A small new study from Boston University finds that taking yoga classes twice a week may help ease depression, thanks in part to deep breathing_ by [Alexandra Sifferlin](https://time.com/author/alexandra-sifferlin/) ## Alexandra Sifferlin Feb 21, 2018 11:30 PM UTC A small new study from Boston University finds that taking yoga classes twice a week may help ease depression, thanks in part to deep breathing by [Alexandra Sifferlin](https://time.com/author/alexandra-sifferlin/) ## Alexandra Sifferlin Feb 21, 2018 11:30 PM UTC Millions of people [take antidepressants](http://time.com/4900248/antidepressants-depression-more-common/) for depression. But there’s long been debate over just how effective the medications actually are. On Wednesday, a [large new study](http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2817%2932802-7/fulltext) provides evidence that antidepressants are more effective than placebo at treating acute depression in adults. The study, published in the journal [_The Lancet_](http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2817%2932802-7/fulltext), looked at the published data from 522 randomized controlled trials testing 21 different types of antidepressants. The study authors also reached out to pharmaceutical companies and study authors for additional unpublished study data. All told, the data collection included 116,477 men and women, ages 18 and older, who had depression and who were treated for at least eight weeks. The researchers found that every type of antidepressant they studied was more effective at lessening symptoms of depression over time than placebo. They considered a drug “effective” if it reduced depression symptoms by 50% or more. The researchers expected to find that some antidepressants would prove to be better than placebo, but they were surprised that every drug was more effective, says lead study author Dr. Andrea Cipriani of the University of Oxford in the UK. “We were open to any result,” he says. “This is why we can say this is the final answer to the controversy.” **MORE:** [A New Hope For Depression](http://time.com/4876098/new-hope-for-depression/) Though researchers found that every drug was more effective than placebo, some were more effective than others. The most effective were Agomelatine (sold under several brand names, including Valdoxan, Melitor and Thymanax), amitriptyline (Elavil), escitalopram (Lexapro), mirtazapine (Remeron), paroxetine (Paxil), venlafaxine (Effexor XR) and vortioxetine (Trintellix). The least effective, the study authors concluded, appeared to be Fluoxetine (Prozac), fluvoxamine (Faverin), reboxetine (Edronax) and trazodone (Desyrel). The researchers also assessed acceptability of the drug, which they did by analyzing the proportion of people who dropped out of the study before eight weeks. The only drug that was shown to be less acceptable than placebo was clomipramine. While antidepressants are a very common form of depression treatment, they aren’t perfect. [About a third of people with depression do not respond to treatment.](http://time.com/4876098/new-hope-for-depression/) When they do work, they can take four to eight weeks to kick in. But many people with depression are not even trying antidepressants or other treatments, like psychotherapy. A [recent study](https://link.springer.com/article/10.1007/s11606-017-4297-2) of more than 240,000 people found that only about a third of those who were newly diagnosed with depression got treatment. “We need to increase the number of people who are getting treated effectively,” Cipriani says. “I’m not saying all patients with depression should be treated with antidepressants—they should all be offered effective treatments.” Most of the 522 studies analyzed were funded by pharmaceutical companies, and the researchers say that 9% were rated as having a high risk of bias. Cipriani says the study design and the inclusion of unpublished data in their analysis was meant to mitigate that potential bias. The researchers were also unable to tease apart differences among groups of people in the studies—for instance, how the drugs worked for people of different ages or gender. The dataset used in the report will be publicly available so other research groups can try to replicate the findings. “This is the largest and most robust study ever in antidepressants,” says Cipriani. “and we found good news that they work, and outweigh the side effects.” ## Transcript [00:54] [ MUSIC ] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/"},"headline":"These Antidepressants Are Most Effective, Study Says","datePublished":"2018-02-21T23:30:32.000Z","dateModified":"2026-10-12T08:59:49.317Z","description":"21 antidepressants were found to be more effective than placebo","url":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/","keywords":["Mental Health/Psychology","healthytime"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt8ce6ad6dc36f7b02/6988c1414e9ee7b22aa0a594/time-health-stock-pills-empty.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alexandra Sifferlin","jobTitle":null,"url":"https://time.com/author/alexandra-sifferlin/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt8ce6ad6dc36f7b02/6988c1414e9ee7b22aa0a594/time-health-stock-pills-empty.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"time-health-stock-pills","caption":"TIME, health, stock,","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https://time.com/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"https://time.com/tag/mental-healthpsychology/","name":"Mental Health/Psychology"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/","name":"These Antidepressants Are Most Effective, Study Says"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"It's Official: Yoga Helps Depression","description":"A small new study from Boston University finds that taking yoga classes twice a week may help ease depression, thanks in part to deep breathing","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/X1gG6U73/poster.jpg?width=720","uploadDate":"2017-03-09T17:35:32.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/X1gG6U73.m3u8","embedUrl":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/","duration":"PT1M2S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/5169013/antidepressants-more-effective-placebo-treating-depression/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
