OBJECTIVE The purpose of this study was to examine the use of benzodiazepines ( BZs ) and selective serotonin reuptake inhibitors/selective norepinephrine reuptake inhibitors ( SSRIs/SNRIs ) over nine years of follow-up in middle-aged and older adults with diagnoses of panic disorder with or without agoraphobia , social phobia , or generalized anxiety disorder . SETTING AND PARTICIPANTS Participants in this study were enrolled in the Harvard/Brown Anxiety Research Project ( HARP ) . HARP is a naturalistic , longitudinal , multisite study of adults with anxiety disorders who are recruited from psychiatric setting s. The analytic sample consisted of 51 participants with anxiety disorders who were 55 to 70 years old at baseline and a younger cohort of 211 participants added for comparative analysis . DESIGN The authors examined patterns of medication use ( BZs and SSRIs/SNRIs ) in participants with anxiety disorders as they aged , by assessing the proportion of participants taking these medications using generalized estimating equation modeling . MEASUREMENTS The present data were derived from the structured diagnostic interview administered at enrollment using a combination of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders , Third Edition-R Non-Affective Disorder , Patient Version , Research Diagnostic Criteria Schedule for Affective Disorders-Lifetime , and subsequent follow-up interviews over a nine-year period using the Longitudinal Interval Follow-up Evaluation-Pharmacia & Upjohn to assess the weekly course of disorders to indicate syndrome severity and document medication use by specific type and dose on a weekly basis . RESULTS Findings showed that rates of BZ use were high among both the older ( 53 % at baseline ) and the younger ( 57.4 % ) age groups and did not significantly decrease over time , after controlling for time in episode of their anxiety disorders . There was a statistically significant increase in  SSRI/SNRI use over time in both groups . At the beginning of the study , 18 % of the older group and 21 % of the younger group were using SSRIs/SNRIs ; however , at the end of the study , the rates increased to 35 % and 43 % , respectively . CONCLUSIONS Although there was an increase in  SSRI/SNRI use in older participants with anxiety disorders over the course of study , at nine years of follow-up , only 35 % of participants were utilizing SSRI/SNRI medication , while more than one-half of the same participants were continuing to use BZs . To the authors ' knowledge , there are no r and omized clinical trials that have addressed comparative efficacy and safety of BZs and SSRIs/SNRIs in this population . However , there is documented evidence of adverse effects of chronic BZ use and the risk of developing dependency in older population OBJECTIVE This study evaluated time to response in the treatment of panic disorder with a selective serotonin reuptake inhibitor ( SSRI ) or serotonin norepinephrine reuptake inhibitor ( SNRI ) combined with alprazolam orally disintegrating tablets ( ODT ) , or SSRI/SNRI alone . DESIGN Subjects were r and omized to eight weeks open-label treatment with alprazolam ODT ( 4 weeks treatment followed by 3 - 4 week taper ) combined with an SSRI or SNRI , or treatment with SSRI/SNRI alone . SETTING The study was conducted under naturalistic conditions at 62 primary care and 34 psychiatric practice s. PARTICIPANTS Male or female subjects ≥18 years of age diagnosed with panic disorder , with or without agoraphobia . MEASUREMENTS The primary efficacy measure was time to response , defined as ≥50-percent decrease from baseline Hamilton Rating Scale for Anxiety ( HAM-A ) total score . Secondary measures included change from baseline in HAM-A scores and the Clinical Global Impression of Improvement ( CGI-I ) and Patient Global Impression ( PGI ) scales . RESULTS The intent-to-treat ( ITT ) population comprised 245 subjects . There was no statistical difference between treatment groups in time to response in the ITT population ; however , a prospect ively defined per protocol analysis revealed a statistically significant earlier onset of effect in subjects receiving SSRI/SNRI plus alprazolam ODT ( P<0.05 ) . Mean change from baseline in HAM-A total score and clinician and patient measures of global improvement also showed statistically significant early advantages for combination therapy compared with SSRI/SNRI monotherapy . CONCLUSION Combined treatment of panic disorder with alprazolam ODT and an SSRI/SNRI may be associated with more rapid improvement in anxiety symptoms compared with an SSRI/SNRI alone Objective This r and omised , double-blind , 12-week study compared efficacy and tolerability of flexible-dose treatment with vortioxetine ( 10–20 mg/day ) versus agomelatine ( 25–50 mg/day ) in major depressive disorder patients with inadequate response to selective serotonin reuptake inhibitor (SSRI)/serotonin – noradrenaline reuptake inhibitor ( SNRI ) monotherapy . Methods Patients were switched directly from SSRI/SNRI to vortioxetine or agomelatine . Primary endpoint was change from baseline to week 8 in the Montgomery – Åsberg Depression Rating Scale ( MADRS ) total score analysed by mixed model for repeated measurements , using a noninferiority test followed by a superiority test . Secondary endpoints included response and remission rates , anxiety symptoms ( Hamilton Anxiety Rating Scale ) , Clinical Global Impression , overall functioning ( Sheehan Disability Scale ) , health-related quality of life ( EuroQol 5 Dimensions ) , productivity ( work limitation question naire ) and family functioning ( Depression and Family Functioning Scale ) . Results Primary endpoint noninferiority was established and vortioxetine ( n = 252 ) was superior to agomelatine ( n = 241 ) by 2.2 MADRS points ( p < 0.01 ) . Vortioxetine was also significantly superior in response and remission rates at weeks 8 and 12 ; MADRS , Hamilton Anxiety Rating Scale , Clinical Global Impression , Sheehan Disability Scale and EuroQol 5 Dimensions scores at week 4 onwards ; work limitation question naire at week 8 and Depression and Family Functioning Scale at weeks 8 and 12 . Fewer patients withdrew because of adverse events with vortioxetine ( 5.9 % vs 9.5 % ) . Adverse events ( incidence ≥5 % ) were nausea , headache , dizziness and somnolence . Conclusions Vortioxetine was noninferior and significantly superior to agomelatine in major depressive disorder patients with previous inadequate response to a single course of SSRI/SNRI monotherapy . Vortioxetine was safe and well tolerated The objective of this study was to assess the efficacy of sertraline in migraine prophylaxis . Other selective serotonin reuptake inhibitors have been studied for migraine prophylaxis , but this is the first report with sertraline .  Twenty-seven subjects were enrolled and baseline assessment of migraine frequency and severity were measured over a 4-week period . Subjects were then r and omized to receive placebo or sertraline in a double-blind fashion with headache frequency and severity measured over an 8-week period . Subjects completed a daily diary reporting the occurrence , severity , and degree of impairment associated with migraine . The headache index , a composite measure of migraine frequency and severity , scores did not significantly improve between assessment s at baseline ( 20.8 + /- 14.88 ) , 8 weeks ( 17.6 + /- 12.27 ) , and 12 weeks ( 16.7 + /- 6.38 ) in the treatment group ( n=6 ) ( P=0.956 ) . This finding is compared to other studies with the serotonin selective reuptake inhibitors , fluoxetine , fluvoxamine , and paroxetine . The authors believe that the selective serotonin reuptake inhibitors are not as effective as conventional migraine prophylaxis medications such as beta-blockers , tricyclic antidepressants , or divalproex sodium , but that in patients with comorbid depression who have failed conventional therapy selective serotonin reuptake inhibitors may be effective In this report , which is an up date of a guideline published in 2002 ( B and elow et al. 2002 , World J Biol Psychiatry 3:171 ) , recommendations for the pharmacological treatment of anxiety disorder , obsessive-compulsive disorder ( OCD ) and post-traumatic stress disorder ( PTSD ) are presented . Since the publication of the first version of this guideline , a substantial number of new r and omized controlled studies of anxiolytics have been published . In particular , more relapse prevention studies are now available that show sustained efficacy of anxiolytic drugs . The recommendations , developed by the World Federation of Societies of Biological Psychiatry ( WFSBP ) Task Force for the Pharmacological Treatment of Anxiety , Obsessive-Compulsive and Post-traumatic Stress Disorders , a consensus panel of 30 international experts , are now based on 510 published r and omized , placebo- or comparator-controlled clinical studies ( RCTs ) and 130 open studies and case reports . First-line treatments for these disorders are selective serotonin reuptake inhibitors ( SSRIs ) , serotonin-noradrenaline reuptake inhibitors ( SNRIs ) and the calcium channel modulator pregabalin . Tricyclic antidepressants ( TCAs ) are equally effective for some disorders , but many are less well tolerated than the SSRIs/SNRIs . In treatment-resistant cases , benzodiazepines may be used when the patient does not have a history of substance abuse disorders . Potential treatment options for patients unresponsive to st and ard treatments are described in this overview . Although these guidelines focus on medications , non-pharmacological were also considered . Cognitive behavioural therapy ( CBT ) and other variants of behaviour therapy have been sufficiently investigated in controlled studies in patients with anxiety disorders , OCD , and PTSD to support them being recommended either alone or in combination with the above medicines Objective : Hot flashes are a major quality -of-life issue for breast cancer survivors , interrupting sleep , reducing quality of life , and diminishing treatment adherence to adjuvant endocrine therapies . Serotonin-norepinephrine reuptake inhibitors ( SNRIs ) and selective serotonin reuptake inhibitors ( SSRIs ) are used widely but are only partially effective for hot flashes . Alternative strategies are needed . We hypothesized that augmentation of SSRI/SNRI therapy with hypnotic agents would optimize hot flash therapy by improving sleep and quality of life . Methods : Women with breast cancer or at high risk for developing the disease who had hot flashes in association with nocturnal awakenings were r and omized to double-blinded treatment with zolpidem 10 mg or placebo for 5 weeks .  SSRI/SNRI nonusers ( 81 % ) started venlafaxine XR 75 mg/day concurrently , whereas SSRI/SNRI users continued that therapy . We compared the proportion of responders , defined as study completers with improved subjective sleep quality ( Pittsburgh Sleep Quality Index ) and /or objective ly assessed wake time after sleep onset on actigraphy , between groups . Results : Of 53 women ( aged 51 ± 8 y ) r and omized to zolpidem augmentation ( n = 25 ) or placebo augmentation ( n = 28 ) , 38 completed the protocol ( 57 % on placebo , 88 % on zolpidem ) . More women augmented with zolpidem than placebo were responders on the sleep outcome ( 40 % vs 14 % ; P = 0.035 ) . Quality of life improved more with zolpidem than with placebo ( P = 0.01 ) . Treatment effects on hot flashes and mood did not differ between groups . Conclusions : Augmentation of SSRI/SNRI with zolpidem improves sleep and quality of life in breast cancer survivors with hot flashes and associated sleep disturbance . Adding a hypnotic agent to an SSRI/SNRI helps women to sleep through nighttime hot flashes . Treatments targeting sleep may be an important supplemental strategy to optimize well-being OBJECTIVES : Although the tricyclic antidepressant amitriptyline is extensively used in the prophylactic treatment of chronic tension-type headache , only few studies have investigated the efficacy of this treatment and the results are contradictory . In addition , the new selective serotonin reuptake inhibiting antidepressants , which are widely used in depression and of potential value in pain management , have never been investigated in a placebo controlled study of tension-type headache . The aim was to evaluate the efficacy of amitriptyline and of the selective serotonin reuptake inhibitor citalopram in chronic tension-type headache . METHODS : Forty non-depressed patients with chronic tension type headache were included in a 32 week , double blind , placebo controlled , three-way crossover study . RESULTS : Thirty four patients completed the trial .  Amitriptyline reduced area under the headache curve by 30 % compared with placebo ( P = 0.002 ) , whereas citalopram had no significant effect ( P = 0.68 ) . Explanatory analyses showed that amitriptyline significantly reduced the duration of headache ( P = 0.01 ) , headache frequency ( P = 0.01 ) , and intake of analgesics ( P = 0.02 ) but not headache intensity ( P = 0.12 ) . CONCLUSION : Although amitriptyline did not eliminate the headache , it provided a clinical ly important reduction of headache in the majority of otherwise treatment resistant patients . The differential effect of amitriptyline and citalopram indicates that mechanisms other than inhibition of serotonin reuptake are involved in the analgesic effect of the tricyclic antidepressants . Amitriptyline , but not citalopram , is valuable in the prophylactic treatment of chronic tension type headache Attempts have been made to find appropriate drug regimens to treat binge eating disorder ( BED ) . Several reports have examined the use of selective serotonin reuptake inhibitors ( SSRIs ) or mood stabilizers ; both serotonin and noradrenalin reuptake inhibitors ( SNRIs ) have been reported to be useful for binge eating , but the available data are limited . We evaluated the efficacy of duloxetine , an SNRI , in 45 obese patients who reported binge eating Objective : The alpha 2A-adrenergic receptor ( ADRA2A ) plays a central role in the regulation of systemic sympathetic activity . Recently , the functional defect of ADRA2A has been implicated as a cause of depression , attention deficit hyperactivity disorder , and Tourette syndrome . In this study , the effect of genetic variants of the ADRA2A gene on the response to selective serotonin reuptake inhibitors (SSRIs)/serotonin norepinephrine reuptake inhibitors ( SNRIs ) was examined in depressed patients . Method : Ninety-three Japanese depressed patients were recruited in the present study , assigned r and omly to paroxetine or milnacipran , and assessed by the Hamilton Rating Scale for Depression ( HAM-D ) scoring every 2 weeks before and after drug administration . The ADRA2A C-1297 G polymorphism was considered in the association analysis with the efficacy of antidepressants . Results : There were significant differences in the HAM-D percent score change over time ( P = 0.019 ) among C/C , C/G , and G/G of the ADRA2A C-1297 G polymorphism in the total subjects . The C allele carriers of the ADRA2A C-1297 G polymorphism showed a significantly better improvement than G/G subjects at weeks 2 , 4 , and over time ( P = 0.037 ) in the milnacipran group . Discussion : Our findings suggest that ADRA2A plays an important role in depression therapy . The level of ADRA2A expression could be associated with the efficacy of SSRIs/SNRIs , especially milnacipran , although the functional change brought about by C-1297 G polymorphism has not yet been fully identified in vivo and in vitro . Conclusions : The ADRA2A polymorphism could be a reasonable c and i date to predict the response to milnacipran . Our results are still preliminary , and a large sample size will be required to confirm our findings . However , to the best of our knowledge , this study is the first to suggest a possible association of ADRA2A variants with the SNRI response & NA ; The tricyclic antidepressant amitriptyline is the only documented and most widely used prophylactic drug for  chronic tension‐type headache ( CTTH ) . However , it is not fully clarified whether the serotonin ( 5‐HT ) reuptake inhibition plays a major role for the analgesic effect of amitriptyline . To explore the importance of 5‐HT reuptake inhibition for mechanism of action of the analgesic effect of amitriptyline we investigated platelet 5‐HT levels during preventive treatment of CTTH with amitriptyline , the selective serotonin reuptake inhibitor citalopram , and placebo .  Thirty‐four patients with CTTH were given preventive treatment with amitriptyline 75 mg/day , the selective 5‐HT reuptake inhibitor citalopram 20 mg/day , and placebo in a 32‐week , double‐blind , placebo‐controlled , three‐way crossover trial . Blood sample s were collected in the last week of each treatment period . Platelet 5‐HT was used as a measure of 5‐HT reuptake inhibition and determined by high performance liquid chromatography . Area under the headache curve was 308 ( 157–715 ) ( median with quartiles in parentheses ) with amitriptyline and significantly lower than 377 ( 158–1121 ) with citalopram ( P=0.04 ) , and 441 ( 178–1408 ) with placebo ( P=0.002 ) . There was no difference between citalopram and placebo ( P=0.23 ) . Platelet 5‐HT was 0.4 (0.3–0.7) × 10−18 mol/platelet with citalopram , which was significantly lower than 1.7 (1.2–2.4) × 10−18 mol/platelet with amitriptyline ( P<0.001 ) , and 3.5 (2.8–4.3) × 10−18 mol/platelet with placebo ( P<0.001 ) . The lower platelet 5‐HT during treatment with citalopram than amitriptyline indicates that 5‐HT reuptake was most effectively inhibited by citalopram . In contrast , amitriptyline was most effective in reduction of headache . This suggests that the analgesic effect of amitriptyline in CTTH is not solely due to 5‐HT reuptake inhibition and that other mechanisms such as norepinephrine reuptake inhibition , NMDA receptor antagonism , blockade of muscarinic receptors and ion channels should be addressed in the future research Some evidence suggests that medications that modulate both serotonin and norepinephrine may be more effective than selective serotonin-reuptake inhibitors ( SSRIs ) in severe major depressive disorder ( MDD ) . This prospect i ve pragmatic trial tests this hypothesis . Patients with severe MDD were r and omly assigned to either duloxetine ( a serotonin and norepinephrine-reuptake inhibitor ) or physicians ’ choice of four generic SSRIs . Nonblinded , flexibly dosed treatment was used to mimic clinical practice . To address potential investigator bias , the patient-reported Quick Inventory of Depressive Symptomatology Self-Report ( QIDS-SR ) was used as the primary efficacy outcome measure . A total of 750 out patients ( 19.2 % , African descent ; 14.8 % , Hispanic ) were r and omized . The primary outcome , remission at week 12 by QIDS-SR , was numerically greater for duloxetine compared with SSRIs ( 36 vs. 32 % ) , but this difference was not statistically significant . Mean changes in secondary outcomes were significantly superior in favor of duloxetine for the Hamilton Depression Scale-17 item , the Brief Pain Inventory , and the Sheehan Disability Scale . Remission superiority on the QIDS-SR was not achieved . Significantly greater benefit for duloxetine compared with SSRIs was demonstrated on measures of pain and functioning . Study demographics suggest a more generalizable racial and ethnic population than is typical in r and omized clinical trials BACKGROUND This r and omized , open-label , rater-blinded , multicenter study compared treatment outcomes with the serotonin-norepinephrine reuptake inhibitor ( SNRI ) venlafaxine extended release ( ER ) with selective serotonin reuptake inhibitors ( SSRIs ) in primary care patients with major depressive disorder . METHOD Study data were collected from November 29 , 2000 , to March 4 , 2003 . Out patients who met diagnostic criteria for major depressive disorder according to the Mental Health Screener , a computer-administered telephone interview program that screens for the most common mental disorders , and had a total score on the 17-item Hamilton Depression Rating Scale ( HDRS(17 ) ) ≥ 20 were r and omly assigned to receive up to 6 months of open-label venlafaxine ER 75 - 225 mg/d ( n = 688 ) or an SSRI ( n = 697 ) : fluoxetine 20 - 80 mg/d , paroxetine 20 - 50 mg/d , citalopram 20 - 40 mg/d , and sertraline 50 - 200 mg/d . The primary outcome was remission ( HDRS(17 ) score ≤ 7 ) at study end point using the last-observation-carried-forward method to account for early termination . A mixed-effects model for repeated measures ( MMRM ) analysis evaluated secondary outcome measures . RESULTS Fifty-one percent of patients completed the study . Month 6 remission rates did not differ significantly for venlafaxine ER and the SSRIs ( 35.5 % vs 32.0 % , respectively ; P = .195 ) . The MMRM analysis of HDRS(17 ) scores also did not differ significantly ( P = .0538 ) . Significant treatment effects favoring the venlafaxine ER group were observed for remission rates at days 30 , 60 , 90 , and 135 and a survival analysis of time to remission ( P = .006 ) , as well as Clinical Global Impressions-severity of illness scale ( P = .0002 ) ; Hospital Anxiety and Depression Scale-Anxiety subscale ( P = .03 ) ; 6-item Hamilton Depression Rating Scale , Bech version ( P = .009 ) ; and Quick Inventory of Depressive Symptomatology-Self-Report ( P = .0003 ) . CONCLUSIONS Remission rates for patients treated with venlafaxine ER or an SSRI did not differ significantly after 6 months of treatment . Results of most secondary analyses suggested that SNRI treatment had a greater antidepressant effect versus the SSRIs studied Patients with major depressive disorder ( MDD ) usually suffer from altered cognitive functions of episodic memory , working memory , mental processing speed and motor response . Diverse studies suggest that different antidepressant agents may improve cognitive functions in patients with MDD . The aim of this work is to study the effects of serotonergic reuptake inhibitors ( SSRIs ) and serotonergic-noradrenergic reuptake inhibitors ( SNRIs ) treatments to improve the performance on memory tasks and mental processing speed in MDD . Seventy-three subjects meeting criteria for major depressive disorder were assessed with the Hamilton depression rating scale and a neuropsychological battery . The subjects were medicated with escitalopram ( n=36 ) or duloxetine ( n=37 ) for 24 weeks . At the end of the trial , the subjects were assessed again with the same neuropsychological battery used prior to the treatment . Both treatments improved importantly the episodic memory and to a lesser extent , working memory , mental processing speed and motor performance . Our results suggest that cognition is partially independent from improvement in clinical symptoms . Both groups achieved remission rates in the HAM-D-17 after 24 weeks of treatment , but SNRI was superior to SSRI  at improving episodic and working memory . Our work indicates that the superiority of SNRI over the SSRI  at episodic memory improvement is clinical ly relevant BACKGROUND Generalized anxiety disorder  ( GAD ) is a common and serious disease with a lifetime prevalence of 4.3 % to 5.9 % . It is underdiagnosed in primary care . METHODS Recommendations on the treatment of GAD are given on the basis of all available findings from pertinent r and omized trials , retrieved by a selective search of the literature . RESULTS Among psychotherapeutic techniques , various kinds of cognitive behavioral therapy ( CBT ) have been found useful in controlled trials . The drugs of first choice include selective serotonin reuptake inhibitors ( SSRIs ) , serotonin-norepinephine reuptake inhibitors ( SNRIs ) , and the calcium-channel modulator pregabalin . Tricyclic antidepressants are also effective but have more adverse effects than SSRIs . Although benzodiazepines are effective anxiolytic agents for short-term use , they should not be given over the long term because of the danger of addiction . Buspirone , an azapirone , was found to be effective in a small number of trials , but the findings across trials are inconsistent . The response rate of GAD to CBT in published studies lies between 47 % and 75 % , while its response rate to drug treatment lies between 44 % and 81 % . CONCLUSION The treatment of GAD with CBT and drugs is evidence -based and has a good chance of improving the manifestations of the disorder Abstract Safety and tolerability are important considerations when selecting patients ’ treatment for major depressive disorder . We report the long-term safety and tolerability of the nicotinic channel modulator dexmecamylamine ( TC-5214 ) , adjunct to selective serotonin reuptake inhibitors (SSRIs)/serotonin-norepinephrine reuptake inhibitors ( SNRIs ) in patients with major depressive disorder and who had an inadequate response to antidepressants . This 52-week , double-blind , placebo-controlled study explored the long-term safety and tolerability of dexmecamylamine .  Patients were r and omized 3:1 to receive flexibly dosed dexmecamylamine 1 to 4 mg adjunct to SSRI/SNRI or placebo plus SSRI/SNRI . The patient population comprised inadequate responders from 2 Phase III acute  dexmecamylamine  studies ( NCT01157078 [ study 002 ] , NCT01153347 [ study 004 ] ) and de novo patients who responded inadequately during a 6-week open-label antidepressant treatment period preceding r and omization .  Safety and tolerability were assessed by monitoring adverse events , vital signs , and physical and laboratory parameters . Descriptive statistical analyses were performed on most efficacy-related end points . Sustained efficacy was analyzed using logistic regression . Overall , 813 patients were r and omized ( 610 received dexmecamylamine , 203 received placebo ) . In total , 82.4 % and 84.6 % of patients , respectively , experienced an adverse event . Adverse events occurring more frequently with dexmecamylamine vs placebo were constipation ( 19.6 % vs 6.0 % ) , dizziness ( 12.0 % vs 7.0 % ) , and dry mouth ( 9.7 % vs 5.0 % ) . Back pain ( 2.8 % vs 8.5 % ) , weight increase ( 4.4 % vs 7.0 % ) , and fatigue ( 5.6 % vs 7.5 % ) occurred more frequently in placebo-treated patients . No notable differences were observed between dexmecamylamine and placebo for any secondary end point . In this long-term study , safety and tolerability of dexmecamylamine were consistent with that reported in acute Phase III studies of dexmecamylamine Background The US Food and Drug Administration ’s meta-analyses of placebo-controlled antidepressant trials found approximately twice the rate of suicidal behaviors among children and adults aged 24 years and younger who were r and omized to receive antidepressant medication  than among those who were r and omized to placebo .  Rates of suicidal behavior were similar for subjects aged 25–64 years whether they received antidepressants or placebo , and subjects aged 65 years or older r and omized to antidepressants were found to have lower rates of suicidal behavior . The age-stratified FDA meta-analyses did not have adequate power to investigate rates of suicidal behaviors by antidepressant drug class . Objective Our objective was to assess the risk of deliberate self-harm associated with the two most commonly prescribed classes of antidepressant agents . Design Propensity score matched cohort study of incident users of antidepressant agents . Setting Population -based healthcare utilization data of US residents . Patients US residents aged 10–64 years with a recorded diagnosis of depression who initiated use of selective serotonin reuptake inhibitors ( SSRIs ) or serotonin norepinephrine reuptake inhibitors ( SNRIs ) between 1 January 1998 and 31 December 2010.Main Outcome Measures ICD-9 external cause of injury codes E950.x – E958.x ( deliberate self-harm ) . Results A total of 102,647 patients aged between 10 and 24 years , and 338,021 aged between 25 and 64 years , initiated therapy with antidepressants . Among 10–24 year olds , prior to propensity score matching , 75,675 initiated therapy with SSRIs and 5,344 initiated SNRIs . After matching , there were 5,344 SNRI users and 10,688 SSRI users . Among the older cohort , 36,037 SNRI users were matched to 72,028 SSRI users ( from an unmatched cohort of 225,952 SSRI initiators ) . Regardless of age cohort , patients initiating SSRIs and patients initiating SNRIs had similar rates of deliberate self-harm . Restriction to patients with no antidepressant use in the past 3 years did not alter our findings . Conclusions Our findings of similar rates of deliberate self-harm for depressed patients who initiate treatment with either an SSRI or an SNRI suggests that physicians who have decided that their patients would benefit from initiating antidepressant therapy need not weigh differential suicide risk when deciding which class of antidepressant to prescribe Objective : To evaluate the efficacy and safety of a selective serotonin reuptake inhibitor ( SSRI ) and a serotonin and norepinephrine reuptake inhibitor ( SNRI ) in the treatment of depression in Parkinson disease ( PD ) . Methods : A total of 115 subjects with PD were enrolled at 20 sites . Subjects were r and omized to receive an SSRI ( paroxetine ; n = 42 ) , an SNRI ( venlafaxine extended release [ XR ] ; n = 34 ) , or placebo ( n = 39 ) . Subjects met DSM-IV criteria for a depressive disorder , or operationally defined subsyndromal depression , and scored > 12 on the first 17 items of the Hamilton Rating Scale for Depression ( HAM-D ) . Subjects were followed for 12 weeks ( 6-week dosage adjustment , 6-week maintenance ) . Maximum daily dosages were 40 mg for paroxetine and 225 mg for venlafaxine XR . The primary outcome measure was change in the HAM-D score from baseline to week 12 . Results : Treatment effects ( relative to placebo ) , expressed as mean 12-week reductions in HAM-D score , were 6.2 points ( 97.5 % confidence interval [ CI ] 2.2 to 10.3 , p = 0.0007 ) in the paroxetine group and 4.2 points ( 97.5 % CI 0.1 to 8.4 , p = 0.02 ) in the venlafaxine XR group . No treatment effects were seen on motor function . Conclusions : Both paroxetine and venlafaxine XR significantly improved  depression in subjects with PD . Both medications were generally safe and well tolerated and did not worsen motor function . Classification of Evidence : This study provides Class I evidence that paroxetine and venlafaxine XR are effective in treating depression in patients with PD The past decade has brought major new developments in the psychopharmacologic management of generalized anxiety disorder and social phobia . We examined medication-prescribing patterns for the treatment of these anxiety disorders for 12 years to assess changes in patients ' anti-anxiety psychotropic medication usage during that period of evolving practice guidelines . We examined psychotropic medication use in 305 patients with generalized anxiety disorder and 232 with social phobia enrolled in the Harvard/Brown Anxiety Disorders Research Project ( HARP ) , a prospect i ve , longitudinal study of anxiety disorders .  Psychotropic treatment patterns seem to have remained relatively stable over 12 years with benzodiazepines the medications most commonly used for both generalized anxiety disorder and social phobia . Comparatively , selective serotonin reuptake inhibitor ( SSRI ) and venlafaxine usage as st and -alone medications for these disorders remained low throughout the follow-up period . At the 12-year follow-up , 24 % of patients with generalized anxiety disorder and 30 % of patients with social phobia were utilizing neither an  SSRI/selective norepinephrine reuptake inhibitor ( SNRI ) nor a benzodiazepine . Treatment recommendations for use of SSRIs and venlafaxine in the management of generalized anxiety disorder and social phobia initially promulgated in 1998 had a modest impact on changes in psychopharmacologic practice 4 - 5 years later . Difficulties in the implementation of treatment guidelines are discussed
Two studies compared SSRIs or SNRIs versus amitriptyline and found no evidence for a difference in terms of migraine frequency ( st and ardised mean difference ( SMD ) 0.04 , 95 % confidence interval ( CI ) -0.72 to 0.80 ; I(2 ) = 72 % ) , or other secondary outcomes such as migraine intensity and duration .SSRIs  or SNRIs were generally more tolerable than tricyclics .
Since the last version of this review , the new included studies have not added high quality evidence to support the use of SSRIs or venlafaxine as preventive drugs for migraine .
There is no evidence to consider SSRIs or venlafaxine as more effective than placebo or amitriptyline in reducing migraine frequency , intensity , and duration over two to three months of treatment .
Our conclusion is that the use of SSRIs and SNRIs for migraine prophylaxis is not supported by evidence
BACKGROUND This is an up date d version of the original Cochrane review published in 2005 on selective serotonin reuptake inhibitors ( SSRIs ) for preventing  migraine and tension-type headache .
Another up date d review is under development to cover tension-type headache .
Migraine is a common disorder .
The chronic forms are associated with disability and have a high economic impact .
In view of discoveries about the role of serotonin and other neurotransmitters in pain mechanisms , selective serotonin reuptake inhibitors ( SSRIs ) and serotonin-norepinephrine reuptake inhibitors ( SNRIs ) have been evaluated for the prevention of migraine .
OBJECTIVES To determine the efficacy and tolerability of SSRIs and SNRIs compared to placebo and other active interventions in the prevention of episodic and chronic migraine in adults .
