Demulcent

Demulcent is a substance that relieves irritation of the mucous membranes in the mouth by forming a protective film. The term can also refer to a drug that has a soothing effect on irritated or inflamed internal body tissues.

Overview

Demulcents are often used to relieve respiratory tract inflammation and irritation. They are also used in the treatment of gastrointestinal conditions, where they can soothe and protect the lining of the stomach and intestines.

Mechanism of Action

Demulcents work by forming a protective barrier over the mucous membranes, which helps to shield them from further irritation or damage. This can help to reduce inflammation and promote healing.

Examples of Demulcents

Some common examples of demulcents include glycerin, honey, and certain types of herbs such as marshmallow root and slippery elm.

Uses in Medicine

In medicine, demulcents are often used in cough syrups and lozenges to soothe irritated throats and reduce coughing. They are also used in certain types of eye drops to relieve dryness and irritation.

Side Effects

While generally considered safe, some people may experience allergic reactions to certain demulcents. It's always important to discuss any potential side effects with a healthcare provider before starting a new medication.
