finding and removing the time in a cell

Hi, im working on a file that has alot of data and all i need to do is to find and remove the time which includes the AM/PM (attached file is an example). what i do is to use the find and use a condition *:*00*AM and *:*00*PM which brings me the cells and then remove the time manually without removing the words "Dropdate: 08/12/2014". I just wonder if there's a way to do this quicker, using replace or maybe a formula. the important thing is to leave the words Dropdate with the date.

Thanks in advance!
