How Henadryl Syrup works

Ammonium chloride is an expectorant which works by decreasing the stickiness of airway secretions and helps in their removal from the airways. Sodium citrate is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out. Diphenhydramine is an antiallergic which relieves allergy symptoms like runny nose, watery eyes and sneezing. Menthol is an organic compound which produces a sensation of coolness and relieves minor throat irritation.
