Aquaphen syrup is a mixture of expectorant, decongestant and antihistamine agent. Guaiphenesin has an expectorant action. It reduces sputum viscosity by increasing the volume and water content of the bronchial secretion thereby facilitating the expectoration of sputum. Pseudoephedrine has direct and indirect sympathomimetic activity and is an 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.Triporlidine 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. Aquaphen syrup is absorbed from the gastrointestinal tract. Guaiphenesin is metabolized and excreted in the urine. Pseudoephedrine is largely excreted unchanged in the urine together with small amounts of its hepatic metabolite and triprolidine is metabolized in the liver and excreted usually as motabolites in the urine.
