From my text, parenteral is a route "other than alimentary canal" (e.g. intraosseus, intravenous, intra-arterial, intramuscular, mucosal), nonparenteral consists of oral and inhalation, and enteral is gastric feeding tube, oral, or rectal. I'm confused as to the relationship of "nonparenteral" and "enteral". Is one a subset of the other or what? If parenteral is non enteral, then isn't nonparenteral non non enteral which would be the same as enteral?

Nonparenteral is oral meds (pills, capsules, syrups, etc.), topical meds (ointments, patches like nitro), suppositories (vaginal and rectal), etc.
Pareneteral is anything injected into the body: intradermal, subcutaneous, intramuscular, intracardiac, and intravennous, etc. This includes parenteral nutrition.
Enteral is anything placed directly into the digestive tract: NG-tube, J-tube, PEG tube.
Hope this helped
