ABSTRACT
Background: Despite the anticipated efficacy of escitalopram in treating depression and anxiety in individuals with preexisting cardiovascular conditions, persistent concerns regarding its adverse effects have emerged. In this systematic review, we aimed to evaluate the cardiovascular safety profile of escitalopram compared with that of placebo in patients with underlying cardiovascular disease. Methods: We used a predefined search strategy in PubMed, Cochrane Central Register of Controlled Trials, Embase, International Clinical Trials Registry Platform, and ClinicalTrials.gov to identify studies evaluating adverse cardiovascular reactions to escitalopram in patients with underlying cardiovascular disease. Randomized controlled trials (RCTs) that provided results on cardiovascular safety outcomes were included. Two independent reviewers screened the abstracts and full texts of the individual studies. The risk of bias was assessed using version 2 of the Cochrane risk-of-bias tool for randomized trials. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Results: The primary outcomes were the frequency of major adverse cardiovascular events (MACE), QTc prolongation, and discontinuation of study medication. We identified 5 RCTs with 773 participants who met the inclusion criteria. Escitalopram was not associated with significantly increased risk of MACE (risk ratio [RR] = 1.85; 95% confidence interval [CI] 0.80 to 4.26; I2 0%; 5 RCTs; n = 773, moderate certainty of evidence), discontinuation of study medication (RR = 1.03; 95% CI 0.84-1.26; I2 0%; 5 RCTs; n = 773, low certainty of evidence), and QTc prolongation (RR = 1.20; 95% CI 0.76-1.90; I2 0%; 4 RCTs; n = 646, low certainty of evidence). Conclusion: Escitalopram does not significantly increase the risk of cardiovascular adverse reactions compared with placebo in patients with underlying cardiovascular disease. However, the presence of wide CIs and the limited number of included studies highlight the need for further studies with larger sample sizes to enhance the precision and reliability of these findings.Systematic review registration: International Prospective Register of Systematic Reviews [CRD42022298181].
ABSTRACT
OBJECTIVE: This study aimed to compare the effect of continuing and discontinuing medications on quality of life of patients with attention-deficit/hyperactivity disorder (ADHD). DATA SOURCES: PubMed, Cochrane Library, and Embase databases were searched using generic terms for ADHD, discontinuing, continuing, pharmacotherapy, and randomized controlled trials without date or language restrictions. STUDY SELECTION: Of the 3,672 screened studies, 9 met the predefined inclusion criteria on patients with ADHD; 5 of these 9 studies reporting on 1,463 patients (children and adolescents, n = 894; adults, n = 569) measured quality of life and were included in this meta-analysis. Only randomized, double-blind, placebo-controlled withdrawal trials of ADHD medications were included. DATA EXTRACTION: Data were independently extracted according to the Cochrane Handbook for Systematic Reviews of Interventions. Analyses were based on random-effects models. RESULTS: Compared with continuing medications, discontinuing them significantly worsened quality of life score in patients with ADHD (standardized mean difference [SMD] = 0.19; 95% CI, 0.08 to 0.30]). Moreover, discontinuing medications worsened this score in children and adolescents with ADHD (SMD = 0.21; 95% CI, 0.06 to 0.36) but not in adults with ADHD (SMD = 0.02; 95% CI, -0.46 to 0.50). CONCLUSIONS: Discontinuing medications was associated with a small but statistically significant decrease in quality of life among children and adolescents with ADHD but not in adults with ADHD. Quality of life can be applied in pharmacologic interventions regarding continuing and discontinuing medication because this concept is related to individuals' appraisal of their situation. Quality of life is an important factor for planning individualized ADHD medication treatment.
