Final answer:
Antibiotics are used to treat both pertussis and influenza. Dantitussives and expectorant drugs are specific to pertussis, while anti-inflammatories are used for pertussis.
Step-by-step explanation:
Antibiotics are the drugs used to treat both pertussis (whooping cough) and influenza (flu). These drugs are used to kill or inhibit the growth of bacteria in pertussis and to treat secondary bacterial infections that can occur with influenza. Dantitussives and expectorant drugs are specifically used to treat pertussis by suppressing coughing and promoting mucus expectoration respectively, while anti-inflammatories are used to reduce inflammation in the respiratory tract during pertussis.
