Final answer:
The enteral routes of drug administration are sublingual, oral, and rectal.
Step-by-step explanation:
The enteral routes of drug administration are:
- Sublingual
- Oral
- Rectal
These routes involve the direct delivery of drugs into the gastrointestinal (GI) tract, either through the mouth (sublingual and oral) or the rectum (rectal). Sublingual administration involves placing the drug under the tongue, where it is absorbed into the bloodstream through the sublingual mucosa. Oral administration involves swallowing the drug, which then passes through the stomach and intestines before being absorbed into the bloodstream. Rectal administration involves inserting the drug into the rectum, where it is absorbed into the bloodstream through the rectal mucosa.
