What are Expectorant Drugs?

Expectorants are medications that primarily help decrease the thickness of mucus to facilitate its clearance from the body by attaching themselves to the cells lining the respiratory tract and providing a source of water to hydrate the tissue. They are used in conjunction with other medications for cough relief, for the treatment of bronchitis and other types of respiratory infections, and more.

There are multiple factors driving growth within the global expectorant drugs market, including increasing incidence rates of respiratory disease triggered by environmental pollution; the increasing prevalence of self-medication; increasing ease of purchasing medications through both urban and suburban areas; and the focus of pharmaceutical companies on improving expectorant formulations and developing combination products. Overall, expectorant drugs are resilient to changes due to high volume sales across all age groups.
