5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Ammonium chloride and ammonium carbonate have an irritant effect on mucous membranes and are considered to have expectorant properties.
Guaiphenesin is thought to reduce the viscosity of tenacious sputum and has expectorant properties.
5.2 Pharmacokinetic Properties
Ammonium salts are effectively absorbed from the gastrointestinal tract. The ammonium ion is converted into urea in the liver; the anion thus liberated into the bloodstream and extracellular fluid causes a metabolic acidosis and decreases the pH of the urine, this is followed by a transient diuresis.
Guaiphenesin is absorbed from the gastrointestinal tract. It is metabolised and excreted in the urine.

There are no preclinical data of relevance to the prescriber which are additional to that already included.
