HOW DO ANTITUSSIVES WORK?

Antitussives are prescription or over-the-counter drugs used for suppressing cough.

Antitussives act on the cough center in the brain and decrease the sensitivity of cough receptors. When the cough receptors in the respiratory passages and lungs are stimulated, they send signals to the cough center located in the brain. The impulse generated travels down and stimulates the respiratory muscles to produce a cough. 

Antitussives relieve cough by:

  • Acting on the cough center in the brain
  • Decreasing the sensitivity of cough receptors
  • Interrupting cough impulse transmission
  • Numbing the cough receptors in the respiratory passages and lungs
