Dextromethorphan Hydrobromide, Cetirizine, Phenylephrine, Ambroxol, Guaifenesin, Sodium Citrate

Dextromethorphan Hydrobromide, Cetirizine, Phenylephrine, Ambroxol, Guaifenesin, Sodium Citrate is a multi-ingredient medication that combines the actions of six active substances, each providing a unique therapeutic benefit. This medication is used for relieving the symptoms of coughs and colds, particularly those caused by allergies, hay fever, and the common cold.
The primary action of Dextromethorphan Hydrobromide is its ability to suppress cough reflex in the brain, thereby reducing the sensation of cough. It is commonly found in over-the-counter cough suppressants.
Cetirizine is an antihistamine that relieves the symptoms associated with allergic reactions, such as runny nose, sneezing, watery eyes, and itching of the nose and throat. It works by inhibiting the effects of histamine, a natural substance released during allergic reactions.
Phenylephrine is a nasal decongestant that shrinks swollen blood vessels in the nasal passages, relieving nasal congestion, and allowing for improved breathing. It also has a direct effect on the lungs, which aids in clearing mucus.
Ambroxol and Guaifenesin are expectorants, which help loosen mucus in the respiratory tract and makes it easier to cough up and clear from the lungs. Ambroxol has the added benefit of increasing the effectiveness of the ciliary movement, a process that helps in mucus clearance.
Finally, Sodium Citrate provides a soothing effect on the respiratory system by neutralizing the acidic pH of mucus, which may irritate the sensitive lining of the throat and cause discomfort.
