How it works
Triprolidine provides symptomatic relief in conditions believed to depend wholly or partially 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. Pseudoephedrine has a direct and indirect sympathomimetic activity and is an orally effective upper respiratory decongestant. Pseudoephedrine is substantially less potent than ephedrine in producing both tachycardia and elevation of systolic blood pressure and considerably less potent in causing stimulation of the central nervous system. Dextromethorphan has an antitussive action. It controls coughs by depressing the medullary cough centre.
