcomes. They dually rated the risk of bias of studies and the certainty of evidence for outcomes of interest. DATA SYNTHESIS 65 randomized trials met the inclusion criteria; eligible data from nonrandomized studies were not found. Meta-analyses and network meta-analyses indicated similar benefits of most nonpharmacologic treatments and antidepressants as first-step treatments. Antidepressants had higher risks for discontinuation because of adverse events than most other treatments. For second-step therapies, different switching and augmentation strategies provided similar symptomatic relief. The certainty of evidence for most comparisons is low; findings should be interpreted cautiously. LIMITATIONS Many studies had methodological limitations or dosing inequalities; publication bias might have affected some comparisons. In some cases, conclusions could not be drawn because of insufficient evidence. CONCLUSION Although benefits seem to be similar among first- and second-step MDD treatments, the certainty of evidence is low for most comparisons. Clinicians and patients should focus on options with the most reliable evidence and take adverse event profiles and patient preferences into consideration.

Advantages and Disadvantages of Using St. John's Wort as a Treatment for Depression. Cureus 2022; 14:e29468. [PMID: 36299970 PMCID: PMC9587902 DOI: 10.7759/cureus.29468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/22/2022] [Indexed: 11/11/2022] Open
Abstract
Background and objectives: St. John's wort (SJW) extracts are currently being used to treat depression of various degrees of severity. While many studies have shown it to be superior to placebo, data regarding the effectiveness of using SJW as a stand-alone treatment compared with standard antidepressants has yet to be proven conclusively. This study aims to understand the advantages and disadvantages of SJW as a treatment modality for depression. Methods: The authors searched PubMed, JAMA network, Springer Link, Elsevier, Google Scholar, and Scientific Progress databases, from 2011 through August 2021, using the following keywords: St John’s wort, Hypericum perforatum, depression, antidepressant, complementary alternative medicine, economic evaluation depression St. wort, St John’s wort and depression, antidepressant interactions. This yielded a total of 27 papers following a thorough removal of irrelevant content and dissemination in languages other than English. Results: In patients with mild and moderate depression, SJW proved superior to placebo. Certain studies comparing the efficacy of SJW versus selective serotonin reuptake inhibitors (SSRIs), especially fluoxetine, reported SJW to be more efficacious, while the majority reported no significant difference. Tricyclic antidepressants were also found to have similar efficacy as SJW. Moreover, treatment with SJW was also found to reduce postmenopausal depression. Regarding the safety profile, although SJW is better tolerated with fewer adverse effects when compared to standardized antidepressants, its predisposition to causing fatal serotonin syndrome, when used in conjunction with other serotonergic agents and drug interactions noted with CYP 450 drugs, raises a question in the safety profile. Conclusion: It is essential to acknowledge that SJW has been used as a treatment measure in Germany. Despite being only listed as a dietary supplement by the FDA and not a drug, SJW has shown to be comparable, if not more efficacious, than most standard treatment options for depression. SJW does prove to be an exciting piece of pharmacotherapy in the realm of mental health and post-menopausal treatment. More prospective studies will help us better understand its efficacy in mild and moderate depression and its ability to serve as a long-term agent. Considering its mechanism of action, its role in relieving patients suffering from an anxiety disorder is also worth considering.

Abstract
St. John's wort (Hypericum perforatum) is a herbaceous plant containing many bioactive molecules including naphthodianthrones, phloroglucinol derivatives, flavonoids, bioflavonoids, proanthocyanidins, and chlorogenic acid. Evidence has shown the therapeutic effects of St. John's wort and especially its two major active components, hyperforin and hypericin, on different psychiatric and mood disorders such as posttraumatic stress disorder (PTSD), attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), and anxiety disorders. St. John's wort also induces antidepressant effects. In this review study, we aimed to discuss the role of St. John's wort in modulating depression, with respect to the role of different neurotransmitter systems in the brain. We discussed changes in the neurotransmitter levels in depression, and following use of St. John's wort. It was concluded that changes in the function and level of neurotransmitters in depression are complex. Also, St. John's wort can induce inconsistent effects on neurotransmitter levels. We also found that glutamate and acetylcholine may be the most important neurotransmitters to study in future works, because the function of both neurotransmitters in depression is unclear. In addition, St. John's wort induces a dualistic modulation on the activity of cholinergic signaling, which can be an interesting topic for future studies.

Efficacy of the Complementary and Alternative Therapies for the Management of Psychological Symptoms of Menopause: A Systematic Review of Randomized Controlled Trials. J Menopausal Med 2022; 27:115-131.

Abstract
Menopause is not a high-risk period for psychiatric illness but can cause psychological issues; the most common of which are anxiety and depression, which can impair coping and reduce women’s quality of life. Thus, many women have leaned toward complementary and alternative medicine (CAM) for the relief of menopause-related symptoms. No rigorous study exists in the literature on the effects of CAMs on the psychological symptoms of menopause despite this growing patient interest. This systematic review aimed to assess the efficacy of CAM interventions on psychological symptoms of menopause. Databases (PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar) were searched from January 2000 to May 2021 using the keywords: menopause, menopausal symptoms, psychological symptoms, and complementary and alternative medicine. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool (MMAT) for randomized clinical trials. Of the 704 articles found, 33 articles with 3,092 participants entered the final review. Aromatherapy, massage, yoga, and acupuncture, as well as some dietary and herbal supplements improved psychological symptoms during menopause based on the findings of the current study. However, the effectiveness of reflexology and exercise was debatable. However, necessary precautions should be taken when using them in clinical settings despite the positive effect of various CAM interventions on reducing psychological symptoms. More studies with a higher methodology quality are required to make better decisions about the effect of various CAM interventions on the psychological symptoms of menopause.

Abstract
The first clinically relevant reports of preparations of St. John's wort (SJW), a herbal medicine with anti‐depressant effects, interacting with other drugs, altering their bioavailability and efficacy, were published about 20 years ago. In 2000, a pharmacokinetic interaction between SJW and cyclosporine caused acute rejection in two heart transplant patients. Since then, subsequent research has shown that SJW altered the pharmacokinetics of drugs such as digoxin, tacrolimus, indinavir, warfarin, alprazolam, simvastatin, or oral contraceptives. These interactions were caused by pregnane‐X‐receptor (PXR) activation. Preparations of SJW are potent activators of PXR and hence inducers of cytochrome P450 enzymes (most importantly CYP3A4) and P‐glycoprotein. The degree of CYP3A4 induction correlates significantly with the hyperforin content in the preparation. Twenty years after the first occurrence of clinically relevant pharmacokinetic drug interactions with SJW, this review revisits the current knowledge of the mechanisms of action and on how pharmacokinetic drug interactions with SJW could be avoided.

Abstract
Hypericum japonicum Thunb. ex Murray is traditionally used in Nepal to treat several diseases, among whom inflammation and acute pain. Although several secondary metabolites from the same Hypericum species have been already characterized and considered for their pharmacological use, an exhaustive phytochemical characterization of H. japonicum from Nepal is lacking, as well as the assessment of its potential pharmacological properties. Hence, the aims of this study were the characterization of a methanolic extract of H. japonicum (HJME) collected from the Northern region of Nepal by LC-MSn and UPLC-QTOF. The assessment of in vitro inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and activator protein 1 (AP-1) transcription factors and HJME's cytotoxic effect on human cell lines was performed to evaluate the potential use of this herb as a source of anti-inflammatory and cytotoxic lead compounds. Fifty-seven phytoconstituents were identified, being mainly flavonoids, phloroglucinols, phenolic acids and xanthones. Although compounds characteristic of H. japonicum were detected (quercetin, quercetin-7-O-α-l-rhamnoside, quercitrin and hyperoside), several others are here reported for the first time in this species. The results from bioassays indicated that HJME could significantly reduce the viability of human THP-1 cells (IC50 = 5.4 ± 1.1 μg mL-1), showing the promising potential of HJME as anti-tumor agent. Furthermore, HJME significantly decreased the activation of both NF-κB and AP-1 at the concentration of 2 μg mL-1. Overall, these data suggest that H. japonicum from Nepal could be used as a source of potential natural anti-inflammatory and anti-tumor lead compounds.

Abstract
Minor/subthreshold depression is associated with functional impairment, reduced quality of life, and the risk of developing into major depression. Therefore, it should be treated. Watchful waiting should be an option only for patients who, despite adequate information, are not interested in any kind of treatment. Psychotherapy has been found to be effective, but due to methodological problems (control group, blinding), efficacy derived from randomized trials might be over-estimated. Studies on the efficacy of antidepressants in the treatment of minor depression have found clinically relevant benefits over placebo, particularly the newer, better-controlled trials. One major advantage of antidepressants over psychotherapy is their immediate availability and the short period required to evaluate efficacy. Aside from the severity of depression, the patient's attitude towards psychotherapy or antidepressant treatment is of major relevance and should be explored. In a shared decision-making process, the patient should receive appropriate information on treatment options, state her or his preferences, and then receive the treatment of choice.

Abstract
This study aims to carry out a narrative review, aiming to update the literature on subsyndromic depression (SD), which is the most prevalent depressive disorder in older adults, and no formal guidelines or consensus are dedicated to this topic. We carried out an electronic search for articles on SD. Relevant articles were retrieved from Pubmed, EMBASE and Web of Science using the search terms "subthreshold depression," "prevalence," "treatment" and "older adults" in several combinations. Original articles in English were included from inception to 1st March 2019. No clear consensus exists in the literature on its nosologic classification, diagnostic tools, causes, course, outcomes or management. SD diagnosis should base in depressive symptoms scales and DSM criteria. Treatment relies mainly on collaborative care and psychotherapy. SD is relevant in clinical practice and research in geriatric psychiatry. Given the negative outcomes and potential benefits of treatment, we recommend brief psychotherapy as first-line treatment and use of psychotropic agents in cases with greater severity and/or functional impairment in association with psychotherapy. SD can precede major depressive disorder, but it also may consist of a primary depressive disorder in older adults. Furthermore, adequate treatment of SD can prevent or reduce negative outcomes associated with depressive symptoms such as worsening of clinical comorbidities, loss of functionality, increased demand for health services, and increased mortality.

Abstract
BACKGROUND Psychiatric disorders are substantially associated with reduced quality of life and increased mortality. Depression and anxiety are two of the most common psychiatric disorders that often co-occur with each other as well as with other mental health conditions. Because of the limitations of currently available antidepressant therapies, there is a need for agents with improved efficacy and less adverse effects. Hypericum perforatum, widely known as St. John's wort, is a perennial herbaceous plant most well known for its antidepressant properties. METHODS We reviewed the available in vitro, in vivo, and clinical evidence on the efficacy, safety, and mechanisms of action of St. John's wort and its active constituents in the treatment of psychiatric and neurodegenerative disorders. RESULTS Several interesting data have been reported about the antidepressant properties of H. perforatum in clinical trials with different designs. In particular, a number of antidepressant-controlled trials demonstrated that H. perforatum and its active ingredients, hypericin and hyperforin, possess antidepressant properties similar to those of tricyclic antidepressants and selective serotonin reuptake inhibitors but with fewer and milder side effects. CONCLUSION St. John's wort may exert potent antidepressant effects and represents an efficacious and safe treatment. However, the current clinical evidence regarding the efficacy of H. perforatum in other psychiatric and neurodegenerative disorders is not sufficient to draw a robust conclusion.

Abstract
INTRODUCTION St John's wort is a popular herbal remedy recommended by Traditional Chinese Medicine (TCM) practitioners and licensed and widely prescribed for depression in many European countries. However, conflicting data regarding its benefits and risks exist, and the last large meta-analysis on St John's wort use for depression was done in 2008, with no updated meta-analysis available. METHODS Using the keywords [St John's Wort OR Hypericum perforatum OR hypericin OR hyperforin OR johanniskraut OR] AND [depression OR antidepressant OR SSRI], a preliminary search (without language restriction) on the PubMed, Ovid, Clinical Trials Register of the Cochrane Collaboration Depression, Anxiety and Neurosis Group, Cochrane Field for Complementary Medicine, China National Knowledge Infrastructure and WanFang database yielded 5428 papers between 1-Jan-1960 and 1-May-2016. RESULTS 27 clinical trials with a total of 3808 patients were reviewed, comparing the use of St John's wort and SSRI. In patients with depression, St John's wort demonstrated comparable response (pooled RR 0.983, 95% CI 0.924-1.042, p<0.001) and remission (pooled RR 1.013, 95% CI 0.892-1.134, p<0.001) rate, and significantly lower discontinuation/dropout (pooled OR 0.587, 95% CI 0.478-0.697, p<0.001) rate compared to standard SSRIs. The pooled SMD from baseline HAM-D scores (pooled SMD -0.068, 95% CI -0.127 to 0.021, p<0.001) also support its significant clinical efficacy in ameliorating depressive symptoms. LIMITATIONS Evidence on the long-term efficacy and safety of St. John's wort is limited as the duration of all available studies ranged from 4 to 12 weeks. It is also unclear if St John's wort would be beneficial for patients with severe depression, high suicidality or suicide risk. CONCLUSION For patients with mild-to-moderate depression, St John's wort has comparable efficacy and safety when compared to SSRIs. Follow-up studies carried out over a longer duration should be planned to ascertain its benefits.

The objectives of this review are to (1) evaluate the efficacy and safety of SJW in adults with MDD compared to placebo and active comparator and (2) evaluate whether the effects vary by severity of MDD. METHODS We searched PubMed, CINAHL, PsycINFO, CENTRAL, Embase, AMED, MANTIS, Web of Science, and ICTRP and existing reviews to November 2014. Two independent reviewers screened the citations, abstracted the data, and assessed the risk of bias. We included randomized controlled trials (RCTs) examining the effect of at least a 4-week administration of SJW on depression outcomes against placebo or active comparator in adults with MDD. Risk of bias was assessed using the Cochrane Risk of Bias tool and USPSTF criteria. Quality of evidence (QoE) was assessed using the GRADE approach. RESULTS Thirty-five studies examining 6993 patients met inclusion criteria; eight studies evaluated a hypericum extract that combined 0.3 % hypericin and 1-4 % hyperforin. The herb SJW was associated with more treatment responders than placebo (relative risk [RR] 1.53; 95 % confidence interval [CI] 1.19, 1.97; I(2) 79 %; 18 RCTs; N = 2922, moderate QoE; standardized mean differences [SMD] 0.49; CI 0.23, 0.74; 16 RCTs; I(2) 89 %, N = 2888, moderate QoE). Compared to antidepressants, SJW participants were less likely to experience adverse events (OR 0.67; CI 0.56, 0.81; 11 RCTs; moderate QoE) with no difference in treatment effectiveness (RR 1.01; CI 0.90, 1.14; 17 RCTs, I(2) 52 %, moderate QoE; SMD -0.03; CI -0.21, 0.15; 14 RCTs; I(2) 74 %; N = 2248, moderate QoE) in mild and moderate depression. CONCLUSIONS SJW monotherapy for mild and moderate depression is superior to placebo in improving depression symptoms and not significantly different from antidepressant medication. However, evidence of heterogeneity and a lack of research on severe depression reduce the quality of the evidence. Adverse events reported in RCTs were comparable to placebo and fewer compared with antidepressants. However, assessments were limited due to poor reporting of adverse events and studies were not designed to assess rare events. Consequently, the findings should be interpreted with caution.

Abstract
OBJECTIVE The aim of the study was to investigate the efficacy and safety of St John's wort extract and selective serotonin reuptake inhibitors (SSRIs) in the treatment of depression. METHODS Databases were searched for studies comparing efficacy and/or safety of St John's wort extract with SSRIs in depression from 1966 to April 2015. Stata software was used for statistical analysis. RESULTS Twenty-seven studies met the study entry criteria. A total of 3,126 patients with depression were included. St John's wort extract did not differ from SSRIs in clinical response, remission, and mean reduction in Hamilton Rating Scale for Depression score. St John's wort extract had a significantly lower rate of adverse events compared to SSRIs (summary relative risk: 0.77; 95% confidence interval: 0.70, 0.84, P=0.00) and had fewer withdrawals due to adverse events. St John's wort extract had superior safety in the management of patients with depression. CONCLUSION Both St John's wort extract and SSRIs are effective in treating mild-to-moderate depression. St John's wort extract is safer than SSRIs.

Abstract
Hypericum perforatum is a perennial plant, with worldwide distribution, commonly known as St. John's wort. It has been used for centuries in traditional medicine for the treatment of several disorders, such as minor burns, anxiety, and mild to moderate depression. In the past years, its antidepressant properties have been extensively studied. Despite that, other H. perforatum biological activities, as its neuroprotective properties have also been evaluated. The present review aims to provide a comprehensive summary of the main biologically active compounds of H. perforatum, as for its chemistry, pharmacological activities, drug interactions and adverse reactions and gather scattered information about its neuroprotective abilities. As for this, it has been demonstrated that H. perforatum extracts and several of its major molecular components have the ability to protect against toxic insults, either directly, through neuroprotective mechanisms, or indirectly, through is antioxidant properties. H. perforatum has therefore the potential to become an effective neuroprotective therapeutic agent, despite further studies that need to be carried out.

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
The present study was taken up to investigate the effect of petroleum ether extract of Tinospora cordifolia (Wild.) Miers, on depression in mice. The extract (50, 100 and 200 mg/kg, p.o.) was administered for 14 successive days to Swiss young albino mice (either sex) and evaluated for antidepressant-like activity using tail suspension test and forced swim test. Petroleum ether extract at all three doses produced significant antidepressant-like effect in tail suspension test as well as in forced swim test and their efficacies were found to be comparable to imipramine (15 mg/kg, p.o.) and sertraline (20 mg/kg, p.o.). The extract at a dose of 50 mg/kg showed most potent effect and did not show any significant change in locomotor functions of mice as compared to control. The antidepressant-like effect of the extract was significantly reversed by pretreatment of animals with prazosin (a α1-adrenoceptor antagonist), sulpiride (a selective dopamine D2-receptor antagonist), p-CPA (a serotonin synthesis inhibitor) and baclofen (GABA-B agonist), when tested in tail suspension test. Moreover, petroleum ether extract also reduced the mouse whole brain monoamine oxidase (MAO-A and MAO-B) activities as compared to control, resulting in increase in the levels of brain monoamines. Therefore, the extract may have potential therapeutic value for the management of depressive disorders.

Abstract
AIMS In this study, antidepressant-like activity of Emblica offcinalis Gaertn. fruits (Family: Euphorbiaceae) was evaluated in Swiss young male albino mice employing tail suspension test and forced swim test. METHODS Aqueous extract (200 and 400 mg/kg) of the fruits was administered orally for 14 successive days to mice. On day 14, 60 min after extract administration, animals were subjected to tail suspension test and forced swim test. RESULTS The extract significantly decreased immobility period in both tail suspension test and forced swim test, indicating significant antidepressant-like activity. The lower dose (200 mg/kg) of the extract showed better antidepressant-like action. The efficacy of the extract was found to be comparable to fluoxetine (20 mg/kg), imipramine (15 mg/kg), and phenelzine (20 mg/kg). The extract did not show any significant effect on locomotor activity of the mice. Prazosin (alpha(1) -adrenoceptor antagonist), sulpiride (selective D(2) -receptor antagonist), baclofen (GABA(B) agonist), and p-CPA (tryptophan hydroxylase inhibitor) significantly attenuated the extract-induced antidepressant-like effect. The extract also significantly decreased brain MAO-A levels. DISCUSSION The aqueous extract might produce antidepressant-like effect by interaction with α(1)-adrenoceptors, dopamine D(2)- receptors, serotonergic, and GABA(B) receptors. In this study, aqueous extract was found to contain 2.94% of ascorbic acid. So ascorbic acid and other constituents like flavanoids, tannoid principles, and polyphenolic substances present in the aqueous extract of E. officinalis might be responsible for its antidepressant-like activity. CONCLUSIONS Thus, aqueous extract of E. officinalis showed antidepressant-like activity probably by inhibiting MAO-A and GABA; and also due to its antioxidant activity.

Abstract
The burden of rising health care expenditures has created a demand for information regarding the clinical and economic outcomes associated with complementary and alternative medicines. Meta-analyses of randomized controlled trials have found Hypericum perforatum preparations to be superior to placebo and similarly effective as standard antidepressants in the acute treatment of mild to moderate depression. A clear advantage over antidepressants has been demonstrated in terms of the reduced frequency of adverse effects and lower treatment withdrawal rates, low rates of side effects and good compliance, key variables affecting the cost-effectiveness of a given form of therapy. The most important risk associated with use is potential interactions with other drugs, but this may be mitigated by using extracts with low hyperforin content. As the indirect costs of depression are greater than five times direct treatment costs, given the rising cost of pharmaceutical antidepressants, the comparatively low cost of Hypericum perforatum extract makes it worthy of consideration in the economic evaluation of mild to moderate depression treatments.

Abstract
Selective serotonin reuptake inhibitors (SSRIs) like paroxetine have replaced older antidepressants mainly because of a more favorable safety profile, but they are still associated with burdensome side effects. We investigate the tolerability of St. John's wort extract WS 5570, a herbal antidepressant with proven efficacy, in comparison to paroxetine and other SSRIs and placebo. A reanalysis was performed based on the original data from four controlled clinical trials during which 1661 outpatients with major depression (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition criteria) received between 600 and 1800 mg/day WS 5570 (n=1264), 20 or 40 mg/day paroxetine (n=126), or placebo (n=271) for 6 weeks. For single and grouped adverse events, the risk ratios for treatment group comparisons were determined along with their 95% confidence intervals, including comparisons with published data for SSRIs. Across the four trials, the percentage of patients with any adverse events under WS 5570 exposition was comparable with placebo [risk ratio (95% confidence interval): 1.1 (0.9-1.3) in favor of WS 5570] and significantly lower than for paroxetine [2.4 (2.1-2.8)]. Compared with the herbal extract adverse event rates under paroxetine were between 10 and 38-fold higher (point estimates) in five out of seven symptom clusters inspected. WS 5570 was devoid of effects of sedation, anticholinergic reactions, gastrointestinal disturbances, and sexual dysfunction often found during treatment with SSRIs and other synthetic antidepressants. In conclusion, WS 5570 exhibits substantially lower incidence rates of adverse events than paroxetine and other SSRIs.

Abstract
Hyperici herba (Hyp) is the aerial part collected during the flowering period from the well-known herb, Hypericum perforatum. Black lipid membrane experiments were performed to investigate the effect of the ethanolic Hyp extract on the electrical properties (capacitance and conductance) of artificial lipid bilayers. Hyp extract (1–10 μg mL−1) induced a concentration-dependent increase of both specific transmembrane capacitance and conductance in phosphatidylcholine (PC) membranes. The effect on conductance was enhanced when the Hyp extract (3 μg mL−1) was present on both sides of the membrane (Gm = 77.89 ± 8.81 nS cm−2, n = 5) compared with single-sided application (Gm = 36.48 ± 2.41 nS cm−2, n = 5). In bilayers containing PC and phosphatidylserine (PS), PC:PS, the Hyp extract effect was greater than on pure PC bilayers, although the surface charge was not the determining factor of this enhanced activity. Adding cholesterol to the PC:PS mixture reverted the conductance increase induced by the Hyp extract in a dose-dependent manner. The specific pattern of the Hyp extract interaction with lipid bilayers has possible consequences concerning its absorption and bioavailability, as well as its pharmacodynamic effects on neuronal excitability.

Abstract
The popularity of natural or "alternative" remedies to treat medical and psychiatric disorders has accelerated dramatically over the past decade, in the United States and worldwide. This article reviews the evidence for clinical efficacy, active ingredients, mechanisms of action, recommended dosages, and toxicities of the 3 best-studied putative natural antidepressants, St. John's wort (hypericum), S-adenosyl methionine, and the Omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid. Despite growing evidence for efficacy and safety, more comprehensive studies are required before these remedies can be recommended as safe and effective alternatives or adjuncts to conventional psychotropic agents. There are limited data regarding safety in pregnancy and during lactation, and caution is therefore recommended in women who are pregnant or breastfeeding.

Abstract
BACKGROUND Mood and anxiety disorders pose significant health burdens on the community. Kava and St. John's wort (SJW) are the most commonly used herbal medicines in the treatment of anxiety and depressive disorders, respectively. OBJECTIVES The objective of this study was to conduct a comprehensive review of kava and SJW, to review any evidence of efficacy, mode of action, pharmacokinetics, safety and use in major depressive disorder, bipolar disorder, seasonal affective disorder (SAD), generalized anxiety disorder, social phobia (SP), panic disorder (PD), obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD). METHODS A systematic review was conducted using the electronic databases MEDLINE, CINAHL, and The Cochrane Library during late 2008. The search criteria involved mood and anxiety disorder search terms in combination with kava, Piper methysticum, kavalactones, St. John's wort, Hypericum perforatum, hypericin, and hyperforin. Additional search criteria for safety, pharmacodynamics, and pharmacokinetics were employed. A subsequent forward search was conducted of the papers using Web of Science cited reference search. RESULTS Current evidence supports the use of SJW in treating mild-moderate depression, and for kava in treatment of generalized anxiety. In respect to the other disorders, only weak preliminary evidence exists for use of SJW in SAD. Currently there is no published human trial on use of kava in affective disorders, or in OCD, PTSD, PD, or SP. These disorders constitute potential applications that warrant exploration. CONCLUSIONS Current evidence for herbal medicines in the treatment of depression and anxiety only supports the use of Hypericum perforatum for depression, and Piper methysticum for generalized anxiety.

Abstract
Hypericum perforatum is a medicinal plant with established antidepressant properties. The aim of this meta-analysis was to compare the efficacy and tolerability of this antidepressant with selective serotonin reuptake inhibitors (SSRIs) as a group of standard antidepressants. For this purpose, Pubmed, Embase, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials were searched for studies comparing efficacy and/or tolerability of Hypericum with SSRIs in the management of major depressive disorder (MDD). The search terms were: "Hypericum" or "St. John's wort" and "fluoxetine", "paroxetine", "citalopram", "serteraline", "escitalopram", or "fluvoxamine". Data were collected from 1966 to 2008 (up to June). "Clinical response", "remission", "mean reduction in Hamilton Rating Scale for Depression (HAMD) score from baseline", "total adverse events", and "withdrawals due to adverse events" were the key outcomes of interest. Thirteen randomized placebo controlled clinical trials met our criteria and were included. Comparison of SSRIs with placebo yielded a significant relative risk (RR) of 1.22 (95% confidence interval: 1.03-1.45, P=0.02) for clinical response (n=4), a non significant RR of 0.96 (95% CI: 0.71-1.29, P=0.76) for remission (n=4), and a significant effect size [weighted mean difference (wmd+)] of 1.33 (95% CI: 1.15-1.51, P<0.0001) for mean reduction in HAMD score from baseline (n=3). Comparison of Hypericum with SSRIs yielded a non significant relative risk (RR) of 0.99 (95% confidence interval: 0.91-1.08, P=0.83) for clinical response, a non significant RR of 1.1 (95% CI: 0.90-1.35, P=0.35) for remission, and a non-significant wmd+ of 0.32 (95% CI: -1.28-0.64, P=0.52) for mean reduction in HAMD score from baseline, a non significant RR of 0.85 (95% CI: 0.7-1.04, P=0.11) for any adverse events, and a significant RR of 0.53 (95% CI: 0.35-0.82, P=0.004) for withdrawals due to adverse events. Hypericum does not differ from SSRIs according to efficacy and adverse events in MDD. Lower withdrawal from study due to adverse events by Hypericum is an advantage in management of MDD.

Abstract
BACKGROUND In some countries extracts of the plant Hypericum perforatum L. (popularly called St. John's wort) are widely used for treating patients with depressive symptoms. OBJECTIVES To investigate whether extracts of hypericum are more effective than placebo and as effective as standard antidepressants in the treatment of major depression; and whether they have fewer adverse effects than standard antidepressant drugs. SEARCH STRATEGY Trials were searched in computerised databases, by checking bibliographies of relevant articles, and by contacting manufacturers and researchers. SELECTION CRITERIA Trials were included if they: (1) were randomised and double-blind; (2) included patients with major depression; (3) compared extracts of St. John's wort with placebo or standard antidepressants; (4) included clinical outcomes assessing depressive symptoms. DATA COLLECTION AND ANALYSIS At least two independent reviewers extracted information from study reports. The main outcome measure for assessing effectiveness was the responder rate ratio (the relative risk of having a response to treatment). The main outcome measure for adverse effects was the number of patients dropping out due to adverse effects. MAIN RESULTS A total of 29 trials (5489 patients) including 18 comparisons with placebo and 17 comparisons with synthetic standard antidepressants met the inclusion criteria. Results of placebo-controlled trials showed marked heterogeneity. In nine larger trials the combined response rate ratio (RR) for hypericum extracts compared with placebo was 1.28 (95% confidence interval (CI), 1.10 to 1.49) and from nine smaller trials was 1.87 (95% CI, 1.22 to 2.87). Results of trials comparing hypericum extracts and standard antidepressants were statistically homogeneous. Compared with tri- or tetracyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs), respectively, RRs were 1.02 (95% CI, 0.90 to 1.15; 5 trials) and 1.00 (95% CI, 0.90 to 1.11; 12 trials). Both in placebo-controlled trials and in comparisons with standard antidepressants, trials from German-speaking countries reported findings more favourable to hypericum. Patients given hypericum extracts dropped out of trials due to adverse effects less frequently than those given older antidepressants (odds ratio (OR) 0.24; 95% CI, 0.13 to 0.46) or SSRIs (OR 0.53, 95% CI, 0.34-0.83). AUTHORS' CONCLUSIONS The available evidence suggests that the hypericum extracts tested in the included trials a) are superior to placebo in patients with major depression; b) are similarly effective as standard antidepressants; c) and have fewer side effects than standard antidepressants. The association of country of origin and precision with effects sizes complicates the interpretation.

Abstract
OBJECTIVE This paper reviews the commonly used botanicals for treatment of mood and anxiety disorders in perimenopausal and postmenopausal women and presents information on their safety and efficacy. DESIGN The MEDLINE and EMBASE databases were searched for clinical trials related to the use of botanicals for depression, anxiety, and mood disturbances. Papers were excluded if they were in a language other than English, did not include midlife women as study participants, or did not report on changes in mood, depression, or anxiety. RESULTS Five of seven trials of St. John's wort for mild to moderate depression showed a significant improvement. The one randomized, controlled trial of ginseng in postmenopausal women reported improvements in mood and anxiety. All three randomized, controlled trials of ginkgo found no effect on depression. In four of eight controlled trials, kava significantly reduced anxiety. Black cohosh significantly reduced depression and anxiety in all studies reviewed. CONCLUSIONS St. John's wort and black cohosh appear to be the most useful in alleviating mood and anxiety changes during menopause. Ginseng may be effective, but more research needs to be done. Kava holds promise for decreasing anxiety in peri- and postmenopausal women; however, women should be careful in the amount and duration of use. Finally, ginkgo and valerian do not appear to be useful in reducing depression or anxiety in this population.

Abstract
This paper reports a critical review of 27 herbal medicines and formulas in treating a broad range of psychiatric disorders (in addition to anxiety and depression), including obsessive-compulsive, seasonal affective, bipolar depressive, psychotic, phobic and somatoform disorders. Ovid Medline, Pubmed and the Cochrane Library were searched for pharmacological and clinical evidence of herbal medicines with psychotropic activity. A forward search of later citations was also conducted. Whilst substantial high-quality evidence exists for the use of kava and St John's wort in the treatment of anxiety and depression respectively, currently there is insufficient robust clinical evidence for the use of many other herbal medicines in psychiatric disorders. Phytotherapies which potentially have significant use in psychiatry, and urgently require more research are Rhodiola rosea (roseroot) and Crocus sativus (saffron) for depression; Passiflora incarnata (passionflower), Scutellaria lateriflora (scullcap) and Zizyphus jujuba (sour date) for anxiety disorders; and Piper methysticum (kava) for phobic, panic and obsessive-compulsive disorders. While depression and anxiety are commonly researched, the efficacy of herbal medicines in other mental disorders requires attention. The review addresses current issues in herbal psychotherapy: herbal safety, future areas of application, the relationship of herbal medicine with pharmaceuticals and the potential prescriptive integration of phytomedicines with synthetic psychotropic medicines. Particular attention is given to clinical and safety issues with St John's wort and kava.

Abstract
Natural medications such as St. John's Wort, SAMe, and omega-3 fatty acids eventually may prove to be valuable additions to the psychiatrist's pharmacologic armamentarium, both as monotherapy and as adjunctive therapy for mood disorders. Current research data are compelling, from a standpoint of both efficacy and safety, but before clinicians can recommend these as first-line treatments, more well-designed controlled studies in large patient populations are needed. During the past decade, the National Institutes of Health, the National Institute for Mental Health, and the National Center for Complementary and Alternative Medicine have widened their support for research on the efficacy and safety of alternative treatments, and increasing numbers of academic institutions are undertaking large-scale, multicenter studies on the natural medications reviewed here, as well as others. These studies should help answer some of the yet-unsettled questions about natural medications. Psychiatrists who are considering recommending natural antidepressants to their patients should emphasize that these treatments are relatively unproven and that it remains to be seen whether they would be appropriate or preferable to the conventional psychotropic agents. in the absence of more conclusive data, the best candidates for alternative treatments may be patients for whom a delay in adequate treatment would not be devastating(eg, the mildly symptomatic patient who has a strong interest in natural remedies). Other good candidates may include patients who have been unresponsive to conventional antidepressants or particularly intolerant of side effects; these patients, however, often are the most difficult to treat, and alternative agents seem best suited for the mildly ill. Care should be taken with patients who are taking multiple medications, in view of adverse drug-drug interactions that have emerged with increased use of alternative treatments. Finally, as with all psychotropic agents, natural medications should be used preferably under the supervision of a physician.

Abstract
During the past 10 years our knowledge about the pharmacotherapy of depression has been consolidated, and a variety of very interesting new compounds launched onto the market. The pipeline of the pharmaceutical industry is still filled with an assortment of new developments and very promising new approaches towards the pharmacotherapy of depressive disorders. Future pharmacological treatments of depression will not only enhance serotonergic and noradrenergic neurotransmission: other systems, such as the melatonergic receptor system and the hypothalamus-pituitary-adrenal axis, are also the targets of newly developed and upcoming substances with putative antidepressant effects. The main advantages of the currently available newer pharmacotherapeutic options are the broadening of the spectrum of possible antidepressant treatments, which is of particular importance for the growing number of patients suffering from difficult-to-treat depression, and a far better tolerability profile in comparison to older compounds such as tricyclic antidepressants. Unresolved issues are the unacceptably high rate of non-responsiveness during antidepressant treatment, a latency of sometimes several weeks until clinical improvement and remission can be achieved, and a variety of possible side effects also present during treatment with modern compounds. This review mainly presents the development of antidepressant pharmacotherapies during the past 10 years, together with pharmacokinetic and pharmacodynamic information and a comparison of different pharmacological treatment principles evaluated in randomized controlled clinical trials. In addition, new pharmacological strategies that are not yet available on the market and strategies currently under development are reviewed in detail. The study of new treatment options is of major importance to provide better strategies for the clinical management of depression in the future, and is thus also of great socio-economic importance.

Abstract
A systematic review of randomized controlled trials was conducted to determine the efficacy of St. John's Wort (SJW) in the treatment of mild to moderate depression. The Boyak and Lookinland Methodological Quality Index was used to evaluate the studies. Despite methodological concerns, all studies demonstrated a significant drop in the Hamilton Depression Rating Scale scores for clients taking SJW compared with placebo or pharmaceutical antidepressants. Practitioners may find SJW a viable complementary treatment alternative to traditional medical treatment. The results should encourage further research to validate these findings and seek the most appropriate preparations and dosing for this popular herb.

Abstract
Recently, interactions of herbal medicines with synthetic drugs came into focus of particular interest. In the past 3 years, more than 50 papers were published regarding interactions between St. John's wort (Hypericum perforatum L.; SJW) and prescription drugs. Co-medication with SJW resulted in decreased plasma concentrations of a number of drugs including amitriptyline, cyclosporine, digoxin, indinavir, irinotecan, warfarin, phenprocoumon, alprazolam, dextrometorphane, simvastatin, and oral contraceptives. Sufficient evidence from interaction studies and case reports indicate that SJW is a potent inducer of cytochrome P450 enzymes (particularly CYP3A4) and/or P-glycoprotein. Recent studies could show that the degree of enzyme induction by SJW correlates strongly with the amount of hyperforin found in the product. Products that do not contain substantial amounts of hyperforin (<1%) have not been shown to produce clinically relevant enzyme induction. On the other hand, some evidence suggests that hyperforin may also contribute to the antidepressant activity of SJW. However, clinical studies using SJW preparations with a low hyperforin amount (<1%) clearly demonstrated the superiority of this plant extract over placebo and its equivalence to imipramine and fluoxetine in the treatment of mild to moderate forms of depression. In the present paper clinical significant SJW interactions are critically evaluated against the background of hyperforin.

Abstract
BACKGROUND Depression is common in primary care and it is associated with marked personal, social and economic morbidity, and creates significant demands on service providers in terms of workload. Treatment is predominantly pharmaceutical or psychological. Fluoxetine, the first of a group of antidepressant (AD) agents known as selective serotonin reuptake inhibitors (SSRIs), has been studied in many randomised controlled trials (RCTs) in comparison with tricyclic (TCA), heterocyclic and related ADs, and other SSRIs. These comparative studies provided contrasting findings. In addition, systematic reviews of RCTs have always considered the SSRIs as a group, and evidence applicable to this group of drugs might not be applicable to fluoxetine alone. The present systematic review assessed the efficacy and tolerability profile of fluoxetine in comparison with TCAs, SSRIs and newer agents. OBJECTIVES To determine the efficacy of fluoxetine, compared with other ADs, in alleviating the acute symptoms of depression, and to review its acceptability. SEARCH STRATEGY Relevant studies were located by searching the Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register (CCDANCTR), the Cochrane Central Register of Controlled Trials (CENTRAL), Medline (1966-2004) and Embase (1974-2004). Non-English language articles were included. SELECTION CRITERIA Only RCTs were included. For trials which have a crossover design only results from the first randomisation period were considered. DATA COLLECTION AND ANALYSIS Data were independently extracted by two reviewers using a standard form. Responders to treatment were calculated on an intention-to-treat basis: drop-outs were always included in this analysis. When data on drop-outs 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 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 and who experienced adverse reactions out of the total number of randomised patients. The primary analyses used a fixed effects approach, and presented Peto Odds Ratio (PetoOR) and Standardised Mean Difference (SMD). MAIN RESULTS On a dichotomous outcome fluoxetine was less effective than dothiepin (PetoOR: 2.09, 95% CI 1.08 to 4.05), sertraline (PetoOR: 1.40, 95% CI 1.11 to 1.76), mirtazapine (PetoOR: 1.64, 95% CI 1.01 to 2.65) and venlafaxine (Peto OR: 1.40, 95% CI 1.15 to 1.70). On a continuous outcome, fluoxetine was more effective than ABT-200 (Standardised Mean Difference (SMD) random effects: - 1.85, 95% CI - 2.25 to - 1.45) and milnacipran (SMD random effects: - 0.38, 95% CI - 0.71 to - 0.06); conversely, it was less effective than venlafaxine (SMD random effect: 0.11, 95% CI 0.00 to 0.23), however these figures were of borderline statistical significance. Fluoxetine was better tolerated than TCAs considered as a group (PetoOR: 0.78, 95% CI 0.68 to 0.89), and was better tolerated in comparison with individual ADs, in particular than amitriptyline (PetoOR: 0.64, 95% CI 0.47 to 0.85) and imipramine (PetoOR: 0.79, 95% CI 0.63 to 0.99), and among newer ADs than ABT-200 (PetoOR: 0.21, 95% CI 0.10 to 0.41), pramipexole (PetoOR: 0.20, 95% CI 0.08 to 0.47) and reboxetine (PetoOR: 0.61, 95% CI 0.40 to 0.94). AUTHORS' CONCLUSIONS There are statistically significant differences in terms of efficacy and tolerability between fluoxetine and certain ADs, but the clinical meaning of these differences is uncertain, and no definitive implications for clinical practice can be drawn. From a clinical point of view the analysis of antidepressants' safety profile (adverse effect and suicide risk) remains of crucial importance and more reliable data about these outcomes are needed. Waiting for more robust evidence, treatment decisions should be based on considerations of clinical history, drug toxicity, patient acceptability, and cost. We need for large, pragmatic trials, enrolling heterogeneous populations of patients with depression to generate clinically relevant information on the benefits and harms of competitive pharmacological options. A meta-analysis of individual patient data from the randomised trials is clearly necessary.

Abstract
BACKGROUND Extracts of the plant Hypericum perforatum L. (popularly called St. John's wort) have been used in folk medicine for a long time for a range of indications including depressive disorders. OBJECTIVES To investigate whether extracts of hypericum are more effective than placebo and as effective as standard antidepressants in the treatment of depressive disorders in adults; and whether they have have less adverse effects than standard antidepressant drugs. SEARCH STRATEGY Trials were searched in computerized databases (Cochrane Collaboration Depression, Anxiety & Neurosis Group Clinical Trials Registers; PubMed); by checking bibliographies of pertinent articles; and by contacting manufacturers and researchers. SELECTION CRITERIA Trials were included if they: (1) were randomized and double-blind; (2) included patients with depressive disorders; (3) compared extracts of St. John's wort with placebo or standard antidepressants; and (4) included clinical outcomes such as scales assessing depressive symptoms. DATA COLLECTION AND ANALYSIS Information on patients, interventions, outcomes and results was extracted by at least two independent reviewers using a standard form. The main outcome measure for comparing the effectiveness of hypericum with placebo and standard antidepressants was the responder rate ratio (responder rate in treatment group/responder rate in control group). The main outcome measure for adverse effects was the number of patients dropping out for adverse effects. MAIN RESULTS A total of 37 trials, including 26 comparisons with placebo and 14 comparisons with synthetic standard antidepressants, met the inclusion criteria. Results of placebo-controlled trials showed marked heterogeneity. In trials restricted to patients with major depression, the combined response rate ratio (RR) for hypericum extracts compared with placebo from six larger trials was 1.15 (95% confidence interval (CI), 1.02-1.29) and from six smaller trials was 2.06 (95% CI, 1.65 to 2.59). In trials not restricted to patients with major depression, the RR from six larger trials was 1.71 (95% CI, 1.40-2.09) and from five smaller trials was 6.13 (95% CI, 3.63 to 10.38). Trials comparing hypericum extracts and standard antidepressants were statistically homogeneous. Compared with selective serotonin reuptake inhibitors (SSRIs) and tri- or tetracyclic antidepressants, respectively, RRs were 0.98 (95% CI, 0.85-1.12; six trials) and 1.03 (95% CI, 0.93-1.14; seven trials). Patients given hypericum extracts dropped out of trials due to adverse effects less frequently than those given older antidepressants (Odds ratio (OR) 0.25; 95% CI, 0.14-0.45); such comparisons were in the same direction, but not statistically significantly different, between hypericum extracts and SSRIs (OR 0.60, 95% CI, 0.31-1.15). AUTHORS' CONCLUSIONS Current evidence regarding hypericum extracts is inconsistent and confusing. In patients who meet criteria for major depression, several recent placebo-controlled trials suggest that the tested hypericum extracts have minimal beneficial effects while other trials suggest that hypericum and standard antidepressants have similar beneficial effects. As the preparations available on the market might vary considerably in their pharmaceutical quality, the results of this review apply only to the products tested in the included studies.

Abstract
AIM Clinical experience suggests the use of alternative remedies, such as St. John's Wort (SJW), in adolescents with affective disorders is increasing. In view of the paucity of documented, well-established, and safe antidepressant medications for children and adolescents, it was important to investigate the potential usefulness of SJW in adolescents with major depressive disorders (MDD). METHODS AND RESULTS An 8-week, open-label study evaluated the potential efficacy and safety of SJW (300 mg TID) in adolescents with MDD. Twenty-six patients, 12-17 years of age (mean age, 14.8 years) were enrolled in the study. Of the 11 patients who completed the study, 9 patients (82%) showed significant clinical improvement based on Clinical Global Improvement (CGI) change scores (treatment response was indicated by a clinical improvement rating of either very much improved or much improved at the final visit). Of the 15 patients (58%) who did not complete the study, 8 patients were noncompliant and 7 patients were discontinued because of persisting or worsening depression. Of the 8 noncompliant patients, at week 8, 2 patients (25%) remained unchanged, 1 patient (12.5%) was minimally improved, 4 patients (75%) were much improved, and 1 patient (12.5%) was very much improved, based on the CGI change score. CONCLUSION Preliminary findings suggest that SJW is well tolerated and may be clinically effective in the treatment of some adolescents with mild depression. Controlled trials of SJW in adolescents with MDD are suggested.

Abstract
BACKGROUND Extracts of Hypericum perforatum (St John's wort) are widely used to treat depression. Evidence for its efficacy has been criticised on methodological grounds. AIMS To update evidence from randomised trials regarding the effectiveness of Hypericum extracts. METHODS We performed a systematic review and meta-analysis of 37 double-blind randomised controlled trials that compared clinical effects of Hypericum monopreparation with either placebo or a standard antidepressant in adults with depressive disorders. RESULTS Larger placebo-controlled trials restricted to patients with major depression showed only minor effects over placebo, while older and smaller trials not restricted to patients with major depression showed marked effects. Compared with standard antidepressants Hypericum extracts had similar effects. CONCLUSIONS Current evidence regarding Hypericum extracts is inconsistent and confusing. In patients who meet criteria for major depression, several recent placebo-controlled trials suggest that Hypericum has minimal beneficial effects while other trials suggest that Hypericum and standard antidepressants have similar beneficial effects.

Abstract
OBJECTIVE International differences are thought to exist in dosages used by clinicians treating mood disorders. This study examined international dosage differences in antidepressant clinical trials, using a database formed and maintained as a component of a Cochrane review of comparative clinical trials of fluoxetine. METHODS This systematic review included 132 studies. A detailed set of methodological features and results were abstracted from the original publications and entered into an electronic database. Mean and maximum fluoxetine dosages were compared across countries. To evaluate the dosages of comparison medications, a defined daily dosage (DDD) ratio was calculated as the trial mean dosage divided by the DDD for that drug. RESULTS Both the maximum and mean dosages for fluoxetine and comparison medications were higher in trials conducted in the US (fluoxetine weighted mean dosage 49.18 mg; 95% CI, 41.30 to 57.05), compared with trials conducted in Europe (fluoxetine weighted mean dosage 29.98 mg; 95% CI, 25.28 to 34.68). Since most clinical trials were conducted in Europe or the US, we could not determine whether different dosages tended to be used in other regions. CONCLUSIONS International differences in prescriber behaviour may influence, and in turn be influenced by, the conduct of clinical trials. It is difficult to reconcile such differences with the principles of evidence-based medicine.

Abstract
The antiproliferative effect of serotonin-reuptake inhibitors (SSRI) and serotonin antagonists has been demonstrated in prostate tumors. Since Hypericum perforatum components act as serotonin-reuptake inhibitors and exert cytotoxic effects on several human cancer cell lines, in this work we analyzed the effect of a treatment with Hypericum perforatum extract (HPE) on the growth of human prostate cancer cells in vitro and in vivo. This study highlighted a significant reduction of tumor growth and number of metastasis suggesting that this natural compound may be useful in the treatment of prostate cancer.

Abstract
The present study investigated whether the outcome of randomized clinical trials studying fluoxetine favored fluoxetine, where this was the experimental agent, and favored comparator antidepressants in trials where fluoxetine was the reference agent. A systematic review of all double-blind, randomized clinical trials comparing fluoxetine with any other antidepressant drug in patients suffering from depression was carried out. Thirty-seven studies meeting the inclusion criteria were analyzed. A metaregression analysis indicated that, after adjusting for possible confounders, studies where fluoxetine was the experimental agent were positively associated with treatment effect, indicating a significant advantage for fluoxetine. The evidence that the outcome of fluoxetine trials varied according to whether this drug was used as a new compound or a reference one suggests the presence of bias.
