Researchers in Singapore find that antipsychotic medications are associated with changes to colonic architecture, which could result in difficult colonoscopy and increased colonoscopy-related risks. Antidepressants, laxatives, benzodiazepines, and antihypertensive medications were not found to have significant effect on changes to colonic architecture. Results are available online in Surgical Endoscopy.
