5.1 Pharmacodynamic properties
Phenolphthalein is an irritant purgative, usually taken at night to act in the morning.
Rhubarb is a mild anthraquinone purgative. It differs from other anthraquinone purgatives in that it exerts an astringent action after purgation.
5.2 Pharmacokinetic properties
Phenolphthalein is a diphenylmethane stimulant laxative. Up to 15% of phenolphthalein given by mouth is absorbed. Enterohepatic circulation occurs
and the active glucuronide is excreted in the bile.
Some excretion occurs in the urine. Phenolphthalein usually has an effect within six to eight hours but because of enterohepatic circulation its action may continue for several days. Rhubarb is an anthraquinone laxative. The active anthraquinones are liberated into the colon from the glycosides by colonic bacteria and an effect usually occurs 6 to 12 hours after administration. There is some absorption of the anthraquinones following hydrolysis. Excretion occurs in the urine and the faeces and also in other secretions including milk.
