Cough response to citric acid aerosol in occasional smokers
Abstract:
Twenty two normal women volunteers underwent a standard cough provocation test by inhaling solutions of citric acid of progressively increasing concentration. Eight were non-smokers, eight moderate smokers, and six occasional smokers. All the non-smokers and moderate smokers coughed. Moderate smokers tended to cough more than non-smokers, but not significantly so. None of the occasional smokers coughed at all (p less than 0.001). Possibly the ability to smoke occasionally with enjoyment is a marker for a diminished cough reflex.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
