Which route delivers medication through the skin?

• A. Topical
• B. Sublingual
• C. Buccal
• D. Oral

Answer: (A)

Topical administration involves applying medication to the skin. It can work locally on the skin, or be formulated as a patch that delivers medicine through the skin into the bloodstream for systemic effects. This is different from sublingual or buccal routes, which absorb through the tissues under the tongue or between the cheek and gums, and from the oral route, which is swallowed and absorbed through the digestive tract. So the route that delivers medication through the skin is topical.
