5. Pharmacological properties
5.1 Pharmacodynamic properties

Glycerin and sucrose have demulcent properties and will soothe irritated sore throats and possibly block sensory cough receptors within the respiratory tract.

5.2 Pharmacokinetic properties

Glycerin is readily absorbed from the gastrointestinal tract and undergoes extensive metabolism principally in the liver. It may be used in the synthesis of lipids, and is metabolised to glucose or glycogen or oxidised to carbon dioxide and water. It may also be excreted in the urine unchanged.

Sucrose is hydrolysed in the small intestine by the enzyme sucrase to glucose and fructose which are then absorbed.

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