antacid using an artificial stomach model: an in vitro evaluation

Reviewer's report:
The job is very well done. 
Clear and concise work. 
However, I believe that the medication studied is currently widely used as OTC
and there is already its credibility guaranteed with the use for many decades and
that therefore is not something unheard of in terms of addition to the daily
practice of the doctor but as a pharmacological result of the referred medication. 
Therefore, I believe that it should be published in another journal with a different
scope than this one.
