Topical

From Wikipedia, the free encyclopedia

In medicine, a topical medication is applied to body surfaces such as the skin or mucous membranes such as the vagina, penis, anus, throat, eye or the ear. Some hydrophobic chemicals such as steroid hormones can be absorbed into the body after being applied to the skin in the form of a cream, gel or lotion. Transdermal patches have become a popular means of administering some drugs for birth control, hormone replacement therapy, and prevention of motion sickness.

In dentistry, a topical medication may also mean one which is applied to the surface of teeth.

Chloramphenicol is an example of an antibiotic that may be used topically.
