Mechanism of Action
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. It is used to treat nasal and sinus congestion of the tubes that drain fluid from inner ear.
Triprolidine provides symptomatic relief in conditions believed to depend wholly or partly upon the triggered release of histamine. It is a potent competitive histamine H1-receptor antagonist of the pyrrolidine class with mild central nervous system depressant properties which may cause drowsiness.
