Administration

Administration is the process by which a patient takes a medicine. There are three major categories of drug administration; enteral (via the human gastrointestinal tract), injection, and other (dermal, nasal, ophthalmic, otologic, and urogenital).

Oral administration, the most common form of enteral administration, can be performed in various dosage forms including pills, tablets, or capsules, and other routes likewise have various forms.

The drug may contain a single or multiple active ingredients.

They can be administered all at once as a bolus, at frequent intervals or continuously. Frequencies are often abbreviated from Latin, such as every 8 hours reading Q8H from Quaque VIII Hora.
