Pharmacology

This preparation is a mixture of antitussive, decongestant and antihistamine agent. Dextromethorphan is a safe, effective, non-narcotic antitussive agent which has a central action on the cough centre in the medulla. Although structurally related to Morphine, it has no analgesic and habit forming properties and in general it has little sedative activity. Phenylephrine is a decongestant that shrinks blood vessels in the nasal passage. Phenylephrine is used for the temporary relief of stuffy nose, sinus, and ear symptoms caused by the common cold, flu, allergies, sinusitis & bronchitis. This medication works by decreasing swelling in the nose and ears, thereby lessening discomfort and making it easier to breathe. 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/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 which may cause drowsiness. By antagonizing another natural substance acetylcholine, it helps dry up some body fluids to relieve symptoms such as watery eyes and runny nose.
