Pharmacodynamics
Pharmacotherapeutic class: OTHER LAXATIVES, ATC code A06AX01
(A: Alimentary tract and metabolism)
Rectal route.
Glycerin suppositories cause rapid evacuation of the rectosigmoid by triggering the defecation reflex. Defecation occurs within 5 to 30 minutes after administration.
Glycerol stimulates peristaltic movements and decreases water reabsorption through its osmotic and hygroscopic properties. It also has a local irritant effect that contributes to the reflex defecation.
