What does antitussive mean?
An antitussive is any drug or agent that suppresses coughing, most often by dampening the cough reflex at its source in the brain. The term comes from Latin: 'tussis' means cough, and the prefix 'anti-' means against, so an antitussive is quite literally something that works against a cough. Antitussives are chiefly recommended for dry, hacking coughs that serve no useful purpose and disturb sleep, while productive coughs that clear mucus from the lungs are usually treated with expectorants instead — the pharmacological opposite of an antitussive. Familiar examples include dextromethorphan, found in many over-the-counter cold remedies, and codeine, which was long a mainstay of prescription cough syrups before restrictions on its use. Even simple household remedies such as honey are sometimes described as having mild antitussive effects. Though common in medical writing, the word rarely surfaces in casual conversation, where people simply say 'cough medicine' or 'cough suppressant'.

Etymology of antitussive
Antitussive derives from the Latin noun 'tussis', meaning cough, combined with the Greek-derived prefix 'anti-', meaning against. The compound entered English medical vocabulary in the late nineteenth or early twentieth century, when modern pharmacology began classifying cough remedies systematically. Its closest relative is the adjective 'tussive', used in phrases like 'tussive expiratory effort'; other words sharing the Latin root include 'pertussis', the medical name for whooping cough, which literally means 'intense cough'.
How antitussive is actually used
Antitussive is primarily a technical term used in medical and pharmaceutical contexts; in everyday speech people more often say 'cough suppressant' or 'cough medicine'. It appears both as a noun (an antitussive drug) and attributively as an adjective (antitussive properties).
Easily confused with antitussive
An expectorant helps bring up mucus from the airways, whereas an antitussive suppresses the cough reflex itself.
