Topical vehicles

Medications are incorporated into "bases" or "vehicles" to facilitate their transportation and absorption by the skin to attain the desired therapeutic result. Vehicles may be comprised of one or more components ("phases").

Liquids, greases, and powders are "monophasic" vehicles. When combined as "biphasic" or "triphasic" vehicles, the resulting combinations are pastes, cooling pastes, creams, and shake lotions.

New techologies and vehicles incorporate liposomes and microparticles to topical medications.
