drug delivery

Drug delivery is a term that refers to the delivery of a pharmaceutical compound to humans or animals. Most common methods of delivery include the preferred non-invasive (through the mouth), nasal, pneumonial (inhalation), and rectal routes. Many medications, however, can not be delivered using these routes because they might be susceptible to degradation or are not incorporated efficiently. For this reason many protein and peptide drugs have to be delivered by injection. For example, many immunizations are based on the delivery of protein drugs and are often done by injection.
