Ii know this response is a bit late but for the future.
In the GI tract, bismuth subsalicylate (Pepto Bismol) undergoes chemical dissociation to yield bismuth and salicylate. Bismuth absorption is negligible, and plasma levels of the salicylate are similar to levels achieved after a comparable dose of aspirin.
It takes about 33 hours for a dose of aspirin to be eliminated from your system.
