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

This is a combination of four medicines: Ammonium chloride, sodium citrate, diphenhydramine and phenylephrine which relieve cold symptoms. Ammonium chloride is an expectorant which works by decreasing the stickiness of mucus (phlegm) 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. Phenylephrine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose.
