“…The 4 studies showed a positive benefit for celecoxib at some point in the trial, although the one study conducted in Germany was plagued by a dropout rate of 50% in the celecoxib group and 60% in the placebo group (Muller et al, 2006), and of the remaining 3 studies, all of which were conducted in Iran, one showed no effect at 8 weeks (Hashemian et al, 2011); yet, for unclear reasons, in each meta-analysis, the more positive 4-week data from this study (that appear in the literature as an abstract) are included in the efficacy evaluation (Muller et al, 2006;Akhondzadeh et al, 2009;Hashemian et al, 2011;Abbasi et al, 2012). Of note, the Iranian group has also published positive data for celecoxib in OCD, acute bipolar mania, and depression in breast cancer, indicating an extraordinary efficacy that warrants further evaluation (Arabzadeh et al, 2015;Mohammadinejad et al, 2015;Shalbafan et al, 2015). Finally, there are some data to support that acetylsalicylic acid may augment the response to conventional antidepressant therapy, although this is a small literature that is in need of larger studies (Mendlewicz et al, 2006).…”
