How does it work?
This medicine contains three active ingredients, pholcodine, chlorpheniramine and pseudoephedrine.
Pholcodine belongs to a group of medicines called the opioids. It is used to suppress dry or painful cough.
Coughing is a reflex response to irritation of the airways. It is useful for clearing mucus, dust and other particles from the throat and lungs. It is important because it reduces the amount of mucus, dust and bacteria in the airways that would otherwise make breathing difficult.
Sometimes, coughing can become overstimulated even when there is no mucus to clear from the lungs or throat. In this situation coughing serves no purpose and can become painful and frustrating.
Pholcodine is used to block the cough reflex in situations where the cough serves no purpose. It does so by calming the part of the brain that governs the coughing reflex.
Chlorpheniramine belongs to a group of medicines called sedating antihistamines. It works by preventing the actions of histamine.
Histamine is a chemical produced by the body in response to allergic or inflammatory stimuli. It binds to histamine (H1) receptors in many areas of the body, causing widening of the blood vessels and the release of other chemicals that add to the allergic or inflammatory response. In nasal allergies and colds this results in reddening and swelling of the tissues and increased mucus production from the lining of the nose. There is also irritation that causes sneezing and often redness and watering of the eyes.
Chlorpheniramine blocks histamine receptors, thus preventing the action of histamine and relieving the symptoms, such as nasal congestion, that it causes.
Chlorpheniramine passes from the blood into the brain, producing general sedation and supression of other brain functions, including the vomiting and coughing mechanisms.
Pseudoephedrine belongs to a group of medicines known as sympathomimetics. It is a decongestant and works by stimulating alpha adrenergic receptors.
In the lining of the nose and sinuses, pseudoephedrine acts on alpha receptors in the muscles of the blood vessel walls, causing them to contract. This results in a narrowing of the blood vessels and therefore decreased blood flow to the lining of the nose and sinuses. By decreasing blood flow, the amount of mucus production in the lining of the nose and sinuses is reduced, relieving nasal congestion.
The combination of these medicines is used to relieve dry, irritating coughs and associated nasal congestion.
