drug delivery

Show Summary Details

Quick Reference

The means whereby a drug reaches the appropriate compartment of the body, which depends on the properties of the drug and the site where it is required. Delivery may be oral if it resists degradation at high pH and can be absorbed by the intestine, or may be by inhalation, injection, or transdermal diffusion. Topical application is appropriate for some superficial sites, in which case systemic absorption may well be undesirable.
