Expectorants
Expectorants
Expectorants (/ɪkˈspɛktərənts/) are a type of medicine that help to expel mucus from the lungs and respiratory tract. They are often used to treat conditions such as bronchitis, pneumonia, and chronic obstructive pulmonary disease (COPD).
Etymology
The term "expectorant" comes from the Latin word "expectorare", which means "to expel from the chest". It is derived from "ex-", meaning "out", and "pectus", meaning "chest".
Types of Expectorants
There are several types of expectorants, including:
- Guaifenesin: This is the most common type of expectorant. It works by thinning the mucus in the airways, making it easier to cough up.
- Ipecacuanha: This is a powerful expectorant that is derived from the roots of the ipecacuanha plant. It is often used in cases of severe congestion.
- Potassium iodide: This is a type of expectorant that is often used to treat chronic respiratory conditions. It works by increasing the amount of mucus produced by the lungs, making it easier to cough up.
Related Terms
