Tác dụng
Description: Mechanism of Action: Senna is an anthraquinone stimulant laxative obtained from Cassia senna (Cassia acutifolia) and Cassia angustifolia. Its primary active cathartic principles are the stereoisomeric glucosides, sennosides A and B. As stimulant laxative, it induces defaecation by directly acting on intestinal mucosa or nerve plexus, thereby stimulating peristaltic activity on the intestine and increasing motility. Onset: Within 6-12 hours (may take up to 24 hours). Pharmacokinetics: Absorption: Minimally absorbed from the small intestine. Distribution: Enters breast milk (small amounts of active metabolites). Metabolism: Unabsorbed senna undergoes bacterial hydrolysis in the colon to release the pharmacologically active free anthraquinones, while absorbed senna undergoes hepatic metabolism. Excretion: Via urine and faeces.
