Which of the following factors can affect the absorption of rectally administered drugs?
Rectal pH, the presence of stool in the rectum and blood flow to the rectum can all affect absorption of rectally administered drugs. For example, some drugs may require an acidic environment for optimal absorption and may be affected by changes in rectal pH. The presence of stool in the rectum can also affect absorption by altering contact between the drug and mucous membranes. Blood flow to the rectum can affect absorption by altering the rate at which drugs are delivered to the absorption site.
