The Editor and Publisher of the Drug Design, Development and Therapy wish to retract the published article. Concerns were raised regarding the alleged duplication of images in Figure 2 with the same images from Figure 1 in Zhu et al, 2015 ‘A novel in situ gel base of deacetylase gellan gum for sustained ophthalmic drug delivery of ketotifen: in vitro and in vivo evaluation’ (https://doi.org/10.2147/DDDT.S87368).
The authors did not respond to our queries and no explanation for the alleged image duplication was provided. The Editor determined that the reported findings were unreliable and requested to retract the article. The authors were notified of this.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
