Each 5mL of PENTUSS syrup contains: diphenhydramine 14.08mg, ammonium chloride 138mg, sodium citrate 57.3mg and menthol 0.5mg.
PENTUSS is the brand name for the antitussive, anti-allergic and expectorant formulation that addresses cold, symptoms caused by allergic reactions and cough. This combination suppresses too much coughing and thins the mucus and promotes easy airway clearance.
Diphenhydramine is an antihistamine, whose mechanism of action involves inverse agonism of the histamine H1 receptor. It belongs to the class of first-generation antihistamines. Diphenhydramine relieves major allergic reactions such as running nose, sneezing and itching. It crosses the blood-brain barrier to act on the CNS and induce drowsiness.
Ammonium chloride is a potent expectorant, which reduces the mucus viscosity and thins it. It increases the mucus secretion in the respiratory tract and eases the expectoration.
Sodium citrate is the mucolytic agent that breaks down the hard phlegm and eases its elimination. Menthol relieves the non-productive cough and soothes the throat pain that is caused due to frequent coughing.
