Just a couple of things to keep in mind...
I saw some people suggesting misoprostol, but this may not be the best recommendation. There's some pretty nasty diarrhea associated with its use, so that's why it's not so common (besides teratogenicity).
The whole discussion mentioned 8 times the word Misoprostol and I have not seen my trick so allow me to share. This may help someone.
Case report:
Misoprostol: little secret of its helpfulness: Misoprostol at low dose did not cause diarrhea.
Male personal experience: using Misoprostol 100 milligrams a pill, 1 at a time.
First day: 100 mg only. No diarrhea.
Second day: 200 mg only. No diarrhea. (100 milligrams a time, 2 times a day.)
Third day: 300 mg only. No diarrhea. (100 milligrams a time, 3 times a day.)
Fourth day: 400 mg only. No diarrhea. (100 milligrams a time, 4 times a day.)
Fifth day: 500 mg only.
diarrhea. (100 or 200 milligrams a time, 4 times a day.)
What's the tip from this case?
Low dose of Misoprostol worked at rebuilding mucous layer in the GI tract (evidenced as the small stomach ulcer was healed in 1 week) and
did not cause diarrhea. Perhaps, this may help this poor patient somehow in his GI tract? (or fellow pharmacist with stomach ulcer)?
Patient will have to try 100 milligrams a day until patient finds own level of misoprostol that will not cause diarrhea.

Does Misoprostol has a potential to help in colon? Very likely yes. My clue: Misoprostol was potential helper in treating epithelial damage in mouth and colon.
