A
throat lozenge (
cough drop,
troche,
cachou, or
cough sweet) is a small, typically medicated tablet intended to be dissolved slowly in the mouth to temporarily stop coughs and lubricate and soothe irritated tissues of the
throat (usually due to a
sore throat), possibly from the
common cold or
influenza. Cough tablets have taken the name
lozenge, based on their original shape, a diamond.
