===Route of Adminstration===
Drugs can be given via a variety of routes. A choice of a specific route is determined by the following factors:
* the properties of the drug
* the therapeutic objective (eg speed on onset, length of duration)
* administration or restriction to a local site
Some of the route options are: oral, rectal, intravenous, intramuscular, sub-cutaneous, intra-articular, inhalation, transdermal patches, topical (eye, ear and nose drops), intramammary, intravaginal, epidural and sub-conjunctival.
'''Intravenous injections''' have the highest peak plasma concentrations after administration.
