Bronchodilators or inhaled corticosteroids for postinfectious cough

Do bronchodilators or inhaled corticosteroids (ICS) help postinfectious cough (PIC) in adults without asthma? Data are limited, with results from only 2 ICS RCTs and 1 bronchodilator RCT. In adults, PIC scores may improve about 50% when taking placebo and about 5% to 10% more with ICS over 2 weeks
