Topical drug administration delivers drugs directly to the site of action on the skin or mucous membranes, allowing for high local drug concentrations and reducing systemic side effects. This route of administration is non-invasive and does not require any special equipment or training.

a. Topical drug administration can have a rapid onset of action, but this is not a disadvantage.

Skin thickness, hydration, and blood flow can all affect the absorption of topically administered drugs. For example, drugs may be absorbed more readily through thin skin or skin that is well-hydrated. Blood flow to the skin can also affect absorption by altering the rate at which drugs are delivered to the absorption site.
