A demulcent cough drop

A demulcent (derived from the Latin: demulcere "caress"), sometimes called a mucoprotective agent, is a mucilaginous or oleaginous preparation[1] that forms a soothing protective film over a mucous membrane, relieving minor pain and inflammation of the membrane.[2][3][4] However, they generally help for less than 30 minutes.[5]

Demulcents are sometimes referred to as mucoprotective agents. Demulcents such as pectin, glycerin, honey, and syrup are common ingredients in cough mixtures and cough drops.[6]

Examples

[edit | edit source]

Natural demulcents include slippery elm, pectin, licorice-root and marsh-mallow (Althaea officinalis).

Synthetic demulcents include methylcellulose, propylene glycol, and glycerin.
