Bisacodyl (C0005632)

Definition (MSH)A diphenylmethane stimulant laxative used for the treatment of constipation and for bowel evacuation. (From Martindale, The Extra Pharmacopoeia, 30th ed, p871)
Definition (NCI)A synthetic pyridinylmethylene-diacetate ester derivative stimulant laxative, Bisacodyl acts with a parasympathetic effect directly on mucosal sensory nerves, increasing peristaltic contractions. It is used for occasional constipation, in pre- and postoperative treatment, and in conditions that require facilitation of defecation. (NCI04)

Senna Extract (C0036656)

Definition (PDQ)An extract made from the dried leaflets on the pods of Cassia angustifolia or Cassia acutifolia with laxative properties. Dimeric glycosides in dried senna extract are converted to the active monoanthrones by bacterial action in the colon. Through direct effects on enterocytes, enteric neurons, and muscle, monoanthrones produce giant migrating colonic contractions in addition to water and electrolyte secretion. As do other stimulant laxatives, monoanthrones may induce a limited low-grade inflammation in the colon through activation of prostaglandin/cyclic AMP and nitric oxide/cyclic GMP pathways and perhaps inhibition of Na+, K+-ATPase.

("http://nciterms.nci.nih.gov:80/NCIBrowser/ConceptReport.jsp?dictionary=NCI_Thesaurus&code=C61324" NCI Thesaurus)
Definition (NCI)An extract from the leaves of senna plant belonging to the genus Cassia with laxative properties. Senna contains anthraquinone glycosides, which are the main active components of senna. Senna acts on and irritates the lining of the intestine wall, thereby causing increased intestinal muscle contractions leading to vigorous bowel movement. This decreases transit time and reduces the opportunity of fluid absorption from the feces, which enhances the laxative effect.
Definition (MSH)Preparations of Cassia senna and C. angustifolia (see SENNA PLANT). They contain sennosides, which are anthraquinone type CATHARTICS and are used in many different preparations as laxatives.

Cascara sagrada (C0205704)

Definition (MSH)Dried aged bark of a buckthorn, Frangula purshiana (FRANGULA), that contains the anthraquinone EMODIN and cascarosides. It is used as a laxative (CATHARTICS).
Definition (NCI)Used as a laxative in constipation and various medical conditions, Cascara (cascara sagrada) is dried bark of Picramnia sp. (Simarubaceae) or Rhamnus purshiana (Rhamnaceae) containing stimulant laxative anthranol glycosides that act on the intestinal wall to increase muscle contractions and encourage bowel movements.
