The active ingredients are macrogol (PEG) 3350, sodium chloride, sodium bicarbonate and potassium chloride2. Basically, what Purgolene does is that it transports water to soften a dry, hard stool and causes an osmotic action in the gut, which creates a laxative effect2.
Purgolene has a lemon flavour, and contains no sugar as it uses 75,0 mg of acesulfame potassium (E950) as a sweetener.
It is suitable for the treatment of chronic constipation in adults, adolescents and the elderly. It is not suitable for children under the age of 12 years of age2.
