🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works as a stimulant laxative. After oral intake, phenolphthalein is partly absorbed and partly remains in the colon, where it directly irritates the mucosal lining and stimulates the intramural nerve plexuses of the large intestine. This stimulation increases colonic motility and reduces water absorption, leading to a softer stool and an urge to defecate. The action is mainly on the colon rather than the small intestine, which is why the effect is usually felt several hours after taking the tablet.
