Enteral administration may be divided into three different categories, depending on the entrance point into the GI tract: oral (by mouth), gastric (through the stomach), and rectal (from the rectum).
A rudimentary form of "dry" enema is the use of a non-medicated glycerin suppository. [1] However, due to the relative hardness of the suppository – necessary for its insertion into the human body – before glycerin can act, it must be melted by the heat of the body, and hence it does not take effect for up to an hour.

The catheter was developed to make rectal access more practical and provide a way to deliver and retain liquid formulations in the distal rectum so that health practitioners can leverage the established benefits of rectal administration.

Because enemas work in 2–15 minutes, they do not allow sufficient time for a large fecal mass to soften.
