Final answer:
Antitussive drugs are used to suppress or relieve coughing. They do not decrease sputum production, sneezing, edema, or inflammation. They specifically target and reduce coughing.
Step-by-step explanation:
Antitussive drugs are medications that are used to suppress or relieve coughing. They work by acting on the cough reflex in the brain and respiratory tract. Antitussives can be classified into two types: centrally acting antitussives, which suppress the cough reflex in the central nervous system, and peripherally acting antitussives, which act directly on the respiratory tract to reduce the sensitivity of the cough receptors.
Antitussive drugs do not decrease sputum production, sneezing, edema, or inflammation. They specifically target and reduce coughing, providing relief for conditions such as colds, flu, bronchitis, and certain respiratory diseases.
