Diphenhydramine+Sodium Citrate+Ammonium Chloride+Pseudoephedrine is used in the treatment of cough.

This is a combination of four medicines: Diphenhydramine, sodium citrate, ammonium chloride and pseudoephedrine which relieve cold symptoms. Diphenhydramine is an antiallergic which relieves allergy symptoms like runny nose, watery eyes and sneezing. Sodium citrate is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out. Ammonium chloride is an expectorant which works by decreasing the stickiness of mucus (phlegm) and helps in their removal from the airways. Pseudoephedrine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose.
