Step-by-step explanation:
Which Drug Is Used to Suppress a Cough?
The drug used to suppress a cough is an antitussive. Antitussives are substances which suppress the coughing reflex. Examples of antitussive medications include codeine and dextromethorphan. They can sometimes be combined with other drugs to tackle multiple symptoms of a cold or allergies. However, it's important to note that not all antitussive drugs are equally effective for everyone, and their usage, especially in children, should be carefully considered and advised by a healthcare professional. In contrast, antihistamines may help alleviate symptoms like a runny nose and watery eyes but are not primarily used to suppress coughs.
