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

==Ingredients== Some throat lozenges contain active ingredients such as benzocaine (anaesthetic), or amylmetacresol (mild antiseptic) or 2,4-Dichlorobenzyl alcohol (mild antiseptic) or 4-Hexylresorcinol (anaesthetic, antiseptic) or dextromethorphan (cough suppressant).
Many varieties such as Halls contain menthol, peppermint oil and/or spearmint as their active ingredient(s). Some may contain other essential oils (generally "cooling" ones) such as eucalyptus oil and methyl salicylate.
Non-menthol throat lozenges generally use either zinc gluconate glycine or pectin as an oral demulcent. Honey lozenges are also available.
The purpose of the throat lozenge is to calm the irritation that may be felt in the throat while swallowing, breathing, or even drinking certain fluids. However, one study found that excessive use of menthol cough drops can prolong coughs rather than relieve them.<ref>{{cite journal |author1=Johnson, Danika |author2=Robert Mead |author3=Korey Kennelty |author4=David Hahn |title=Menthol Cough Drops: Cause for Concern? |journal=Journal of the American Board of Family Medicine |date=March 2018 |volume=31 |issue=2 |pages=183–191 |doi=10.3122/jabfm.2018.02.170363 |pmid=29535234 |s2cid=3825988 |url=https://www.jabfm.org/content/31/2/183.full |access-date=19 December 2022|doi-access=free }}</ref>
==History== [[File:Frog In Your Throat Box 1.jpg|thumb|Early 20th century "Frog In Your Throat" box, containing lozenges made of cubeb, tolu balsam, liquorice, white horehound and wild cherry extracts]] Sweets to soothe the throat date back to 1000 BC in Egypt's Twentieth Dynasty, when they were made from honey flavored with citrus, herbs, and spices.{{citation-needed|date=September 2018}} In the 19th century, physicians discovered morphine and heroin, which suppress the cough reflex. Popular formulations of that era included Smith Brothers Cough Drops, first advertised in 1852, and Luden's, created in 1879. Concern over the risk of opioid dependence led to the development of alternative medications.<ref>{{Cite book |last=Panati |first=Charles |title=Panati's Extraordinary Origins of Everyday Things |url=https://archive.org/details/panatisextraordi0000pana_u5v0/page/258 |year=1989 |publisher=Harper & Row |location=New York |isbn=978-0060964191 |pages=[https://archive.org/details/panatisextraordi0000pana_u5v0/page/258 258–260] }}</ref>
