Use of selective serotonin and norepinephrine reuptake inhibitors (SNRIs) in the treatment of autism spectrum disorder (ASD), comorbid psychiatric disorders and ASD-associated symptoms: a clinical review
Published online by Cambridge University Press: 07 December 2020
Abstract
It is challenging to treat symptoms of autism spectrum disorder (ASD), comorbid psychiatric disorders and ASD-associated symptoms. Some of the commonly used medications to treat these can, and frequently do have serious adverse side effects. Therefore, it is important to identify medications that are effective and with fewer side effects and negative outcomes. In this review, we looked at current evidence available for using the serotonin and norepinephrine reuptake inhibitors (SNRIs) class of medications in treating some of these often difficult to treat symptoms and behaviors. An extensive literature search was conducted using EBSCO.host. Our search algorithm identified 130 articles, 6 of which were deemed to meet criteria for the purpose of this review. Each of these six articles was independently reviewed and critically appraised. As a prototype of the SNRIs family, venlafaxine was found to be a useful adjuvant in children and adults with ASD for the treatment of self-injurious behaviors, aggression, and ADHD symptoms when used in doses lower than its antidepressant dosage. However, duloxetine was not found to show any added benefit in treatment of any of the comorbid symptoms and behaviors in ASD when compared to other antidepressants. On the other hand, milnacipran was reported to produce improvements in impulsivity, hyperactivity symptoms, and social functioning through reduction of inattention of ADHD when comorbid with ASD. Overall, SNRIs were shown variable effectiveness in treatment of these comorbid symptoms and behaviors in ASD.
