About the study

Please note that the trial is now closed completely.


The purpose of the study

In the TOPPITS trial, we aimed to find out whether a drug called a proton pump inhibitor (Lansoprazole) helps to control throat problems, such as feeling like you have a lump in your throat, catarrh (phlegm), sore throat, coughing to clear your throat, or hoarseness, which do not easily get better.  Although this research may not immediately help the people that took part in it, we hope that it will help people with throat problems in the future.
