Topical Skin Drug Application

Topical Skin Drug Application

Topical drugs are applied directly to the skin surface. They include lotions, pastes, ointments, creams, powders, shampoos, and aerosol sprays. Topical medications are absorbed through the epidermal layer into the dermis. The extent of absorption depends on the vascularity of the region.

Nitroglycerin, fentanyl, nicotine, and certain supplemental hormone replacements are used for systemic effects. Most other topical medications are used for local effects. Ointments have a fatty base, which is an ideal vehicle for such drugs as antimicrobials and antiseptics. Typically, topical medications should be applied two or three times a day to achieve their therapeutic effect.
