Drug delivery is an area of science that is concerned with the methods of
drug administration by the patient to treat diseases or protect against illnesses.
Drugs are delivered to various body tissues of man using a range of routes.
These include oral, parenteral, transdermal, pulmonary, intranasal and rectal
routes. Females have an additional route for administration, namely the
vaginal route which can be used to treat local diseases (i.e. within the vaginal
cavity) or systemic diseases.
