The active ingredient in aspirin is acetylsalicylic acid. Why would doctors recommend buffered aspirin, especially those with a "sensitive" stomach?

I think the word "Buffered" is the key.

Chemistry .
a. any substance or mixture of compounds that, added to a solution, is capable of neutralizing both acids and bases without appreciably changing the original acidity or alkalinity of the solution.
b. Also called buffer solution.  a solution containing such a substance.
