There are several methods of drug administration. They are: oral which is by mouth, its effect is slower and less efficient because they must be absorbed in the small intestine and then, depending on their molecular structures, are broken down or activated in the liver before being transported to the correct area of action (GCU, 2012). Another route is sublingual or buccal. These methods rely on the capillaries under the tongue or in the cheek for quick absorption. Medications such as nitroglycerin are given this way (GCU, 2012). A third method is topical. Medications given topically are applied to the skin and absorbed as they diffuse through the epidermis (GCU, 2012). A forth way is rectal. Medications may also be absorbed by the capillaries in the rectum. This is a useful route in patients who cannot take medications by mouth due to nausea, vomiting, or extreme disease of the mouth (GCU, 2012). A final way would be parenteral. This method involves administering medication intravenously, intradermal, subcutaneously, intramuscularly, and intrathecally (GCU, 2012). The best and most preferred route to give medication is orally. The…
