Quizplus · Accepted Answer

Drugs may be absorbed by the mucous membranes of the mouth, throat, nose, eyes, rectum, vagina, and respiratory tracts. Some applications, such as nasal sprays, eye drops, and rectal suppositories for constipation, have a local effect. Others have a systemic effect, such as nitroglycerin tablet dissolved under the tongue (sublingual) to dilate coronary arteries and relieve the pain of angina pectoris. Inhalation is used to concentrate drugs locally in the lower respiratory passages or to produce systemic effects, such as general anesthesia.
