Role of Menthol in cough syrup

Menthol stands out as a noteworthy compound in the pharmaceutical industry. It is often used in cough syrups and lozenges, likely with the intention of curtailing cough reflexes. Most studies have confirmed that elevated levels of Menthol applied to the skin and tasted on the tongue can induce anesthetic, analgesic, or desensitizing outcomes.

But what is the role of Menthol in cough syrups? Does it have any therapeutic effect? Let us discuss that in detail.

What is Menthol?

Menthol is a natural compound found in various plants, such as peppermint and eucalyptus. It is widely used in cough syrups and other over-the-counter medications due to its flavouring properties and potential therapeutic effects on respiratory symptoms. Here’s how menthol functions in cough syrup:

Therapeutic effects of Menthol

Soothing effect: Menthol has a cooling and soothing sensation when applied or ingested. In cough syrup, it can help relieve the irritation and discomfort in the throat that often accompanies a cough. It provides a temporary numbing effect on the throat’s sensory receptors, which may help reduce the urge to cough and provide a sense of relief.

Bronchodilation: Menthol has been shown to have mild bronchodilatory effects, meaning it can help widen the airways in the respiratory system. This can make breathing easier and more comfortable, especially for individuals experiencing mild respiratory congestion or narrowing of the air passages.

Cough reflex suppression: Menthol is believed to influence the cough reflex by affecting the sensitivity of the cough receptors in the throat and airways. It may help reduce the frequency and severity of coughing by modulating the brain’s response to irritants or stimuli.

Expectorant properties: Some menthol-containing cough syrups are formulated as expectorants. An expectorant helps to thin and loosen mucus in the airways, making it easier to clear the respiratory passages. Menthol can contribute to this by promoting increased fluid secretion in the respiratory tract, aiding in the removal of mucus.

Nasal decongestant: Menthol’s aromatic properties and cooling sensation can provide relief from nasal congestion, which often accompanies cough and cold symptoms. It can help open up congested nasal passages and provide a feeling of improved airflow.
