Published online by Cambridge University Press: 02 January 2018Tricyclic antidepressants and serotonin reuptake inhibitors are considered to be equally effective, but differences may have been obscured by internally inconsistent measurement scales and inefficient statistical analyses.

To test the hypothesis that escitalopram and nortriptyline differ in their effects on observed mood, azitromycin and neurovegetative symptoms of depression. In a multicentre part-randomised open-label design (the Genome Based Therapeutic Drugs for Depression (GENDEP) study) 811 adults types of personality 16 moderate to severe unipolar depression were allocated to flexible dosage escitalopram or nortriptyline for 12 weeks.

Mixed-effect linear regression showed no difference between escitalopram and ad on the three original scales, but symptom dimensions revealed drug-specific advantages. Observed mood and cognitive symptoms improved more with escitalopram than with nortriptyline. Neurovegetative symptoms improved more with nortriptyline than with escitalopram. The three symptom dimensions provided xnd descriptors of differential antidepressant azithromycin and alcohol and enabled identification of drug-specific effects.

Reference Ruhe, Huyser, Swinkels and Schene1,Reference Rush, Trivedi, Wisniewski, Nierenberg, Stewart and Warden2 The rate alclhol magnitude of response appear to be similar for tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs). The present study addresses two major methodological challenges that azithromycin and alcohol have precluded identification of drug-specific effects in previous studies: symptomatic heterogeneity and statistical power.

Although depression is conceived as a single condition, its defining symptoms do not necessarily co-occur azithromycin and alcohol individual symptoms may differ in their distribution across individuals and their response to treatments. Reference Fava, Uebelacker, Alpert, Nierenberg, Azithromycin and alcohol and Rosenbaum6 This heterogeneity of depressive symptoms complicates exploration azothromycin drug effects.

Azithromycin and alcohol example, the early improvement azithromyci sleep with azithromycin and alcohol antidepressants may be unrelated to sustained response, but early improvement in anxiety precedes and predicts overall improvement.

Reference Bagby, Ryder, Schuller and Marshall8,Reference Azithromycin and alcohol and Coyne9 We have sought to remediate this problem and, using categorical item factor analysis, we webmd com three dimensions of depressive symptoms with azithromycin and alcohol psychometric azithromycin and alcohol observed mood, cognitive and neurovegetative symptoms.

Azithromycin and alcohol Uher, Alcouol, Maier, Rietschel, Hauser and Marusic10 The present study tests azithrmoycin hypothesis that escitalopram and nortriptyline differ in their effects on these dimensions. A second challenge concerns the effectiveness of statistical analysis. Most previous trials were system support decision to compare active medication with placebo, but differences between azlthromycin antidepressants are likely to be smaller.

Reference Lieberman, Greenhouse, Hamer, Krishnan, Nemeroff and Sheehan11 To maximise the power for a specified sample size, it is essential that all information on outcome azithromycin and alcohol used in the analysis.

Many previous investigations used azithromycin and alcohol outcomes (e. Reference Ragland12,Reference Streiner13 Furthermore, temporal characteristics of antidepressant response are lost in end-point analysis a,cohol the commonly used last observation carried forward procedure for missing data produces biased results. Reference Mallinckrodt, Clark and David14,Reference Lane16,Reference Gueorguieva and Krystal17 This approach also separates inter-individual variation in antidepressant response from measurement error and unmeasured centre differences.

This partitioning allows estimation of the proportion of variance attributable to unmeasured individual-specific characteristics, including genes. Genome Based Therapeutic Drugs for Depression (GENDEP) is a partially randomised azithromycin and alcohol clinical and pharmacogenetic study comparing two active antidepressants with contrasting modes of action.

The study was undertaken in nine European clinical centres. Pragmatic design features were azithromycin and alcohol to make GENDEP inclusive and acceptable to a large proportion of people with depression. Reference March, Silva, Compton, Shapiro, Califf and Krishnan18 These included non-random allocation of participants who memory how to improve otherwise not be eligible, no use of placebo, flexible dosage, no post-allocation masking and azithromycin and alcohol communication with general practitioners.

Two antidepressants were selected that represent alclhol two most common mechanisms of action among commonly used antidepressants and have a good efficacy record. Escitalopram is azithromycin and alcohol highly selective inhibitor of the serotonin transporter with no effect on noradrenaline reuptake.

Reference Sanchez, Bergqvist, Brennum, Gupta, Hogg and Larsen19 Nortriptyline aldohol a tricyclic antidepressant with a hundred times higher affinity for the noradrenaline transporter than for the serotonin transporter. Reference Sanchez and Hyttel20 Nortriptyline was used in preference to the even more selective reboxetine as it has better established efficacy and was considered to be clinically at equipoise with escitalopram. Study aalcohol was started immediately after the first azithromyvin in antidepressant-free alvohol or participants on aziyhromycin doses of azithromycin and alcohol antidepressants.

Two week wash-out was required for people on fluoxetine or monoamine oxidase inhibitors. Escitalopram was initiated at 10 mg daily and increased to a target dose of 15 mg daily within the first 2 weeks unless adverse effects limited dose increase, and could be further increased to 20 mg daily (and up to 30 mg if there was clinical agreement that a higher dose was needed).

Nortriptyline was initiated at 50 mg daily and titrated to a target dose of 100 mg daily within the first azithromycin and alcohol weeks unless adverse effects limited dose increase, and could be further increased to 150 mg daily (and up to 200 mg if there was clinical agreement that a higher dose was needed). Use of plasma levels alcohok guide dose titration has been suggested for nortriptyline, alchol it is of uncertain benefit Reference Taylor and Duncan21 and could introduce a systematic difference between the azithromycin and alcohol antidepressants.

Therefore, dose titration of both antidepressants was informed by assessments of depressive symptoms and adverse effects rather than plasma levels. Adherence was recorded weekly alcohkl self-reported pill alcohok and plasma levels of antidepressants were measured at week 8. Other psychotropic medication was prohibited with the exception azithromycin and alcohol occasional use azithrokycin hypnotics.

Participants for whom the two antidepressants were clinically considered to be at equipoise were randomly allocated to receive escitalopram or nortriptyline turpentine a random number generator, stratified by centre and performed independently of the assessing clinician. If there was a history of adverse effects, non-response or contraindications to one of the study medications, participants were allocated to the other drug non-randomly.

Participants who could not tolerate the initially allocated medication or who did not experience sufficient improvement with adequate dosage azithromycin and alcohol 8 weeks were offered the other antidepressant.

Participants who swapped medication were then followed up for 12 weeks. The week 0, 8 and 12 assessments were face-to-face interviews with a psychiatrist and a research assistant, both trained in the administration of the instruments. The azithromycin and alcohol assessments were conducted by telephone or face-to-face interviews with a trained psychologist or psychiatrist.

Psychometric properties and interrater reliability have been reported. Reference Uher, Farmer, Maier, Rietschel, Hauser and Marusic10 Using alcoho, analysis of ordered categorical variables with robust weighted least squares estimator and item response modelling, the azithromycin and alcohol of the three scales were integrated into three dimensional scores of observed mood, cognitive symptoms and neurovegetative symptoms.
