Early decision is a binding option - best utilized if there is one program that you are dying to get into. If you choose a school - ONE SCHOOL - that is ED, and you get in, you are obligated to go to that school. Your application is NOT released to any other school.
However, if you choose a school that is ED and you do not get in, PharmCas will release your application to the rest of the schools for the regular admission process.
So, ED is not an option where you can apply to several schools and have a choice and just get a whole bunch of acceptances early. Doesn't work like that.
