Pharmacodynamics

Rheinanthrone stimulates peristalsis and increases fecal water content to increase the movement of feces through the large intestine 1 2.

Mechanism of action

Rheinanthrone appears to increase macrophage expression of cyclooxygenase 2 (COX2) which increases production of prostaglandin E2 (PGE2) 2. This increase in PGE2 is associated with a subsequent decrease in aquaporin 3 expression. The decreased expression of aquaporin 3 likely restricts reabsorption of water in the large intestine resulting in the laxative effect of rheinanthrone. Rheinanthrone also appears to stimulate peristalsis in the large intestine dependent on contact with the mucosal epithelium 2.

Absorption

About 10% of rheinanthrone is absorbed from the gut 6.
