Description and usage for Piriton tab:
Piriton products contain the active ingredient chlorphenamine maleate, which is a type of medicine called a sedating antihistamine.
It works by preventing the actions of histamine – a substance produced by the body when it reacts to a foreign substance such as pollen or pet fur (an allergen). Histamine causes a chain reaction that results in allergic symptoms. Chlorphenamine blocks histamine receptors and so stops this chain reaction.
Chlorphenamine is called a sedating antihistamine because it enters the brain in significant quantities and causes drowsiness.
