Dextromethorphan + Pseudoephedrine + Triprolidine

This combination of dextromethorphan, pseudoephedrine and triprolidine brings together a cough suppressant, a decongestant and an antihistamine. Dextromethorphan is a safe and effective non-narcotic cough suppressant. It acts centrally, on the cough centre in the medulla. It is structurally related to morphine, but it has no ppainkilling or habit-forming properties, and in general it has little sedative activity.

Phenylephrine is a decongestant that shrinks the blood vessels in the nasal passage. It is used for temporary relief of a stuffy nose and of sinus and ear symptoms caused by the common cold, flu, allergies, sinusitis and bronchitis. It works by reducing swelling in the nose and ears, which eases discomfort and makes breathing easier.

Triprolidine is an antihistamine used to relieve symptoms of allergy, hay fever and the common cold. These symptoms include rash, watery eyes, itchy eyes, nose, throat and skin, cough, runny nose and sneezing. It is a potent competitive histamine H1-receptor antagonist of the pyrrolidine class, with mild central nervous system depressant properties that may cause drowsiness. It also blocks another natural substance, acetylcholine, and this helps dry up some body fluids, so symptoms such as watery eyes and a runny nose settle.
