Paints are solutions or dispersions of one or more medicaments intended for application to the skin or, in some cases, to the mucous membrane. They contain a volatile solvent, which evaporates quickly to leave a dry or resinous film of drug. Throat paints are more viscous due to their high content of glycerin. They are sticky and adhere to the affected site, thereby prolonging the action of the medicaments. Paints should be kept in airtight containers. They should comply with the general requirements for labeling, in addition to the condition on the label, which states ‘For external use only.’
