coughsuppressant

A cough suppressant, also known as an antitussive, is a medication that can relieve or reduce coughing. Coughing is a reflex that helps clear the airways of irritants, mucus, or foreign particles. However, persistent or unproductive coughing can be disruptive and uncomfortable. Cough suppressants work by either affecting the cough reflex in the brain or by acting on the respiratory tract.

There are two main types of cough suppressants: opioid and non-opioid. Opioid antitussives, such as codeine and hydrocodone, are typically available by prescription and work by depressing the cough center in the brainstem. Non-opioid antitussives are more common and include dextromethorphan, which is found in many over-the-counter cough medicines. Dextromethorphan also acts on the cough reflex in the brain but does not have the same addictive potential as opioid medications. Other non-opioid suppressants may work locally by coating the throat and reducing irritation.

Cough suppressants are generally used for dry, hacking coughs that do not produce mucus and are interfering with sleep or daily activities. They are not typically recommended for coughs that are producing phlegm, as coughing helps to clear the lungs. It is important to consult a healthcare professional to determine the cause of a cough and the most appropriate treatment, as suppressants may not be suitable for all types of coughs and can have side effects.
