Abstract
Background: Depression is commonly associated with a high-carbohydrate diet, lack of interest in proper oral hygiene and xerostomia connected to the use of antidepressants. Patients often consult their dentists as a result of changes affecting the hard dental substance and the soft-tissues. Aim: The aim of this study was to identify adverse drug interactions between the antidepressants and medications commonly administered in dentistry in order to give practicing dentists an overview of the scientific literature. Objective: The objective is to identify the adverse drug interactions between antidepressants and medication commonly administered in dentistry. Study Design: The literature search was performed using PubMed, Cochrane and the specific search items. The review (1984-2009) focused on medicines used in dental practice (vasoconstrictors, non-opioid analgesics, non-steroidal anti-inflammatory drugs, antibiotics, antifungals and benzodiazepines). Results: There are various drug interactions between antidepressants and medicines used in dentistry. When two or more drugs are co-administered, a drug interaction must always be anticipated though many of the interactions are potential problems, but do not seem to be real clinical issues. Conclusion: The probability of a drug interaction can be minimized by careful history-taking, skillful dose adjustment and safe administration of the therapeutic agent.

Abstract
Haematological malignancies are often treated with haematopoietic stem cell transplants (HSCT). The disease and its treatment are challenging and life threatening, as they not only affect the recipients, but also their families. This review highlights the available data on the psychological, psychiatric and social impact of these illnesses and their treatment on recipients and families. There are robust data that correlate HSCT with emotional distress, as emotional and physical functioning significantly affect quality of life. Psychiatric co-morbidity including anxiety, depression, adjustment and post-traumatic stress disorder, delirium and cognitive deficits have been reported at different stages in the transplant process. This review will highlight the psychosocial and clinical research findings relevant to HSCT patients and will summarize recommendations for future psychosocial research in this population.

Abstract
BACKGROUND Risk of abnormal bleeding in surgery patients prescribed serotonin reuptake inhibitors (SRIs) is unclear. Considering the quantity of literature on abnormal gastrointestinal (GI) bleeding with SRIs, relatively little exists on SRI bleeding risks in surgical procedures. We investigated whether SRIs increase the risk of surgical bleeding in patients undergoing knee and hip total joint replacement. METHODS RA retrospective case-control study was conducted among subjects undergoing primary total hip and knee replacement surgeries from January 2005 to March 2011 at a single institution. The experimental group was defined by utilization of SRIs at the time of surgery (the independent variable). The control group was matched for age, sex, ethnicity, and type of surgery (hip or knee). Any case with preoperative hematocrit <30, platelets <100,000; abnormal prothrombin time, partial-prothrombin time, and international normalized ratio (INR), primary bleeding disorder, medical conditions, or medications associated with increased bleeding was excluded. All cases were randomly selected. RESULTS RA total of 194 subjects (hip 104, knee 90) were included. Statistical analysis was performed on the SRI group (n = 71) and the control, non-SRI group (n = 123). No difference was found between the groups in estimated blood loss, hemoglobin, hematocrit, platelets, PT, PTT, and INR from preoperative to postoperative day 1, 2, and 3. Furthermore, no subjects in either group required blood transfusions. CONCLUSION SRIs were not associated with increased risk of bleeding in primary knee or hip replacement surgeries in this study. The hypothesis that SRIs increase the risk of bleeding based on presumptions about their action on platelet aggregation is uncertain and warrants further study.

Abstract
Drug-drug interactions may contribute to the variability of the response of clopidogrel. Several hypotheses have been proposed concerning the potential modification of clopidogrel pharmacokinetics and pharmacodynamics by fluoxetine. This open-label crossover study assessed the effect of fluoxetine on the pharmacological activity of clopidogrel in healthy volunteers. Eight healthy male volunteers received a single 600-mg loading dose of clopidogrel followed by 20 mg of fluoxetine on 4 days and then 20 mg of fluoxetine plus 600 mg of clopidogrel on the fifth day. Eleven blood samples were withdrawn after clopidogrel administration to determine plasma concentrations of clopidogrel active metabolite (CAM) and platelet function. Platelet aggregation was measured by light transmittance aggregometry (LTA) and platelet reactivity index by flow cytometric vasodilator-stimulated phosphoprotein (VASP) analysis. The areas under the curve and maximum plasma concentrations of CAM were, respectively, 20.6 and 25.3% lower after co-administration of fluoxetine compared with administration of clopidogrel alone. The percentage maximum platelet aggregation values in the presence of 5 μM and 10 μM adenosine diphosphate, measured by LTA, were, respectively, 13.9 and 22.4% lower after fluoxetine co-administration. The platelet reactivity index measured by the flow cytometric VASP method was 36.8% lower when clopidogrel was administered in conjunction with fluoxetine.

Abstract
Depression is a common condition, representing close to 6% of visits to primary care providers. Although minorities are more likely to have chronic depression, they are more likely to be incorrectly diagnosed and less likely to receive treatment when compared to the mainstream population. Screening and appropriate treatment within primary care is recommended in clinical practices that have systems in place to assure accurate diagnosis, effective treatment, and follow-up. This recommendation is especially relevant for treatment of minority populations, as they are more likely to seek care for mental health problems from primary care providers rather than specialists. A number of self-report screening tools that simplify screening are available. Treatment modalities that are supported by evidence are psychotherapy, prescription medications, and electroconvulsive therapy for severe depression. Selective serotonin reuptake inhibitors (SSRIs) have become the cornerstone of therapy for depression since the Food and Drug Administration (FDA) approval of fluoxetine in 1987. No substantial differences in efficacy of SSRIs have been found, although data suggest differences with respect to onset of action and adverse effects that may be relevant in the choice of one medicine over another. Common side effects of serotonin reuptake inhibitors include nausea, diarrhea, insomnia, somnolence and dizziness, akathisia, and sexual dysfunction. While most of these symptoms tend to subside within several weeks of use, sexual dysfunction appears to be a long-term side effect that typically reverses within a few days after discontinuation of the causative medication. Selective norepinephrine reuptake inhibitors (SNRIs), bupropion, mirtazapine, and tricyclic antidepressants (TCAs) are other commonly used medications. Complementary and alternative treatments, such as St. John's wort (Hypericum perforatum), exercise, acupuncture, music therapy, and relaxation, have limited data supporting their efficacy.

Abstract
AIM The aim of this study was to investigate the effects of co-medication with selective serotonin re-uptake inhibitors (SSRIs) on overanticoagulation during acenocoumarol maintenance treatment. METHODS All subjects from The Rotterdam Study who received acenocoumarol maintenance treatment between April 1 1991 and September 9 2009 were followed for the event of an international normalized ratio (INR) ≥6, until death, end of treatment or end of the study period. With the Andersen-Gill extension of the Cox proportional hazards model, risks for repeated events of overanticoagulation in relation to concomitant SSRI use were calculated. RESULTS The risk for overanticoagulation during acenocoumarol maintenance treatment was increased in combination with fluvoxamine (HR 2.63, 95% CI 1.49, 4.66) and venlafaxine (HR 2.19, 95% CI 1.21, 3.99). There was no increase in risk for the other SSRIs, but numbers of exposed cases were low for all SSRIs except paroxetine. CONCLUSION Fluvoxamine and venlafaxine were associated with a more than double risk of INR values ≥6 in acenocoumarol treated subjects.

Abstract
OBJECTIVE The purpose of this study was to examine the frequency of oral bleeding complications after invasive dental procedures in patients taking selective serotonin reuptake inhibitor (SSRI) medications. STUDY DESIGN In this retrospective cohort study, we included dental patients who had invasive dental treatment and were taking an SSRI medication. Data collected included demographics, medical history, dental visits and procedures, and use of adjunctive measures to control bleeding. Primary outcomes included documentation of return visits or phone calls to the dental clinic or emergency department (ED) for oral bleeding, and oral bleeding or use of blood products for inpatients. RESULTS There were 92 patients taking SSRIs who had 145 invasive procedure visits, consisting of extractions, implant surgery, alveoloplasty, periodontal surgery, subgingival scaling and root planning, and biopsy. There were 110 extraction visits yielding a total of 167 extractions. Among all patients, there was 1 return visit to the clinic and 1 telephone call with a chief complaint of oral bleeding. CONCLUSIONS The frequency of oral bleeding complications after invasive dental treatment is low to negligible in patients on SSRI medications.

Abstract
AIMS Anxiety disorders have been shown to be correlated with an activation of coagulation and impairment of fibrinolysis. The aim of the study was to assess whether medication with a serotonergic antidepressant, which has been associated with abnormal bleeding, may modify this effect. METHODS Thirty-one anxiety patients, mostly with comorbid depression, and 31 healthy controls were included in the study. Group differences between anxiety patients medicated with a serotonergic antidepressant, patients without serotonergic antidepressant and controls were assessed for activated partial thromboplastin time, fibrinogen, factor VII, factor VIII, von Willebrand factor, von Willebrand ristocetin cofactor activity, prothrombin fragment 1 + 2, thrombin-antithrombin complex, d-dimer, α2-antiplasmin, plasmin-α2-antiplasmin complex (PAP), tissue plasminogen activator and plasminogen activator inhibitor. Intervening variables, such as age, sex, body mass index and smoking, were accounted for. RESULTS We found lower coagulation measures for fibrinogen (P = 0.03) and plasminogen activator inhibitor (P = 0.01), and higher levels of PAP (P = 0.046) in patients with serotonergic antidepressant than in patients without serotonergic antidepressant. When controlling for smoking and body mass index, differences between the two groups were significant for PAP (P = 0.02), von Willebrand ristocetin cofactor activity (P = 0.02) and activated partial thromboplastin time (P = 0.046). Coagulation scores were similar in patients with serotonergic antidepressant to those of healthy controls. CONCLUSIONS Serotonergic antidepressants may counteract a procoagulant effect of anxiety and/or depression in anxiety patients.

Abstract
An older woman presented to the hospital with abdominal pain and subsequently had three episodes of melaena, requiring blood transfusions. She was known to suffer with severe depression and was on high-dose fluoxetine. Gastroscopy and colonoscopy failed to reveal an underlying cause for gastrointestinal (GI) bleeding. Possibility of high-dose selective serotonin reuptake inhibitors causing GI bleed was raised. Fluoxetine was discontinued and the patient was commenced on mirtazapine. The patient had no further GI bleeding and had significant improvement in haemoglobin.

Abstract
In the present study, we investigated the vasculoprotective effect of sigma-1 receptor stimulation with fluvoxamine on pressure overload hypertrophy-induced vascular injury in the thoracic aorta and defined mechanisms underlying that activity. Wistar rats underwent bilateral ovariectomy, and two weeks later were further treated with abdominal aortic stenosis. To confirm the vasculoprotective role of sigma-1 receptor signaling, we treated rats with the agonist fluvoxamine (at 0.5 and 1.0 mg/kg) and with the antagonist NE-100 (at 1.0mg/kg) for 4 weeks orally once a day after the onset of aortic banding. Interestingly, sigma-1 receptor expression in the thoracic aorta decreased significantly 4 weeks after pressure overload-induced hypertrophy in vehicle treated ovariectomized rats. Fluvoxamine administration significantly attenuated pressure overload-induced vascular injury with concomitant increase in receptor expression and subsequent decrease in IP3 receptor expression. Fluvoxamine treatment also significantly restored pressure overload-induced impaired Akt phosphorylation and stimulated eNOS protein expression as well as Akt-mediated eNOS phosphorylation (Ser1177). Fluvoxamine's vasculoprotective effect was nullified by co-administration of a sigma-1 receptor antagonist. No changes in phosphorylation of ERK1/2 or PKCα in the aorta were observed following pressure overload and after fluvoxamine treatment. Our findings confirm, for the first time, a potential role for sigma-1 receptor expression and signaling in the thoracic aorta in attenuating hypertrophy-induced vascular injury in ovariectomized rats. Thus, we demonstrate, for the first time, a potential role in the thoracic aorta for sigma-1 receptor expression and signaling via Akt-eNOS in attenuating hypertrophy-induced vascular injury in ovariectomized rats.

Abstract
The pharmacological treatment of older adults with major depressive disorder presents a variety of challenges, including a relative lack of high quality studies designed to measure the efficacy and safety of antidepressants specific to this patient population. Gaining a clear understanding of how to use antidepressants in elderly patients with depression, especially new and widely used agents, would provide valuable insight to clinicians. The purpose of the current article is to review the pharmacology, efficacy and safety of newer antidepressants (i.e. escitalopram, duloxetine and desvenlafaxine) in the treatment of late-life depression. To accomplish this goal, a MEDLINE and PubMed search (1966 - February 2010) was conducted for relevant articles. Animal and human studies have clearly demonstrated the effects of desvenlafaxine, duloxetine and escitalopram on monoamine reuptake transporters. The serotonergic and noradrenergic actions of desvenlafaxine and duloxetine may provide for a faster onset of antidepressant activity in the elderly, but more definitive data are needed and the clinical effects of the possible faster onset of action need to be elucidated. Duloxetine and escitalopram are extensively metabolized via cytochrome P450 (CYP) enzymes and the decreased hepatic metabolism present in many older adults should be taken into account when prescribing these medications. Duloxetine possesses the greatest likelihood of producing clinically relevant drug-drug interactions because of its inhibition of CYP2D6. All three agents must also be used cautiously in older adults with poor renal function. In terms of clinical efficacy, 14 prospective published trials involving escitalopram (n = 8) and duloxetine (n = 6) in the treatment of older adults with major depressive disorder were identified. No such studies involving desvenlafaxine were found. Of the five randomized, double-blind, controlled trials, 46% and 37% of antidepressant-treated patients were considered responders and remitters, respectively. In contrast to escitalopram, duloxetine-treated patients experienced improvements in depressive symptoms that more consistently differentiated themselves from the symptoms of placebo-treated patients. Escitalopram and duloxetine were generally well tolerated, but 5-20% and 10-27% of patients, respectively, dropped out because of medication-related adverse effects. Adverse effects experienced by older adults were generally similar to those experienced by younger adults, although indirect comparisons suggest that older adults are more likely to experience dry mouth and constipation with duloxetine and escitalopram, while orthostasis may be more common in older adults prescribed desvenlafaxine. Overall, duloxetine and escitalopram represent modestly effective treatments for late-life depression that are generally well tolerated but do produce a variety of adverse effects. Conclusions regarding desvenlafaxine cannot be made at this time because of a lack of geriatric-specific data.

Abstract
Selective serotonin reuptake inhibitors (SSRIs) are known to reduce post-myocardial infarction-induced morbidity and mortality. However, the molecular mechanism underlying SSRI-induced cardioprotection remains unclear. Here, we investigated the role of σ(1)-receptor (σ(1)R) stimulation with fluvoxamine on myocardial hypertrophy and cardiac functional recovery. Male ICR mice were subjected to transverse aortic constriction (TAC) in the cardiac aortic arch. To confirm the cardioprotective role of fluvoxamine by σ(1)R stimulation, we treated mice with fluvoxamine (0.5 or 1 mg/kg) orally once per day for 4 wk after the onset of aortic banding. Interestingly, in untreated mice, σ(1)R expression in the left ventricle (LV) decreased significantly over the 4 wk as TAC-induced hypertrophy increased. In contrast, fluvoxamine administration significantly attenuated TAC-induced myocardial hypertrophy concomitant with recovery of σ(1)R expression in the LV. Fluvoxamine also attenuated hypertrophy-induced impaired LV fractional shortening. The fluvoxamine cardioprotective effect was nullified by treatment with a σ(1)R antagonist [NE-100 (1 mg/kg)]. Importantly, another SSRI with very low affinity for σ(1)Rs, paroxetine, did not elicit antihypertrophic effects in TAC mice and cultured cardiomyocytes. Fluvoxamine treatment significantly restored TAC-induced impaired Akt and endothelial nitric oxide synthase (eNOS) phosphorylation in the LV. Our findings suggest that fluvoxamine protects against TAC-induced cardiac dysfunction via upregulated σ(1)R expression and stimulation of σ(1)R-mediated Akt-eNOS signaling in mice. This is the first report of a potential role for σ(1)R stimulation by fluvoxamine in attenuating cardiac hypertrophy and restoring contractility in TAC mice.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) have been shown to increase bleeding risks. This study examined the association of perioperative coronary artery bypass grafting (CABG) bleeding risks and SSRI use prior to CABG. HYPOTHESIS SSRI may be associated with increased bleeding risks after CABG resulting in elevated reoperation rates due to bleeding complications. METHODS Patients who underwent CABG between 1999 and 2003 (n = 4794) were identified in a tertiary medical center. SSRI use (n = 246) was determined using inpatient pharmacy records. Outcomes included primary end point of reoperation due to bleeding complications and other secondary measures. Multivariate regression models were constructed to adjust for baseline differences between SSRI and control groups. RESULTS Reoperation due to bleeding complications among SSRI users was not significantly different (odds ratio [OR]: 1.14 (0.52-2.47); P = 0.75) compared to the control group. Other secondary outcomes and 30-day mortality (2.0% in SSRI vs 2.1% in control group; P = 0.92) between the 2 groups were similar. However, the adjusted total volume of postoperative red blood cell (RBC) units transfused was higher in the SSRI group. CONCLUSION We conclude that there is no compelling evidence to limit the use of SSRIs among patients with coronary artery disease who undergo CABG given the current evidence. Further research may be needed on individual SSRI medications.

Abstract
OBJECTIVE We here investigated the effect of sigma-1 receptor (Sig-1R) stimulation with fluvoxamine on myocardial hypertrophy, cardiac functional recovery and defined mechanisms underlying its cardioprotective action. METHODS Wistar rats subjected to bilateral ovariectomy (OVX) were treated with abdominal aortic banding between the right and left renal arteries. To confirm the cardioprotective role of Sig-1R stimulation, we treated the rats with Sig-1R agonist (fluvoxamine, 0.5 and 1 mg/kg) orally once a day for 4 weeks after the onset of aortic banding. RESULTS Interestingly, the expression of Sig-1R in the left ventricle (LV) decreased significantly 4 weeks after pressure overload (PO)-induced hypertrophy in OVX rats. The fluvoxamine administration significantly attenuated PO-induced myocardial hypertrophy with concomitant increase in the expression of Sig-1R in LV. Fluvoxamine also attenuated hypertrophy-induced impaired LV functions. The cardioprotective effect of fluvoxamine was nullified by treatment with Sig-1R antagonist (NE-100; 1 mg/kg). Fluvoxamine treatment significantly restored PO-induced impaired eNOS and Akt activity in the LV. CONCLUSION We here found, for the first time, the potential role of Sig-1R expression in the heart in attenuating PO-induced hypertrophy in OVX rats. Fluvoxamine treatment protects PO-induced cardiac injury via upregulation of Sig-1R and stimulation of Sig-1R-mediated Akt-eNOS signaling in ovariectomized rats.

Abstract
Treatment with selective serotonin reuptake inhibitors (SSRI) increases the risk of gastrointestinal bleeding. The combination with non-steroidal anti-inflammatory drugs (NSAIDs) further augments this hazard. Particular precaution is also necessary in patients on platelet aggregation inhibitors, with a known bleeding disorder or preceding gastrointestinal lesions. The incidence of bleeding events apart from the gastrointestinal tract, e.g. intracerebral hemorrhages, is not cumulated under SSRI treatment. This also applies for the combination of SSRI and coumarin or aspirin. Prescribing doctors have to be aware of the bleeding risks of SSRI and should explain this to their patients. High-risk patients have to be followed up closely and an SSRI with a low potential for drug interaction should be used. The prescription of gastroprotective agents and a change of the antidepressant should be considered in particular cases. We provide a literature survey and recommendations for the clinical routine.

Abstract
SUMMARY BACKGROUND Antiplatelet drug use increases bleeding risk, but its role in precipitating subarachnoid hemorrhage remains unclear. OBJECTIVES We examined whether the use of low-dose acetylsalicylic acid (LDA), clopidogrel or dipyridamole increased the risk of subarachnoid hemorrhage. PATIENTS/METHODS This population-based case-control study was conducted in northern Denmark. We used the Danish National Patient Registry to identify all persons admitted to neurosurgery or neurology departments with a first diagnosis of subarachnoid hemorrhage between 1997 and 2008 (n = 1186). Using risk-set sampling, we selected 10 population controls (n = 11 840) for each case, matched by age and sex. We obtained data on prescriptions for antiplatelet drugs, use of other medications and comorbidity from medical databases. We used conditional logistic regression to compute odds ratios with 95% confidence intervals (CIs), controlling for confounding factors. RESULTS One hundred and nine cases (9.2%) and 910 controls (7.7%) used antiplatelet drugs. Among cases, 104 (8.8%) used LDA and 11 (0.9%) used dipyridamole. Among controls, 891 (7.5%) used LDA and 48 (0.4%) used dipyridamole. As compared with not using any antiplatelet drugs during the study period, the adjusted odds ratios were 1.03 (95% CI 0.81-1.32) for long-term LDA use, 2.52 (95% CI 1.37-4.62) for new LDA use, and 2.09 (95% CI 1.04-4.23) for long-term dipyridamole use. Owing to the low number of users, data were inconclusive for clopidogrel. CONCLUSIONS Long-term dipyridamole use and new LDA use were associated with an increased risk of subarachnoid hemorrhage. Because of the limited precision of these risk estimates, however, caution is advised in their interpretation. Long-term LDA use was not associated with subarachnoid hemorrhage.

Abstract
Although the selective serotonin reuptake inhibitors (SSRIs), which are now widely used as a first-line treatment for depression and many other psychiatric conditions, are generally well tolerated, they are not devoid of side effects. Most short-term treatment-related side effects of SSRIs are transient and disappear after a few days or weeks. However, following long-term treatment with the SSRIs, some serious adverse events may occur. Some of them can be difficult to recognise because they can resemble residual symptoms of depression. The most serious can be life threatening. They all have a negative influence on the patient's quality of life and are frequently a prime reason for a lack of long-term compliance with the associated increased risk of recurrence of a depressive episode. This article is an overview of the more common adverse events, which are seen with non-acute treatment with the SSRIs.

Abstract
Depression is a common co-morbid condition in patients suffering from a variety of chronic medical conditions. In spite of this, mental health of patients with chronic kidney disease is understudied. Accurate estimation of the prevalence of depressive disorders in this population is difficult due to the different definitions and assessment techniques and the overlap of depressive symptomatology with symptoms of uremia. Several potential pathways link depression and chronic kidney disease. The association between the two conditions is probably bidirectional. Consequently, treatment of mood disorders could impact medical outcome. Very little has been published about the therapeutic options for depression in patients with chronic kidney disease. Available data, however, suggest that several antidepressant medications and psychotherapeutic methods are likely to be safe and effective also in this population. In this review, which is the second of a series of reviews on this topic, we provide an overview of the literature concerning the diagnosis, screening and therapy of depressive disorders in patients with chronic kidney disease.

Abstract
Neuronal accumulation of 1-methyl-4-phenylpyridinium ion (MPP(+)), the metabolite of neural toxin, 1-methyl-4-phenyl-1,2,3,6-tetrahyropyridine (MPTP), induces a rapid depletion of cellular ATP level and loss of neuronal cell viability which simulates human Parkinson's disease (PD). Since ATP plays an important role in the physiology and function of platelets, which share many biochemical and physiological features with neuronal cells, we examined the effect of MPP(+) on platelet aggregation and viability using freshly isolated rat platelets. While the treatment of MPP(+) to platelets did not induce cytotoxicity, it significantly attenuated agonist-induced platelet aggregation in a concentration dependent manner. The inhibition of aggregation by MPP(+) was mediated by the depletion of the cytoplasmic ATP pool and resultant decreased ATP secretion. Different from the previous reports in neuronal cells, MPP(+) did not affect intracellular levels of glutathione and cytoplasmic Ca(2+) in platelets. The combined treatment with MPP(+) and 2-deoxyglucose, a glycolysis inhibitor, showed the additive effect in the decrease of ATP secretion and intracellular content. Consistent with these findings, inhibitory effects of MPP(+) on platelet aggregation was significantly enhanced by the treatment with 2-deoxyglucose. In conclusion, these results suggested that MPP(+) can induce ATP depletion in platelets and attenuate platelet aggregation providing a new theory on the reduced platelet activities in PD patients.

Abstract
AIM To determine if levels of coated-platelets, which are potentially pro-thrombotic, are increased in end-stage renal disease patients on haemodialysis, a condition associated with high cardiovascular disease risk. METHODS In a cross-sectional observational study, coated-platelet levels were measured by flow cytometry in 25 end-stage renal failure haemodialysis patients and 25 controls without renal disease. Associations between coated-platelet levels and clinical and biochemical factors relevant to renal and cardiovascular disease were evaluated. RESULTS Mean +/- SD coated-platelet levels were higher in the dialysis group than in the control group (39.3+/-14.3% vs 30.9+/-10.3%, P=0.02). The number of subjects with high coated-platelet levels (>40%) was larger in the dialysis than in the control group (13/25 vs 4/25, chi(2) test, P=0.007). On univariate analysis, coated-platelet levels correlated with serum C-reactive protein levels in renal failure (r=0.47, P=0.02) and inversely with white cell count in the control group (r= -0.60, P=0.001). Coated-platelet levels were higher in dialysis patients reporting alcohol abstinence than among those reporting 'social' drinking (44.3+/-12.6 vs 28.8+/-13.5%, P=0.01). Age, gender, body weight, smoking, diabetes, lipid levels and lipid-lowering drugs were not associated with coated-platelet levels (all P>0.05). CONCLUSION Coated-platelet levels are increased in haemodialysis patients relative to subjects with normal renal function, and are related to inflammation and alcohol abstinence. Other vascular risk factors, such as smoking, lipids and diabetes, were not related to coated-platelet levels. Coated-platelets may be implicated in the increased thrombosis and vascular risk in end-stage renal disease.

Abstract
OBJECTIVES The use of the common antidepressant class of serotonin-specific reuptake inhibitors (SSRIs) is associated with an increased risk of upper gastrointestinal bleeding (UGIB). Proton pump inhibitors (PPIs) have been demonstrated to reduce the risk of gastrointestinal bleeding secondary to other risk factors, most notably non-steroidal anti-inflammatory drug (NSAID) use. The role for PPIs in chronic SSRI users without other risk factors remains uncharacterized. METHODS We used the Manitoba Population Health Research Data Repository to perform a population-based matched case-control analysis. All patients admitted to the hospital with a primary diagnosis of UGIB were matched to non-bleeding controls. We used conditional regression analysis to determine the risk of UGIB associated with SSRI use, and the risk reduction associated with concomitant PPI use, both for users and non-users of NSAIDs. RESULTS SSRI use was associated with a modest increase in the risk of UGIB (odds ratio (OR), 1.43; 95% confidence interval (CI), 1.09-1.89). The addition of an SSRI to NSAID therapy did not significantly increase the risk of UGIB (OR, 1.20; 95% CI, 0.78-1.92) over use of an NSAID alone. PPI co-therapy significantly reduced the risk of SSRI-related UGIB (OR, 0.39; 95% CI, 0.16-0.94). CONCLUSIONS SSRI use is associated with a modestly increased risk of UGIB, which may be significantly reduced with PPI co-therapy. SSRI use is not a major risk factor for NSAID-related UGIB.

Abstract
OBJECTIVE This study aimed to determine whether the degree of serotonin (5-HT) reuptake inhibition affects risk of hemorrhagic stroke associated with antidepressant use in patients with depression. METHOD A population-based, nested case-control study was performed using a managed care medical claims database. Ninety two depressed patients with a diagnosis of hemorrhagic stroke were identified and matched with 552 controls by age, sex, and year of index date of depression (IDD). Diagnoses of depression, hemorrhagic stroke, and other medical comorbidities were identified using ICD-9 codes. Antidepressants were classified as high, medium, or low reuptake inhibition based on their affinities for the 5-HT reuptake transporter, determined using their respective equilibrium dissociation constants (K(D); high: K(D) < 1 nM; medium: 1 <or= K(D) < 10 nM; low: K(D) >or= 10 nM). Conditional logistic regression analysis was performed to estimate the crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) of the risk of hemorrhagic stroke. RESULTS Compared to non-users of antidepressants, risk of hemorrhagic stroke did not significantly differ between patients who had ever used antidepressants with high (OR = 0.82; 95% CI = 0.44-1.55), medium (OR = 0.93; 95% CI = 0.37-2.31), or low (OR = 0.38; 95% CI = 0.11-1.41) 5-HTT inhibition. CONCLUSION Risk of hemorrhagic stroke associated with antidepressant use may not be related to an antidepressant's degree of 5-HT reuptake inhibition. Given the limitations of this study, additional studies are needed to confirm these findings.

Abstract
BACKGROUND: Blood products derived from donors on medication can contain drugs which might pose a risk for the recipients or influence the quality of the product itself. MATERIAL AND METHODS: To judge the eligibility of blood donors on medication, 4 drug classes have been formed with respect to their pharmacological properties, and blood products have been divided in accordance with their single-donor plasma contents. RESULTS: For drugs with dose-dependent pharmacodynamics, no deferral periods are necessary for donation of blood products containing less than 50 ml single-donor plasma for application to adults. Waiting periods of t(max) + 5 t(1/2) were calculated for the other blood products. Teratogenic drugs do not require special considerations (exception: retinoids, thalidomide and lenalidomide, dutasteride or finasteride with waiting periods for all blood products). A deferral period of t(max) + 24 t(1/2) is proposed for every blood product from blood donors on genotoxic drugs. Drugs without systemic effects can be neglected. Irreversible inhibitors of platelet function cause a 10-day waiting period if production of platelet concentrates is intended. CONCLUSION: Donors on medication are allowed to donate blood for blood products containing less than 50 ml plasma of a single donor, like red blood cell concentrates, for the use in adults without deferral periods, except those taking retinoids, thalidomide, lenalidomide, dutasteride, finasteride, or genotoxic drugs.

Abstract
This study assessed the risk of any bleeding abnormalities, including the risk of gastrointestinal bleeding, associated with antidepressant exposure. We used a case-control methodology. Case patients were individuals admitted with a diagnosis of abnormal bleeding. Control subjects were individuals admitted on the same date without evidence of abnormal bleeding. During the study period, 11,025 case patients were admitted for bleeding abnormalities (matched with 21,846 eligible control subjects), and 1008 were admitted for gastrointestinal bleeding (matched with 1990 eligible control subjects). With respect to any bleeding abnormalities, antidepressants as a group were not associated with an increased risk (adjusted odds ratio [OR], 0.99; 95% confidence interval [CI], 0.90-1.08). Similarly, selective serotonin reuptake inhibitors as a group, the group of tricyclic and related antidepressants, and the group of other antidepressants were not associated with an increased risk of bleeding. With respect to gastrointestinal bleeding abnormalities, antidepressants as a group were associated with a modestly increased risk (adjusted OR, 1.34; 95% CI, 1.01-1.80). Whereas the group of tricyclic and related antidepressants was not associated with an increased risk of bleeding, the group of selective serotonin reuptake inhibitors was associated with a nonsignificant trend toward an increased risk of bleeding (adjusted OR, 1.31; 95% CI, 0.91-1.88) and the group of other antidepressants with a statistically significant increase in the risk of bleeding (adjusted OR, 1.74; 95% CI, 1.04-2.93). In a population with a low baseline risk of bleeding, we detected a significant increase in the risk of gastrointestinal bleeding only.

Abstract
BACKGROUND Because of the prominence of pain-related conditions and the growing complexities of clinical management we aimed to explore and attempt to dispel the several myths that surround these serious therapeutic issues. AIMS We aimed to provide a careful analysis of the evidence and draw factually based guidance for physicians who manage the broad range of patients with pain. METHODS Current myths were identified based on the authors' clinical, scientific, and academic experience. Each contributor addressed specific topics and made his own selection of primary references and systematic reviews by searching in MEDLINE, EMBASE, and CINAHL databases (1990-2008) as well as in the proceedings of the major digestive and rheumatology meetings. The writing and references provided by each contributor were collectively analyzed and discussed by all authors during several meetings until the final manuscript was prepared and approved. RESULTS Seven major 'historical' myths that may perpetuate habits and beliefs in clinical practice were identified. Each of them was thoroughly examined and dispelled, drawing conclusions that should help guide physicians to better manage patients with pain. CONCLUSIONS Pain relief must be considered a human right, and patients with osteoarthritis pain should be treated appropriately with analgesic or/and anti-inflammatory drugs. The risk of gastrointestinal (GI) complications with traditional non-steroidal anti-inflammatory drugs (t-NSAIDs) is present from the first dose (with both short-term and long-term use), and strategies to prevent GI complications should be considered regardless of the duration of therapy. Compared with t-NSAIDs, coxib use is associated with a small but significant reduction of dyspepsia. While protecting the stomach, proton pump inhibitors do not prevent NSAID-induced intestinal damage. To this end, coxib therapy could be the preferred option, although further randomized studies are needed. A substantial number of patients who need NSAIDs are also taking low-dose aspirin for cardiovascular prophylaxis. From a GI perspective, the combination of aspirin plus a coxib provides a preferred option compared with aspirin plus a t-NSAID, for patients at high GI risk. As the incidence of renovascular adverse effects with t-NSAIDs and coxibs is similar, blood pressure should be monitored and managed appropriately in patients taking these drugs, although they should be avoided in those with severe congestive heart failure. Due to increased cardiovascular risk, which is dependent on the dose, duration of therapy, and base-line cardiovascular risk, both t-NSAIDs and coxibs should be used with caution in patients with underlying prothrombotic states and/or concomitant cardiovascular risk factors.

Abstract
Psychiatric medications are frequently an essential component of care for critically ill patients. Their use may lead to medical complications, however, as a result of (1) direct toxicity from psychotropic medications, (2) drug-drug interactions, or (3) intoxication or withdrawal states. These complications may be a nuisance (eg, dry mouth and nausea) or serious and life-threatening (eg, neuroleptic malignant syndrome and cardiac arrhythmias). This article addresses the most important medical complications (organized by organ systems) of psychiatric treatment.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased bleeding tendency. OBJECTIVES To prospectively quantify the dose-response effects of paroxetine and the influence of the serotonin transporter gene (SLC6A4) promoter polymorphism (5-HTTLPR) on platelet function. METHODS Nineteen drug-free psychiatric outpatients (44.5 +/- 10.8 years) were tested before and after 6 weeks of paroxetine treatment (20 mg day(-1)). Based on clinical symptoms, paroxetine dosages were increased (40-50 mg day(-1)) for 6 more weeks in 11 patients. Parameters related to platelet function were assessed by bleeding time, platelet function analyzer (PFA), platelet serotonin, platelet factor 4 (PF4), beta-thromboglobulin (beta-TG), and aggregation tests. RESULTS Paroxetine 20 mg day(-1) increased mean bleeding time by 1.2 min (95% confidence interval (95% CI) -0.2-2.7) and reduced median platelet serotonin level (463 ng 10(-9) platelets; inter quartile range (IQR) 361-666), and platelet ss-TG concentration (3.1 IU 10(-6) platelets; IQR 0.3-6.0). Other platelet parameters did not change significantly. Serial platelet aggregation tests did not become abnormal. Paroxetine dose-escalation did not further influence platelet function. However, 5-HTTLPR polymorphisms modified these effects: in L(A)/L(A)-carriers, bleeding times did not change (-0.2 min; 95% CI -0.6 to 0.9), while bleeding times significantly increased in <2L(A)-allele carriers (2.3 min; 95% CI 0.5 to 4.07; P = 0.032). Platelet serotonin decreases were larger in patients without L(A)-alleles (868 ng 10(-9) platelets; IQR 585 to 1213) than in > or =1 L(A)-allele carriers (457 ng 10(-9) platelets; IQR 392 to 598; P = 0.035). PFA closure time and PF4 increased significantly in patients without L(A)-alleles. CONCLUSIONS Paroxetine 20 mg day(-1) does not increase overall bleeding time, but impairs platelet function by decreasing the levels of platelet serotonin and platelet ss-TG. These paroxetine effects appear to be mediated by 5-HTTLPR, with most pronounced effects in patients without L(A)-alleles.

Abstract
Depression, ischaemic heart disease and cerebrovascular disease are important causes of morbidity and are among the leading contributors to global health burden. These conditions often occur in the same patient, resulting in considerably greater effect on health than combinations of chronic diseases without depression. The frequent occurrence of these conditions in the same patient raises the possibility of a common genetic predisposition, similar risk factors or a pathophysiological link. Serotoninergic and adrenergic signalling play important roles in causing major depression and also in platelet activation and aggregation, which underlies vascular disease. This review discusses the potential pathophysiological link between major depression and conditions in which platelet activation plays an important role and also provides evidence linking the use of the most commonly used antidepressant drugs (i.e. the selective serotonin re-uptake inhibitors) to increased risk of bleeding.

Abstract
Depression accelerates the development and progression of cardiovascular disease and confers an increased risk of mortality. Platelets share biochemical similarity with the central nervous system, particularly in the uptake, storage, and metabolism of serotonin. Given this similarity, and considering the central role of platelets in the biology of cardiovascular disease, it is highly plausible that platelets play an important role in the increased cardiovascular risk of patients with depression. This article provides a comprehensive review of the evidence in this area and shows that the relationship between depression and platelet function is hardly straightforward. Whereas many studies have found that patients with depression have exaggerated platelet activation, quite a number of others show no such relationship or even lower levels of platelet activation in patients with depression. Larger, carefully designed, adequately powered studies with standardized methods of assessing platelet function are needed to address this issue.

Abstract
Depression in patients with coronary artery disease is associated with increased cardiovascular morbidity and mortality. It is not clear, however, if treatment with selective serotonin reuptake inhibitors (SSRIs) decreases the rate of future cardiovascular events. This paper reviews the available literature regarding the effect of SSRI use on cardiovascular outcomes. Thirteen studies addressing this issue were identified. Of these, 5 concluded that SSRI use is associated with decreased cardiovascular morbidity or mortality, 2 concluded that SSRI use was associated with worsened prognosis, and 6 studies found no statistically significant association. Almost all of the published literature examining the effect of SSRIs on cardiovascular outcomes is based on observational studies, thereby precluding definitive conclusions. Randomized controlled studies are clearly needed to definitively address this issue.

Abstract
Depressive syndromes in chronic heart failure (CHF) are common and are associated with a poorer prognosis, particularly with increased morbidity and mortality. CHF as a severe physical disorder may increase the risk of developing depressive syndromes or vice-versa as an interaction of possible common psycho-organic etiological aspects. Depression in CHF is associated with impaired NYHA status and daily activities, resulting in enhanced hospitalisation rates and medical costs with a great impact on long-term health. Only a fraction of comorbid patients receives antidepressants. Therefore, identification of risk factors and prevention by optimizing cardiological and psychiatric therapeutic strategies appear essential for these patients. Early diagnosis and treatment of both CHF and depression may prevent further pathophysiological effects on the heart and brain. This review gives a comprehensive overview of the occurrence, risk factors and shared pathophysiology of depression in CHF, and focuses on improving insufficient diagnosis and therapy of depression. Special attention is given on the cardiac effects of psychopharmacological and alternate non-pharmacological antidepressant therapy in CHF. Recommendations are made for treating depression in CHF patients for a better prevention of this disabling physical and psychosocial condition.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT From case reports it has become clear that selective serotonin reuptake inhibitors (SSRIs) can cause bleeding disorders. The causative mechanism is as yet unknown. Several publications have described the relationship between the serotonin transporter genotype and the prevalence of certain diseases such as depression, but few have focused on the relationship with side-effects of antidepressive drugs such as SSRIs. WHAT THIS STUDY ADDS This study suggests that the association between SSRI therapy and prolonged bleeding time may not be related to the polymorphism of the serotonin transporter (5-HTTLPR) investigated. AIMS Selective serotonin reuptake inhibitors (SSRIs), such as paroxetine, are associated with an increased risk of bleeding disorders, probably due to decreased platelet serotonin levels. Polymorphisms in the serotonin transporter gene (5-HTT) may influence the risk of SSRI-induced bleedings. The aim of this study was to investigate whether and to what extent the serotonin transporter polymorphism increases the bleeding time in paroxetine users. METHODS A prospective study, using routinely collected hospital and pharmacy data, was conducted among 43 patients between 18 and 70 years old and on >4 weeks of paroxetine therapy. The genotype for the serotonin transporter (5-HTTLPR), trough paroxetine levels, platelet function analyser (PFA)-closure time (collagen/epinephrine) and a complete blood count were assessed. RESULTS No significant difference was seen between the SS, SL, LL genotypes of the serotonin transporter and the PFA-closure time. None of the covariates had a significant influence on the association between the serotonin transporter polymorphism and the PFA-closure time. Age and von Willebrand factor showed the largest contribution, but not significant. No difference was seen between the PFA-closure time and the frequency of bruising and spontaneous bleedings between patients with at least one S allele and with the LL genotype. CONCLUSION Our prospective study does not support the assumption that paroxetine can cause a prolonged PFA-closure time during paroxetine therapy due to a serotonin transporter polymorphism. Old age, use of platelet inhibitors and a history of gastrointestinal bleeding remain the focus for SSRI-induced bleeding complications.

Abstract
BACKGROUND Eight analgesic preparations with approved indications for acute pain were among the top 200 drugs prescribed in the United States in 2006. In addition, an estimated 36 million Americans use over-the-counter (OTC) analgesics daily. Given this volume of use, it is not surprising that a number of drug interactions involving analgesic drugs have been reported. OBJECTIVES This article examines the pharmacologic factors that enhance the clinical relevance of potential drug interactions and reviews the literature on drug interactions involving the most commonly used analgesic preparations in the United States. METHODS A PubMed search was conducted for English-language articles published between January 1967 and July 2007. Among the search terms were drug interactions, acetaminophen, aspirin, ibuprofen, naproxen, celecoxib, NSAIDs, hydrocodone, oxycodone, codeine, tramadol, OTC analgesics, alcohol, ethanol, antihypertensive drugs, methotrexate, warfarin, SSRIs, paroxetine, fluoxetine, sertraline, citalopram, serotonin syndrome, MAOIs, and overdose. Controlled clinical trials, case-control studies, and case reports were included in the review. RESULTS A number of case reports and well-controlled clinical trials were identified that provided evidence of the relatively well known drug-drug interactions between prescription/OTC NSAIDs and alcohol, antihypertensive drugs, high-dose methotrexate, and lithium, as well as between frequently prescribed narcotics and other central nervous system depressants. In contrast, the ability of recent alcohol ingestion to exacerbate the hepatotoxic potential of therapeutic doses of acetaminophen is not supported by either case reports or clinical research. Use of ibuprofen according to OTC guidelines in patients taking cardioprotective doses of aspirin does not appear to interfere with aspirin's antiplatelet activity, whereas chronic prescription use of ibuprofen and other NSAIDs may interfere. Low-dose aspirin intake appears to abolish the gastroprotective effects of cyclooxygenase-2-selective inhibitors, including celecoxib. There is evidence of other less well known and potentially clinically significant drug-drug interactions, including the ability of selective serotonin reuptake inhibitors to inhibit the analgesic activity of tramadol and codeine through inhibition of their metabolic activation, to induce serotonin syndrome when used chronically in the presence of high doses of tramadol through synergistic serotonergic action, and to increase the potential for gastrointestinal bleeding associated with NSAID therapy through additive or supra-additive antiplatelet activity. CONCLUSIONS Considering the widespread use of analgesic agents, the overall incidence of serious drug-drug interactions involving these agents has been relatively low. The most serious interactions usually involved other interacting drugs with low therapeutic indices or chronic and/or high-dose use of an analgesic and the interacting drug.

Abstract
Almost all classes of psychotropic agents have been reported to cause blood dyscrasias. Mechanisms include direct toxic effects upon the bone marrow, the formation of antibodies against haematopoietic precursors or involve peripheral destruction of cells. Agranulocytosis is probably the most important drug-related blood dyscrasia. The mortality from drug-induced agranulocytosis is 5-10% in Western countries. The manifestations of agranulocytosis are secondary to infection. Aggressive treatment with intravenous broad-spectrum antimicrobials and bone marrow stimulants may be required. Of drugs encountered in psychiatry, antipsychotics including clozapine (risk of agranulocytosis approximately 0.8%, predominantly in the first year of treatment) and phenothiazines (chlorpromazine agranulocytosis risk approximately 0.13%), and antiepileptics (notably carbamazepine, neutropenia risk approximately 0.5%) are the most common causes of drug-related neutropenia/agranulocytosis. Drugs known to cause neutropenia should not be used concomitantly with other drugs known to cause this problem. High temperature and other indicators of possible infection should be looked for routinely during treatment. Clozapine is well known as a drug that can cause blood dyscrasias, but olanzapine and other atypicals may also cause similar problems. In addition to genetic factors, there are likely to be dose-related and immunological components to these phenomena. Important lessons have been learnt from the haematological monitoring that is necessary with clozapine and the monitoring has been very successful in preventing deaths related to clozapine-induced agranulocytosis. Continuing research into the mechanisms of drug-induced neutropenia and agranulocytosis may serve to further enhance the safe use not only of clozapine, but also of other agents.

Abstract
Depression is prospectively associated with increased risk of coronary artery disease in individuals initially free of clinical cardiovascular disease probably by an increased platelet activity. The serotonergic receptors mainly implied in depression are 5-HT1A and 5-HT2 receptors. Activation of 5HT2 receptor induces platelet aggregation. Drugs with 5-HT1A receptor agonist and 5-HT2A receptor antagonist effects reduced the receptor-mediated platelet aggregation. There are only indirect data about 5-HT1A receptors presence in platelet membranes, thus our aims were to study the characteristics of the platelet membranes 5-HT1A binding sites of both healthy volunteers and patients with cardiac valve disease and ischemic cardiopathy. The bound of the 5-HT1A selective agonist 3H-8OH-DPAT to the platelet membranes 5-HT1A binding sites of patients with cardiac valve disease and ischemic cardiopathy were compared with a control group of healthy voluntaries using radioligand binding methods. The patients with cardiovascular disease showed a reduction (-50.40%) (p<0.01) of the 3H-8OH-DPAT bound to the platelet membranes 5-HT1A receptors (1.652+/-0.79 fmol/mg protein) with respect to the control group (3.331+/-0.16 fmol/mg protein). 3H-8OH-DPAT binding to human platelet membranes is saturable, of high affinity, and seems selective for 5-HT1A receptors, and similar to that described in animal brain and in other human cells. Patients with ischemic cardiopathy and cardiac valve disease showed a reduction of the 8OH-DPAT bound to the platelet membranes. Taken together, these findings suggest that the 8OH-DPAT bound to the human platelet membranes is modulated by modifications produced by cardiovascular disease conditions.

Abstract
Vitamin B12 deficiency is associated with problems in cognition, mood, psychosis, and less commonly, anxiety. Folate deficiency primarily is associated with problems in mood. Patients who have sickle cell disease, a disease of chronic pain, experience difficulties with depression, anxiety, stigma, and are at risk for substance abuse and dependence. Patients with hemophilia have benefited from advances in treatment; however, their morbidity and mortality were compounded in those who received blood products contaminated with HIV, or hepatitis B and C. Psychiatrists who practice psychosomatic medicine should expect to encounter patients with the above problems, as they are frequently seen in medical settings. Finally, most of the commonly used psychotropic medications have uncommon but potentially important hematologic side effects or may interact with the anticoagulants used in medically ill patients.

Abstract
Depression is common in patients with end-stage renal disease and has been linked to increased mortality. Screening for depression in the general medical population remains controversial; however, given the high prevalence of depression and its significant impact on morbidity and mortality, a strong case for depression screening in patients with end-stage renal disease can be made. Several studies have been performed to validate the more common depression screening measures in patients with chronic kidney disease. The Beck Depression Inventory, the Hamilton Rating Scale for Depression, the Nine-Question Patient Health Questionnaire, and the Center for Epidemiologic Studies Depression Scale are some of the measures that have been used to screen for depression in patients with end-stage renal disease. Data suggest a higher Beck Depression Inventory cutoff score, of >14 to 16, will have increased positive predictive value at diagnosing depression in patients with end-stage renal disease. There are limited data on the treatment of depression in this patient population. Pharmacotherapy, including selective serotonin reuptake inhibitors, can be used if deemed clinically indicated, and no active contraindication exists. There are even fewer data to support the role of cognitive behavioral therapy, social support group interventions, and electroconvulsive therapy for treatment of depression in patients with chronic kidney disease. Larger randomized, controlled clinical trials aimed at the treatment of depression in patients with end-stage renal disease are desperately needed.

Abstract
OBJECTIVES To examine the available scientific literature for answers to clinically relevant questions regarding the effectiveness and tolerability of antidepressant drugs (ADs) for the acute phase treatment of depression and to assess the degree to which the literature supports the findings. METHODS We used several sources to identify primary reviews: MEDLINE (1955 to April 2006), EMBASE (1980 to April 2006), PsycINFO (1980 to April 2006), and the Cochrane Library 2006 Issue 1. Additional searches were also carried out on the following databases of the National Health Service Centre for Reviews and Dissemination: Abstracts of Reviews of Effects, Health Technology Assessment, and Turning Research into Practice. We also searched the National Institute of Health and Clinical Excellence guidance website. We carried out a metareview of selected high-quality systematic reviews of short-term pharmacologic interventions with ADs for major depression. To assess efficacy, we followed the hierarchy of evidence proposed by the Centre for Evidence Based Medicine (Oxford), including only reviews of randomized controlled trials. To assess tolerability, we also considered observational data when randomized evidence was not available. RESULTS There was randomized evidence that ADs are efficacious in primary care settings and that there may be small, but clinically important, differences in efficacy between ADs. There was no good evidence that an AD combined with an antipsychotic is superior to AD monotherapy in cases of psychotic depression or that intravenous administration leads to more rapid response. There was evidence that monoamine oxidase inhibitors are superior to tricyclic antidepressants, but not to selective serotonin reuptake inhibitors (SSRIs), in treating atypical depression. There is some evidence of harm related to the use of SSRIs in pregnancy but not to their use when breastfeeding. There is evidence that SSRIs may increase suicidal thoughts, but not actual suicide, in early-phase therapy. CONCLUSIONS We found a substantial body of evidence regarding the benefits and harms of ADs in the treatment of depressive disorder. Nonetheless, there remains considerable residual uncertainty. The evidence is inadequate for generally applicable recommendations; in most cases, the balance between risks and benefits will need to be considered for individual patients. Clinicians should also be guided by the recommendations and warnings issued by drug regulatory authorities.
