How Carbocisteine Works

Carbocisteine works by breaking down the structure of mucus, making it less thick and sticky. This process helps in clearing mucus from the airways.

As a mucolytic agent, it helps in reducing the viscosity of mucus, facilitating easier expectoration.

This action can help improve airflow and reduce the risk of infections related to mucus build-up.
