The only two discussed within the current PepsiCo website are the following:
Caleb Bradham bought the name "Pep Kola" from a local competitor and changed it to Pepsi-Cola.
"Pepsi-Cola" is an anagram for "Episcopal" - a large church across the street from Bradham's drugstore. There is a plaque at the site of the original drugstore documenting this, though PepsiCo has denied this theory.
The word Pepsi comes from the Greek word "pepsi" (πέψη), which is a medical term, describing the food dissolving process within one's stomach. It is also a medical term, that describes a problem with one's stomach to dissolve foods properly.
Another theory is that Caleb Bradham and his customers simply thought the name sounded good or the fact that the drink had some kind of "pep" in it because it was a carbonated drink, they gave it the name "Pepsi".
