Demulcent

Agent forming a soothing film over irritated mucous membranes

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
