Routes of administration how the drug is introduced to the body. The
two most common routes of administration are oral and parenteral.
Oral administration the route of drug administration by way of the
mouth through swallowing. Parenteral administration the route of
drug administration that does not involve the GI tract. Although most
commonly administered by injection, parenteral administration also
technically includes routes such as inhalation and topical
administrations because they bypass the GI tract.
Oral administration is the
safest and most convenient. However, since it must go through the GI
tract the onset of action is delayed about 30-60 minutes compared to
parenteral administration, which is fairly immediate
Oral (PO)
30-60 min. Whenever possible the safest most convenient route. Most
